Introduction

Great Plains welcomes you to its growing family of new product owners. Your 6 Meter No-Till Air Drill has been designed with care and built by skilled workers using quality materials. Proper setup, maintenance, and safe operating practices will help you get years of satisfactory use from the machine.

Before placing the machine into service for the ﬁrst time, read and understand this manual, in particular the “Important Safety Information”, pages 5 to 24. Have all operators read this manual before allowing them to work with the machine.

Description of Unit

The NTA607 or NTA2007 is a pull-type integrated air drill seeder. The implement folds for narrow 3 m (119 inch) transport.

A hydraulic fan supplies the material delivery system. Ground-driven ﬂuted shafts below the hoppers meter the seed or fertilizer (the materials) into the air ﬂow. Meter chambers and tower manifolds evenly divide the material ﬂow, and deliver equal volumes to each opener row.

The cart has single or dual hoppers for separate or simultaneous delivery of seed and/or granulated dry fertilizer. A single-hopper conﬁguration may have liquid fertilizer saddle tanks. Each hopper has an independent metering system with user-preset inﬁnite ratio gearboxes. Console-controlled variable rate meter servos are optional.

The NTA607 or NTA2007 has double-disc Series 07 openers, suitable for conventional till and, minimum-till conditions. With optional coulters, the drill is suitable for moderate no-till conditions.

Brakes are standard on model NTA607 and optional on model NTA2007. Service brakes are operated by air or hydraulic lines to the tractor.

Hydraulic weight transfer (of cart weight to implement, and from implement centre section to wings) is standard. Other options include ﬁeld markers, tramline kits, high rate or small seeds ﬂutes, and alternate discs, scrapers and seed ﬁrmers.

Do not modify the drill except as instructed by Great Plains. Do not use attachments other than as provided by or authorized by Great Plains.

Intended Usage

Use the NTA607 or NTA2007 to seed and fertilize production-agriculture crops only.

The intended use requires that safety features are unimpaired, that machine systems be in proper working order, and that the material rates have been correctly conﬁgured and veriﬁed. Use only Great Plains authorized replacement parts.

Faults in safety features, including missing or illegible safety decals, must be remedied prior to machine use.

To keep the machine in proper working order, comply with operating instructions, perform periodic maintenance, and repair or replace worn or damaged parts.

This is a volumetric seeding implement. The provided seed rate charts (manual 167-085B) are based on materials which likely vary from yours. Grain size, grain shape, density, surface texture, foreign matter, treatments, coatings, humidity, ﬁeld speed, soil conditions and normal wear on tires and meters cause rates to vary from the charts. Calibration is essential for satisfactory results.

Important Safety Information

Look for Safety Symbol

The SAFETY ALERT SYMBOLa indicates there is a potential hazard to personal safety involved and extra safety precaution must be taken. When you see this symbol, be alert and carefully read the message that follows it. In addition to design and conﬁguration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.

Be Aware of Signal Words

Signal words designate a degree or level of hazard seriousness.

DANGER, and the colour Safety Red, indicate an imminent hazard which, if not avoided, will result in death or serious injury. This signal word is limited to the most extreme situations, typically for machine components that, for functional purposes, cannot be guarded.

WARNING, and the colour Safety Orange, indicate a potential hazard which, if not avoided, could result in death or serious injury, and includes hazards that are exposed when guards are removed. It may also be used to alert against unsafe practices.

CAUTION, and the colour Safety Yellowb, indicate a potential hazard which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

Prepare for Emergencies

▲ Be prepared if a ﬁre starts

▲ Keep a ﬁrst aid kit and ﬁre extinguisher handy.

▲ Keep emergency numbers for doctor, ambulance, hospital

and ﬁre department near phone.

Be Familiar with Safety Decals

▲ Read and understand “Safety Decals” on page 10,

thoroughly.

▲ Read all instructions noted on the decals.

▲ Keep decals clean. Replace damaged, faded and illegible

decals.

a. Symbols and colours in this manual, and on machine models NTA2007, are based on ANSI standard Z535.

Decals on model NTA607 are based on ISO standard 3864.

b. Graphic (language-free) safety decals, found on models NTA607, are generally on a Safety Yellow background regardless of hazard

severity. Rely on the decal illustrations and manual instructions, and not the colour, to classify the severity of the hazard.

2012-01-05 Table of Contents Index 166-372M

Page 10

6 NTA607 or NTA2007 Table of Contents Index Great Plains Manufacturing, Inc.

Wear Protective Equipment

▲ Wear protective clothing and equipment.

▲ Wear clothing and equipment appropriate for the job. Avoid

loose-ﬁtting clothing.

▲ Because prolonged exposure to loud noise can cause

hearing impairment or hearing loss, wear suitable hearing protection such as earmuffs or earplugs.

▲ Because operating equipment safely requires your full

attention, avoid wearing entertainment headphones while operating machinery.

Use A Safety Chain

▲ Use a safety chain to help control drawn machinery should

it separate from tractor draw-bar.

▲ Use a chain with a strength rating equal to or greater than

the gross weight of towed machinery.

▲ Attach chain to tractor draw-bar support or other speciﬁed

anchor location. Allow only enough slack in chain to permit turning.

▲ Replace chain if any links or end ﬁttings are broken,

stretched or damaged.

▲ Do not use safety chain for towing.

Avoid High Pressure Fluids

Escaping ﬂuid under pressure can penetrate the skin, causing serious injury.

▲ Avoid the hazard by relieving pressure before disconnecting

hydraulic lines.

▲ Use a piece of paper or cardboard, NOT BODY PARTS, to

check for suspected leaks.

▲ Wear protective gloves and safety glasses or goggles when

working with hydraulic systems.

▲ If an accident occurs, seek immediate medical assistance

from a physician familiar with this type of injury.

Minimize Radiation Exposure

The DICKEY-john® RVS III Radar is an intentional radiator of RF energy. Although its radiated energy level is far below the limits set by EN 61010-1:1993 A2:1995Chapter 12.4, it is advisable not to look directly into the face of the unit.

The radar must radiate toward the ground and at least 20 cm (8 inches) away from a human during use to comply with the RF human exposure limits as called out in FCC 47 CFR Sec.2.1091. DO NOT RE-MOUNT OR USE THE RADAR IN A MANNER INCONSISTENT WITH ITS DEFINED USE.

166-372M Table of Contents Index 2012-01-05

Page 11

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 7

Handle Chemicals Properly

Agricultural chemicals can be dangerous. Improper use can seriously injure persons, animals, plants, soil and property.

▲ Do not use liquid seed treatments with the NTA607 or

NTA2007.

▲ Read and follow chemical manufacturer’s instructions.

▲ Wear protective clothing.

▲ Handle all chemicals with care.

▲ Avoid inhaling smoke from any type of chemical ﬁre.

▲ Never drain, rinse or wash dispensers within 30m (100 feet)

of a freshwater source, nor at a car wash.

▲ Store or dispose of unused chemicals as speciﬁed by

chemical manufacturer.

▲ Dispose of empty chemical containers properly. Laws

generally require power rinsing or rinsing three times, followed by perforation of the container to prevent re-use.

Conﬁned Space

With materials loaded, or once used for hazardous fertilizers, or seeds with hazardous treatments, your hoppers may become “permit-required conﬁned spaces” under applicable statutes, regulations, insurance rules or business policy. The vent tube structure in the hoppers has features to assist escape, and is not for routine entry.

▲ A hopper that is full or merely appears full can be an

entrapment hazard. You can sink entirely into the material, or into an oxygen-deﬁcient void, and suffocate in a matter of seconds. Bridges and crusts are especially dangerous.

▲ When hazardous fumes are present, you can be quickly

overcome even with the hopper lid open.

▲ Do not enter a hopper for material loading, material

unloading, hopper cleaning or meter maintenance.

▲ Clean hopper by power washing from outside hopper top.

▲ Perform meter maintenance by removing meters from

bottom of empty hopper.

▲ If obstruction removal or repair requires hopper entry, have

the work performed by a team trained in conﬁned space procedures. See “Hopper Entry” on page 115.

Page 12

8 NTA607 or NTA2007 Table of Contents Index Great Plains Manufacturing, Inc.

Tire Safety

Tire changing can be dangerous and should be performed by trained personnel using correct tools and equipment.

▲ When inﬂating tires, use a clip-on chuck and extension hose

long enough for you to stand to one side–not in front of or over tire assembly. Use a safety cage if available.

▲ When removing and installing wheels, use wheel-handling

equipment adequate for weight involved.

Use Safety Lights and Devices

Slow-moving tractors and towed implements can create a hazard when driven on public roads. They are difﬁcult to see, especially at night.

▲ Use ﬂashing warning lights and turn signals whenever

driving on public roads.

Use lights and devices provided with implement

Keep Riders Off Machinery

Riders obstruct the operator’s view. Riders could be struck by foreign objects or thrown from the machine.

▲ Never allow children to operate equipment.

▲ Keep all bystanders away from machine during operation.

Transport Machinery Safely

Maximum transport speed for implement is 30 kph or 20 mph. Some rough terrains require a slower speed. Sudden braking can cause a towed load to swerve and upset.

▲ Do not exceed 30 kph or 20 mph. Never travel at a speed

which does not allow adequate control of steering and stopping. Reduce speed if drill is not equipped with brakes.

▲ Comply with state and local laws.

▲ Do not tow an implement that, when fully loaded, weighs

more than 1.5 times the weight of towing vehicle.

▲ Carry reﬂectors or ﬂags to mark drill in case of breakdown

on the road.

▲ Keep clear of overhead power lines and other obstructions

when transporting. Refer to transport dimensions under “Speciﬁcations and Capacities” on page 149.

▲ Do not fold or unfold the drill while the tractor is moving

Shutdown and Storage

▲ Unfold and lower drill.

▲ Block tires with wheel chocks provided.

▲ Detach and store drill in an area where children normally

do not play.

166-372M Table of Contents Index 2012-01-05

▲ Understand procedure before doing work. Use proper

tools and equipment. Refer to this manual. For brake work, see speciﬁc safety information beginning on page 123.

▲ Work in a clean, dry area.

▲ Unfold and lower the drill, put tractor in park, turn off

engine, and remove key before performing maintenance. If work must be performed with implement raised, use centre section lift lock and gauge lock channels provided.

▲ Make sure all moving parts have stopped and all system

pressure is relieved.

▲ Allow drill to cool completely.

▲ Disconnect battery ground cable (-) before servicing or

adjusting electrical systems.

▲ Welding: Disconnect battery ground. Protect hydraulic

lines. Avoid fumes from heated paint.

▲ Inspect all parts. Make sure parts are in good condition

Preparation and Setup

This section helps you prepare your tractor and NTA607 or NTA2007 for use, and covers seasonal tasks, and tasks when the tractor/drill conﬁguration changes.

Before using the NTA607 or NTA2007 in the ﬁeld, you must hitch the drill to a suitable tractor, inspect systems and level the drill. Before using the drill for the ﬁrst time, and periodically thereafter, certain adjustments and calibrations are required.

Initial Setup

See “Appendix B - Initial Setup” on page 167 and “Appendix C - Option Installation” on page 168 for pre-delivery items (normally completed by dealer), and ﬁrst-time/infrequent setup tasks, including:

❑ Install seed monitor console in tractor (page 167).

❑ Remove protective ﬁlm from large highway

reﬂectors.

❑ Set marker extension (page 100) and speed.

Seasonal Setup

On initial delivery, use with a new tractor, and seasonally, check and as necessary, complete these items before continuing to the routine setup items:

❑ Bleed hydraulic system (page 119).

❑ Wing levelling and alignment (page 133).

❑ Speed sensor calibration (DICKEY-john® Air Cart

Control manual).

❑ Blow out entire air system to remove condensation.

Check air ﬂow at each row, for evidence of plugging.

❑ De-grease exposed cylinder rods if so protected at

last storage.

