Important Safety Information

Look for Safety Symbol

The SAFETY ALERT SYMBOL 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 indicates an imminently hazardous situation 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 indicates a potentially hazardous situation 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 indicates a potentially hazardous situation 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.

000 112 911 999

Be Familiar with Safety Decals

▲ Read and understand “Safety Decals” on page 6,

thoroughly.

▲ Read all instructions noted on the decals.

▲ Keep decals clean. Replace damaged, faded and illegible

decals.

2014-01-29 Table of Contents Index 196-538M

2 3N-40P 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.

Handle Chemicals Properly

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

▲ Do not use liquid treatments with drill.

▲ 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 100 feet

(30 m) 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.

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 attention

from a physician familiar with this type of injury.

196-538M Table of Contents Index 2014-01-29

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3

Use A Safety Chain

▲ Use a safety chain to help control drawn machinery should

it separate from tractor drawbar.

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

the gross weight of towed machinery.

▲ Attach chain to tractor drawbar 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.

Check for Overhead Lines

Drill markers contacting overhead electrical lines can introduce lethal voltage levels on drill and tractor frames. A person touching almost any metal part can complete the circuit to ground, resulting in serious injury or death. At higher voltages, electrocution can occur without direct contact.

▲ Avoid overhead lines during seed loading and marker

operations.

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 when

folding/unfolding, raising/lowering markers, raising/lowering openers, and transporting.

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 drill.

2014-01-29 Table of Contents Index 196-538M

4 3N-40P Table of Contents Index Great Plains Manufacturing, Inc.

Transport Machinery Safely

Maximum transport speed for drill is 20 mph (32 kph). Some rough terrains require a slower speed. Sudden braking can cause a towed load to swerve and upset.

▲ Drill must be raised, locked-up, folded and locked for

transport.

▲ Do not exceed 20 mph (32 kph). 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 national, regional and local laws.

▲ Do not tow a load that weighs more than 1.5x the weight of

the tractor. See page 29 for details.

▲ 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 170.

Shutdown and Storage

▲ Clean out and safely store or dispose of residual chemicals.

▲ Secure drill using blocks and transport locks. Lower

openers if not locked up.

▲ Store 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 on the Parts manual for additional information.

▲ Work in a clean, dry area.

▲ Put tractor in park, turn off engine, and remove key before

performing maintenance.

▲ Make sure all moving parts have stopped and all system

pressure is relieved.

▲ Disconnect battery ground cable (-) before servicing or

adjusting electrical systems or before welding on drill.

▲ 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.

196-538M Table of Contents Index 2014-01-29

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 5

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.

Safety At All Times

Thoroughly read and understand the instructions in this manual before operation. Read all instructions noted on the safety decals.

▲ Be familiar with all drill functions.

▲ Operate machinery from the driver’s seat only.

▲ Do not leave drill unattended with tractor engine running.

▲ Do not dismount a moving tractor. Dismounting a moving

tractor could cause serious injury or death.

▲ Do not stand between the tractor and drill during hitching.

▲ Keep hands, feet and clothing away from power-driven

parts.

▲ Wear snug-ﬁtting clothing to avoid entanglement with

moving parts.

High Pressure Fluid Hazard:

Only trained personnel should work on system hydraulics! Escaping ﬂuid under pressure can penetrate 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

The drive is compatible only with closed center, PC (pressure compensated) closed or LS (load sensing) hydraulic systems. Do not use an open center system.

medical attention from a physician familiar with this type of injury.

Refer to Figure 4

Great Plains hydraulic hoses have color coded handle grips to help you hookup hoses to your tractor outlets. Hoses that go to the same remote valve are marked with the same color.

Hydraulic Circuit Connections

The drill has three or four hydraulic circuits. The standard circuits power drive/locks, lift, and fold. If markers are present, they require a fourth circuit (or an additional selector valve sharing the fold circuit).

If the tractor has only one circuit rated for continuous ﬂow, reserve it for the hydraulic drive.

Great Plains Manufacturing, Inc. Table of Contents Index Preparation and Setup 17

Initial Setup

The following items need to be done for ﬁrst use, and some need to be re-done if the tractor changes.

Initial Tractor Setup

Three modules are mounted in the tractor cab. Route harnesses clear of moving parts, and allow enough slack for turns, especially on articulated tractors.

Veris Controller

The standard Veris hydraulic drive, controller module and DICKEY-john radar are factory-installed on the drill. The Veris console needs to be installed in the tractor prior to ﬁrst use. It includes suction cup feet that can support the console on glazing for extended periods.

Refer to Figure 8

Mount the console where the display is visible during planting, but does not obstruct vision of tractor or drill systems, and does not impair safe highway transport.

Installation instructions are found in an included Veris manual. Additional copies are available at:

www.veristech.com

Expanded operating information from that manual is found in this manual, starting on page 38.

Once the console is installed, you can enter the initial setup data by stepping through the calibration sequence but not actually operating the motor. See page 42.

Figure 8

Veris Controller Console

28326

Moving Chain Hazard Pinch/Crush Hazard Shaft Entanglement Hazard

Be careful when working around drill while tractor is running. Any movement detected by the radar gun (Figure 9) can activate the Veris hydraulic drive causing motion of chains, sprockets, shafts and seed meters.

Vision Hazard:

The DICKEY-john RVS II radar speed sensor is an intentional radiator of RF energy. Although its radiated energy level is far below the limits set by EN 61010-1: 1993\A2: 1995 - Chapter

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 per FCC 47 CFR Sec. 2.1091. DO NOT mount or use the radar in a manner inconsistent with its deﬁned use.

18 3N-40P Table of Contents Index Great Plains Manufacturing, Inc.

Seed Monitor Console

Refer to Figure 10

Consult the installation instructions included with the console, and mount it in a convenient location.

If the cab is particularly noisy, or the operator customarily wears a noise-cancelling headset, the alarms may not be audible. Mount the module where the controls and status indicators are visible during planting operations.

To use the speed and area functions of the seed monitor, it needs to be connected to a speed sensor. Although the drill includes a radar sensor, it is connected to the hydraulic drive system, and does not include Y-cable to share it with the seed monitor. Great Plains recommends connecting the seed monitor to a separate speed sensor, usually tractor-mounted.

Seed Monitor Setup

See the separate DICKEY-john manual for full details initial setup of the seed monitor. The following

Figure 10

Seed Monitor Cab Module

27390

information may be useful in that process.

Have the drill hitched to the tractor, and all harnesses connected. Although the monitor console can be operated with the drill disconnected, the Auto conﬁguration cannot be run. The parameter numbers are based on the Setup table in the DICKEY-john manual.

Refer to Figure 11

The monitor’s factory default is U.S. customary units of measure (if “METRIC” is not displayed, the console is in English/US customary units).

If metric units are desired, conﬁgure Setup Mode Parameter 21 (Units) before making any other settings. When Units are changed, all parameters with units have their values converteda.

Figure 11

28343

Seed Monitor Units of Measure

Refer to Figure 12

Navigate to the parameter 8 screen (Automatic Conﬁguration). Press the START/STOP/RESET button to run the auto-conﬁguration.

When complete, the following parameters are automatically set, and do not need to be entered: P10 - Number of Seed Modules and Seed Sensors P12 - Total Rows Conﬁgure

The seed monitor is not able to auto-detect everything it needs to know about the drill. The next page has cross-references to where to get the data needed.

