Introduction

Great Plains welcomes you to its growing family of new product owners. Your 9m/30ft 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 25. Have all operators read this manual before allowing them to work with the machine.

Description of Unit

The NTA907 or NTA3007 is a pull-type integrated air drill seeder. The implement folds for narrow 3 m (9 ft. 81⁄2in.) 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 dual 3500 litre (100 bu) hoppers for separate or simultaneous delivery of seed and/or granulated dry fertilizer. Each hopper has an independent metering system with user-preset inﬁnite ratio gearboxes. Console-controlled variable rate meter servos are optional.

The NTA907 or NTA3007 has double-disc Series 07 openers, suitable for conventional till and, minimum-till conditions. With optional coulters, the air drill is suitable for moderate no-till conditions.

Brakes are standard on model NTA907 and optional on model NTA3007. 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 auger, ﬁeld markers, tramline kits, high rate ﬂutes, and alternate discs, scrapers and 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.

NTA907 or NTA3007 Drill

Intended Usage

Use the NTA907 or NTA3007 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 “WarningSafety Reﬂectors and

Decals” on page 11, thoroughly.

▲ Read all instructions noted on the decals.

▲ Keep decals clean. Replace damaged, faded and illegible

decals.

a. Symbols and safety colours in this manual, and on machine model NTA3007, are based on ANSI standard Z535.

Pictogram symbols and colours on model NTA907 are based on ISO standard 3864.

b. Pictograms (language-free safety decals), found on models NTA907, are generally on a Safety Yellow background regardless of

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

2012-07-02 Table of Contents Index 166-371M

6 NTA907 or NTA3007 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.

166-371M Table of Contents Index 2012-07-02

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 NTA907 or

NTA3007.

▲ 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, a hopper may become “permit-required conﬁned space” under applicable statutes, regulations, insurance rules or business policy. The vent tube structure in the hopper 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 126.

8 NTA907 or NTA3007 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.

Remain Clear of Overhead Lines

▲ If the drill contacts a power line, lethal voltage may be

present on all metal parts. At higher voltage, the drill does not need to be in line contact for the hazard to exist. Maintain at least 3 m (10 foot) clearance.

▲ Electrocution can occur without direct contact between the

energized drill and a person near the drill.

▲ Watch for sagging, damaged or low electrical lines. The

auger could contact lines lower than 5.3 m (17.5 feet). Overhead lines at farm structures are a particular hazard. An auger is at risk from lines lower than 9 m (28 feet).

▲ Watch for all electrical lines during folding, unfolding,

marker and most especially auger operations. Use a spotter during these operations. Know the location and height of all lines during loading, transport and in ﬁelds.

▲ If an electrical hazard is observed while on the ground near

the applicator, hop at least 30 m (100 feet) away with both feet together and summon professional help. At higher voltage, lethal voltage gradients can also be present at the soil surface.

▲ Consult your tractor manual for advice on how to respond

to an electrical hazard event while in the cab.

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 9

Transport Machinery Safely

Maximum transport speed for implement is 30 km/h 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 km/h or 20 mph. Never travel at a speed

which does not allow adequate control of steering and stopping. Reduce speed if towed load 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 163.

▲ 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.

Practice Safe Maintenance

▲ Understand procedure before doing work. Use proper

tools and equipment. Refer to this manual. For brake work, see speciﬁc safety information beginning on page 138.

▲ 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 grounding cable (-) before servicing or

adjusting electrical systems.

▲ Welding: Disconnect battery grounding. Protect hydraulic

lines. Avoid fumes from heated paint.

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

and installed properly.

▲ Remove buildup of grease, oil or debris.

▲ Remove all tools and unused parts from drill before

operation.

Preparation and Setup

This section helps you prepare your tractor and NTA907 or NTA3007 for use, and covers seasonal tasks, and task when the tractor/drill conﬁguration changes.

Before using the NTA907 or NTA3007 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 183 and “Appendix C - Option Installation” on page 185 for pre-delivery items (normally completed by dealer), and ﬁrst-time/infrequent setup tasks, including:

❑ Install seed monitor console in tractor (page 183).

❑ Remove protective ﬁlm from large highway

reﬂectors.

❑ Set marker extension (page 183) 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 128).

❑ Wing levelling and alignment (page 145).

❑ 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”, pages 5 through 10.

❑ 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 148.

❑ Check that all safety decals and reﬂectors are

correctly located and legible. Replace if damaged. See “Safety Decals” on page 11.

❑ Inﬂate tires to pressure recommended and tighten

wheel bolts as speciﬁed. See “Tire Inﬂation Chart” on page 166.

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. Move the tractor to near hitching position.

2. Put the tractor in Park. Set the tractor’s parking brake. Shut down the tractor.

Refer to Figure 5 (which depicts the parking jack removed, but not yet stored)

3. Adjust the NTA907 or NTA3007 hitch to match your tractor draw bar height, using crank of tongue jack on side of tongue.

Note: The precise height is not critical, as the NTA907 or

NTA3007 levelling is set at the mainframe and is independent of tongue level.

Figure 5

Drill Hitched

29522

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. A hitch failure could result in a serious accident and is likely to result in implement and/or tractor damage.

4. Securely attach the safety chain to an anchor on a tractor capable of pulling the NTA907 or NTA3007.

Refer to Figure 5 and Figure 6

5. Use crank to raise parking jack foot . Remove

pin and jack.

6. Move jack to upper stob . Rotate to horizontal. Re-pin.

Equipment Damage Risk:

Store the parking jack on the upper stob in a horizontal orientation, foot to rear. Using the lower stob, or any other orientation, will result in jack and tongue damage.