Pre-Planting Setup

Complete this checklist before routine setup:

❑ Read and understand “Important Safety

Information” on page 5.

❑ Check that all working parts are moving freely, bolts

are tight, and cotter pins are spread.

❑ Check that all grease ﬁttings are in place and

lubricated. See “Lubrication and Scheduled Maintenance” on page 136.

❑ Check that all safety decals and reﬂectors are

correctly located and legible. Replace if damaged. See “Safety Decals” on page 10.

❑ Inﬂate tires to pressure recommended and tighten

wheel bolts as speciﬁed. See “Tire Inﬂation Chart” on page 152.

Hitching Tractor to Drill

Crushing Hazard: You may be severely injured or killed by being crushed between the tractor and drill. Do not stand or place any part of your body between drill and moving tractor. Stop tractor engine and set tractor parking brake before attaching cables and hoses.

1. With the drill still on the parking jack , check that

the drill cart frame is level. See “Heights and Levelling” on page 32 for details on setting level.

Implement Lift and Speed Error Risks: The frame must be level both for proper operation of the implement, and to avoid frequent re-calibration of the speed radar.

Refer to Figure 5

2. Move the tractor to near hitching position. Put the

tractor in Park and shut down the tractor. If the tractor draw bar height is incompatible with the drill hitch height, move and/or invert the hitch to match.

Hitch Failure Risk:

The hitch may be mounted inverted if necessary, but always have two (2) bolts in two holes of both tongue and hitch. See “Heights and Levelling” on page 32 for hitch adjustments.

3. Remove hitch pin.

Back tractor to align draw bar and drill hitch. Shut down tractor and remove key.

4. Use parking jack to lower drill tongue onto tractor

draw bar. Secure hitch to bar with pin. Secure pin with any means provided.

5. Securely attach safety chain to a tractor anchor of

sufﬁcient strength to control the drill in the event of a hitch failure.

6. Use crank to raise jack foot. Remove pin and jack.

Refer to Figure 6

7. Store jack on stob inside right tongue tube.

8. Connect hydraulic hoses (page 27).

9. Connect brake hoses (option, page 28).

10. Connect electrical cables (page 29).

Hydraulic Hose Hook-up

High Pressure Fluid Hazard:

Escaping ﬂuid under pressure can have sufﬁcient pressure to penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or cardboard, NOT BODY PARTS, to check for leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury.

Only trained personnel should work on system hydraulics!

Great Plains hydraulic hoses are colour coded to help you hook-up hoses to your tractor outlets. Hoses that go to the same remote valve have the same colour handles.

The fan pressure hose (black) must be connected to a circuit capable of continuous ﬂow at high volume.

Note: This implement is compatible only with tractors

having Closed Centre hydraulics.

Refer to Figure 7

To distinguish hoses on the same hydraulic circuit, refer to handle symbols. The hose with an extended-cylinder symbol feeds a cylinder base end. The hose with a retracted-cylinder symbol feeds a cylinder rod end.

For the hydraulic fan, connect the hose with a retracted cylinder symbol to the pressure side of the motor.

The fan motor further requires hook-up of a (third) case drain line, which returns lubricating/cooling ﬂuid.

Marker hoses are provided on the cart even if markers are not installed on the implement. See “Marker Hose

Tips” on page 167 prior to ﬁrst hitching.

Protecting Fan Hydraulic Motor Seals

Low Pressure (Case) Drain Connection:

11. Attach case drain hose to low pressure drain connection. See Notice at right.

12. Connect low pressure motor return hose, marked “SUMP”, to a high volume low pressure return port. The sump line is distinguished by a large (2.7cm / 1.06in diameter) quick coupler.

13. Connect hydraulic hoses to tractor remotes.

Green Marker / Auxiliary Blue Opener Lift Yellow Wing Fold / Weight Transfer / Lock Black Fan “SUMP” Sump “BRAKES” Hydraulic trailer brakes (Option)

Equipment Damage Risk:

Case Drain Hose must be attached ﬁrst, prior to inlet and return hoses being connected, to prevent damage to hydraulic motor seals. The case drain has the smaller 6.4 mm (1⁄4in) I.D. hose and small, ﬂat-face, low-seep connector. DO NOT connect the case drain line to a power-beyond port.

31733

Case Drain Hose must be detached last, to prevent damage to the fan motor. To allow pressure relief during temperature cycles, it is normal for this line to release small amounts of oil even when stored with the connector elevated.

Brake Hook-up (Option)

Two drill braking (trailer braking) systems are available:

• Dual-line air system (Figure 8), and

• Single-line hydraulic (Figure 9).

In both systems, the tractor’s trailer brake remote port(s) operate a hydraulic slave cylinder on the drill.

Tractor trailer braking systems are normally integrated with the tractor brakes, and operate the trailer brakes when tractor brakes are used during tractor movement.

The trailer braking system may or may not be integrated with the tractor parking brake system.

Trailer brakes typically are not automatically engaged when the tractor transmission is in Park, and may not be engaged by any tractor Emergency Brake.

Figure 8

Air Brake System

Braking Hazards: Make sure the operator understands when drill brakes are engaged and when they are released (make a record of tractor behaviour on page 44).

31227

Also understand and comply with tractor operational restrictions when trailer brakes are used. For example, it is generally necessary to inter-tie split brakes, and avoid differential (steering braking) if trailer brakes are used.

Air Brake Hook-up

Refer to Figure 10

14. Open petcock at reservoir tank. Drain any water from tank. Close petcock.

Refer to Figure 11

15. Inspect gladhands before connecting. Clean elastomer seal surfaces . Blow debris out of inlet ports. Check screen condition.

16. Connect the “Brake”, “Service” or “Control” line ﬁrst. This line is Blue-coded.

Figure 9

Hydraulic Brake System

31232

This line operates the drill brakes.

Page 33

Great Plains Manufacturing, Inc. Table of Contents Index Preparation and Setup 29

17. Connect the “Provision” or “Supply” line. This line is Red-coded.

The Provision line charges a reservoir tank on the drill. The Brake line operates a valve system which meters tank air to the master cylinder on the drill.

Braking Hazard:

Do not use the NTA607 with a “single-line” air brake system. This drill is designed for transport speeds that require an air brake system to be “dual-line”. A single-line tractor system cannot charge the tank that powers the drill brakes.

Roll-Away Hazard:

When unhitching, disconnect the red (control) line ﬁrst. This sets the brakes on the drill.

Hydraulic Brake Hook-up

Refer to Figure 12

This is a single hydraulic line, connected to the tractor “Brake” outlet.

The factory default connector is a 19 mm (3⁄4in) poppetstyle QD (Quick Disconnect). If this is incompatible with your tractor, it may be replaced by a connector that mates to, or can be adapted to:

19 mm (3⁄4in) male ORB (O-Ring Boss), or 19 mm (3⁄4in) female JIC (Joint Industry Conference,

37° ﬂare).

Stow Wheel Chocks

21. Verify that the tractor transmission is in Park, and that the tractor’s parking brake is set (per step 2).

Refer to Figure 15 and Figure 16

Two sets of wheel chocks (4 chocks total) are provided to secure the drill when parked. These provide the safety when installed ahead and behind the transport tires.

When not in use, the chocks are stored in holders mounted under each end of the walkboard. The chocks are held in place by gravity when correctly stowed in the holders.

22. Remove the chocks from the wheel on one side.

Roll-Away Hazard: If one chock is extremely difﬁcult to remove, and/or the drill moves signiﬁcantly when the chock is removed, investigate the cause before removing the chocks on the other side. If no tractor is hitched, or the tractor is not securely parked, the drill could roll away after chock removal, and cause an accident resulting in death, serious injury and substantial property damage.

23. Store one chock in the bottom of a holder,

upside-right, tall end of chock toward frame.

24. Store the other chock in the top channel guides of

the same holder, upside-down, short end toward frame.

25. Repeat step 22 through step 24 for the other side.

Heights and Levelling

All frame sections must be at the correct height and level to maintain even planting depth. The hitch height sets cart frame level, and must be at a consistent height to both maintain level, and maintain radar speed calibration.

Periodic frame-levelling adjustments should not be necessary. If you are having problems with uneven depth, check drill levelness and follow these procedures.

2. Unfold the drill fully (page 35).

3. Set the initial tongue height, tractor hitch, and changing implement hitch conﬁguration as necessary. Distance is measured at bottom of hitch to ground level

4. If desired height cannot be attained with normal range of hitch, hitch may be relocated in tongue bolt holes. Always have two bolts in use, through two sets of hitch holes and two sets of tongue holes.

Consistent Seeding Depth Risk:

Level frame in planting conditions. Failure to do so may result in implement not producing desired results.

Checking Drill Height

The drill is designed to operate with all sections of the main tool bar nominally:

65cm (25

planting depth of:

3.8cm (11⁄2in), and a

coulter (option) depth of:

5.1cm (2in).

Refer to Figure 18

Tool bar height is measured to the bottom of the tool bars on which the row units are mounted.

At the suggested default setting, the implement frame is level with the ground during planting, and the row units operate at their most consistent planting depth.

Your crop, soil conditions, disc wear and other factors may create a need to use a different tool bar height.

Refer to Figure 19

Tool bar height is set via combinations of spacer bushings on the rods of the master lift cylinders ahead of the implement centre section, described on page 86. The wing end tool bar heights are controlled by slave cylinders that stop retracting when the master cylinders stop. Only weight transfer adjustment is usually required for wing height (although eye bolt adjustment is available).

When checking tool bar height:

1. Move the drill to representative planting soil

2. Set hitch to planting height (page 32).

3. Unfold and lower the implement (page 35).

4. Pull forward a meter or so (a few feet) to put openers

Operating Instructions

This section covers general operating procedures. Experience, machine familiarity, and the following information will lead to efﬁcient operation and good working habits. Always operate farm machinery with safety in mind.

Pre-Start Checklist

Perform the following steps before transporting the NTA607 or NTA2007 drill to the ﬁeld.

High Pressure Fluid Hazard:

Escaping ﬂuid under pressure can have sufﬁcient pressure to penetrate the skin. Check all hydraulic lines and ﬁttings before applying pressure. Fluid escaping from a very small hole can be almost invisible. Use paper or cardboard, not body parts, and wear heavy gloves to check for suspected leaks. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury.

❑ Review “Important Safety Information” on page 5.

❑ Lubricate as indicated at “Lubrication and

Scheduled Maintenance” on page 136.

❑ Check all tires for proper inﬂation. See “Tire

Inﬂation Chart” on page 152.

❑ Check all bolts, pins, and fasteners. Torque as

shown in “Torque Values Chart” on page 153.

❑ Check drill for worn or damaged parts. Repair or

replace parts before going to the ﬁeld.

❑ Check hydraulic hoses, ﬁttings, and cylinders for

leaks. Repair or replace before going to the ﬁeld.

Unfolding and Folding

Unfold/Fold: Safety Information

Overhead crushing hazard:

Unfold and fold implement only if fold hydraulics are bled free of air and fully charged with hydraulic oil. Keep away and keep others away when unfolding or folding.

Electrocution Hazard:

Keep clear of overhead power lines when unfolding, operating, folding or transporting the drill. Machine is notgrounded. At higher voltages, electrocution can occur without direct contact. Any line voltage present on implement, cart or tractor can cause severe injury or death.

Pinch Point and Crushing Hazards:

Keep people away from the drill and tractor during folding. Risks include pinching or crushing at pivot points and at multiple sites in pivoting assemblies.

Use wing fold locks. If a hydraulic failure occurs, or hydraulic levers are moved, unlocked wings could fall suddenly causing a major road accident, or crushing anything near the wings, resulting in death or serious injury, and property damage.

Falling Hazard - Tires Not a Step: Do not use tires as steps or platforms. All tires can be in light ground contact, or free to spin, when implement is lowered. Wing gauge wheel tires are off the ground in lift.

Wing Tilt Risk:

Fold only on hard level ground. if parked across a slope, wing lock bars could be difﬁcult or impossible to engage or release.