196-538M Table of Contents Index 2014-01-29

Great Plains Manufacturing, Inc. Table of Contents Index Preparation and Setup 19

Refer to Figure 13

At the parameter 4 screen (Row Width), enter the row spacing of the drill (in inches or cm, to 0.1 precision). Use the base row spacing, even if re-conﬁguring for twin row or split row operation.

Use the exact row spacing from the charts beginning on page 176. If the chart shows a “swath-averaged” spacing, use that ﬁgure. It accounts for irregular spacing on TRS models and extra inches at wing joints. For example, on a 64-row 7.5 inch (nominal spacing) drill, the swath-average spacing is 7.56 in, or 7.6 in.

The monitor console uses Row Width, plus the auto-detected row count, to calculate an Implement Width. IMP WIDTH can vary slightly from the actual, due to round-off. For a 64-row 7.6 in drill, it computes 0486.4,

Figure 13

Row Width (Spacing) Setup

28348

which is about half a percent too wide.

Refer to Figure 15

If, at the parameter 5 screen, the computed Implement Width is not precise, you can override it to the value from the charts beginning on page 176.

In the example at right, the computed “0486.4” has been revised to the exact chart swath width of 484 inches.

If you operate with rows shut down for twin- or skip-row, revise the Implement Width to the chart value for that drill conﬁguration. You do not need to alter the Row Spacing parameter (the console accounts for the active row conﬁguration in the Split Row setup screen).

Refer to Figure 15

The parameter 9 screen conﬁgures which rows are operating. The factory default is Pattern 00 (all rows). This is correct for single-row (all rows), factory twin-row and all-row TRS operations.

If you operate with rows shut down for twin- or skip-row, change the Pattern number based on a comparison of the pattern table in the DICKEY-john manual, and the active rows from the charts beginning on page 176.

Also revise the Implement Width to the chart value for that drill conﬁguration. You do not need to alter the Row Spacing parameter (the console accounts for the row conﬁguration in the Split setup screen).

Point Row Switch Module

Refer to Figure 16

15. Choose a tractor cab location where the module does not obstruct vision, and the switches can be safely operated during planting passes.

16. Route the power leads to a source of +12 Vdc power capable of supplying 12.6A. Color code is red+, black-. Direct battery connection is acceptable; the controller module has its own master switch and fuse.

17. Use a tie to secure the power lead.

18. Route the controller harness to the tractor hitch. Use ties to secure the hitch lead.

Drill Setup Checks

Hydraulic Bleed

Bleeding the hydraulic system is not a routine daily setup item. If the system has not been charged since delivery, or any hydraulic work has been done (such as installing markers), “Bleeding Hydraulics” on page 145.

Drill Level

Drill sections are aligned and leveled at the factory, and re-checked during dealer pre-delivery. Level normally does not require routine adjustment before use. Great Plains does recommend checking it once prior to ﬁrst ﬁeld use. See “Level Frame Side to Side” on page 142.

Figure 16: 833-294C

Point Row Switch Module

Drill Option Setup

Even if factory- or dealer-installed, some optional items may need checking or adjustment prior to ﬁrst ﬁeld use. Install any that were not pre-installed.

Scrapers (Option)

If scrapers were ordered, and not dealer-installed, install them now per the instructions in one of the following manuals, which are available on the Great Plains website if not ordered or included:

Marker Setup (Option)

If markers are not installed, install them now per the instructions included with the markers.

Once installed, verify that they have been correctly bled (See “Bleeding Markers” on page 147).

Set initial marker extension - the distance to the mark on each side from the outside row unit on that side.

1. Move the hitched drill to a typical ﬂat ﬁeld.

2. Extend a marker on one side (see page 36). Pull forward a few feet or a meter or so to leave a mark.

3. Measure from the centerline of the outside row unit (whether that row unit is to be used or not) to the mark, along a line parallel to the wing.

Refer to Figure 230 through Figure 235 on pages 176 and 178

4. Check the measurement against the value recommended by Great Plains.

Refer to Figure 18

If the marker extensions need adjustment:

5. Loosen the nuts securing the U-bolt at the outer marker section.

6. Slide the inner tube in or out, and re-secure nuts.

See page 94 for further marker adjustments. Re-check marker extension when changing disk angle, or when inverting the disk, as both adjustments change the position of the centerline of the mark.

Install Weight Brackets (Option)

If weight brackets were ordered, and were not dealer-installed, install them now. Two kits (4 brackets) are supported, accepting ﬁve standard 100 pound (45 kg) “suitcase” tractor weights each, for a maximum additional weight of 2000 pounds (907 kg). Each empty bracket kits adds 121 pounds (55 kg) to the drill. Weights are not included with kits.

If only one weight kit is to be installed, use the “Outer” position.

Once the brackets are installed, see “Frame Weight”on page 93 for operating information.

Operating Instructions

This section covers general operating procedures. It assumes that setup items have been completed.

Experience, machine familiarity and this information leads to efﬁcient operation and good working habits. Always operate farm machinery with safety in mind.

Pre-Start Checklist

❑ Review “Important Safety Information” on page 1. ❑ Lubricate the drill as indicated under Lubrication,

“Maintenance and Lubrication” on page 137.

❑ Check the tires for proper inﬂation according to “Tire

Inﬂation Chart” on page 174.

❑ Check for worn or damaged parts and repair or

replace before going to the ﬁeld.

❑ Check all nuts, bolts and screws. Tighten bolts as

speciﬁed on “Torque Values Chart” on page 175

❑ Check hydraulic hoses, ﬁttings and cylinders for

leaks. Tighten, repair or replace before planting.

High Pressure Fluid Hazard:

Escaping ﬂuid under pressure can penetrate 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 attention from a physician familiar with this type of injury.

Moving Chain Hazard Pinch/Crush Hazard Shaft Entanglement Hazard:

Be careful when working around drill while tractor is running. Any movement detected by the radar gun (Figure 22) can activate the Veris hydraulic drive causing motion of chains, sprockets, shafts and seed meters.

Vision Hazard:

The DICKEY-john RVS II radar speed sensor is an intentional radiator of RF energy. Although its radiated energy level is far below the limits set by EN 61010-1: 1993\A2: 1995 - Chapter

12.4, it is advisable not to look directly into the face of the unit.

Lift / Lower

Machine Damage Risk:

Lower only when the drill is unfolded. The drill must be raised and locked up for folding and unfolding.

The drill has six rephasing lift cylinders that raise and lower the opener frame.

Six (6) transport locks are provided, two for the rockshaft (center forward) cylinders, and one each for the rear and wing caster cylinders. These assure that the drill stays raised during folding/unfolding, transport, storage, lubrication, maintenance and some setup/adjustment tasks.

Opener Operation Lowered

The “lowered” position of the opener frame is regulated by an adjustable valve, factory set for 2 inch coulter depth. See “Frame Height” on page 72 for adjustment.

Figure 23

Transport Locks Installed

20264 20266

Rephasing Lift System

Over a period of normal use the cylinders may get out of phase. This causes some implement sections to run higher than others when lowered. To minimize this, or rephase the cylinders, make the following steps your normal raise sequence:

9. Raise drill completely and hold the hydraulic remote lever on for several seconds until all cylinders are fully extended. Do this every third or fourth time you raise the drill out of the ground.

10. When all cylinders are fully extended, momentarily reverse the hydraulic remote lever to retract the system1⁄2inch (13 mm) to maintain levelness.

If implement is still not level after re-phasing, “Bleeding

Lift Hydraulics” on page 145 and “Level Frame Side to Side” on page 142.