7. Connect hydraulic hoses (page 28).

8. Connect brake hoses (option, page 29).

9. Connect electrical cables (page 30).

10. Remove and store main tongue parking stand.

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 bands.

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

The lift/down-pressure hose (blue) must be connected to a circuit capable of continuous pressure.

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 “Console Installation” on page 183 prior to ﬁrst hitching.

Protecting Fan Hydraulic Motor Seals

Low Pressure (Case) Drain Connection:

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

2. Connect low pressure motor return hose, marked “SUMP”, to a high volume low pressure return port. The sump line is distinguished by a large

2.7 cm (1.06 inch) diameter) quick coupler.

3. Connect hydraulic hoses to tractor remotes.

166-371M Table of Contents Index 2012-07-02

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 (1⁄4inch) I.D. hose and small, ﬂat-face, low-seep connector. DO NOT connect the case drain line to a power-beyond port.

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.

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

Brake Hook-Up (Option)

Two drill braking (trailer braking) systems are available:

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

• Single-line hydraulic system (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.

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

Braking Hazards: Make sure the operator understands when drill brakes are engaged and when they are released (record tractor behaviour on page 52).

Also understand and implement 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 (Option)

Refer to Figure 10

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

Refer to Figure 11

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

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

Figure 8

30 NTA907 or NTA3007 Table of Contents Index Great Plains Manufacturing, Inc.

4. 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 NTA907 or NTA3007 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 (Option)

Refer to Figure 12

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

The factory default connector is a3⁄4inch poppet-style 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:

⁄4inch male ORB (O-Ring Boss), or

⁄4inch female JIC (Joint Industry Conference, 37°

ﬂare).

• DO NOT DRIVE OVER WHEEL CHOCKS

1. 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 most safety when installed ahead and behind the outside front transport tires.

When not in use, the chocks are stored in holders mounted on the side frames. The chocks are held in place by gravity when correctly stowed in the holders.

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

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.

Checking Drill Height

The drill is designed to operate with all sections of the main tool bar nominally 76.2 cm (30 inch) above the planting surface. The height of the centre section is not routinely adjustable. Set planting depth with row unit adjustments.

When lowering the drill for the ﬁrst time on the planting ground:

1. Completely lower the main tool bar. If necessary, ﬁrst lift off transport locks, remove and stow locks.

2. Set hitch to planting height.

3. Pull forward a meter or so (a few feet).

Note: Level frame in planting conditions.

Failure to do so may result in implement not producing desired results.

49.5 cm (19.5 in)

Figure 17

Initial Tongue Height

Mis-Adjustment Risk:

Drill must be fully lowered to ﬁeld position (with openers into ground) and hitch height must be set before making side-to-side adjustments.

Refer to Figure 18

4. Check tool bar height across drill. See page 145 for further detail and adjustment.

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 NTA907 or NTA3007 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 148.

❑ Check all tires for proper inﬂation. See “Tire

Inﬂation Chart” on page 166.

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

shown in “Torque Values Chart” on page 167.

❑ 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.

CFM Overview

The Control Function Module (CFM) is located below the DICKEY-john® console terminal. The CFM controls a bank of solenoid valves on the drill, in the Fold/Tilt/Marker circuit.

On/Up opens the solenoid valve for the function. Off/Down closes the solenoid valve for the function.

Control Function Module

Unfolding the Drill

Unfolding Safety Information

Roll-Away Hazard:

Unfold only on hard level ground. Allow ample room. Drill, tractor, or both must be free to move during unfolding. On a slope, roll away could occur, causing an accident resulting in death, serious injury and substantial property damage.

Electrocution Hazard:

Keep clear of overhead power lines when unfolding, operating, folding or transporting the drill. Machine is not grounded. 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 unfolding. The distance between the tractor and the seed structure decreases by 3.2 m (7.5 feet) during unfolding. Drill, tractor, or both will move during this operation. Wings will tilt down and swing out. Risks include:

▲ Pinching or crushing at pivot points and at multiple sites in

pivoting assemblies. Stay clear of the wing sweep arcs. Coulters and row openers are sharp.

▲ Crushing under lowering/moving wing wheels, under

moving transport wheels, under lowering wings or under lowering openers.

Falling Hazard - Tires Not a Step:

Do not use tires as steps or platforms. Wing gauge wheel tires are off the ground in transport lift. Front and rear main transport tires may be lifted and free to spin on unlevel ground and at some weight-transfer and row down-force settings.

CRUSHING HAZARD

To avoid serious injury or death from crushing:

Machine moves rearward when foldng wings forward.

Stay away from machine while folding and unfolding

848-841C

General Cautions:

▲ Unfold only with markers resting in transport cradles.

Do not unfold with openers lowered, or machine damage will result.

▲ Unfold only if hydraulics are bled free of air and fully

charged with hydraulic oil.

Lowering and Raising Drill

Lowering/Raising Safety Information

Crushing Hazard During Lowering:

Stay clear of wings and openers during raising and lowering. Opener sections, in addition to being extremely heavy, are forced down with hydraulic pressure. Coulter and opener discs are sharp. During lowering, openers will cut or crush anything beneath them, and can cause death or serious injury.

Crushing Hazard While Raised:

Fully lower openers when working above or beside them. Use blocking or stands when working under openers. Raised wing openers are held up only by hydraulic pressure. With wings tilted down, openers will slowly lower over time. They may lower more rapidly if the hydraulic system is damaged. They will lower rapidly if the hydraulics fail, or if the lift circuit is set to Float or Retract.

Ground Contact Risk:

Do not lower openers while any drill folding operations are under way or partially complete.