Unfold/Fold: About the Hydraulics

Part of the unfold/fold operation involves the Lift circuit. To meet highway clearance requirements, the wing gauge wheels are in the Lowered conﬁguration during fold, and are moved to the Raised conﬁguration prior to unfold.

The seed monitor does not need to be active during unfold. When the implement is raised, with the seed monitor off, the wing solenoid valves default to Fold circuit enabled.

Equipment Damage Risk:

Raise implement before unfolding or folding. Folding with openers lowered causes wing inside rows to dig or drag sideways. Machine damage is likely.

Lowering and Raising Drill

Lowering/Raising Safety Information

Crushing Hazard During Lowering:

Stay clear of wings and openers during lowering and raising. Wings are extremely heavy and are driven down with hydraulic pressure. Coulters and opener discs are sharp. During lowering, openers will cut or crush anything beneath them, and can cause serious injury or death.

Crushing Hazard While Raised:

Use lift lock (page 38) and gauge wheel lock channels when working above or beside openers.

Without locks, centre section and wings are held up only by hydraulic pressure, and slowly lower over time. They may lower more rapidly if the hydraulic system is damaged. They lower rapidly if the hydraulics fail, or the Lift circuit is set to Float or Retract.

Shoving Hazard:

Drill length changes by 56 cm (22in) during raising and lowering. Injury is possible.

Implement casters and row units move forward during raising, and backward during lowering. Gauge wheels move forward during lowering. Casters may swivel. Tractor may move in some circumstances.

Set tractor brakes / use Park to avoid tractor movement. Remain clear of all tires and row units during raise and lower.

Equipment Damage Risk:

Do not lower while any folding or unfolding operations are under way or partially complete. Openers can dig in or drag on ground and be damaged.

Note: Gauge wheel lock channels are provided to hold

the wings of an unfolded implement at the fully raised position, for maintenance only. These channels are an important safety feature for maintenance, but are not used in normal operations.

2012-01-05 Table of Contents Index 166-372M

Page 44

40 NTA607 or NTA2007 Table of Contents Index Great Plains Manufacturing, Inc.

Lowering

Refer to Figure 29

1. Check that maintenance lock channels are not installed on gauge wheel lift cylinders.

2. Check that centre section lift lock is disengaged. If not:

• If lock cylinder is extended, perform a brief unfold

operation (Extend the Fold circuit) to retract the lock cylinder.

• If the lock cylinder will not retract, perform a brief

Lift operation (Extend the Lift circuit) to free the pawl. If this fails to disengage the lock, see “Lift Lock Troubleshooting” on page 105.

3. Unfold drill before lowering (page 35).

4. Make sure all persons are clear of opener sections.

Refer to Figure 30

5. Activate dedicated lift circuit (normally Retract).

Figure 29

Lift Lock Disengaged

31249

Falling Hazard: Do not stand on tires when implement is lowered. Wing gauge wheels, caster wheels, and seed cart wheels, may have little or no weight on them, and may turn suddenly and without warning if used as a step, resulting in serious injury.

Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 41

Raising

Equipment Damage Risk:

Raise the implement for folding and unfolding. If lowered, inside wing openers drag or dig sideways during fold/unfold, and damage is likely.

Equipment Damage Risk:

Always raise the implement for tight turns and reverse/backing operations. Backing with openers lowered causes row unit plugging, and may cause opener damage. Tight turns with openers lowered may damage openers near the turn centre.

1. Make sure all persons are clear of opener sections.

2. Activate dedicated Lift circuit (normally Extend).

Refer to Figure 31

3. Extend cylinders until all sections are raised. Hold for a few seconds to re-phase cylinders.

4. Set circuit to Neutral to temporarily hold sections at raised.

Raising: Centre Lift Lock

For convenience during ﬁeld turns, the centre section lift lock does not automatically engage during lift. The lock does automatically engage during full fold. To engage the lock without folding, follow these additional steps:

Refer to Figure 32

5. Verify that all persons are safely clear of implement sections.

6. Have an observer stand where the observer can see the lock cylinder, and the tractor operator can see the observer.

7. Press “Enable Fold” softkey on seed monitor.

8. Activate the Fold circuit for folding (typically Retract). Hold at fold until the observer signals that the lock cylinder has extended. The lock cylinder normally extends early in the fold cycle.

9. Gradually move the Fold circuit to neutral, to allow any wing folding to reverse, by not cause the lock cylinder to retract.

10. Lower the implement until stopped by the lock. This also prevents the lock from releasing. Set the Lift circuit to neutral.

Note: Gauge wheel lock channels are provided to hold an

unfolded implement at the fully raised position, for maintenance only. These channels are an important safety feature for maintenance, but are not used in normal operations.

Equipment Damage Risk:

On tractors with electronic timer controls for hydraulic circuits, lift timers must be set to no more than 2 seconds longer than needed to fully raise drill. To reduce oil heating and system wear, Do Not Set for Continuous Mode.

Regulatory Requirement:

Unless the gauge wheels are in the lowered (tucked) positions when the drill is folded, the drill may not meet transport clearance requirements that apply to your operations.

Transporting the Air Drill

Transport Safety Information

Inadequate Tractor Hazard:

Tractor must weight at least 67% of the drill as towed. Ensure that the towing vehicle is adequate for the task. Using an inadequate tow vehicle is extremely unsafe, and can result in loss of control, serious injury and death. See table on next page. Do not tow if drill exceeds the load rating of the vehicle. Check Bridge Loads: A loaded drill can exceed the load ratings of bridges you must cross.

Excessive Speed Hazard:

Maximum transport speed is 30 kph or 20 mph at all times, and lower with a lighter tractor. Excess speed can result in loss of control or inability to stop. Reduce speeds with materials loaded, or if road conditions are less than ideal.

WARNING

EXCESSIVE SPEED HAZARD

To Prevent Serious Injury or Death:

Do Not exceed 20 mph maximum transport speed. Loss of vehicle control and/or machine can result.

818188C Rev C

Unexpected Wing Tilt-Down and Lowering Hazards:

Use wing fold locks (page 37). Check that implement centre section lift lock is engaged (page 38). Failure to use these safety features can cause a major accident resulting in death, injury and equipment damage. If locks are not engaged, and a hydraulic failure occurs, or a circuit is unintentionally set to Float, wings can unfold to ground contact, or implement can settle into ground contact.

Loss of Control Hazard, Tires: Inﬂate tires to factory speciﬁcations. Tighten wheel nuts to speciﬁcations. Under-inﬂated tires or loose nuts can cause loss of control. Over-inﬂated tires or overt-tightened nuts can fail suddenly and cause loss of control. Loss of control can cause a major accident resulting in death, injury and equipment damage.

Collision Hazard:

Check lights and reﬂector regularly. Replace bulbs and faded/worn/missing decals as required. Use lights in transport. These features are critical to visibility, particularly with other drivers unfamiliar with farm equipment or not expecting to encounter a slow-moving vehicle.

Note: An installation of optional brakes on the drill does

not reduce tractor capability requirements or increase allowed maximum transport speed.

Tractor Requirements

The ﬁgures in the table below represent a limited number of conﬁgurations. The weight of your drill can vary by hundreds of pounds, even if it is the same base model, due to installed options and/or after-market equipment.

If your tractor weight or capability is in question, take your empty drill to a scale and get a precise weight.

31153

Transport Checklist

❑ Plan the route. Avoid steep hills. Keep clearances in

mind. Folded, your NTA607 or NTA2007 is nearly 4m (13ft) high and is 3m (9.75ft) wide.

❑ Hitch.

Make hydraulic, electrical and optional braking connections. See “Hitching Tractor to Drill” on page 26.

❑ Close hopper lids (page 47).

❑ Check that ladders (page 46) and markers (page 62)

are stowed.

❑ If unfolded, raise, fold and lock.

See “Folding” on page 37.

❑ With tractor in Park, remove the wheel chocks

(page 31).

❑ NTA607 only: Set rear beacon switch to ON.

❑ Always have lights on for highway operation.

❑ Comply with all national, regional and local safety

laws when travelling on public roads.

❑ Release all brakes and travel with caution.

Material may be loaded prior to travel, but increases stopping distance, increases the need for caution in turns and braking, and increases tire and brake wear.

Brake Operation

Main transport wheel brakes are standard on model NTA607. Brakes are not standard on model NTA2007. There are brake shoe pairs on each of the four forward main transport wheels. The shoe pairs are operated by an air system on the drill. The “service” or “trailer brake” system is controlled by the tractor. It is connected to the tractor with a single hydraulic line or two air lines.

See also: page 28 - “Brake Hook-up (Option)” page 106 - “Brake Troubleshooting (Option)” page 123 - “Brake Maintenance (Option)”

Service Brake Operation

If optional brakes are installed and connected, the hydraulic/hydraulic or air/hydraulic systems automatically work in conjunction with the tractor’s own brakes.

Application and release of tractor brakes during tractor motion applies and releases the service brake system on the drill.

Know Your Tractor Systems:

Application of tractor Parking and/or Emergency brakes may or may not operate the drill service brake system, depending on the design of the tractor systems.

Consult your tractor manual for details on when remote brake ports are engaged and released. Note any variance from general behaviour in the table at right. Make sure the tractor operator knows when drill brakes are engaged and released.

Ladder Operations

A ladder is provided on the left end of the cart walkboard for material loading and routine lid/hopper maintenance. This ladder pivots vertically, and is held in the raised position by a spring-loaded pin. A gas piston regulates tilting speed minimizing risk of injury during lowering.

Ladder Safety Information

Overhead Ladder Hazard:

Falling Hazard:

Never allow riders on the walkboard. Use only the ladder to ascend the cart. Always face the cart when ascending or descending the ladder. Use the hand-holds and handrails. Make sure raised ladders are latched. A fall from the ladder or walkboard could result in serious injury or death.

Regulatory Requirement:

Raise and latch the ladder for transport. A lowered ladder may not meet highway clearance requirements that apply to your operations.

Make sure horizontal pin at ladder left, near pivot, is fully engaged when ladder is in the raised position. If the ladder is not pinned in the raised position, it could swing down and strike someone, or pinch a hand or arm, resulting in serious injury. Always check the horizontal capture pin if you did not personally set it when raising the ladder.

Deploying Ladder

Refer to Figure 35

1. Use one hand to hold the ladder up, while pulling horizontal pin to the right.

2. Carefully swing ladder out and down.

Using Ladder

1. Ascend and descend the ladder while facing the drill.

2. Use the handrails when on the higher steps.

Raising Ladder

1. Swing the ladder up. The pin engages automatically, and does not need to be held open.

2. Check that the tip of the pin is visible at the outside of the ladder frame.

Hopper and Tank Lid Operations

Hopper Lid Operation begin on this page. Tank Lid Operation begins on page 49.

Hopper Lid Safety Information

Entrapment and Rapid Suffocation Hazard:

Never enter a hopper for loading, unloading or routine maintenance. Leave strainer in place except when instructed to remove it. Keep lid tightly closed during operations. Keep lid locked closed or, during storage, locked slightly open. Store ladder to discourage access to lid area. Keep children away from drill.

▲ A hopper that is full, or merely appears full, can be an

entrapment hazard. You can sink entirely into the grain, or into an oxygen-deﬁcient void, and suffocate in a matter of seconds. Grain bridges and crusts are especially dangerous.

▲ When hazardous fumes or low oxygen levels are present,

you can be quickly overcome even in an empty hopper with the lid open. There may be no odours to alert you to the hazard.

Blowing Debris and Inhalation Hazards:

Turn off fan before opening hopper lids. Wear eye protection and dust mask or respirator. Hoppers are mildly pressurized and air is circulating in the hopper when the fan is running. Opening a lid with the fan running can expose you to blowing seed, fertilizer and treatment chemicals. Even with the fan off, adding seed or fertilizer will create a dust cloud. Risks include exposure to hazardous chemicals, lung and eye irritation.