Lift Cylinder Lock-Up

When moving the raised drill more than a short distance, or over any public road, or when performing adjustments or maintenance, do not rely solely on the lift cylinders to keep the mainframe raised.

Install transport locks.

Refer to Figure 25

1. If drill is folded, conﬁrm hitch is in Float. If drill is unfolded, hitch may be in any conﬁguration.

2. Raise the drill mainframe. See “Lift / Lower” on page 25.

3. Remove the transport locks from their storage positions . Install the transport locks on the cylinder rods , securing them with the same pins used for storage.

4. Lower the lift cylinders onto the locks.

Figure 25

Lift Cylinder Locks Installed

29283

Folding the Drill

Machine Damage Risk:

Fold only when the drill is raised and locked up.

Fold the drill on level ground with the tractor in neutral. If your drill has markers, be certain they are folded and their control switches are off before folding.

Pinch Point and Crushing Hazard. To prevent serious injury or death:

▲ Always use transport lift locks when drill is folded.

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

with hydraulic oil.

▲ Stay away from frame sections when they are being raised

or lowered.

▲ Keep away and keep others away when folding drill.

Refer to Figure 26

1. Set Drive/Lock selector valve to Lock.

Figure 26

2. Fold markers (Option). See page 36.

3. Raise drill with lift cylinders until cylinders are fully extended. Install lock channels over extended wheel-cylinder rods. Six cylinder rods total. See page 25.

4. Retract the Lock cylinder circuit lever to:

• disengage the tool bar locks (2),

• disengage swivel locks (2),

• disengage caster locks (2), and

• enable the self-latching transport lock (1).

Figure 27

Set circuit to Neutral. Do not Extend.

Note: There are two key points to remember when

operating the lock cylinders.

a. All seven lock cylinders are plumbed together,

and all move at the same time.

b. Operate the lock circuit lever (Retract/Neutral)

only once to fold. As the cylinders move, they unlock 6 points then stop in a “ready to fold position.” When the drill is folded, the 7th lock, spring loaded, snaps shut, locking the drill.

5. Extend the Fold cylinder circuit lever to slowly fold wings forward. The transport lock automatically captures the right wing tool bar for transport.

Note: It may be necessary to ease forward slightly with

the tractor to assist wings in folding completely.

Unfolding the Drill

Machine Damage Risk:

Unfold only when the drill is raised and locked up.

Unfold the drill on level ground with the tractor transmission in neutral.

Crushing, Pinch-Point and Overhead Hazards. To prevent serious injury or death:

▲ Always use transport locks when drill is folded.

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

with hydraulic oil.

▲ Stay away from frame sections when they are being raised

or lowered.

▲ Keep away and keep others away when unfoldingdrill.

Note: When unfolding, operate the lock circuit exactly in

reverse of folding. Operate the circuit once (Extend/Neutral). Remember that when the cylinders move, they release one lock, and enable six others, stopping in a “ready to unfold” position. As the drill is unfolded, the six spring loaded locks snap shut, locking the drill.

Refer to Figure 29

1. Check selector valve set to Locks.

2. Extend the Lock cylinder circuit lever to:

• disengage the self-latching transport lock,

• enable two tool bar locks,

• enable two swivel locks, and

• enable two caster locks. Set circuit to Neutral. Do not Retract.

Refer to Figure 23 and 25 on page 25

3. Raise the drill. Remove lock channels from all six wheel cylinders. Store lock channels.

4. Activate fold hydraulics and slowly unfold the until wings are fully unfolded and all spring loaded locks have snapped into position.

5. Lower the drill.

Refer to Figure 29

6. Move selector valve handle from Locks to Drive.

Transport

Electrocution Hazard. To prevent serious injury or death from electric shock, keep clear of overhead power lines when transporting, folding, unfolding or operating drill components. Machine is not grounded. At higher voltages, electrocution can occur without direct contact.

Great Plains recommends transporting the drill without seed loaded. Although designed for highway movement with full seed boxes, the additional weight of seed may cause the drill to exceed the rated towing and stopping ability of the tractor, makes the drill more difﬁcult to control and stop, and increases wear on tires and wheel bearings.

Make sure the tractor weighs at least drill, including any material load. Check the table on page 30 for typical weights of various conﬁgurations.

⁄3(67%) of the

Loss of Control Hazard:

Towing the drill at high speeds or with a vehicle that is not heavy enough can lead to loss of vehicle control. Loss of vehicle control can lead to serious road accidents, injury and death. To reduce the hazard:

▲ Do not exceed 20 mph (32 kph).

▲ Do not tow a drill that weighs more than 1.5 times the

weight of the towing vehicle.

Pre-Transport Checklist

Before transporting the drill, check the following items.

❑ Make sure the weight of the tractor equals or

exceeds the value speciﬁed for your drill conﬁguration.

❑ Marker Checklist Complete: Markers must be

folded.

❑ Master Switches Off: Check that the Veris and point

row (if any) master switches are off while transporting.

❑ Drill Raised and Locked: Lift transport locks

installed. Wings folded and locked, with circuit lever in neutral.

❑ Tires: Check that all tires are properly inﬂated as

listed on “Tire Inﬂation Chart” on page 174.

❑ Bystanders: Check that no one is in the way before

moving. Do not allow any one to ride on the drill.

Figure 32

18857

Marker in Transport Cradle

❑ Warning Lights: Always use tractor and drill

warning lights when transporting the drill.

❑ Clearance: Know the maximum dimensions of the

tractor and drill in transport position and follow a route that provides adequate clearance from all obstructions, including overhead lines. See “Speciﬁcations and Capacities” on page 170.

❑ Stopping Distance: Allow sufﬁcient stopping

distance and reduce speed prior to any turns or maneuvers. If the drill is transported full, allow extra stopping distance.

❑ Road Rules: Comply with all national, regional and

local laws when transporting on public roads.

❑ Watch Trafﬁc: The drill boxes obstruct a portion of

your rear view. Be prepared for sudden maneuvers from following vehicles.

Typical Drill Weights

a. Weights include frame-mounted coulters and typical press wheels, but not row unit accessories or other options, which can alter the

total weight substantially. If table weight is near recommended limit for the tractor, obtain a precise weight for the empty drill at a scale.

Loading Seed

To unload seed, “Cleaning Out Meters” on page 138.

Misstep Hazard:

Watch your step when walking on drill ladder and walkboard. Falling from drill could cause severe injury or death.

Great Plains recommends loading materials after the drill has been transported to the planting ground.

Seed is heavy. A full load of dense seed adds over 6000 pounds (2780 kg) to the drill. Pre-loading substantially increases transport hazards:

• Stopping distance increases.

• Turns are more difﬁcult to initiate and more difﬁcult to stop, due to the inertia of the load.

To load materials:

1. Load only in dry conditions.

2. If the seed is treated, wear protective equipment

recommended for the hazards.

3. Lower the drill.

4. Open the lids for the boxes.

5. Remove any debris or obstructions from the boxes. If

other seed needs to be ﬁrst removed, see “Cleaning Out Meters” on page 138.

6. If not planting all rows, shut off unused rows. See

page 79.

7. If seed lubricant is to be used, and was not

re-applied to the seed, determine the total amount to be added, and place a small amount of it in the empty seed boxes.

8. Load seed. Load or spread materials evenly across

all partitions. Use a tool or gloved hand. Add seed lubricant periodically (every other bag or so).

9. Make a note of the seed quantity loaded, for later

conﬁrmation of population or application density desired.