Note: The lift (raise/lower) circuit is also the hydraulic

down-pressure circuit. Hydraulic down-pressure only functions as intended if the transport locks are set to FIELD (page 39).

Lowering

1. Unfold drill before lowering (page 34).

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

3. Actuate dedicated lift circuit (normally Extend).

4. If down-pressure has been adjusted (page 101), leave the circuit in Extend.

If down-pressure has not been adjusted, or if not planting immediately, set the circuit to Neutral.

Folding Safety Information

Roll-Away Hazard:

Fold only on hard level ground. Allow ample room. Drill, tractor, or both must be free to move during folding. On a slope, roll away could occur, causing an accident resulting in death, serious injury and substantial property damage.

Pinch Point and Crushing Hazards:

Keep people away from the drill and tractor during folding. The distance between the tractor and the seed structure increases by 3.2m (7.5ft) during folding. Drill, tractor, or both will move during this operation. Wings will swing forward. Risks include:

▲ Pinching or crushing at pivot points and at multiple sites in

pivoting assemblies. Stay clear of the wing sweep arcs. Coulters and row openers are sharp.

▲ Anything in between pull-bars and tongue, or in between

wing tool bar and tongue, will be crushed.

▲ Anyone or anything in front of or behind tractor or drill

could be run over.

CRUSHING HAZARD

To avod serious injury or death from crushing:

Mach ne moves rearward when fod ng w ngs forward

8 8 841C

Transport and Overhead Hazard:

Use wing locks (FIELD to ROAD). Use the transport hook cylinder lock channel. 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. Wing gauge wheel tires are off the ground in transport lift.

General Cautions:

▲ Fold only with markers resting in transport cradles.

Machine Damage Risk:

Do not fold with openers lowered.

▲ Fold only if hydraulics are bled free of air and fully charged

with hydraulic oil.

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 km/h or 20 mph at all times. 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.

Unexpected Wing Tilt-Down or Unfold Hazard:

Use transport locks (wing and centre section “ROAD” locks, and hook cylinder lock channel). 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 tilt down or unfold.

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 over-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.

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 R v C

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 maximum transport speed.

166-371M Table of Contents Index 2012-07-02

Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 51

Tractor Requirements

The ﬁgures in the table below represent a limited number of conﬁgurations. The weight of your drill can vary by thousands 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 near its limits, take your empty drill to a scale and get a precise weight.

Transport Checklist

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

mind. Folded, your NTA907 or NTA3007 is just under

4.1 m (13.5 feet) high and just under 3 m (10 feet) wide.

❑ Hitch.

Make hydraulic, electrical and optional braking connections. See “Hitching Tractor to Drill” on page 27.

❑ Close hopper lids (page 55).

Brake Operation (Option)

Main transport wheel brakes are standard on model NTA907. Brakes are not standard on model NTA3007. 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 29 - “Brake Hook-Up (Option)” page 120 - “Brake Troubleshooting (Option)” page 135 - “Brake Maintenance (Option)”

Roll-Away Hazard:

Block tires with wheel chocks before unhitching drill. The parking jack is not a sufﬁcient restraint for a drill parked on unlevel ground. An unsecured drill could roll away, causing an accident resulting in death, injury and substantial property damage.

Both versions of the service brake system to the tractor are spring-release on the drill. Drill braking is released shortly after unhitching the drill.

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.

Single-Line Hydraulic Brake Operation

In this system, a single hydraulic line from the tractor operates a de-intensiﬁer cylinder on the drill, which is coupled to the drill master cylinder . The drill brake hydraulic lines are separate from the tractor’s line.

With the hydraulic/hydraulic system, braking is immediately available when the tractor hydraulic system is active.

Dual-Line Air/Hydraulic Brake Operation

In this system, the “supply” (yellow or blue coded) line charges a reservoir air tank on the drill. The “service” (red coded) line meters air from the reservoir to a booster cylinder , which operates the drill’s hydraulic brake lines .

Ladder Operations

Ladder Safety Information

Refer to Figure 50 and Figure 51

Ladder General Information

The ladder on the left side of the mainframe provides access to the walkboard for material loading and routine lid/hopper maintenance. This ladder pivots diagonally, and is held in position by a spring-loaded pin.

Ladder may be lowered, used and raised with wings folded or unfolded, openers raised or lowered.

Falling Ladder Hazard: Make sure the pin is fully engaged when ladder is in the raised (folded) position. If the ladder is not pinned, it could slowly unfold during transport, striking other users of the roadway or ﬁxed obstructions. This could result in machine damage, property damage, serious injury or death. The ladder must be securely folded up for transport, and should be securely folded for storage, to discourage climbing by children.

Deploying Ladder

Use one hand to support the ladder, while pulling pin to the right. Slowly swing the ladder fully down.

The gas spring provides resistance to ladder motion in both directions. If the ladder swings freely, the spring may be in need of replacement.

Using Ladder

Ascend and descend the ladder while facing the drill.

Use the handrails when on the higher steps.

Falling / Crushing / Overhead Hazards:

Allow no one to ride on the ladder or walkboard while the machine is in motion. A simple fall could result in serious injury or death. A fall in transport could result in being run over by the cart or other vehicles. Someone standing on the walkboard also becomes the tallest point, higher than the transport clearance required.

Hopper Lids

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.

32454

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.

2012-07-02 Table of Contents Index 166-371M

Strainer

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;

• discourage hopper entry by children. Leave the strainer in place except during strainer and

hopper cleaning.

Check the strainer for residue prior to each loading operation. Remove, empty and return it to the hopper.

For strainer or hopper cleaning, the strainer lifts out when the lid is fully open, and bolts are removed.