Planting Consistency Risk:

Check lid seals for damage at frequent intervals. Check that latch closes lid tightly. Check hopper pressure reported by the seed monitor. Avoid metering problems caused by air leaks. Air leaks can cause irregular metering of materials.

Hopper Lid Operation

Keep lids closed. Keep tightly closed for operations. Keep loosely closed for storage. Open only for material loading, hopper clean-out and exceptional maintenance.

3. Move hook clear of U-bolt and re-close handle.

4. Lift lid slightly at pivot end to clear strainer .

1 2

5. Swing lid away from strainer. Open only enough to accomplish the present task.

Inspect Strainer and Hopper

Each hopper is equipped with a strainer intended to:

• capture large foreign matter in seed and materials,

• prevent entry by animals if lid left open, and;

Figure 36

Hopper Lid Latched

32461

• discourage hopper entry by children.

The strainer is secured by two bolts. Leave the strainer in place except during strainer and hopper cleaning.

6. Each time the lid is opened, inspect the strainer for debris, and if clear, inspect the hopper itself.

7. If the strainer needs to be removed for cleaning, do

not perform these steps until immediately ready to clean the strainer and return it to the hopper:

• Wear gloves suitable for protection against recent

fertilizers or seed treatments.

• Fully open the hopper lid.

Figure 37

Hopper Lid Open

32461

• Remove the strainer bolts.

• Lift the strainer out of the hopper.

• Immediately close and latch the lid (below).

• Clean and dry the strainer.

• Return it to the hopper. Re-install bolts.

Lid Closing

1. Swing lid over opening until capture hook is centred on U-bolt shackle.

2. Open handle and engage hook on shackle .

3. Close handle for operations or short-term parking.

1 2 3

For long-term storage, do not engage hook or latch handle, to avoid deforming the seal.

4. For storage, particularly unlatched, a padlock through both U-bolts deters unauthorized entry by persons unaware of possible conﬁned space risks, and prevents entry of pests, debris and precipitation.

• On the air inlet (front) side: Calibration

(for meter sampling and meter clean-out)

The doors are closed during transport, loading and planting. They may be open slightly in storage to allow drainage of condensation.

The doors need to close and seal tightly during planting. Periodically inspect the lever clamps for proper tension, and inspect the elastomer seals for integrity and resiliency.

Meter Door Opening

1. Lower the meter chute. Push the latch back (toward cart centre). Pull the outside end of the chute to the outside and down.

2. There are two interconnected clamp handles on each door. Pull out on a clamp handle . The door normally swings down on its own. If not, pull it open by hand.

Meter Door Closing

Make sure the clamp handles are out or down (not up), or it will not be possible to close the door.

1. Use a clean rag to wipe any residual material from the face of the elastomer seals on the door, and from the bottom face of the meter box.

2. Swing the door up into closed position.

3. While holding the door closed, swing the clamp handles up, until the toggle arms are past vertical.

4. Inspect the door closure for possible air leaks. Replace any deformed elastomer seal or damaged latch clamp.

5. Raise the meter chute. Pull it away from cart centre. Engage the latch handle under the washer.

Meter Doors Open

Material Loss / Air leak Risks: Do not open the clean-out door (the rear door at the air outlet side) until preparations have been made to capture any material to be re-used. Any material present will ﬂow immediately, possibly in large volume, as soon as the door is open. It is not possible to close the door with an adequate air seal, until the hopper is empty.

Loading Hopper Materials

1. Take appropriate precautions for handling materials. Whether using auger or hand-loading, dust is likely. Review Materials Safety Data Sheets (MSDS).

2. Review hopper lid safety information on page 47.

3. The implement does not need to be in any particular conﬁguration for material loading. Raising it, however, does reduce the hitch load.

Loading Material Safely

Entrapment and Rapid Suffocation Hazard:

Never enter a hopper for loading or unloading.

▲ A hopper that is full or merely appears full can be an

entrapment hazard. You can sink entirely into the grain, or into an oxygen-deﬁcient void, and suffocate in a matter of seconds. Grain bridges and crusts are especially dangerous.

▲ When hazardous fumes or low oxygen levels are present,

you can be quickly overcome even in an empty hopper with the hopper lid open.

Agricultural chemicals can be dangerous, including treatments on seeds and components of fertilizers. Improper use can seriously injure persons, animals, plants, soil and property.

▲ Read and follow chemical manufacturer’s instructions.

▲ Wear protective clothing.

▲ Handle all chemicals with care.

▲ Avoid inhaling smoke from any type of chemical ﬁre.

▲ Store or dispose of unused chemicals as speciﬁed by

chemical manufacturer.

▲ Dispose of empty chemical containers properly. Laws

generally require power rinsing or rinsing three times, followed by perforation of the container to prevent re-use.

Loading: Do Not Enter Hoppers

With material present, and once used for hazardous fertilizers, or seeds with hazardous treatments, your hoppers may become “permit-required conﬁned spaces” under applicable statutes, regulations, insurance rules or business policy. The venting tube structure in the hoppers has rungs for escape, and is not an entry ladder.

Loading: Check Strap Tension

4. Check hopper strap tension prior to every material load on a new drill, and again after material is loaded. See page 111.

Loading Seed or Dry Fertilizer

Loading: Use a Tractor

5. Securely hitch drill to a tractor with adequate weight and power. Park drill on solid, level ground. See Tractor Requirements, “Speciﬁcations and Capacities” on page 149. If a suitable tractor is not available, ensure that the tongue jack is on solid ground, and block multiple tires.

6. Lower the ladder on one side (page 46).

Loading: Select Hoppers to Use

Refer to Figure 41

Single-Hopper Conﬁguration

For single-hopper drills, all materials are delivered to the row unit seed tubes, and are placed in furrow.

Dual-Hopper Single-Shoot Conﬁguration

On a dual-hopper “single-shoot” drill, either hopper may be used for seed and/or fertilizer. All materials are delivered to the row unit seed tubes, and are placed in furrow.

If applying the same material from both hoppers, you can meter from both simultaneously, or from one at a time, sequentially. For sequential metering, the unused hopper is disabled by removing a ﬁnal Range gear.

Simultaneous metering avoids weight imbalance and eliminates stopping before the halfway point for meter change-over. However, avoid simultaneous metering if it would result in a Low Range variable rate gearbox setting below a scale value of 20.

If metering simultaneously, set each meter for one half the chart (or calibrated) rate. Do not merely use half the single-meter scale setting, as this is usually not half the rate. See “Setting Material Rates” on page 69, and the Seed Rate Chart Manual for more details.

Dual-Hopper Double-Shoot Conﬁguration

Hopper Intended Hopper Use

I (Left) Seed or In-Furrow Dry Fertilizer

II (Right) Dry Fertilizer or Broadcast Seed

Variable Hitch Load:

Loading materials increases the hitch load. With the implement lowered, and its circuits in Float, a full material load results in a hitch load of nearly 1900 kg (4200 pounds). This results in a jack load of up to 25 kg/cm2(350 psi). Even if the currently dry ground supports the jack, sudden wet weather could result in the jack becoming mired.

Material Mis-Application Risk:

Before ﬁlling the drill for the ﬁrst time, and at the beginning of each season, check the entire bin for leaks. A small air leak can cause large variations in seeding rates.

and meter bottom ﬂanges clean. Close and latch doors.

9. If the drill has been parked for more than a day, condensation may have caused moisture to accumulate. Whether or not meter doors are opened, run the fan system for several minutes to blow moisture out of the meters, primary and secondary seed hoses.

10. With the fan running, check hopper-lid and meterbox seals carefully for air leaks. Adjust bin latch or replace seals to prevent leakage.

Loading: Prepare Hopper(s)

11. Shut off all hydraulic power to the drill (unless using a tractor or cart circuit for an auger).

12. Open lid of hopper to be loaded (page 47).

13. Check that the strainer basket is in place in the top of the bin. Remove any foreign material from basket.

Planning Re-Loads

The seed monitor has a level sensor in each hopper to warn when seed box is empty. Alerts occur at the following approximate level of remaining material: 2890 litre (82 bu) hopper: 25 litres (0.7 bu) 5290 litre (150 bu) hopper: 25 litres (0.7 bu).

Entanglement and High Pressure Fluid Hazards:

Never operate an auger without guards. Wear gloves and eye protection when making/breaking auger hydraulic connections. Follow all auger manufacturer instructions for safe auger operation.

Loading Liquid Fertilizer (Option)

Agricultural Chemical Hazards:

Avoid contact with skin or eyes. Wear proper protective equipment as required by chemical manufacturer. Avoid prolonged breathing of chemical fumes. Wear respirator as required by chemical manufacturer. Some chemicals will cause serious burns, lung damage and death. Seek medical assistance immediately if accident occurs. Know what to do in case of an accident.

Tongue Weight Hazard:

Hitch to tractor, or ensure that tongue jack is on an adequate surface. Filling the liquid fertilizer tanks adds nearly 2200 kg (4800 pounds) to the cart, much of which may be borne by the tongue. On soft ground, or in the event of sudden rain, the parking jack could sink into the ground.

Inconsistent Rate Risk:

Use only pre-mixed liquid fertilizers. If using a pre-mixed fertilizer that tends to separate, sediment or stratify, load only immediately before use. The tanks of the optional liquid fertilizer system do not include agitators.

Tank Loading: All Methods

Tank ﬁll level is reported by a sight gauge on each tank. The table at right converts the scale levels to litres.

Refer to Figure 44 on page 55 and Figure 143 on page 166

1. Hitch cart and set tractor parking brakes. If ﬁlling unhitched, make sure that tongue jack is on an adequate surface. Chock cart tires.

2. Close quick-ﬁll shut-off valve at cart right.

3. Close cart outlet valve at cart rear.

4. Determine the desired application rate. Select and installed suggest drop-line oriﬁce plates (see

Seed and Fertilizer Rate Manual).

5. Close shut-off valve at pump.

6. If the strainer has not been serviced recently,

perform that maintenance before loading material (page 112).

7. Open both tank discharge valves , unless ﬁlling

only one tank at a time, in which case close the valve for the tank not being ﬁlled.

Calibration Crank, Bag and Scale

Refer to Figure 46

Under the right end of the walkboard, the drill includes a calibration crank , calibration bag, and digital scale. The bag and scale are stored in a compartment , held closed by the crank. A hook is provided for weighing.

The hand crank is provided for manual operation of the meters (the meters otherwise turn only when the drill is lowered and in motion). The crank is used for two common tasks:

• calibration of the meter setting for planting, and

• clean-out of the meter ﬂute chamber.

Calibration Crank Safety Information

Moving Chain Hazard: Keep all persons except operator away from drill mainframe during crank operations. Body parts and clothing can get caught in chains, sprockets and gears, causing serious injury. When operating the crank, all parts of the contact drive system are in motion, including parts out of sight of the operator.

Machine Damage / Invalid Results Risks: Rotate the hand crank only in the counter-clockwise direction. Operating in reverse can damage the meter gear box, and produces low sample sizes leading to incorrect calibration and excessively high ﬁeld rates.

Operating the Hand Crank

1. Turn on the seed monitor. This step is required if the Variable Rate option is installed.

2. Raise drill (page 41). This prevents the contact drive wheel from engaging the transport tire.

Note: Although the crank can be operated with the

contact drive engaged, it requires extra effort to override a ratchet coupling.

Refer to Figure 47 (note: Figure 47 exaggerates size of cranking directional decal)

3. Un-pin crank from storage location, and place over hex shaft at cranking location (right side of cart, between rear-most gearbox and transport wheel).

4. For meter clean-out, set both meters 80 or higher (LOW range), or 10 or higher (HIGH RANGE).

For calibration, set the ﬁnal Range gears, and the meter under test per the instructions in the Seed Rate Chart Manual, and remove a DRIVER or DRIVEN ﬁnal Range gear on the other meter.