10. Close and secure the box lids.

Ezee Glide Plus Lubricant To maximize performance of Great Plains metering systems, it is imperative to use only “Ezee Glide Plus” lubricant. “Ezee Glide Plus” Talc-Graphite lubricant is mandatory for all seeds, especially treated or inoculated seed. Thorough mixing of seed and added lubricant is

required.

Recommended usage:

For clean seeds other than milo and cotton sprinkle one cup of Ezee Glide Plus Talc per 4 bushels or units (170 ml per 100 liters) of seed.

For milo and cotton double the application to one cup (or more) per 2 bushels or units (335 ml per 100 liters) of seed.

Adjust this rate as necessary so all seeds become coated while avoiding an accumulation of lubricant in the bottom of the hopper.

For seed with excessive treatment, or for humid planting environments, increase the rate as needed for smooth meter operation.

For Finger Pick Up Meters Only

Use only approved Graphite Powder available from Great Plains Mfg. Inc. or Precision Planting to ensure proper lubrication of ﬁnger pickup corn seed meters.

Recommended usage:

For ﬁnger pickup meters, add one tablespoon (15 ml) of graphite for each unit of seed corn (80,000 kernels).

In high humidity conditions, or seeds with heavy seed treatments, increase the application to two tablespoons (30 ml).

If delivery of seed from the hopper to the ﬁnger meter is an issue, add “Ezee Glide Plus” talc and graphite blend at a rate of one cup (237 ml) per 4 units of seed. Adjust until issue is resolved.

Irritation and Chronic Exposure Hazard:

Wear gloves. DO NOT use hands or any part of your body to mix seed lubricant. Wear a respirator when transferring and mixing. Avoid breathing lubricant dust. Not an acute hazard. May cause mechanical eye or skin irritation in high concentrations. As with all mineral spills, minimize dusting during clean-up. Prolonged inhalation may cause lung injury. Product can become slippery when wet.

Seed Rate

Seed rate on this family of drills is controlled by:

• selection of seed meter, and seed wheel or ﬁnger count, and

• the rate set on the hydraulic drive console.

About Hydraulic Drive Rate

Before it can control seed rate, the hydraulic drive console must be:

• conﬁgured with information about your drill and intended planting speed,

• conﬁgured with a calibration number for the seed, meter and rate range, and;

• calibrated to ﬁne-tune the seed rate calibration number and ground speed radar. Calibration is essential for volumetric seeds, because the seed metered by each meter wheel revolution varies with the seed.

Calibration is described starting on page 42.

Refer to Figure 33

With those steps completed, ﬁeld seeding rate is controlled manually by adjusting the target “set=” rate using the ⇑/⇓ arrow buttons. Rate can also be controlled by a pre-loaded “recipe” or an external GPS controller.

In ﬁeld operation, the hydraulic drive console displays:

set= the currently active desired seeding rate out= the current system seeding rate spd= (over number), the current speed

Figure 33

Console Planting Display

25295 28334

Seeding Depth

Refer to Figure 33

Seeding depth is controlled by one or more of:

• frame-mounted coulter depth (if present),

• unit-mounted coulter depth (if present),

• side depth gauge wheel (Series dependent), and;

• and press-wheel height (Series dependent).

Adjust frame height ﬁrst (page 72), then make row unit adjustments. Each opener Series is covered separately:

Point Row Switches

The hydraulic drive motor operates whenever the speed radar detects motion. The Point Row system determines whether or not that motion is coupled to the meter drives, by controlling the electric clutches. The implement lift switch is part of the Point Row system.

A Point Row troubleshooting chart is found on page 129.

Refer to Figure 35

Note: The Pump switch has no function on 3N-40P

drills conﬁgured byGreat Plains. Unless connected to aftermarket equipment, leave it off.

When Not Planting or Calibrating

Set the Master switch OFF when you do not intend to meter seed.

Entanglement Hazard:

If the hydraulic drive system is on, and the drill is lowered (or the Master switch is in CAL), unexpected motion of chains, sprockets, shafts and seed meters can occur if the speed radar detects motion, such as someone moving near the radar.

Normal Full Pass

1. Set Master switch ON (up) Set all sections ON (up). Check that corresponding lamps are on.

2. Height switch automatically energizes clutches when row units are lowered.

L C R

Point Row in Pass

3. Turn desired sections off as non-planting regions are reached.

4. Turn the sections back on before commencing next full-width pass.

Point Row CAL Mode

When the drill is raised, the lift switch normally causes the Point Row Monitor to disengage the clutches for each drill section. To keep one or more clutches engaged during hydraulic drive calibration, set the Master switch to CAL.

For a typical 3-row calibration, set the Left section switch on, and the center and right section switches / off during calibration.

Field Operations

This section presumes that all pre-operation checks have been made on drill, and drill is hitched and loaded with seed.

Final Field Checklist

❑ Drill unfolded and raised. ❑ Selector valve set to hydraulic drive. ❑ Hydraulic drive console set per seed rate calibration. ❑ Check all seed tubes secure. ❑ Check all row conﬁgurations identical (except where

compensating for tire tracks, etc.).

If you desire to verify that all meters and seed tubes are working, you can run a Veris calibration for 4 seconds (the minimum time) and “KEEP OLD” when it presents a proposed new calibration number. See page 42.

Planting Sequence

1. All Clutch/Point Row switches up (except Pump). Check lamps illuminated.

2. Press Veris “ON/VR” button once. Check LED above button illuminated.

3. Pull forward to ﬁeld.

4. Lower drill to ﬁeld position.

5. Move lever for hydraulic drive circuit forward and lock it open.

6. Option: Extend marker side desired.

7. Option: Shaft Monitor ON

8. Press Veris “ENGAGE” button once. Check LED above button illuminated.

9. Accelerate to planting speed.

10. Raise drill for turns (drive stops automatically).

11. Option: Retract and extend markers at turns.

Stop early in the ﬁrst pass to verify:

• Openers are at correct depth.

• Seed is ﬂowing to furrows.

• Press wheels are covering furrows as desired.

Monitor the seed level indicators on the seed box. After a third or more of the ﬁrst seed load has been planted, stop and check the seed boxes from above. Observe seed monitor for row out-of-limit alarms.

Seed consumption is uneven, and end rows run out before mid-section rows. Re-load seed when the level indicators near Empty.

Figure 36

DICKEY-john Radar

Moving Chain Hazard Pinch/Crush Hazard Shaft Entanglement Hazard:

Be careful when working around drill while tractor is running. Any movement detected by the radar gun can activate the Veris hydraulic drive causing motion of chains, sprockets, shafts and seed meters.

Vision Hazard:

The DICKEY-john RVS II radar speed sensor is an intentional radiator of RF energy. Although its radiated energy level is far below the limits set by EN 61010-1: 1993\A2: 1995 - Chapter

12.4, it is advisable not to look directly into the face of the unit.

Certain Machine Damage:

Do not back up with openers in the ground. To do so will cause severe damage and opener plugging.

Marker Operation (Option)

Markers are on a separate hydraulic circuit on the drill. Before operating markers, make sure they are properly bled as described in “Bleeding Markers” on page 147.

Dual markers are equipped with a sequence valve to control lift sequence. Starting with both markers up, the sequence is:

1. Activate tractor hydraulic lever; right marker lowers while left marker stays up.

2. Reverse hydraulic lever; right marker raises while left marker stays up.

3. Activate hydraulic lever; left marker lowers while right marker stays up.

4. Reverse hydraulic lever; left marker raises while right marker stays up.

5. Pattern repeats.

Folding speed of dual markers is adjusted with adjustment screws on sequence valve body. Because excessive folding speed may damage markers, adjust markers to a safe folding speed according to “Marker Speed” on page 147.

