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 5, thor-
oughly.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.

Page 6
2 3N-4010F/3N-4010HDF/3N-4020F 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 hear-
ing 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 (30m)
of a freshwater source, nor at a car wash.
Store or dispose of unused chemicals as specified by chemi-
cal manufacturer.
Dispose of empty chemical containers properly. Laws gener-
ally 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.
196-359M Table of Contents Index 2013-10-29
Page 7
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 oper-
ations.

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 fold-
ing/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 driv-
ing on public roads.
Use lights and devices provided with drill.

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 trans-
port.
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 26 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 125.

Shutdown and Storage

Clean out and safely store or dispose of residual chemicals.
Secure drill using blocks and transport locks. Lower open-
ers 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.
OFF

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 mov-
ing parts.

Safety Decals

Safety Reflectors and Decals
Your drill comes equipped with all lights, safety reflectors and decals in place. They were designed to help you safely operate your drill.
Read and follow decal directions.
Keep lights in operating condition.
Keep all safety decals clean and legible.

This section will help you prepare your tractor and drill for use. Before using the drill in the field, you must hitch the drill to a suitable tractor and level the drill.

Pre-Setup Checklist

1. Read and understand “Important Safety Informa­tion” on page 1.
2. Check that all working parts are moving freely, bolts are tight, and cotter pins are spread.
3. Check that all grease fittings are in place and lubri­cated. See “Lubrication” on page 114.
4. Check that all safety decals and reflectors are cor­rectly located and legible. Replace if damaged. See “Safety Decals” on page 5.
5. Inflate tires to pressure recommended and tighten wheel bolts as specified. “Appendix” on page 125.

Hitching

There are three hitch options (see page 119). Check that the tractor and drill are compatible before hitching.
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 machines being hitched. Stop tractor engine and set park brake before installing hitch pins.
Refer to Figure 4
1. Use drill parking jack to raise or lower tongue as needed. Hitch drill to tractor using a hitch pin of ade-
quate strength - minimum diameter 11⁄2in (38mm).
2. Install a retaining clip on the hitch pin to prevent it from working up.
3. Securely attach drill safety chain to tractor drawbar.
4. Lower tongue onto tractor drawbar with jack. Remove jack and store on tongue.

Make Hydraulic Connections

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

Hydraulic Circuit Connections

Refer to Figure 5
Great Plains hydraulic hoses are 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.
To distinguish hoses on the same hydraulic circuit, refer to the symbol molded into the handle grip. Hoses with an extended-cylinder symbol feed cylinder base ends. Hoses with a retracted-cylinder symbol feed cylinder rod ends.
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.

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

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.
Route the power lead to a +12Vdc source. Route the harness to the hitch, allowing enough slack for hitch movement and any tractor articulation.
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 35.
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 39.
Figure 8
Veris Controller
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.

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), see “Bleeding Hydraulics” on page 105.
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 102.

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:
Kit: Manual
122-259K 122-262M (ordered separately) 198-960A 198-961M (included in kit)

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 107).
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 33). 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 175 through Figure 180 on pages 127 and 129
4. Check the measurement against the value recom­mended by Great Plains.

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 100.
Check the tires for proper inflation according to “Tire
Inflation Chart” on page 125.
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 126
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 17) 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.

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 2in coulter depth. See “Frame Height” on page 60 for adjustment.
Figure 18
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 3rd or 4th 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 sys-
1
tem
inch (13mm) to maintain levelness.
2
If implement is still not level after re-phasing, see “Bleed-
ing Lift Hydraulics” on page 105 and “Level Frame Side to Side” on page 102.

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 20
Figure 20
Fold: Drive/Lock Selector Valve
Pinch/Crush Risk: Drill Center section moves back while folding. Tractor may move forward. Allow at least 10ft (3m) clearance behind drill and ahead of tractor when folding.
21844
1. Set Drive/Lock selector valve to Lock.
2. Fold markers (Option). See page 33.
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 22.
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). Set circuit to Neutral. Do not Extend.

Note: There are two key points to remember when oper-
ating 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 unfolding drill.
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 23
1. Check selector valve set to Locks.

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 at the
bottom of this page for weights of various configurations.
2
(67%) of the
3
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 and observe 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 125.
Bystanders
Check that no one is in the way before moving. Do not allow any one to ride on the drill.
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 125.
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.

Loading Seed

To unload seed, see “Seed Cleanout” on page 101.
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 rec-
ommended 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 “Seed Cleanout” on page 101.
6. If not planting all rows, shut off unused rows. See
page 66.
7. Load seed. Load or spread materials evenly across
all partitions. Use a tool or gloved hand.
8. Make a note of the quantity loaded, for later confir-
mation of population or application density desired.
9. Close and secure the box lids.
WARNING
To avoid serious injury or death:
Watch your step when climbing ladder or walking on walkboard.