Figure 46

Hand Crank in Storage

Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 57

Refer to Figure 48 (which depicts the meter without the gear guard - do not operate without the gear guard)

5. Lower the meter chute. Push the latch back (toward cart centre). Pull the outside end of the chute to the outside and down.

6. Open calibration door (front door, at air inlet side) on meter(s) being calibrated. See page 50 for door operations.

Material Loss Risk:

Open only the calibration door (front, meter air inlet side). Do not open the clean-out door (rear door, meter air outlet side) or material will ﬂow in large quantities. It is generally not possible to re-close the clean-out door, with sufﬁcient air seal, until the hopper is empty.

Refer to Figure 49

7. For calibration, remove calibration bag and

scale from storage compartment.

Note: The empty bag weighs 0.91 kg (2.00 pounds).

Refer to Figure 50

8. Hook bag to chute of meter under test. Place loops over ears at outside end of chute. Place hooks in chute latching slots.

9. Turn the crank until material is ﬂowing to the bag. Stop. Sweep any material in the chute into the bag. Empty the bag.

10. Turn the hand crank, counter-clockwise, to simulate meter operation for1⁄10ha or1⁄10ac.

Speciﬁc recommendations may be made in applicable manual sections. See: see “Meter Calibration” in the Seed Rate Chart manual, see “Unloading Materials” on page 113, and see “Storage” on page 67.

In general, you may operate the crank as fast as is comfortable. For reference, at a ﬁeld speed of 10 kph (6.2 mph), the jackshaft rotates at 90 rpm (11⁄2turns per second).

11. Sweep chute contents into bag.

12. Weigh sample: Attach scale to hook ( in Figure 46 on page 56). Zero scale. Attach bag to scale. Weight bag. Subtract bag weight from result.

13. Wipe the meter calibration door seal and ﬂanges. Close the calibration door.

14. Return scale and bag to storage compartment at task completion. Secure compartment door closed with calibration crank and pin.

1. Hydraulic Fan (page 60) The fan generates the air ﬂow required to deliver material to the rows. Speed is adjusted via the tractor circuit. Output is monitored via rpm , pressure gauge and pressure sensor .

5 8

2. Fan RPM Sensor (page 87) The seed monitor reports fan rpm based on this sensor. Although it is accurate for rate, it cannot detect a fan running in reverse.

3. Diverter Vane (page 89) This is present only on dual-hopper drills, and controls airﬂow balance between the meters. This may need adjustment with dissimilar material metering.

4. Manifold Pressure Gauge(s) (page 87) There is one gauge per hopper, mounted for ease of observation from the tractor cab. These report whether or not the air system is within recommended limits. On dual-hopper systems, the gauges assist in setting the diverter vane .

5. Meter Inlet Manifold (page 89) Fan air is divided (or further divided) into equal ﬂows for each meter inlet port .

6. Hopper (page 52) Material (seed or fertilizer) ﬂows into the top of the seed meter .

7. Pressure Balance Lines Each hopper contains an internal pressurebalancing system to equalize pressure above and at the base of the material.

8. Hopper Pressure Sensor This sensor signals the seed monitor, which can alarm if the hopper pressure goes out of limits. A dual hopper drill has two sensors.

9. Seed Meter The meter combines material with air ﬂow. It also has features for rate Range, calibration and clean-out.

10. Flute Shaft (page 168) Two (and optionally; three or four) sets of ﬂute “stars” control the ﬂow of seed from the hopper into the air streams.

11. Flute Shaft RPM Sensor (page 76) This shaft encoder provides metering rate data, stoppage alarms, and is used by the optional

Variable Rate Kit to control metering rate.

12. Meter Outlet Ports Material falls from the meter ﬂutes into the air

streams ﬂowing from inlet manifold to outlet ports. Each port is a separate compartment.

13. Single-Shoot Y-Tube A two-hopper drill may optionally have the output of both meters combined into a single stream to a single set of towers. The ﬂows combine at Y-tubes behind the meters.

14. Primary Seed Hose Four (single-hopper/shoot) or eight (double-shoot) hoses deliver seed from the meters to the towers .

15. Distribution Tower The riser tube and distribution rings have features to evenly divide the primary hose material ﬂow into multiple secondary hose ﬂows. There are four

towers on single-hopper and single-shoot drills, and eight towers on double-shoot drills.

16. Blockage Sensor Each tower outlet port has a sensor that detects material passage and signals the seed monitor. The primary function of this sensor is to trigger an alarm on ﬂow stoppage.

17. Secondary Seed Hose These hoses deliver material from a tower outlet port to a seed tube or fertilizer tube .

Fan Operation

Fan Safety Information

Rotating Fan Blade Hazard:

Do not operate the fan with guard screen removed. The fan accelerates instantly and with high torque. Body parts and clothing can be drawn into fan, resulting in death or serious injury. Disconnect fan circuit at hitch when working on fan.

High Pressure Fluid Hazard, Fan Hydraulic Motor:

Escaping ﬂuid under pressure can have sufﬁcient pressure to penetrate the skin causing serious injury. Use a piece of paper or cardboard, NOT BODY PARTS, to check for leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, seek immediate medical assistance from a physician familiar with this type of injury.

Machine Damage Risk: Protect Motor Seals:

Fan circuit has three hoses. All must be correctly connected. Make sure that “SUMP” line is connected to a tractor port capable of accepting high volume low pressure return oil. Connect Case Drain line to a low volume case drain return.

Avoid sudden circuit changes. Motor seals may be damaged by rapid starts and stops, or by circuit reversals. Engage fan circuit lever slowly, while observing fan rpm on seed monitor.

Note: Avoid fan direction reversal. A fan running in

reverse cannot generate sufﬁcient airﬂow for planting. If fan cannot reach target rpm, check for reversed circuit connections or improper drain connection.

NOTICE

Air leaks will cause erratic metering rates.

Bins should be periodically checked for air leakage.

(See operator’s manual.)

Fan General Information

The hydraulic fan supplies the air stream that carries materials from the meters, through the primary hoses to the towers, then to the secondary hoses to the rows.

The fan needs to be running in the correct direction, and within a narrow speed range, to reliably deliver material at your calibrated rates.

Machine Damage Risk:

Always engage the fan with the tractor at a low engine speed. Engaging the fan when the tractor is at high speed may cause fan damage.

Do not reverse hydraulic ﬂow with the fan running.

Fan Field Operation

1. Unfold the implement (page 35).

2. Set the Fan circuit lever to neutral.

3. With the tractor engine at low rpm, slowly Extend the lever for the Fan/Fold circuit. Bring the fan up to recommended speed (page 87). Let the fan warm up for 15 minutes before planting.

4. Lower the drill 1.5 - 3m (5 to 10ft) before planting is to begin. It takes a few seconds for seed to travel from the meters to the rows.

5. Leave the fan running during ﬁeld turns. Meter drive is shut off when the openers are raised.

6. At the end of application, raise openers. Stop material ﬂow before shutting off the fan.

7. Shut off the fan by carefully moving the Fan circuit lever to Float or Neutral. Avoid moving the lever into Retract. The fan does not stop instantly. A check valve in the fan circuit locally re-circulates oil until the blades coast to a stop.

Figure 53

31189

(Dual) Manifold Pressure Gauges

Note: If the fan plumbing or hitch hook-up is reversed, air

ﬂow rate will be very low or zero. If you are unable to reach 3000 rpm, check remote circuit mode and hose connections.

Note: Fan speed is monitored and reported by the seed

monitor, but is manually controlled. The optimum rate depends on the seed type and any treatments. “Fan Speed Suggestions” on page 87 for further information.

Note: On dual-hopper drills, operating pressure at the

meters is also affected by the diverter vane adjustment (page 89).

Marker Safety Information

Electrocution Hazard / Machine Damage Risk: Never fold implement with a marker extended. Never extend a marker with implement folded. Operate markers only with drill completely unfolded. A marker extended when folded is a major overhead electrocution hazard, overhead clearance hazard, and may damage drill systems.

31177

Sweep and Pinch/Crush Marker Hazards: Do not allow anyone to stand near or beyond the end of the wings during marker operations. A folding marker can cause serious or fatal crushing injuries. Marker disc is sharp. A folding or unfolding marker can cause serious lacerations and cause falls.

166-372M Table of Contents Index 2012-01-05

Marker Unfold and Fold

1. Clear the area within 4m (12ft) of marker arms on both sides of the drill.

2. Carefully move the circuit lever to extend and observe which marker side is extending.

Refer to Figure 54

3. If the marker extending is not on the desired side, reverse the lever (to retract) until the marker returns to the cradle . Set the control to Neutral brieﬂy,

then to Extend again. This cycles the sequence valve and extends the alternate marker.

4. When marker is fully extended, set circuit to Neutral.

5. To fold marker, set circuit to Retract until marker is in cradle.

6. To extend other side, Extend once more, as at step 3.

Special Dual-Marker Operations

Passes with same marker side:

• Retract (raise) the marker and make the turn.

• Begin to extend the opposite marker.

• Retract it, and extend the original marker.

Both markers unfolded:

• Fully extend one side.

• Momentarily Retract, then Extend to deploy opposite

side.

Note: Which marker side extends at circuit activation is

somewhat unpredictable, as it depends on the ﬁnal state of the sequence valve at last use.

Parking

Follow these steps when parking the drill for periods of less than 36 hours. For longer periods, see Storage, the next topic.

1. Position the drill on ﬁrm, level ground.

2. To reduce tongue weight, raise, fold and lock implement (page 39 and page 35).

Note: Static tongue weight of a loaded, lowered, and

unhitched drill can be as much as 1500 kg (3300 pounds).

3. Check that hopper lids are latched, and secure the hopper lids with security cable or padlock and chain to prevent entry by children. See “Lid Closing” on page 48.

4. Remove jack from storage position and pin securely to lifting stob on outside of drill tongue. See “Hitching Tractor to Drill” on page 26.

5. If ground is soft, place a wide block or plate under the jack to increase contact area.

6. Securely chock drill tires to prevent jack from digging or sliding off plate.

7. If drill is equipped with optional brakes, disconnect the lines at the hitch.

For dual line air brakes, disconnect the red (control) gladhand connector ﬁrst, at the tractor, then the blue supply connector, and store each connector in its matching colour-coded gladhand holder on the drill.

8. Un-hook electrical lines and protect with any plugs or caps provided.

9. Release pressure on hydraulic system, then disconnect hydraulic lines and pull all lines back onto drill tongue. Store hoses ends in keyholes of hose holder bracket. Largest hole is reserved for sump line.

10. Disconnect hydraulic brake line (option).

11. Disconnect the safety chain.

12. Unhitch from tractor or leading implement.

Setting Material Rates

Rate setting details are covered in the Seed Rate Chart Manual 167-085B, which also contains seed and fertilizer rate charts. The topic is covered only in summary form in the present manual.

The NTA607 or NTA2007 is a volumetric implement. For a given metering setup, rates vary for materials with different density and granularity. The charts provide a starting point, but calibration is essential for accurate application (even using both meters for the same material at the same rate). Material rates are set independently for each meter. The seed monitor reports, and can optionally control, seed and dry fertilizer rates.

Liquid fertilizer rates are set at the pump. The monitor console does not report or control liquid rates.

Check Contact Tires

Reliable material rates are only achieved if the ground drive system is working properly. The transport tires and contact drive tire must be the correct size, and must be inﬂated to factory speciﬁcations. Check tire pressures, particularly the contact tire pressure, whenever loading seed or fertilizer. See page 152. Always replace worn tires with the correct size.

Check Flute Shaft Type

For some unusual very high rate applications and some small seeds, Great Plains offers alternate meter ﬂute shafts (page 145) that change rates to 150%, 200% or ~25% vs. the factory standard shaft.

Refer to Figure 57 (which depicts a single ﬂute “star” with its halves, a single star mated, two stars staggered, and a ﬁller)

Know your “stars” setup. If your drill is unchanged from factory standard, you have standard meter ﬂute shafts with 2 “stars” (4 halves) per outlet. The number and type of “stars” determines the rate chart to use.