Note: To get both markers in the lowered position at the

same time, activate hydraulic lever to lower one marker. After marker is lowered, move lever to opposite position then quickly reverse lever and hold until other marker is lowered.

Basic Operation

Power Up

Refer to Figure 39

To power-on the controller, press the ON/VR button once. This powers up the console in Manual mode, and also powers up the external module on the drill (if connected).

The green LED above the button illuminates, and a display appears showing:

set= the currently active seeding rate

Shortly thereafter the display also shows:

spd= (over 0.0), the current speed, and out= 0.0, the current system operating rate.

Once the console is powered up, the ON/VR button toggles between Manual and VR (Variable Rate) mode.

Note: It is possible to enter all setup information with the

console connected to power, but disconnected from the drill. Operations requiring motion, such as calibrations, must be performed hitched (but generate harmless errors if undertaken with only the console powered).

Seed Rate

In Manual mode, use the ⇑/⇓ arrow buttons to set the desired seed rate (in pounds/acre or kg/ha). Or use FUNCTION to select Preset mode, and the ⇑/⇓ arrow buttons to alternate between preset rates (see page 56).

In VR mode, the seed rate is set by an external “recipe” program or external controller. The ⇑/⇓ arrow buttons can override the current rate. VR mode is not documented in this manual.

Power Off

Press the OFF button to shutdown.

3. Before planting, conduct a seed rate Calibration (page 42) and ground speed Calibration (page 53).

4. Engage the hydraulic ﬂow by pushing FORWARD on the tractor remote hydraulic lever. The remote lever must be LOCKED OPEN in this position to provide constant ﬂow to the drive motor.

John Deere tractors with Sound-Gard™ body: Use lever lock clip to lock lever forward. See your tractor dealer for lock purchase and installation.

John Deere 7000 Series tractors: Rotate valve detent selector to motor position to lock lever in forward position.

John Deere 8000 Series tractors: Set timer to continuous. Push lever forward until detent clicks.

Case-IH Magnum tractors: Lock lever forward in detent position. You may need to turn up detent pressure to its maximum setting. Do not tie hydraulic lever past detent position with a strap. See your tractor dealer for details.

Other tractors: Lock lever forward in detent position. You may need to turn detent pressure to maximum or use a mechanical detent holder to hold lever forward. See your tractor dealer for proper means of providing constant ﬂow.

5. Press ENGAGE button to activate drive. Green light above ENGAGE button illuminates.

Note: If you do not move within 10 seconds, the

automatic disengagement feature disengages the drive. To begin planting again, press ENGAGE.

6. The Console display shows two numbers while operating: “Set” rate is the rate you tell the system to plant, and the “Out” rate is the calculated rate based on the actual rotations of the drive. The “Out” reading is monitoring the drive system; it isn’t monitoring population. It veriﬁes that the drive system is functioning properly.

Note: The “Out” readings normally ﬂuctuates within 5%

of the “Set” rates. This ﬂuctuation is evidence of the drive system compensating for normal variations in ground speed.

7. If “Out” rate varies from the “Set” rate by more than 20%, an audible alarm sounds.

8. If Controller is powered directly from the battery or via unswitched power port, make sure to power Console off when tractor is shut down, in order to prevent tractor battery drain.

When calibrating, make sure that you choose a calibration speed that is representative of your average planting speed.

Seed Rate Calibration

Seed rate calibration consists of:

a. Setting up to collect seed at onea or more rows

(typically 3), using an approximate calibration number.

b. Running the hydraulic drive (with drill stationary) for

a short period of time, twice:

- once to prime the seed cups, and

- once to generate the sample.

c. Weighing the collected seed, and determining

amount per row.

d. Entering that weight on the console. The controller

uses it to calculate a more precise Cal. number.

Tools required:

• small container(s) to capture seed at one or more openers, and

• a scale with a capacity great enough to weigh the container(s)+seed, and precise enough to register the difference between that and the empty container(s).

Figure 41

Calibration: Initial Screen

28251

Seed Rate Calibration Steps

In the steps which follow, the examples are based the conﬁguration at right.

1. Unfold the drill.

The wing drive shafts cannot turn with the drill folded. U-joint damage will occur if attempted.

2. Load an amount of seed, equal to about twice the

expected sample size, over one or more rows near the end of the left wing seed box. The expected amount of seed is determined by you. The controller calculates the run-time necessary to generate that amount at a single row.

Great Plains suggests sampling an amount that is at least1⁄4pound (0.1 kg), and requires at least 100 seconds. At typical planting speeds, this is about one row for one acre (or one row for half a hectare). Divide your intended seed rate by your row count.

SeedRate

SampleSize (lbs)

SampleSize (kg)

3. Raise and lock-up the drill if capturing seed below

openers.

-------------------------

RowCount

SeedRate

----------------------------------

RowCount 2×

Example drill conﬁguration: Model: 3N-4010P-4810 Row spacing: 10 in RowCount = 48 Seed: long grain rice Desired seed rate: 50 pounds/acre

Sample size for our example: SeedRate = 50 (lbs/ac) RowCount = 48

1.04 = 50 / 48

SampleSize is 1.04 lbs

Load 2 lbs or more for testing.

a. For short run times and/or small samples, increase the accuracy of the results by sampling multiple rows, and calculating the average.

For adjacent rows, pull the seed hoses off at the opener, and route them to a common collection container.

Refer to Figure 43

7. Turn on Controller Console by pressing ON/VR button. Green light above ON/VR button illuminates.

8. Use ⇑/⇓ arrow buttons to set desired planting rate, the example, 50.0 pounds/acrea.

Note: Set the desired rate before performing a

calibration, as this value is used by the controller to calculate sample run time. If the rate is not set, the sample run time will be incorrect, or you may get “TIME TOO LOW/HIGH” errors that cannot be cleared by adjusting the expected sample size.

Refer to Figure 44

9. Press FUNCTION button until CALIBRATION NUMBER window appears.

10. Select drive calibration number based on row spacing and seed, from “Seed Rate Calibration Steps” on page 42. You may also use an initial value developed from a previous calibration of similar seed.

Adjustments

To get full performance from your drill, you need an understanding of all component operations, and many provide adjustments for optimal ﬁeld results.

The 3N-4010P, 3N-4010HDP, 3N-4020P and 3N-4025P have double-disk parallel-arm openers with depth-controlling press wheels. This system provides accurate depth control and seed placement over uneven terrain. The following is an introduction to the basic seeding components and how they work.

Each opener is mounted on a ﬂoating opener frame, held parallel to the ground. Opener bodies are staggered for easy soil ﬂow. A spring provides the down pressure necessary for opener double disks to open a seed furrow. The spring allows openers to ﬂoat down into depressions and up over obstructions. Trailing press wheels close the furrow. Individual openers can be adjusted to account for tire tracks.

Even if your planting conditions rarely change, some of these adjustment items need periodic attention due to normal wear.

Planting Depth

Setting nominal planting depth, and achieving it consistently, is affected by multiple adjustable drill functions, from greatest to least effect they are:

• Coulter Height;

• Opener Depth (Press Wheel and/or Side Wheel)

• Row Unit Down Pressure;

• Frame Weight;

• Disk Blade Adjustments (as blades wear).