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.

• Remove four restraining 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-secure the restraining bolts.

Meter Doors

Refer to Figure 56 and Figure 57 (which depict an earlier version of the meter without the gate handle extension and guards - do not operate without guards installed)

Each meter box has two distinct access doors on the bottom:

• Under DRIVING Gear: Clean-Out (for emptying hopper)

• Under DRIVEN Gear: Calibration (for meter sampling and meter clean-out)

The doors are closed during transport, loading and planting. They may be open slightly in storage if the hopper was not completely dry at clean-out.

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.

Auger Operations (Option)

Auger Safety Information

Electrocution Hazard, Auger:

Keep clear of overhead power lines when positioning auger. The auger can reach 5.3 m (17.5 feet) above ground level during positioning operations. If the auger gets too close to, or contacts a power line, nearly all metal parts of the drill and tractor will have lethal voltage present, and anyone touching them can complete the circuit to ground, resulting in serious injury or death. With very high voltages, electrocution can occur without direct contact.

Rotating Auger: To prevent serious injury or death, read instructions and safety information before operation. Keep hands, feet, hair and clothing away from rotating auger. Do not remove or modify any guards. Keep children well clear of work area.

Overhead Auger Injury Hazard:

Allow only operators near auger during use. Keep both ends of auger under control when tube contains material. Auger is balanced and fully supported by springs only when empty. If tube contains material, auger can move down suddenly when released. If one end of auger contains more material, auger can tip suddenly. Empty auger tube before storage. Use all provided pins and latches.

High Pressure Fluid Hazard, Auger 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.

Set FAN/AUGER selector valve to AUGER after auger deployment. Set FAN/AUGER selector valve to FAN before auger storage.

Pinch Point Hazard, Auger Support Linkage:

Allow only operators near auger during use. Keep hands away from auger support linkage during deployment and storage. If there is difﬁculty storing the auger, check that hydraulic hoses are not being pinched.

Auger Hydraulic Controls

Operating the auger involves: one valve (with two handles) on the auger, one (selector) valve on the drill mainframe, and the tractor lever for the auger/fan hydraulic circuit.

Tractor Lever for Auger

1. Before operating the auger/fan selector valve, shut down the auger/fan circuit. Shut off hydraulics entirely, or set circuit lever to Neutral or Float.

2. Check that the auger direction control valve is still OFF (as set at step 3 on page 60).

Selector Valve

Refer to Figure 63

This valve is located inside the right rear corner of the mainframe. It selects between auger and fan.

3. Move selector valve handle from Fan to Auger.

Rotating Auger: To prevent serious injury or death:

▲ Read instructions and safety information before operation.

▲ Keep hands, feet, hair and clothing away from rotating

auger.

▲ Do not remove or modify any guards.

▲ Keep children well clear of work area.

Auger Movement and Sudden Noise Hazards:

Do not operate the selector valve with the hydraulic circuit energized. Unexpected auger or fan operation can result.

Do not use this valve as the Start-Stop control for the auger.

Operate the valve with the tractor hydraulic circuit off, or set to neutral or ﬂoat. The handle has two positions.

Auger Selector Valve Positions

Handle Forward: Auger (make sure Auger control is

in centre-off position before moving handle to ). Handle Rear: Fan-enable (make sure circuit is off

before moving handle to ).

Figure 63

Auger/Fan Selector Valve

32392

166-371M Table of Contents Index 2012-07-02

Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 63

Auger Direction Valve

Refer to Figure 64

A valve toward the inlet end of the auger tube controls

the direction of auger helicoid screw rotation.This valve is “centre off”.

To allow ﬂow control by an operator at the outlet end, the control handle for the valve has an extension and second handle .

Use this valve as the Start-Stop and Forward-Reverse control for the auger. Set the valve to centre-Off when not

moving material at the moment.

4. With the direction control valve OFF, and the selector valve to AUGER, actuate the tractor auger/fan hydraulic circuit by setting the lever to Extend.

Note: The auger circuit is reversing. The tractor circuit

may be placed into Extend or Retract. However, if the tractor circuit placed into Extend, this provides a consistent experience for the auger operator, and reduces the risk of reverse fan operation.

5. Gradually move the handle away from centre-OFF. Note the direction of auger helicoid movement. When moving material, adjust speed as needed,

When auger operations are completed:

6. Set the auger direction control valve to centre-OFF.

7. Shut down tractor hydraulics, or set the auger/fan circuit to Neutral or Float.

8. Set the auger/fan selector valve to FAN.

NEUTRAL

Figure 64

Auger Direction Valve

26404 12713

Equipment Damage Risk:

Do not make sudden or full-stroke movements of the tractor hydraulic circuit controls with the auger circuit active. A remote circuit capable of operating the fan has enough hydraulic ﬂow to damage the auger motor.

2012-07-02 Table of Contents Index 166-371M

64 NTA907 or NTA3007 Table of Contents Index Great Plains Manufacturing, Inc.

Storing Auger

Make sure auger operations are shut down (step 6 through step 8 above) before storing auger.

Orient Inlet and Outlet

Refer to Figure 65

Only one inlet and outlet orientation is correct for storage. Although the auger can fully seat in the cradles in several orientations, there is risk of outlet damage during tilt/fold, and risk of inlet debris collection during transport and precipitation if not stored correctly.

1. Orient auger arm pivot.

If the arm is folded with the mid-arm pivot forward, pull the auger away from the drill and fold the mid-arm pivot back.

2. Rotate auger inlet-rear/outlet-forward.

Rotate in the direction that results in the most slack in the hoses.