Refer to Figure 58 (depicting an inspection from below meter)

If the conﬁguration is not known, inspect the ﬂute shaft from the hopper lid (if hopper empty), or from below the meter, with the calibration door fully open. It is not necessary to remove the shaft. Inspect the ﬂutes

1 2 3

( or ), and ﬁller rings at active outlets.

On a standard “2 star” shaft, each seed drop outlet contains two standard ﬂute sets (4 halves ), each pair staggered slightly from the next. Unused outlets are fully blocked by ﬁller rings .

On a “3 star” shaft, each outlet contains 3 ﬂute sets. On a “4 star” shaft, each outlet contains 4 ﬂute sets, with no ﬁllers between adjacent drops. On a small seed shaft, each outlet contains one set of shallow ﬂutes .

See also “Changing Meter Flutes” on page 168.

Find Your Chart and Rate

Standard “2 star” rates are in the main section of the Seed Rate Chart Manual. “3 star”, “4 star” and Small Seeds rates are in the Appendix.

If you are planning to operate both hoppers, perform the setup steps separately for each hopper, as the conﬁgurations (including stars) may be completely different.

1. Conﬁrm that the chart is for the material and star conﬁguration you have.

2. Find your target population or application rate.

Note: If you have a choice of charts, for most consistent

results, pick one that results in a variable rate gearbox value between 30 and 70.

Dual Hopper Considerations

If you are applying the same material from both hoppers, what chart rate to start with depends on whether you will run both meters simultaneously, or sequentially (run one, then the other).

The charts do not account for “twin” hopper operation. If both hoppers are metering the same material, at the same rate, and at the same time, the output is twice the chart rate. If run sequentially, or metering different materials at the same time, treat them as single-hopper operation.

High Rate Flute Considerations

“High Rate” charts are provided for some seeds, but the charts do not cover all possible combinations of high-rate ﬂutes. You can use any standard-rate single-hopper chart.

Adjustment for Small Seeds

Small Seeds rates are provided for some seeds that might be compatible with the optional smaller/shallow ﬂute shaft. If the seed has a chart for the standard shaft, choose a chart rate that is about 500% (5x) the desired ﬁeld rate. The Small Seeds shaft meters at between 20% and 50% of the standard shaft.

Monitor Material Conﬁguration

The DICKEY-john®IntelliAG®monitor reads meter shaft speeds and can report kg/ha (or pounds/acre) planted.

The standard drill operates in GRAN SEED MONITOR and GRAN FERT MONITOR modes (described below).

With the optional Variable Rate Kit, the seed monitor can also control the variable rate gearboxes. With this kit, the GRAN SEED CONTROL mode is also available (described starting page 72).

In order to report/control accurately, the monitor requires several inputs. Inputs that rarely change were entered during drill setup. Inputs speciﬁc to particular materials (seed or fertilizer) need to be entered when those materials are ﬁrst used, and when changed.

Update Material Library

In order to correlate actuator output with desired seed rate (meter shaft rate), the system requires a Calibration Constant for each material to be used.

If you already had a material library, re-load it from an SD card or via the menus. Otherwise revise a default material name as the ﬁrst Control setup.

Create a Controlled Material

Re-deﬁne at least one material. Otherwise, create at least one material. Some key steps:

1. Type must be set to GRAN SEED CONTROL or GRAN FERT CONTROL.

2. Select or Disable: Preset Method

If using preset method, select initial rate increments that are only a few percent, so as to have ﬁne control of the meter scale indicator. These can be changed to coarser increments after calibration.

3. Density must be accurately entered.

4. #Outlets or #Towers is the number of outlets per meter, and is always “4” for NTA607/2007, whether single- or double-shoot.

5. Enter the Cal Const if one is available for your seed type. This value does not affect the calibration process, and is replaced during calibration, but is useful for comparison. The calibration constant developed during calibration should be similar to the seed rate chart number.

6. Set Variable Cal Const if one is available for your seed. This is from a list of names pre-programmed into the monitor software. It is usually not the same name as the material name setup on page 72. In this example, “Wheat 2S”, the “2S” refers to the (factory standard) “2 star” meter ﬂute conﬁguration.

Pick a seed constant closest to yours in terms of physical seed characteristics and meter ﬂute conﬁguration.

If a suitable Variable Cal Const is available, the system can more accurately compensate for manual calibration cranking speeds that differ from ﬁeld rate.

If no suitable Variable Cal Const is available, set to Disabled, and crank at an rpm near ﬁeld speed at step 36.

Meter Rate Adjustment

Seed rate is determined by:

• Flute shafts (covered on page 69): standard 2-star/1x rate, or optional 3-star/1.5x or 4-star/2x rates

• Single/twin hopper metering (covered on page 70).

• Seed meter Final Drive Range gearing

• Variable Rate Gearbox setting

The Seed Rate Chart Manual charts are based on cleaned untreated seed of average size and test weight. Many factors affect meter rates including foreign material, seed treatment, seed size, ﬁeld conditions, and test weight.

Minor adjustments will be needed to compensate for these factors. Initially set the rates according to the charts, then calibrate for your material and conditions.

Calibration is also required to set up the monitor Calibration Constant. With the correct Calibration Constant and material density the monitor can be used to help ﬁne tune the variable rate gearbox setting.

Seed Meter Final Drive Range

Refer to Figure 59 (which depicts the range gears with guard removed - do not operate without guards)

The meter ﬂute shaft is driven by the agitator shaft through a pair of interchangeable gears , . The positioning of these gears creates two ﬁnal drive ranges.

Each Seed Rate Chart is based on a speciﬁc Final Drive Range. The Ranges are:

• “High” range, which is used for larger seeds and higher seeding rates

• “Low” range, which is used for smaller seeds and lower seeding rates

The meter shafts are DRIVING” and “DRIVEN”. The “DRIVING” shaft is the upper (agitator) shaft. The “DRIVEN” shaft is the lower (ﬂute) shaft.

Refer to the Seed Rate Chart (or Fertilizer Rate chart), the table at right, and Figure 59 for setting the seed meter ﬁnal drive range.

1. Remove the nut and bolt ( , not visible) securing the

application rate sensor to the restraining straps at the meter sensor mount.

2. Loosen the thumbscrew .

3. Remove the pins from both shafts. Move the rpm

sensor clear of the ﬂute shaft.

4. Remove and position the gears as shown in the table

at right.

5. Secure the DRIVING gear on the agitator shaft with

a pin.

6. Secure the DRIVEN gear with the rpm sensor and a

pin.

7. Use the thumbscrew to eliminate any rotational play

in the sensor-to-shaft coupling.

8. Using the nut and bolt, secure the rpm sensor to the

restraining straps at the meter sensor mount.

To avoid operating a meter:

1. Remove a ﬁnal range gear and leave it off.

2. Set the variable rate gearbox to zero.

These steps are recommended even when the unused hopper is empty, to:

• reduce gearbox and meter wear

• during calibration, to avoid clogging air tubes at the meter not under test, and;

• avoid metering undesired material in the ﬁeld.

Setting Variable Rate Gearbox

Refer to Figure 60

The variable rate gearbox lets you inﬁnitely vary meter drive speed to attain a wide range of seeding rates. The ratio of gearbox input speed to output speed is controlled by the position of a gearbox control arm. The control arm has an indicator that points to a scale marked in degrees. The Seed Rate Charts and Fertilizer Rate charts show the rate for each degree of the control arm rotation.

• Manual: On the standard NTA607 and NTA2007 drill, the control arm is manually positioned with a crank . The initial setting is based on the seed rate chart, and reﬁned via calibration.

• Servo: With the optional Variable Rate Kit, the control arm is positioned by a linear actuator . The setting is commanded by the seed monitor, based on the rate entered on the seed monitor console, and the current Calibration Constant. The initial “Cal. Const.” is found in the seed rate charts, and reﬁned via calibration.

Manual Rate Setting

1. Consult the seed rate chart for your crop, ﬂute stars

and rate Range. Note the gearbox setting.

2. Remove the hairpin cotter securing the gearbox

adjustment crank.

3. Rotate crank until the control arm indicator points to

the scale setting that matches the rate from the seed rate chart or determined by calibration.

4. Re-insert the hairpin cotter.

Variable Rate (Servo) Rate Setting

1. Consult the seed rate chart for your crop, ﬂute stars

and rate Range. Note the “Cal. Const.”

2. Enter the seed rate chart Calibration Constant on the

seed monitor (for the Channel associated with the hopper and gearbox). If you have calibrated this seed, use the recorded Cal. Const. developed from that calibration.

3. Enter the desired material rate on the seed monitor

(for the Channel associated with the hopper and gearbox).

Figure 60

Variable Rate Gearboxes

Note: The variable rate gearbox operates optimally

between 30 and 70. If a seed has charts for both HIGH Range and LOW Range, the most consistent results are obtained when the gearbox control arm is set between 30 and 70. Settings below 20 degrees are not recommended. When the control arm is set above 70 degrees, large movements of the arm result in small changes in seeding rate.

Note: If you will be metering the same material from both

bins at the same time, use the Seed Rate Chart entry for half the desired application rate. Do not use a half scale setting - the effect of the variable rate gearbox control arm is not linear - a half scale setting is usually not half the rate.

Note: The hand crank is present on both manual drills,

and (servo) drills with the Variable Rate kit. On servo drills, the crank is disconnected from the control arm. To revert to manual control, move the coupler pin from the servo control arm to the manual control arm.

Meter Calibration

The Seed Rate Charts are based on cleaned untreated seed of average size and test weight. Many factors affect meter rates including foreign material, seed treatment, seed size, ﬁeld conditions, and test weight. The Dry Fertilizer Rate Chart is based on a representative granular fertilizer.

Great Plains recommends calibrating for the exact materials you intend to apply. Calibration determines two very important settings for achieving accurate rates:

• The kilograms per hectare (or pounds per acre) of the meter at the current variable rate gearbox setting for your particular seed or fertilizer.

• The Calibration Constant for the monitor to accurately report (or control) the planting rate of your particular seed or dry fertilizer.

The seed monitor must be setup for the drill, and if a variable rate kit is installed, there is additional setup for that. See: “Monitor Material Conﬁguration” on page 71.

The seed monitor must also be correctly set up for the material(s), or the calibration will not result in useful monitor displays, and may cause incorrect application rates if a variable rate kit is installed.

Calibration: Common First Steps

The calibration is different for manual (crank-adjusted) and servo (variable rate kit) gearboxes. These ﬁrst steps are common to both gearbox types.

The right column contains an example for the following steps.

1. Raise drill (page 41): This prevents the contact drive

wheel from engaging the transport tire.

2. Turn on the seed monitor.

3. Determine the Range and gearbox settings from the

rate charts.

4. If your material has a density that is signiﬁcantly

different from that used to generate the chart, you may want to adjust the density before choosing the initial gearbox setting and Range.

5. Set Range (page 76): Set the Final Drive Range gears per the seed rate chart or dry fertilizer chart.

6. Load material (page 51): Make sure there is enough material in the hopper(s) for at least1⁄10hectare (or

⁄10acre) plus an extra 35 to 45 kg (75 to 100 lbs.).

Refer to Figure 61

7. Since only one calibration bag (page 57) is provided, disable the meter that is NOT being tested, by removing one of the ﬁnal range gears .

8. Deploy meter chute (page 57).

9. Open the calibration door of the meter being calibrated (page 50). The calibration door is the bottom doors under the lower (ﬂute) shaft.

Material Loss Risk:

Do not open clean-out door (the door under the upper/agitator) shaft. Opening this door drains the hopper. Once this door is open it is difﬁcult to stop seed ﬂow until the hopper is empty, and it may be impossible to close with an adequate air seal.