Frame Level

When beginning planting, check frame level with row units in level ground.

If one or both wings are angled up or down, check and adjust the following items:

•“Level Frame Side to Side” on page 142

• coulter depth setting - “Frame-Mounted Coulters”on page 75

• coulter mount adjustment - “Individual Frame-Mounted Coulter Depth” on page 77

• coulter down-force spring setting - “Frame Weight”on page 93

• row unit down-force spring setting - see: “10P Series Row Unit Down Pressure” on page 96 “10HD Row Unit Down Pressure” on page 103 “20P Series Row-Unit Down Pressure” on page 110 “25 Series Row Unit Down-Pressure” on page 116

• press-wheel height setting - see: “10 Series Opener Depth” on page 99 “10HD Press Wheel Adjustments” on page 107 “20P Series Press Wheel Adjustments” on page 114 “25 Series Press Wheel Adjustments” on page 122

Frame Height

Frame height is determined by an adjustable hydraulic depth control valve, and has a signiﬁcant effect on planting depth.

Frame height adjustment methods depend on coulter conﬁguration. Frame-mounted coulters (FMC) are standard on some 3N-40 models and optional on others. The 3N-4010HDP accepts either FMC or unit-mount coulters (UMC), although only one type of coulter can be installed simultaneously.

For adjustments:

Refer to Figure 89

1. Frame-Mounted Coulters (FMC)

frame height information begins on page 75.

2. Unit-Mounted Coulters (UMC, 10HD and 25P only)

frame height information begins on page 101.

3. No Coulters

use the same frame height setup as UMC, page 101.

Frame Height without Frame-Mounted Coulters

Use these instructions with a drill having no coulters, or having unit-mounted coulters (UMC). Adjustments to individual unit-mounted coulters themselves (10HD models only) are on page 101.

Refer to Figure 90

Frame height is measured from the bottom of the

opener tool bar (the largest of the tool bars), and is measured with the drill lowered.

The recommended height depends on your ﬁeld conditions (see table below), and whether unit-mounted coulters are installed.

For no-till conditions, a 26 in. (66 cm) height allows the opener parallel arms to run parallel to the ground giving the opener the maximum upward or downward ﬂotation.

In loose or conventional planting conditions, a frame height above 26 in. (66 cm) helps keep the no-till spring forces from burying the openers.

Note: Setting the frame above the 26 in. (66 cm) limits

the opener downward ﬂotation.

Note: Running with the frame below 26 in. (66 cm) limits

opener upward ﬂotation and could cause opener damage especially at center of the drill.

Crushing Hazard: Make all down-stop adjustments with circuit in neutral and drill raised (actuator plunger not in contact with down-stop). Loosening the down-stop with circuit active and drill lowered results in rapid lowering of the frame.

Height Mis-setting Risk: Make sure the drill is level and the lift system bled and re-phased before adjusting the tool bar height. If the center section does not consistently stop at the set height, or the wings do not run at the same height as the center, the lift system may have air or be out of phase (above), or the wings may not be level. See “Frame Alignment and Level” on page 142.

Refer to Figure 91

The lift system includes an adjustable stop valve to ﬁx the height of the opener frame when the drill is lowered.

Make sure the drill is level and the lift system bled and re-phased before adjusting the tool bar height.

To adjust the stop height:

1. Move to smooth level ground representative of ﬁeld

conditions.

2. Lower the drill and measure the present tool bar

height. If the drill cannot be fully lowered due to row unit spring settings, temporarily move the cams to a lower setting, or out of notch entirely.

3. Raise the drill.

4. Loosen the knob on the stop .

5. Adjust the stop position on the tube . Adjust up

(to raise) or down (to lower). Adjust by half the last difference. Secure the stop with the knob bolt .

6. Lower the drill and measure the tool bar height. If the

error is more than about1⁄8inch (3 mm), repeat the adjustment process from step 3.

7. Raise and lower several times and conﬁrm that the

drill stops consistently at the new height.

Note: It is important that all tires remain in ground contact

to maintain frontto rearlevelness. Setting the depth control too deep combined with high opener spring force can cause the drill to tip forward when planting, which may cause plugging.

Frame-Mounted Coulters

The factory conﬁguration of frame-mounted coulters (FMC) is to run about 1 inch (2.5 cm) deeper than the opener blades. Based on your conditions and experience, you can readjust the depth drill-wide, or just at some rows.

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

With frame-mounted coulters, the coulter depth controls opener depth and performance. Set the frame height to achieve the desired coulter depth.

There are three adjustments for frame-mounted coulters:

Refer to Figure 92

1. Frame height - the running depth of all coulters as a group. This is set by a hydraulic stop, the next topic.

2. Individual coulter depth - a mechanical adjustment for a few rows in tire tracks. See page 77.

3. Individual coulter down-force - this is a spring adjustment for rows in tracks, or all rows - in unusually light or heavy no-till conditions. See page 78.

Frame Height - Frame Mounted Coulters

Refer to Figure 93

In regular or heavy no-till conditions, set

the coulter depth to about 1 inch (2.5 cm) deeper than

seeding depth.

For example, if

the desired seeding depth is 1 inch (2.5 cm), set

the coulters to run at 2 inch (5.1 cm) deep.

Setting coulters too deep for conditions can cause opener plugging and uneven or too-deep seed depth. In light no-till or conventional till conditions, it may be necessary to set coulter depth to less than 1 inch (2.5 cm) below seeding depth , or even1⁄4inch (6 mm) above seeding depth.

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

Crushing Hazard:

Make all down-stop adjustments with circuit in neutral and drill raised (actuator plunger not in contact with down-stop). Loosening the down-stop with circuit active and drill lowered results in rapid lowering of the frame.

Height Mis-setting Risk:

Make sure the drill is level and the lift system bled and re-phased before adjusting the tool bar height. If the center section does not consistently stop at the set height, or the wings do not run at the same height as the center, the lift system may have air or be out of phase (above), or the wings may not be level. See “Frame Alignment and Level” on page 142.

Refer to Figure 94

Note: The change in coulter height is greater than the

change in down-stop adjustment. Make adjustments in small amounts.

The lift system includes an adjustable stop valve to ﬁx the height of the opener frame when the drill is lowered.

To adjust the stop height (assuming a desired 11⁄4inch / 3.2 cm coulter depth):

1. Move to smooth level ground with soil as similar as possible to ﬁeld conditions.

2. Lower the drill until the coulter blades just touch the ground. Hold that height by setting the lift circuit to neutral.

3. Loosen the knob on the stop .

4. Adjust the stop position on the tube until it just touches the actuator .

5. Raise and then fully lower the drill.

6. Pull forward 10 feet (3 m) and stop.

7. Measure the depth at which the coulters are running. Measure only in non-tire-track rows where the coulter springs are not in compression (arm is at full extension). If the coulters are at the desired depth, no further adjustment is necessary. Skip to step 11.

8. Raise the drill and set the lift circuit to neutral.

9. Adjust the stop up (to raise depth) or down (to lower depth). Adjust in small increments. Secure the stop with the knob on the bolt .

10. Check the new setting starting at step 5.

11. Raise and lower several times and conﬁrm that the drill stops consistently at the new height.

Note: It is important that all of the tires remain in contact

with the ground to maintain levelness of machine from front to rear. Setting the depth control too deep combined with high opener spring force can cause the drill to tip forward when planting, which may cause plugging.

Running with the front tires ﬂoating or skimming on the ground will cause uneven coulter depth and may cause uneven seed depth.