3. Lock parallel arms at level.

Press on the parallel arm lock pin lever . Raise or lower the auger until the arms are level with the mainframe. Release the pin.

4. Swivel auger tube to outlet-facing-right.

Pull pin forward and rotate auger tube so that valves are on top. Outlet tube must face right (horizontally away from drill) to provide maximum clearance during fold and tilt.

5. Swivel inlet hopper to horizontal.

Pull pin at inlet. Rotate hopper to horizontal, inlet facing to drill left.

6. Remove rear arm pin from clevis on frame.

7. Seat auger tube in cradles. Secure arm with pin .

Refer to Figure 66

8. Close clamping straps , at cradles.

9. Secure latches. Make sure latch locks engage, leaving a gap between lock lever and latch handle.

Loading Materials

Loading Material Safely

Possible Agricultural Chemical Hazard: Treatments on seeds, and components of fertilizers, can be dangerous. Improper use can seriously injure persons, animals, plants, as well as damage soil and property.

▲ Do not use liquid treatments with the NTA907 or NTA3007.

▲ 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.

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 55.

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 enterprise policy. The venting tube structure in the hoppers has rungs for escape, and is not an entry ladder.

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.

2012-07-02 Table of Contents Index 166-371M

66 NTA907 or NTA3007 Table of Contents Index Great Plains Manufacturing, Inc.

Loading: Use a Tractor

3. Securely hitch the drill to a tractor with adequate weight and power. Park drill on solid, level ground. See Tractor Requirements, “Speciﬁcations and Capacities” on page 163. If a suitable tractor is not available, block multiple tires.

4. Raise openers (page 43) and fold drill (page 46). Tilt-up and hook may be necessary for later transport, but fold sufﬁces for provide easy access for material loading.

5. Lower and latch ladder (page 54).

Note: Static tongue weight of a loaded drill is about

2180 kg (4800 pounds) on level ground and more when facing downhill.

Loading: Select Hoppers to Use

6. Favour the rear hopper. The rear hopper is easier to load, and to unload if materials are expected to remain upon completion of application.

If applying the same material from both hoppers, consume the front hopper ﬁrst, rather than both at once. Remove a ﬁnal drive gear to shut off a hopper.

Loading: Air-Out System

Refer to Figure 67 (which depicts an earlier meter style without guards or door extension handles - do not operate without guards)

7. At each empty hopper to be loaded, if meter box clean-out door was completely closed, open it. See “Meter Doors” on page 57.

8. If any doors were opened, wipe seals and meter bottom ﬂanges clean. Close and latch clean-out 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.

Suggested Hopper Allocations

Empty Any Material

Seed Fertilizer

Seed (use ﬁrst) Seed (use second)

Material Rate 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.

10. With the fan running, check Hopper-lid and meter-box 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.

12. Open lid of hopper to be loaded (page 55).

Collection Chute Operation

Refer to Figure 69 and Figure 70 (Figure 69 shows the location of the storage bracket under the front hopper (light gray), and the chute after removal or before storage)

Because the front meter has only modest clearance below it to the centre row units, a collection chute is provided for calibration and clean-out.

The chute may be used with the front or rear meter, and may be installed to deliver material ahead or behind the meter.

Overhead Object Hazard:

Employ two persons to remove and store the chute. It weighs 17 kg (42 pounds) and can fall suddenly if improperly removed.

The chute is stored on four hooks of a bracket at the rear of the front hopper.

To remove the chute, have each person support the top with one hand, and lift the mid-point edge just free of the narrow lower bracket hook slots . Then raise the chute until the top pivot pins are free of the larger upper bracket hooks .

To store the chute, lift the pivot pins into the upper bracket hooks. Swing the bottom of the chute toward the lower bracket hook slots. Raise the bottom of the chute just enough to engage the mid-point edge in the lower hook slots.

1. Move the drill to a surface suitable for lowering the row units. The chute cannot be used with the centre openers raised. The drill does not need to be unfolded (and calibration or clean-out may be more convenient with the drill partially or fully folded).

2. Lower the row units (page 42).

3. If the task is calibration:

Open the calibration door on the meter, and wipe seed off the door and ﬂanges before installing the collection chute. See manual 167-085B for complete details of calibration.

Close the door. The chute cannot be installed with a door open.

4. Choose a desired orientation for the chute.

5. Slide the chute lips fully onto the meter side

rails .

6. For calibration, attach the calibration bag to the hooks at the outlet end of the chute.

166-371M Table of Contents Index 2012-07-02

7. Open the appropriate meter door for calibration or

clean-out.

For calibration, at the end of sample generation, it is likely to be necessary to wipe residual seed out of the chute and into the bag.

Calibration Crank

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 from, either side of the drill, all parts of the contact drive system are in motion, including parts out of sight of the crank operator.

Machine Damage / Invalid Results Risks: Rotate the hand crank only in the: clockwise direction on the left side, or counter-clockwise direction on right side. Operating in reverse can damage the meter gear box.

Note: If a variable rate gearbox is set to “0”, operating the

hand crank may fail to clear the meters of seed.

Crank General Information

Refer to Figure 71 (which depicts an earlier version of the meter, without handle extensions or guards - do not operate the meter without guards)

A hand crank is provided on the left side of the drill 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.

Figure 71

Hand Crank in Storage

29416

Material Loss Risk:

With material loaded, 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.