Refer to Figure 62 (note: Figure exaggerates size of cranking directional decal)

10. Attach crank (page 56): Un-pin crank from storage location, and place over hex shaft at cranking location (right side of cart, between rear-most gearbox and transport wheel).

11. Weigh bag (page 57): Obtain the calibration sample bag and digital scale from the storage compartment. Zero the scale and weight the empty bag, or set “tare” using the empty bag. There is a hook for weighing at the left side of the right ladder mount (the ladder must be raised for convenient access).

Note: The empty bag weighs 0.91 kg (2.00 pounds) as

shipped from the factory.

12. Wipe all material off the ﬂanges around the meter door.

Refer to Figure 63

13. Hook bag to chute of meter under test. Place loops over ears at outside end of chute. Place hooks in chute latching slots.

For a manual gearbox, continue at step 14 on page 80.

Complete step 1 through step 13 beginning on page 78.

14. Set gearbox (page 77): Remove the hairpin cotter securing the gearbox adjustment crank. Rotate crank until the control arm indicator points to the scale setting that matches the rate from the Seed Rate Chart or as determined by any previous calibration of a similar material for the same rate.

15. Re-insert the hairpin cotter.

16. Turn the calibration crank, counter-clockwise, for enough turns to be sure the meter ﬂutes are full and the system is metering.

17. Stop cranking. Wipe meter doors. Sweep any material in the chute into the bag. Empty the bag.

18. Push and then and then to get to meter calibration.

19. On the seed monitor terminal,

set the monitor to Calibration mode .

enter [ 5 ] for the “# Meter Revs”, and

press the Start softkey .

This “# Meter Revs” parameter does not affect the monitor calibration because the monitor counts actual meter shaft revolutions and uses that count to compute the Calibration Constant.

Note: The rate of the arm adjusting crank is more than

one scale degree per turn, and the crank can only be pinned at quarter turns. Pin it when the indicator is closest to the desired setting.

Note: It is important to turn the calibration crank rapidly.

Use a comfortable speed of 1 to 13⁄4revolutions per second, which simulates a planting speed range of 6.7-11.8 kph (4.2-7.3 mph). A longer calibration is always more accurate, especially for low rates and small seeds.1⁄10hectare is easy to calculate with and is a minimum calibration run.

Note: For more accurate results,crank for a full hectare or

21. Wipe all the material off the ﬂanges around the meter doors, on the chute, and capture that material in the calibration bag.

22. Accurately weigh the calibration bag plus material. If you set a “tare” on the scale, the reading is the

Manual Seeding Example; Net Weight (step 23):

TotalWeight is 20.96 kg for bag plus sample BagWeight is 0.91 kg

24. Press the Stop softkey on the monitor and enter the sample net weight (SampleWeight). The monitor responds with a Calibration Constant.

Push the Save softkey to accept this value.

25. If the sample was based on1⁄10hectare (or

⁄10acre), multiply the sample size by 10 to

determine application rate per acre (hectare) at the current variable rate gearbox setting.

CalibratedRate SampleWeight 10×=

If the calibrated rate matches the target rate, skip to step 31. Otherwise…

26. Subtract the calibrated rate per hectare (or acre) from the target rate to determine a correction difference.

RateDifference T etRarg ate CalibratedRate–=

If the calibrated rate turns out to match the desired target rate, record the material details and ﬁnal Calibration Constant for future reference.

Manual Seeding Example; Calibrated Rate:

CalibratedRate = 20.96 x 10, which is:

209.6 kg/ha

This is 4.8% higher than our target rate of 200 kg/ha. However, because the gearbox actuator effect is not linear, we cannot simply adjust the control arm by 4.8%.

Metric Example: TargetRate =

200

RateDifference =

200 - 217,

which is:

-17 kg

USc Example: TargetRate =

67.6

RateDifference =

which is:

The calibration run metered too much. You must lower the gearbox setting to compensate.

27. Refer to the Seed Rate Chart for gearbox setting values for the target rate.

28. Determine the amount of rate change for each degree of control arm rotation from the target setting.

If the calibrated rate was higher than target (as in our example), examine lower gearbox setting values.

If the calibrated rate was lower than target, examine higher gearbox setting values.

29. Adjust the control arm by the number of degrees needed to adjust for the calibration difference.

The rate of the arm adjusting crank is more than one scale degree per turn, and the crank can only be pinned at quarter turns. Pin it when the indicator is closest to the corrected setting.

30. To validate the adjustment, run the calibration again, starting at step 14 on page 80, using the new Variable Rate Gearbox scale setting.

This validates the gearbox adjustment, and will generate a new, more precise Calibration Constant.

31. With the present meter satisfactorily calibrated, remount the ﬁnal drive gear removed (if any) from the meter on the other hopper.

32. Repeat the calibration procedure for the other hopper, starting at step 1 on page 78.

33. Continue at “Calibration Close-Out” on page 84.

Variable Rate (Servo) Calibration

Note: For drills with manual (crank set) gearboxes, use

the instructions at “Calibration for Manual Gearbox” on page 80.

Complete step 1 through step 13 beginning on page 78, and “ACC Re-Conﬁguration” from the Variable Rate Kit manual 166-263M. You must have created or selected a Material that matches the material you are about to calibrate.

34. Check that ﬁnal Range gear pairing is the same on:

• the seed rate chart,

• the meter, and

• the Meter gear Range in the Channel Setup.

35. Enter the calibration screen for the Channel assigned to the meter to be calibrated.

At this time, the linear actuator for that meter’s gearbox becomes active. The scale indicator moves to approximately mid-scale, then stops.

Pointing to a speciﬁc value is not required, but it needs to be in the range 30° to 95°. Great Plains recommends using a scale setting that is close to your expected target rate.

Use the Inc+/Dec- softkeys on the monitor console to adjust the indicator to the seed rate chart Gearbox Setting value, or at least to within the 30°-95° range.

Planting Depth Adjustments

Planting depth is affected by several adjustments, summarized here:

Refer to Figure 64

1. Soil Conditions: Changes in ﬁeld conditions can require changes to several of the adjustments below.

2. Row Unit Opener Depth: (page 98) The T-handle directly controls opener depth by setting the press wheel height.

3. Tool Bar Height: (page 86) Spacers at the centre section (master) lift cylinders control the centre section tool bar height when the implement is lowered.

Wings must also be level (page 133) for this adjustment to accurately set wing gauge wheel height.

In more challenging conditions, increased cart weight transfer (page 90) may be required to prevent openers from lifting tool bar.

4. Wing Weight Transfer: (page 90) If the wings are not operating at desired planting depth, more centre section weight may need to be transferred to wings.

5. Coulter Depth: (option, page 92) Optional coulters prepare the furrow ahead of the openers. If coulters are running too shallow or too deep, the openers may not operate at the desired depth.

6. Row Unit Spring Adjustment: (page 95) Several rows (in tire tracks) may need to be set to higher down-force in challenging conditions.

7. Opener Wear: (page 95) Over time, opener disc wear can cause established T-handle settings to become too shallow.

Adjusting Tool Bar Height

Refer to Figure 65

See “Heights and Levelling” on page 32 for how to check tool bar height. To change the tool bar height, add or remove master lift cylinder rod spacers , in the combinations shown in the chart at the bottom of this page.

To change spacers:

1. Perform a Lift operation (page 40).

2. Add or remove spacers. Unused spacers are stored on rods loops welded to the cart-implement link (not visible in ﬁgure). If you store spacers on hoses, make sure they cannot slide into locations where they interfere with implement operation.

Note: Chart values are approximate. Press wheel

settings, disc wear and manufacturing tolerances can cause actual heights and depths to vary from chart values. Choose spacer combinations based on actual ﬁeld measurements.

Note: The cylinder has 5.7cm (21⁄4in) of exposed rod

when fully retracted, for a minimum tool bar height of 58.4cm (23.0in). All spacer combinations that increase tool bar height above the minimum must be a stack of at least 5.7cm in height.

Note: Each full (1) cm or (1) inch of spacer stack height

change changes the tool bar height by 2cm or 2in.

Note: Do not use a spacer stack taller than

10.2cm (4.0in), or the furrow will be too shallow, or there will be no furrow at all.

Air System Adjustments

There are two adjustments for the air system:

1. Fan rpm (this page), which controls manifold air pressure, hopper air pressure, and material delivery velocity.

2. Inlet Manifold Diverter angle (page 89), which controls the balance of air ﬂow to each meter on dual-hopper drills (whether single- or doubleshoot). This adjustment is not present on singlehopper drills.

There is no direct adjustment for hopper pressure. The table ﬁgures are included for setting alarm limits in the seed monitor. If a pressure alarm occurs, do not adjust the fan or diverter to compensate. The cause is usually a leak or a major blockage.

Fan Speed Suggestions

The speciﬁc fan rpm required varies considerably with drill conﬁguration, material density, application rate, ﬁeld speed and material properties. Develop and record settings that are suitable for your operations.

Machine Damage Risk:

Always engage the fan with the tractor at a low engine speed. Engaging the fan when the tractor is at high speed may cause fan damage. Do not reverse hydraulic ﬂow with the fan

running.

At ideal fan speed:

• ﬂow is more than high enough to avoid blockages

(from both meters on dual-hopper drills),

• ﬂow is even across all hoses from each meter; and,

• ﬂow is low enough to minimize seed cracking and

bounce.

Fan speed is monitored and reported by the seed monitor, but is manually controlled.

If the fan cannot reach 3000 rpm, one or more hoses may be mis-connected. Air moves toward the air box in either rotation direction, but reverse spinning airﬂow is too low to operate the system.

If the fan is operating properly, and at desired rpms, and the diverter is correctly adjusted, but the pressure gauge is out of limits, see “Magnehelic® Gauge

Troubleshooting” on page 108.

Adjusting Fan Speed

Start with the rpm settings in the table on page 87. Adjust for your situation.

Start with ﬂow on low setting. 30-45 litres/min (8-12 gpm) is average ﬂow.

Run fan for at least 15 minutes before seeding. Hydraulic ﬂuid must be warm before fan and wing pressure systems operate properly.

1. Check bin-lid and meter-box seals for air leaks. Adjust the latch or replace the seals to prevent leakage.

Note: It only takes a very small air leak to cause large

variations in the seeding rate and pattern.

2. Watch the manifold pressure gauge(s) and seed monitor, and adjust fan speed by increasing or decreasing hydraulic ﬂow from the tractor. Use the guidelines and the fan speed chart on page 87 to properly adjust fan speed.

Fan Speed Tips

• Higher fan speeds improve seed distribution, but high fan speeds also increase the chance of seed damage and bounce.

• At ﬁrst, adjust fan speed to the high end of the range suggested in the chart on page 87. Watch for excessive seed cracking and seed bounce from the furrow, then reduce fan speed if necessary.

• Follow the chart at right as a guide. Actual fan speeds vary with implement width, row spacing, seeding rates, seed weights and seed size. Increase fan speed for heavier seeding rates or seed. Reduce fan speed for lighter seeding rates and seed more prone to cracking.

Diverter Vane Adjustments

Refer to Figure 67 (and Figure 51 on page 58)

On dual-hopper drills, where the material in each hopper differs, the meters may require substantially different air ﬂows. Dual pressure gauges, and a diverter vane are provided for setting unequal ﬂows.

An example of a situation likely to need unequal ﬂow is:

small light seeds in hopper I, and

dense dry fertilizer in hopper II. The need for unequal ﬂows may be observed only during actual ﬁeld operation, as material must be entering the airﬂow and generating air demand.

Diverter Operation

The vane (not shown) inside manifold is attached to a rod with a handle on the bottom end, and a nut (not

shown) at the other end of the rod on top of the manifold.

The factory setting for the handle is pointing straight forward, providing balanced ﬂow to each meter. Decals, on manifold top and bottom, show the approximate angle of maximum effect.

To adjust the vane:

• Loosen the top nut.

• Turn the handle to point

toward the side where reduced ﬂow is desired, and away from the side where increased ﬂow is desired.

• Tighten the top nut.