Before making any adjustments to individual frame-mounted coulters, setup the seeding depth on the row units, and verify that the coulter tool bar height is set for your conditions.

Individual Frame-Mounted Coulter Depth

The running depth of all coulters is adjusted simultaneously by changing the tool bar height. Adjusting the height of a small number of coulters may be useful for rows in tire tracks.

Adjust individual coulters as follows.

1. On level ground, lower the drill until coulters just touch the ground.

2. Raise the drill by the extra amount you need to lower the rows in tracks.

Refer to Figure 95

3. At each frame-mounted coulter to be adjusted, slightly loosen all six bolts ( , ) at the mount.

4. Using a rubber mallet, tap the spring bar up or

1 2

down until the bottom edge of the coulter disk is at ground level.

5. Tighten the two clamp bolts until both U-bolts are ﬁrmly against the edge of the spring bar . It is

normal for there to be a small gap between the clamps.

6. Tighten the four U-bolts .

7. Lower the drill to planting height and pull forward 30 feet (10 m).

8. Check coulter blade to opener blade (furrow centerline) alignment.

Frame-Mounted Coulter Height

Note: A gap of as much as1⁄8in (3 mm) between the

clamp plates is normal.

Frame-Mounted Coulter Force

Coulter springs are set to 400 pounds (181 kg). 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 adequate 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 96

1. Raise the drill and install transport locks. See “Lift /

Lower” on page 25.

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 93⁄4inches (24.8 cm), or longer than 101⁄4inches (26 cm), 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 wheels), resulting in uneven coulter depth and/or uneven seed depth. If high forces are required, frame weights are probably required.

Row Unit Shut-Off

To shut off seed ﬂow to individual rows, such as to operate with an alternate row spacing, there are two or three steps involved:

Refer to Figure 97

1. Block the seed ﬂow to the row with an optional seed tube plug. See page 163 for ordering.

2. Re-calculate the drill’s swath, and check for any changes needed to:

• marker extension (see pages 21 and 176) and

• calibration (step 15 on page 45).

3. On 10HD and 25 Series, reduce needless wear on the unused rows by locking them up. See page 105.

Seed Meter Setup and Adjustment

Your Drill was originally supplied with a speciﬁc seed meter type and internal components optimized for a particular crop. Depending on the meter type and conﬁguration, there may be adjustments available.

On 10HD and 25 Series openers, you can also entirely change the meter as your crop mix changes.

All models support:

• Great Plains Singulator Plus™ meters

The 3N4010HDP and 3N4025 further support:

• Finger pick-up meters.

The 3N-40P does not support feeder cups. Use a Singulator Plus™ meter with speciﬁc wheels for volumetric applications.

10HD, 25 Series Finger Meter Adjustments

Note: Applies only to 10HD and 25 Series openers.

The ﬁnger pick-up meter has an adjustable brush, and alternate inserts are available for the backing plate. The brush has been pre-set to the optimum setting for most seed sizes. The factory-installed insert is the “A” insert.

Optimum planting speed is 41⁄2to 5 miles per hour (7.2 to 8 kph). Excess speed causes poor spacing performance due to seed tube bounce, and may also cause improper depth control due to row unit bounce.

Always pay attention to your drill monitor. Compare actual seed usage to your estimates.

Fine-tune your drill by thoroughly checking all key components including: seed tubes, chains, sprockets, tire pressure, seed monitor, double disk openers, gauge wheels, seed ﬁrmer, closing wheels, parallel arms, and the row unit itself.

Finger Meter Brush Adjustment

The brush reduces or eliminates “doubles” (delivering two seeds per ﬁnger), but if set too aggressively can cause “skips” (delivering no seed on some ﬁngers). As needed, adjust for minimal doubles and skips.

Note: These instructions describe the current ﬁnger

pickup meter shipped with new Great Plains drills, with an integrated adjustment lever for the brush. If

you have added pre-existing ﬁnger meters after purchase, there is some chance that you may have

the previous model meter, adjusted by screwdriver rather than lever. If so, rely on counting detents to determine the setting. Not all have 9 detents.

Refer to Figure 107

The adjustable brush provides additional ﬂexibility to accommodate a wide range of seed sizes. Use lever (L) to gently rotate the brush into position.

Finger Meter Inserts

Refer to Figure 108

The backing plate is equipped with an “A” insert . In tests, this insert provides the best performance in most seed sizes. However, there are two alternative inserts that can be used. Before changing to a different insert, please consult with a Great Plains service representative for a recommendation.

The identiﬁcation of the insert type is molded into the back of the insert.

Meter Performance Risk:

Be cautious in using seed treatments, additives, and other chemicals when possible. They can cause meter performance problems and premature wear to meter parts.

Avoid the use of graphite with untreated seeds. If graphite must be used, use Precision®Planting graphite or Great Plains graphite which is less abrasive. Seeds with Maxi, Captan, Cruiser, Poncho and similar treatments can beneﬁt from graphite. Use the amount recommended on the graphite container, usually 1 tsp(5ml)/unit or 1 tsp/80,000 seeds.

Figure 108

Finger Meter Insert

Always store meters in a dry, secure place, with brush in between two meter ﬁngers. Moisture, temperature, nest-building insects and rodents can create problems.

Always pay attention to your seed monitor and operating manual. Monitor the amount of seed you are planting compared to your expectations. Always investigate abnormalities!

If you are planting:

• ﬁnger-metered,

• twin-row crops,

• at seed interval spacings above 61⁄2inches (16.5 cm), you can synchronize each pair of adjacent meters in a twin row so that you achieve the maximum seed-to-seed spacing between the units of the pair.

If you are planting:

- single-row,

- or with singulating meters,

- or a volumetric crop,

- or twin row with seed spacings below 61⁄2in (16.5 cm), this section of the manual, and the sprocket indexing charts, do not apply to your operations.

If the initial indexing does not provide equal spacing, see “Indexing Fine Adjustment” on page 87.

Refer to Figure 109

1. Find the chart for your row spacing, meter ﬁnger count and desired seed population. Note the “Tooth Number” value for the “Rear Meter” in the far right column.

2. Remove both meters of a row unit pair. Note that tooth 1 and many of the other teeth on the driven

sprockets , are stamped with a tooth number.

On front row unit:

3. Relax idlers on front meter drive by lifting the spring off the rear post .

4. Lift chain off driven sprocket , and rotate sprocket so that tooth 1 is as close as possible to straight up (TDC: top dead center, 12:00 position).

5. Re-engage chain and idlers, making sure chain is taut at top, and that sprocket tooth 1 has not shifted off TDC.

On rear row unit:

6. Relax idlers on rear meter drive by lifting the spring off the rear post .

7. Lift chain off driven sprocket , and rotate sprocket so that the tooth number called for in the chart is at TDC (or is the same as the front row sprocket).

8. Re-engage chain and idlers, making sure chain is taut at top, and that the designated sprocket tooth has not shifted off TDC.

9. Re-install meters. No particular wheel orientation is required during meter installation. The meter engagement is symmetrical, and the results identical no matter how the coupler captures the meter shaft.

Sprocket Indexing Charts

1. For: your 6- or 12-ﬁnger meter, and your twin row spacing (30in on this page) ﬁnd your seed rate in the Population column, or your seed spacing in the Seed Spacing column. Seed spacing is seed-to-seed within a single row of a twin row pair.