Operating the Hand Crank

Refer to Figure 74 or Refer to Figure 75

1. Raise drill (page 43). Contact drive tires cannot be turned by hand with drill lowered.

2. For more convenient cranking at contact drive wheels, fold wings (page 44).

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

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

4. Open calibration door on meter(s) being cleaned-out or tested.

5. For front meter, install collection chute (page 68).

6. For calibration, record weight of calibration bag. Hook bag to meter or chute under test.

7. Move crank handle from storage stob to shaft of left or right outside contact drive wheel.

8. Turn the hand crank to simulate meter operation during planting.

9. Return crank to storage stob at task completion.

Speciﬁc recommendations may be made in applicable manual sections. See: see “Meter Calibration” in the Seed Rate Manual, “Unloading Materials” on page 77, and “Storage” on page 82.

In general, you may operate the crank as fast as is comfortable. For reference, at a ﬁeld speed of 10 km/h (6.2 mph), the contact drive shaft rotates at 120 rpm (2 turns per second).

For clean-out, make sure the variable rate gearboxes are set:

• above “10” if the ﬁnal drive range gears are in High

Range mode, or

• above “80” if the ﬁnal drive range gears are in Low

Range mode.

To change variable rate gearbox and ﬁnal drive range gearing see “Setting Material Rates” on page 84.

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:

Sudden Auger or Fan Movement:

Set FAN/AUGER selector valve (if present) to FAN before activating tractor hydraulic remote for fan hydraulic circuit. If the fan does not start when slowly moving circuit lever, set lever to Float or Neutral and check selector valve.

Machine Damage Risk:

Protect motor seals: Fan circuit has three hoses. All must be correctly connected. Make sure that “SUMP” line is connected to tractor case drain.

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. The fanis running in reverse, the auger material movement direction is also reversed (relative to the decal illustrations).

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.

Refer to Figure 76

If an auger is installed on the drill, it shares the hydraulic circuit with the fan.

1. Turn on the seed monitor. Conﬁgure it for the materials and rates planned. Set reasonable alarm levels for low ﬂow rate alerts.

2. If no auger is installed, skip to step 5.

3. Set the fan/auger hydraulic circuit to neutral for setup.

4. Check the fan/auger selector valve is set to FAN. This valve is located inside the right rear of the mainframe.

5. With the tractor engine at low rpm, slowly Extend the lever for the circuit. Bring the fan up to recommended speed (page 98). Let the fan warm up for 15 minutes before planting.

6. Lower the drill 1.5 to3m(5to10feet) before planting is to begin. It takes a few seconds for seed to travel from the meters to the rows.

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.

Marker Operation (Option)

Dual markers are optional on the NTA907 or NTA3007. See “Markers” on page 159 for ordering information.

Marker Safety Information

Electrocution Hazard:

Keep clear of overhead power lines when operating markers. The markers can reach 7.3 m (24 feet) above ground level during folding and unfolding. If a marker gets too close to, or contacts a power line, nearly all metal parts of the tractor and drill will have lethal voltage present, and anyone touching them can complete the circuit to ground, resulting in serious injury or death. With very high voltages, electrocution can occur without direct contact.

Overhead Marker Hazard:

To prevent serious injury or death, do not allow anyone to stand near or beyond the end of the wings during marker operations. You may be injured if hit by a folding or unfolding marker. Markers may fall quickly and unexpectedly if the hydraulics fail. Marker arms are heavy and marker discs may be sharp.

Marker Pinch Point/Shear Hazard:

To prevent serious injury or death, do not allow anyone to stand near the end of the wings or and part of the markers during marker operations. The marker mechanism has numerous points where crushing or shearing injury can occur.

Sudden Marker Movement Risk:

To prevent unexpected marker operation, leave CFM Marker switch off (down) when markers are not in use.

Machine Damage Risk:

Operate markers only with drill completely unfolded. Extending a marker when tilted up may damage drill systems. Extending a marker when folded may damage the tractor.

Additional Marker Topics

2012-07-02 Table of Contents Index 166-371M

74 NTA907 or NTA3007 Table of Contents Index Great Plains Manufacturing, Inc.

Before Operating Markers

Marker circuits must be fully charged with oil and free of air before operation. Prior to ﬁrst use, or after maintenance, perform “Marker Hydraulic Bleeding” on page 133.

Marker Enable: Hydraulic Circuit Operation

Dual Marker Operation

Dual markers are on circuit which contains an adjustable automatic sequence valve. This valve is on a hydraulic circuit shared with Fold and Tilt cylinders.

1. To prevent unexpected marker movement when enabling the marker solenoid valve, set the shared circuit to Neutral or Float before operating the switches.

2. Enable markers at the CFM switch. Set Fold and Tilt off, then Marker on.

3. Clear the area within 5 m (15 feet) of marker arms on both sides of the drill.

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.

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

5. 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.

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

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

8. To extend other side, Extend once more, as at step 5.

Unloading Materials

Unloading Safety Information

Unloading materials has the same risks as loading material. Review the advisories on page 65.

Unloading Without Auger

1. Raise, fold, tilt and hook drill (page 44).

2. Position drill on smooth paved surface, or large tarp. Put tractor in Park and shut off tractor.

3. If unloading front hopper, employ the collection chute (page 68) or drape a tarp over the openers, to ease clean up.

4. Lower ladder (page 54), and open lid (page 56) on any hopper to be emptied. Unless both hoppers contain the same material, empty only one at a time.

5. If unloading fertilizer or treated seed, take same materials safety protection measures as for loading.

Refer to Figure 80 (which depicts an earlier version of the meter without handle extensions or guards - do not operate the meter without guards)

6. Open Calibration door ﬁrst. A small amount of material may fall onto the collection area.

7. Open Clean-Out door second. Expect material to ﬂow in signiﬁcant volume until the hopper is empty.

8. Install the calibration crank (page 69). Rotate it until no material ﬂows from the calibration door.

9. If the drill will not be used again for an extended period, complete the steps at See “Material Clean-Out” on page 124.