Diverter Tuning Steps

1. Start with:

• moderate fan speeds (see page 87)

• balanced manifold air ﬂow - set/leave the diverter vane handle straight forward.

2. Begin ﬁeld operations. Watch for delivery issues that might be remedied by an uneven ﬂow, such as blockage, pressure alarms and seed cracking/bounce.

3. Adjust fan rpm up and down until you discover the upper and lower rpms that represent the optimal working range for each meter. Note the upper and lower the manifold pressures for that operating range. The ideal (median) pressures for each meter are likely to be different.

4. If there is no single fan speed that puts both meters comfortably within their ideal operating range, set the fan to an averaged median rpm, and begin adjusting the diverter vane. The goal is to bring both pressure gauges to levels within their optimal range similar to those determined at step 3.

5. After the ﬁnal vane setting is made, some fan rpm adjustment may be needed to bring both gauges to the median readings in the optimal range.

Figure 67

Diverter Vane Location

Note: Vane is not present on single-hopper drills.

Note: If applying a single material on a single-shoot drill,

Great Plains recommends loading the material into both hoppers and using half rate (see Seed Rate Chart Manual for details). Set vane for equal pressures to each meter.

Note: If applying a single material on a double-shoot drill,

use a single hopper. Set the vane to divert the maximum ﬂow to the used side (this does not completely shut off air ﬂow to the unused hopper, which needs some airﬂow to avoid nuisance

Weight Transfer Adjustments

Weight Transfer Safety Information

Crushing Hazards: This adjustment requires working near the unfolded and lowered drill with the hydraulic system active. Assign two people to this task, one in the tractor cab, ready to shut the tractor down on hand signal from adjuster or any unplanned event. Keep body parts clear of wings and openers while adjusting. Keep all bystanders well away. You will be seriously injured or killed if you are caught between lowering openers and ground, or raising openers and drill frame.

High Pressure Fluid Hazard:

Escaping ﬂuid under pressure can penetrate the skin causing serious injury. Use a piece of paper or cardboard, NOT BODY PARTS, to check for suspected leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, seek immediate medical attention from a physician familiar with this type of injury.

Falling Hazard - Tires Not a Step:

Do not use tires as steps or platforms. At higher transfers, cylinders can lift cart wheels sufﬁciently for them to spin.

Refer to Figure 69 on page 91

During ﬁeld operations, the Fold cylinders distribute centre section weight to the wings. The wings are much lighter than the centre section, and some weight needs to be transferred. The wing-transfer valve controls the

amount of weight transferred.

The wing transfer valve needs an initial setting and

possible later adjustment. If insufﬁcient weight is transferred, the wings run higher than the centre section. If excess weight is transferred, the centre runs higher.

The centre section lift lock and cart-transfer functions share a hydraulic circuit. There needs to be some circuit pressure for a pilot-operated check valve to switch between functions. Also, at higher row unit down-forces, there may be insufﬁcient total implement weight. A pair of cylinders between the cart and implement allow some of the cart weight to be transferred to the implement. The cart-transfer valve controls the transfer.

The cart transfer valve may often be left at the nominal 100 psi value.

Material Rate Risk:

The cart transfer cylinders can un-weight the cart sufﬁciently to cause ground drive slippage, and in extreme cases, actually lift the cart wheels off the ground.

Note: To avoid planting problems, do not exceed

1500 psi for wing-transfer, and 1000 psi for carttransfer. A relief valve prevents operating the wingtransfer at over 1500 psi.

Material Rate Risk:

Do not set cart weight transfer higher than necessary. Values close 1000 psi can lift the rear of an empty cart off the ground. As a cart nears empty, the main tires can begin to slip, or stop turning altogether, resulting in irregular seeding rates or stoppages.

Frame-Mounted Coulters

Frame-mounted coulters are used “in row” and not “zone”. They are intended to prepare the soil directly ahead of the seed furrow.

The factory suggested default setting, with new coulter blades, at:

3.8cm (11⁄2in) opener (planting) depth ,

is a coulter depth of:

5.1cm (2in), or 13mm (1⁄2in) below opener depth.

Frame-Mounted Coulter Adjustments

There are several frame-mounted coulter adjustments:

Refer to Figure 70

1. Frame (tool bar) height: Frame height directly controls group coulter

depth .

If the centre frame is not running at the correct height, coulter depth is also incorrect. See “Adjusting Tool Bar Height” on page 86.

Figure 70

07 Coulter and Row Unit

31196

Wing frame height is controlled by centre frame height, and is affected by wing weight transfer. See “Wing Weight Transfer Adjustment” on page 91.

Refer to Figure 71

2. Individual row unit height: A few individual rows may be lowered by loosening

6 7

nuts at tool bar U-bolts, sliding the spring bar down and re-tightening. Do not lower more than about 2.5cm (1in) Keep the top edge of the spring bar at or above the top of the upper bolt holes.

3. Individual coulter down-force (page 93): This is a spring adjustment for rows in tracks, or all rows - in unusually light or heavy no-till conditions.

4. Coulter-to-row alignment: Coulters are factory aligned so that the coulter disc prepares the furrow directly ahead of the opener discs.

After any coulter or row maintenance, check that these components are still aligned. Adjust at the coulter mounting clamp at the tool bar. Re-check coulter height if any adjustments are made.

In regular or heavy no-till conditions, adjust opener depth to set:

the coulter depth to about 13mm (1⁄2in) deeper than

seeding depth.

In addition to checking depths at setup, be sure to check actual seeding results while planting.

Replace the 432mm (17in) coulter blades when their diameter is worn to less than 400mm (153⁄4in).

Frame-Mounted Coulter Force

In normal operation at target running depth, the spring is at full extension or only slightly compressed. It compresses brieﬂy as obstructions and denser soil are encountered.

Coulter springs are set to 181 kg (400 lbs). In normal operation at target running depth, the spring is at full extension. It compresses brieﬂy as obstructions are encountered.

• In heavy no-till conditions, you may observe the springs in compression most of the time. This means that the blades are not reaching the desired coulter depth. If drill weight is available, you can increase the spring down-force to compensate.

• In light but rocky conditions, the factory spring setting may be higher than needed. You can extend blade life by reducing the force at which the blades ride up over obstructions.

To adjust the coulter spring:

Refer to Figure 72

1. Unfold implement. Conﬁgure implement for

maintenance lift lock (page 110).

2. Determine the new spring length desired. See the

table at right.

3. Measure the current length of the spring(s) to be

changed. If already shorter than 248mm (93⁄4in), or longer than 260mm (101⁄4in), do not further adjust them.

4. Loosen the jam nut .

5. Rotate the adjuster nut until the spring is at the

new length. Tighten the jam nut.

Note: If all springs are continuously in compression, the

coulters can lift the wing frames off the ground (at the gauge wheels), resulting in uneven coulter depth and/or uneven seed depth. If the drill is already operating at maximum down-pressure, reduce coulter depth.

Spring Length Force at Blade

26.0 cm (10.25in) 136 kg (300 lbs.)

25.4 cm (10.0in) 181 kg (400 lbs.)

24.8 cm (9.75in) 238 kg (525 lbs.)

Machine Damage Risk:

Do not use spring lengths shorter than 248 mm (9.75 in). It may contribute to premature parts failure not covered by warranty.

07 Series Row Unit Adjustments

Refer to Figure 73 (which depicts a row unit fully populated with all optional accessories supported for use with the NTA607 or NTA2007)

From front to back, a Great Plains 07 Series row unit can include the following capabilities (some optional):

1. Frame-Mount Coulter: optional See “Frame-Mounted Coulter Adjustments” on page 92.

2. Down Pressure Spring: standard Each row unit is mounted on the implement via arms which allow the row unit to independently move up and down. The adjustable spring sets the force at which the opener rides up over obstructions. See “Row Unit Spring Adjustment” on page 95.

3. Disc Blades: standard, 2 per row unit Double disc blades open a furrow, creating the seed bed. Spacers adjust the blades for a clean furrow. See “Disc Blade Adjustments” on page 95.

4. Seed delivery tube: standard This tube delivers material from hopper I on singlehopper or double-shoot drills. It delivers material from both hopper I and hopper II on single-shoot drills. No adjustments are necessary.

5. Inside Scraper: optional Helps prevent clogging between disc blades. See “Disc Scraper Adjustments” on page 96.

6. Liquid Fertilizer Tube: optional This is present only if both a liquid fertilizer system and Keeton® seed ﬁrmers are installed. It requires no adjustment.

7. Seed ﬁrmer: seed ﬂap (not shown) standard: A seed ﬂap requires no adjustment, other than replacement (page 135) when worn.

Keeton® seed ﬁrmer (shown) Improves seed-soil contact, and provides a stable arm for a low-rate liquid fertilizer delivery tube. See “Keeton® Seed Firmer Adjustment” on page 97.

Machine Damage Risk:

Do not back up with row units in the ground. To do so causes severe damage and row unit plugging.

8. Dry Fertilizer Tube: optional This tube delivers material from hopper II on doubleshoot drills. The delivery angle is adjustable (page 98).

9. Press wheels: standard (choice of types) These close the seed trench.

The press wheels also support the free end of the row unit, and provide the primary control over seeding depth via the T-handle. See “Opener Depth (Press Wheel Height)” on page 98.

Row Unit Spring Adjustment

Row unit springs normally require no adjustment. The factory setting for the row unit springs is:

Spring length 324 mm (12

Assembly length 562 mm (221⁄8in)

⁄4in)

In some unusual conditions, rows in tire tracks may need to be set heavier.

1. Make adjustments with the wings unfolded and the rows lifted off the ground, so that the springs are at full extension.

2. Loosen the jam nut . Rotate the adjuster nut .

3 4

Shorten spring to increase down-force; lengthen spring to reduce down-force.

Figure 74

Row Unit Spring

29427

For each turn of the adjuster nut, the down force at the opener disc changes by approximately:

1.7 kg/turn (3.7 lbs/turn)

3. Re-tighten jam nut after setting force.

Disc Blade Adjustments

Opener disc angle and stagger is not adjustable, but disc-to-disc spacing is, and may need attention as discs experience normal wear. Spacers will need to be reset when blades are replaced.

Refer to Figure 75

The ideal spacing causes the blades to be in contact for about 25 mm (1 inch). If you insert two pieces of paper between the blades, the gap between them should be 0 to 44 mm (0 to 1.75in).

If the contact region is signiﬁcantly larger or smaller (or there is no contact at all), it needs to be adjusted by moving one or more spacer washers. If the contact region varies with blade rotation, one or both blades is likely bent and in need of replacement.

Machine Damage Risk:

Do not use spring lengths shorter than 29.8 cm (113⁄4in). It may contribute to premature parts failure not covered by warranty.

Adjusting Disc Contact

Sharp Object Hazard:

Use caution when making adjustments in this area. Row unit disc blades may be sharp.

Refer to Figure 76

1. Unfold implement. Conﬁgure implement for maintenance lift lock (page 110).

2. Remove the bolt retaining the opener disc on one side. Carefully remove the blade , noting how many spacers are outside the disc and how many are inside the disc. Do not lose the hub components and spacers.

3. To reduce the spacing between the discs (the normal case), move one spacer washer from the inside to the outside.

Note: When installing new blades, it is generally

necessary to move outside spacers back inside after both discs are mounted.

4. Re-assemble and check disc contact.

Disc Scraper Adjustments

Slotted disc scrapers are standard. Spring-loaded carbide disc scrapers are optional. See page 148 ordering information and page 169 for installation. To keep opener discs turning freely, dirt scrapers are mounted between discs to clean as discs rotate.

Sharp Object Hazard:

Use caution when making adjustments in this area. Row unit disc blades may be sharp.

Refer to Figure 77

As ﬁeld conditions vary, scrapers may need to be adjusted. In damp conditions, lower scrapers. If openers are not turning freely, raise scrapers. To adjust, loosen bolt and move scraper as needed.