2. At the front/forward row unit of a pair, set the driven (ﬁnal) sprocket of the meter drive so that tooth stamped #1 is straight up (TDC, 12:00 position).

3. At the rear/trailing row unit of the pair, set the driven sprocket so that the tooth number at “Rear Meter” is in the straight up 12:00 position.

These charts are in U.S. customary units. See page 180 for metric charts (70cm twin row).

Not Rate or Spacing Charts:

These are NOT seed rate or seed spacing charts. These are for staggering seed spacing between the rows of a twin row.

Note: For adjusting spacing between rows of the pair,

Indexing Fine Adjustment

If, after indexing, the twin-row side-to-side seed stagger is substantially imbalanced, it is possible to make small adjustments that may correct it. Imbalance can occur over time as row unit chains wear and stretch.

The procedure is different for 6- and 12-ﬁnger meters.

If an adjustment is made, test it on one row pair before adjusting the entire planter.

Before making any Indexing Adjustments:

• Check actual planted seed spacing. Seed Spacing is found by measuring the distance between 25 correctly planted seeds in one row and dividing by 24. (A visible skip or double is counted as one seed.)

• Make sure the current front sprocket index is 1, and the current rear sprocket index number matches the number in the indexing chart for actual seed spacing being planted.

6-Finger Meter Stagger Adjustment

Find your current indexing value row in the chart on page 86.

Each (sprocket tooth) number directly above or below the current rear meter sprocket setting in the right most column of the seed indexing chart represents a small movement of the rear row seed relative to the front row seed.

Changing rear your sprocket to the next number up in the chart retards, moving each rear row seed back a small amount.

Changing rear sprocket to the next number down in the chart advances, moving each rear row seed ahead a small amount.

Example 1:

The 6 Finger, Twin Row 30in planting population is 32000 or 13.1in seed spacing. The chart setting for the rear sprocket is [ 15 ]. Each rear row seed should fall

6.6in behind the front row seed.

If each rear row seed measures only 5in behind the front row seed, reset the rear meter sprocket to the next number up in the chart [ 12 ]. This moves the rear seeds back to make the stagger closer to 6.6in.

Example 2:

The 6 Finger, Twin Row 30in planting population is 32000 or 13.1in seed spacing. The chart setting for the rear sprocket is [ 15 ]. Each rear row seed should fall

6.6in behind front row seed.

If each rear row seed measures 9in behind the front row seed, reset the rear meter sprocket to the next number down in the chart [ 18 ]. This moves the rear seeds ahead to make the stagger closer to 6.6in.

Unit-Mount Cleaner Adjustments

Refer to Figure 116 and Figure 117

Optional Martin row cleaners are unit-mounted, using: UMRC: Unit-Mount Row Cleaner (stand-alone), or UMC-RC: Unit-Mount Coulter RC (on coulter bracket, with or without a coulter disk present).

There are two adjustments:

1. Wheel placement (forward or aft mounting hole, for more or less aggressive cleaning), and

2. Wheel height, adjusted by a stop. Cleaner arms ﬂoat. The stop only sets the lowest position.

In UMRC mount, a pinned cross-tube on the mount adjusts the depth. In UMC-RC (coulter) mount, a sliding down-stop block adjusts how close to the ground the row cleaners operate.

The row cleaner needs to be adjusted for your conditions, crop changes, and as coulters and openers wear. Ideally, cleaners contact only the trash, and do not disturb the soil. If allowed to “dig”, row cleaners can reduce seed coverage.

Suggested initial depth is tine tips at ground level.

Make the adjustment with the drill raised. Install lift-assist cylinder locks. Also check bolt tightness prior to each planting session, to avoid down-stop slippage.

UMRC: Cleaner Adjust

Sharp Object Hazard:

Row cleaner tines, casting edges and coulter blades are sharp. Wear hand protection when working in this area.

Frame Weight

In challenging no-till conditions, some row-unit down-pressure settings (across all rows), and many frame-mounted coulter settings, may be high enough to lift the wing caster wheels off the ground. To avoid inconsistent results, add weight to the wings.

One or two pairs of (four total) weight brackets are optional. The weights required are common “suitcase” tractor weights, and are widely available, although not supplied by Great Plains.

Each bracket accepts up to ﬁve standard weights, about 500 lbs (227 kg) per wing, or 1000 lbs (454 kg) per kit.

Great Plains recommends loading no more than two sets of brackets, representing 2000 lbs (907 kg) total.

Do not add weight to the center section. It is always heavier than even a fully weighted wing, and never requires additional weights.

Available Down Force

Each Weight set assumed to be fully populated with ﬁve 100 pound weights.

Note: This table does not include the effect of adding

frame-mounted coulters to the drill.

Although frame-mounted coulters add 61 lbs (28 kg) to each row, they also rely on the available weight per row, and can easily require more weight than they contribute.

Although this reduces the weight available to the openers, the opener workload is also reduced by having the furrow prepared by the coulters.

10P Series Row Unit Adjustments

Refer to Figure 124 (which depicts a row unit fully populated with most optional accessories supported for use with the 3N-4010P drill)

From front to back, a Great Plains 10 Series row unit can include the following capabilities (some optional):

1. Dual Down Pressure Springs (Standard) Each row unit is mounted on the planter via parallel arms which allow the row unit to independently move up and down while remaining parallel to the ground. The adjustable spring provides the force to get the row unit and attachments into the soil.

2. Row Unit Spring Cam (Standard) This adjustment sets the down-force used by the row unit. See “10P Series Row Unit Down Pressure” on page 96.

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 “10 Series Disk Blade Adjustments” on page 97.

4. Shut-Off Cap (Standard) Disable rows for alternate row spacing. See “Row Unit Shut-Off” on page 79.

5. Singulating Seed Meter (Standard)

6. Seed delivery tube (Standard) No adjustments are necessary.

7. Disk Scraper (Optional) In sticky soils, a scraper helps keep the opener disks operating freely. An optional carbide scraper is available. See page 167.

8. Seed Firmer (Seed Flap Standard, not shown)

Keeton Improves seed-soil contact, and provides a stable arm for a low-rate liquid fertilizer delivery tube. See “10 Series Keeton® Adjustment” on page 98.

10P Series Row Unit Down Pressure

Refer to Figure 125

The ideal amount of down-force causes the press wheels to compress any loose surface soil, but not press a trench into subsoil.

To assess down-force, operate the drill for a short distance on typical ground (with or without seeding), and stop. Leave the drill lowered (row units in ground).

At several row units, inspect the furrow created by the opener discs and closed by the press wheels.

Note: Be sure to inspect rows both in and out of tire

tracks.

Refer to Figure 126

1. If the press wheels are leaving no tracks, or light tracks, increase down-force.

2. If the wheels are compressing trash and loose soil, and leaving clear tracks right at the top of the subsoil, down-force is probably correct and needs no adjustment.

3. If the wheels are creating a trench into the subsoil, down-force is too high and needs to be reduced.

Adjusting 10P Series Down Force

The springs allow the row units to ﬂoat down into depressions and up over obstructions.

On 10 Series row units, the seed trench is primarily opened by the coulters. Row unit springs provide only additional assistance needed to make a furrow “V” shaped and ensure furrow closure by the press wheels.

Often, the rows may be run at the minimum spring setting, other than in tire tracks, which commonly need some adjustment.

If trench depth is not being achieved across all rows, adjust the force and/or depth of the coulters before making row unit spring adjustments.

If you cannot achieve enough down force, adding a weight kit may help. See “Dual Weight Kit” on page 161.