10. If unloading front hopper, and chute was not used, and openers were not covered with a tarp, brush excess materials from openers.

11. Move drill from collection area and recover materials.

12. Wipe down doors and bottom of meter.

13. Close doors. Store collection chute if used. For temporary parking or transport, fully close doors. For storage, close doors only until elastomer seals begin to touch meter housing, so that condensation can drain. Do not leave doors open wide enough for pest entry.

Possible Chemical Hazard:

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

Entrapment and Rapid Suffocation Hazard:

Auger Unloading: Front Hopper

The on-board auger is not designed for routine use as an unloading aid at the front hopper. With the polymer inlet hopper installed, the inlet end of the auger does not ﬁt under the front meter. Additionally, the outlet end of the auger may be too low for your collection bin or vehicle.

Great Plains recommends:

• planning operations to exhaust materials in the front

hopper (or use only the rear hopper for single-hopper tasks), or;

• use the non-auger unloading procedure (page 77) for

the front hopper.

Removing the polymer inlet hopper from the auger allows the auger to be swung under the front hopper meter. However, without the inlet hopper, the auger inlet will not catch all the falling material.

The loose inlet hopper can be placed under the auger inlet to catch the excess, and divert some of it to the inlet.

Unload the rear hopper ﬁrst. Then use the same steps as for unloading the rear hopper, with these changes:

7a. Before step 7(b) on page 78, remove the auger inlet

hopper.

7c. After step 7(b), manoeuvre inlet hopper under inlet.

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. 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 56.

3. Remove jack from storage position and pin securely to lifting stob on outside of drill tongue. See “Hitching Tractor to Drill” on page 27.

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

Note: Static tongue weight of a folded, tilted and hooked

drill can be as much as 2180 kg (4800 pounds).

5. Securely block drill tires with chocks (page 31) to prevent jack from digging or sliding off plate.

6. If drill is equipped with optional brakes, disconnect the brake 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.

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

8. 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. Large top hole is reserved for fan/auger case drain line.

9. Disconnect hydraulic brake line (option).

10. Disconnect the safety chain.

Storage

Store the drill where children do not play. If possible, store inside for longer life.

1. Unload all material in hoppers. See “Unloading Materials” on page 77.

2. Un-latch the hopper lids so that the seals are not in compression during storage. Route a chain or security cable through the hold-down U-bolt and the latch handle to prevent unauthorized entry, and prevent high winds from opening the lid.

3. Empty the Hoppers completely. Hand crank the meters several turns to empty completely. See “Calibration Crank” on page 69. Blow out the meters with air to remove all material.

4. Unless cleaned out at last loading or during unload above, deploy the auger, and run the motor in reverse until auger is completely empty. See “Auger Operations (Option)” on page 59

5. Return the auger to its cradle with the hopper in the extended storage orientation. See “Storing Auger” on page 64.

6. If equipped with optional air/hydraulic brake system, drain water from reservoir (page 137).

7. Remove the drive chains and store in oil.

8. Lubricate the drill at all points listed under “Lubrication and Scheduled Maintenance” on page 148.

9. Check all bolts, pins, ﬁttings and hoses. Tighten, repair or replace parts as needed.

10. Check all moving parts for wear or damage. Make notes of any parts needing repair or replacement before the next season.

11. Open the meter-box doors completely to release seal pressure and allow rinse water to exit.

12. Thoroughly wash the Hoppers with water to prevent corrosion from fertilizer or seed treatments.

13. Set doors to slightly open, but not wide enough for animals to enter the meters. Wire doors in place if needed. Do not store the drill with seals compressed.

14. Raise and stow the ladder, to discourage climbers.

15. Lubricate all points listed in Maintenance to prevent rust.

16. Clean drill of mud, dirt, excess oil and grease.

17. Grease exposed cylinder rods to prevent rust.

18. Use touch-up paint to cover scratches, chips and worn areas to prevent rust.

Setting Material Rates

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

The NTA907 or NTA3007 drill is a volumetric implement. For a given metering conﬁguration, rates will vary for materials with different density and granularity. The rate charts provide starting point, but calibration is essential for accurate application (even if using both meters for the same material at the same rate). Material rates are set independently for each hopper and meter.

Check Contact Tires

Reliable material rates are only achieved if the ground drive system is working properly. The transport tires and contact drive tires must be the correct size, and must be inﬂated to factory speciﬁcations. Check tire pressures, particularly the contact tire pressures, whenever loading seed or fertilizer. See page 166.

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 158) that change rates to 150%, 200% or ~25% vs. the factory standard shaft.

Refer to Figure 86 (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 has never been changed from factory standard, you have standard meter ﬂute shafts with 2 “stars” (4 halves) per outlet. How many and what type of “stars” you have determines which rate

Standard / Small Stars and Filler

chart to use.

Refer to Figure 87 (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,

1 1

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 185.

Find Your Chart and Rate

Standard “2 star” rates are in the main section of the Seed Rate 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 Dual Metering / High Rate Flutes

To ﬁnd the initial chart rate for dual hopper and/or alternate ﬂutes:

Adjustment for Small Seeds

Small Seeds rates are provided for somea, but not all 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.

In order to report 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.

See the DICKEY-john® Quick Start guide for more detailed instructions.

Density Units” - In metric mode this is always kg/litre. If conﬁgured for “U.S.” mode (U.S. customary units), this is pounds-per-bushel or pounds-per-cubic-foot.

“Density” - This is the density of seed being planted. Obtain this information from the material container/supplier. If unknown, use the value speciﬁed in the rate chart.

“Total Number of Towers” - This is the number of primary hoses coming off the rear meter box (this is always 4 for NTA907 or NTA3007).

“Calibration Constant” - This is the number listed in the seed rate charts for the rate you are planting or the number obtained from running the calibration routine for your speciﬁc seed.

Channel Setup Screen

Channel 1 setups are for the front hopper. Channel 2 setups are for the rear hopper.

“Type” - Set this to either “Gran Seed Monitor” or “Gran Fert Monitor” based on the type of material in each hopper.

“Material Name” - Choose the name of the material conﬁgured for each channel in steps 1 and 2 above.

“Sensor Constant” - [ 360 ]

“Gear Ratio” - [ 1 ]

“Channel Width” - is your Implement Width (swath) in inches (cm). Precise row/swath data is found on page 163 (for NTA907) and page 164 (NTA3007).

If the monitor inputs are correctly entered, the monitor is a handy tool for ﬁne tuning the variable rate gearbox setting. If the rate reported by the monitor does not match the desired planting rate, rotate the crank to adjust the variable rate gearbox control arm slightly so as to achieve the desired planting rate.

If the drill has the optional Variable Rate feature installed, also set up a Controlled Material and an Actuator Channel. See manual 166-263M for details.

Meter Rate Adjustment

Seed rate is determined by:

• Flute shafts (covered on page 84):

standard 2-star/1x rate, or optional 3-star/1.5x or 4-star/2x rates

• Single/twin hopper metering.(covered on page 85)

• Seed meter Final Drive Range gearing

• Variable Rate Gearbox setting

The Seed Rate 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 88 and Figure 89

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 labelled “DRIVING” and “DRIVEN”. The “DRIVING” shaft is the upper forward shaft. The “DRIVEN” shaft is the lower rear shaft.

Refer to the seed rate chart (or Fertilizer Rate chart), the table below, and Figure 88 and Figure 89 for setting the seed meter ﬁnal drive range.

Disable a Seed Meter

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

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 and Fertilizer Rate charts show the rate for each degree of the control arm rotation.

• Manual: On the standard NTA907 or NTA3007 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 (not shown). 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 chart, and reﬁned via calibration.

Refer to Figure 90

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 cotterr.

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 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 90

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.

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 86.

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 43): 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.

8. Open the calibration door of the meter being calibrated (page 57). The calibration door is the bottom door 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.

⁄10ha or1⁄10ac. See table at right.

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

Use a comfortable speed not exceeding 2 revolutions per second, which would simulate 10 km/h (6.2 mph) planting speed. A longer calibration is always more accurate, especially for low rates and small seeds.

⁄

hectare is easy to

calculate and is a minimum calibration run.

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

22. Accurately weigh the calibration bag plus material. If you have a digital scale, and set a “tare” on the scale, the reading is the sample net weight, so skip step 23.

23. Subtract the empty container weight to determine the application rate for1⁄10hectare (or1⁄10acre).

SampleWeight TotalWeight BagWeight–=

Manual Seeding Example; Net Weight (step 23):

Metric U.S. Customary

TotalWeight is: 23.26 kg gross

bag + sample

22.76 lbs. gross bag + sample

BagWeight is: 1.52 kg 3.36 lbs. SampleWeight is: 23.26 - 1.52

= 21.74 kg

22.76 - 3.36 = 19.4

24. Press the Stop softkey on the monitor and enter the sample net weight (SampleWeight).

The monitor responds with a Calibration Constant.

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

Push the Save softkey to accept this value.

25. If the sample was based on1⁄10hectare (or1⁄10acre), multiply the sample size by 10 to determine application rate per hectare (or acre) at the current variable rate gearbox setting.

CalibratedRate SampleWeight 10×=

Manual Seeding Example - Calibrated Rate

Metric U.S. Customary

CalibratedRate = 21.74 x 10

= 217.4 kg/ha

19.4 x 10 = 194.0 lbs./ac

This is 8% higher than our target rate. However, because the gearbox actuator effect is not linear, we cannot simply adjust the control arm by 4.8%.

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–=

Correction Difference (Seeding Example)

Metric U.S. Customary

TargetRate = 200 kg/ha 178.4 lbs/ac RateDifference = 200 - 217

= -17 kg

178.4 - 194.0 = -15.5 lbs

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 92, 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, re-mount 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 90.

33. Continue at “Calibration Close-Out” on page 96.

1 degree lower reduces rate by

201.3 - 195.4, or 5.9 kg 179.6 - 174.3, or 5.3 lbs

2 degrees lower reduces by

201.3 - 189.4, or 11.9 kg 179.6 - 169.0, or 10.6 lbs

3 degrees lower reduces by

The calibration difference was:

17 kg 15 pounds.

Adjusting down 3 degrees is a nearly ideal correction. So adjust the gearbox to a ﬁnal scale setting of:

Variable Rate (Servo) Calibration

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

the instructions at“Calibration for Manual Gearbox” on page 92.

Complete step 1 through step 13 beginning on page 90, 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 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.

36. Manually crank the meter for at least the number of turns shown in the table at right for

⁄10ha or1⁄10ac.

The exact number of revolutions, cranking rate, and precise starting and stopping handle angles are not critical, as the system reads meter revolutions accurately, and can compensate for shaft speed, seed size and partial turns.

What matters is getting a large sample, to reduce errors and increase conﬁdence in the calibration.

Note: By calibrating at or near target rate, and for1⁄10ha,

you establish a comfort level that the drill is set up correctly, in particular, that you are in the correct gear Range for the desired application rate.

Note: If no “Variable Cal Const” was selected during

material setup, crank no more than 2 revolutions per second (120 rpm) for most accurate results.