Planting

Seed Rate

Seed rate on this family of drills is controlled by:
• Seed rate handles.
• Seed cup door handles.
• Rate set by the hydraulic drive console.
Set Seed Rate Handle
Refer to Figure 27
There are main box seed rate handles for each section of the drill (3 handles total). All must be set identically.
The seed rate handle controls the percent engagement of the seed sprocket in the seed cups. The setting of the handle is given by the chart on page 40. These settings have been chosen based on the seed size, and a coarse rate that allows the hydraulic drive to provide optimal fine rate control. Once set, the handles are not adjusted.
To set a handle:
6
1. Loosen wing nut under handle.
2. Consult the chart on page 40 for your seed and rate range. Note the Rate Handle setting provided.
6
7
3. Move indicator to a scale value about 10 higher than the setting from the chart. Then move handle back to the chart setting.
4. Tighten wing nut.
Set Seed Cup Door
Refer to Figure 28, which depicts the seed cup door handle in position .
At each seed tube, adjust the seed cup door handle for the seed size.
The handle has three normal operating position detents:
(top detent) is for the smallest seeds.
1
Use it for wheat and similar small seeds. (middle detent) is for larger seeds.
2
Use it for soybeans and similar larger seeds. (bottom detent) is for oversize or fragile seeds.
3
If you experience excessive cracking with setting , use setting .
Note: Handle position is used for clean-out (page 101),

About Hydraulic Drive Rate
Before it can control seed rate, the console must be:
• configured with information about your drill and intended planting speed,
• configured with a calibration number for the seed and rate range, and;
• calibrated to fine-tune the calibration number and speed.
This process is described starting on page 39.
Refer to Figure 29
With those steps completed, field seeding rate is con­trolled manually by adjusting the target “set=” rate using the / arrow buttons. Field 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

Seeding Depth

Refer to Figure 29
Seeding depth is controlled by coulter depth in front, and press-wheel height in back. Seed cannot be
placed any deeper than coulter depth. Before adjusting row units, make sure coulters are performing as desired.
See “Level Frame Side to Side” on page 102. See “Level Frame Front to Rear” on page 102. See “Frame-Mounted Coulters” on page 63. See “10 Series Opener Depth” on page 74.
Consistent seeding depth relies on appropriate down-pressure for conditions.
See “Frame Weight” on page 68. See “10 Series Row Unit Down Pressure” on page 71.
For information on opener adjustments, see one of:
10 Series Row Unit Adjustments” on page 70 “10HD Series Row Unit Adjustments” on page 75
20 Series Row-Unit Adjustments” on page 84 For information on troubleshooting opener problems, see “Troubleshooting” on page 90.

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 92.
Refer to Figure 31
Note: The Pump switch has no function on 3N-40
drills configured byGreat Plains. Unless connected to field-installed equipment, leave it off.
P

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.

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

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 hoses 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 39.

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. Look for evidence of unexpected unevenness in the seed level. There may be mounds at any blocked rows.
Seed consumption is uneven, and end rows run out before mid-section rows. Re-load seed when the level indicators near Empty.
Figure 32
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 an 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 fa below the limits set by EN 61010-1: 1993\A2: 1995 - Chapte
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.
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 107.
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 exces-
sive folding speed may damage markers, adjust markers to a safe folding speed according to “Marker Speed” on page 107.
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.

Shaft Monitor Operation (Option)

Refer to Figure 33
To operate the optional shaft monitor, turn the system on via the ON-OFF switch.
During normal movement, the indicator lamps for each section are on steady, indicating that shaft rotation is detected.
If the seed-cup shaft stops for 30 seconds or more, an alarm sounds and the lamp for the affected section
flashes.
The 30-second delay is to prevent nuisance alarms when turning at the end of passes.
If a shaft failure does occur, remember that you have traveled for 30 seconds without planting under the affected section.
For installation, see: “Shaft Monitor (Option)” on page 18.
For ordering information, see: “Shaft Monitor” on page 121.

Basic Operation

Power Up

Refer to Figure 36
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 54).
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.

Hydraulic Drive Field Operations

Refer to Figure 37
1. Turn on Controller Console by pressing the ON/VR button. Green light above ON/VR button illuminates when power is on.
Pressing the ON/VR button twice puts the unit in VR mode. VR appears on the screen along with the Rate from the recipe or sent from your GPS. Press ON/VR button again to toggle back to manual mode. (Mode and rate changes take effect with the release of the button.)
2. To change rates manually whether in Manual or in VR mode, simply touch the
/ arrow buttons. This
changes the Controller to the rate you select manu­ally. To return to VR, simply touch the ON/VR button to toggle back to VR mode.
3. Before planting, conduct a seed rate Calibration (page 39) and ground speed Calibration (page 51).
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 trac-
Figure 37
VR (Variable Rate) Mode
tor 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 auto-
matic 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.
28273
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 one
cally 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).

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
1
least
lb (0.1 kg), and requires at least 100 sec-
4
onds. 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.

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.

Prime Seed Meters
Before running an actual calibration, it is important that the seed cups be filled with seeds, and the flutes primed to deliver seed at first rotation. Step 19 through step 30 executes a short calibration to do this.
If the cups are already primed, skip to step 31.
Refer to Figure 48

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-4010F, 3N-4010HDF and 3N-4020F 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 102
• coulter depth setting - see “Frame-Mounted
Coulters” on page 63
• coulter mount adjustment - see “Individual
Frame-Mounted Coulter Depth” on page 65
• coulter down-force spring setting - see “Frame

• press-wheel height setting - see:
10 Series Opener Depth” on page 74 “10HD Press Wheel Adjustments” on page 82 “20 Series Press Wheels” on page 89

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-4010HDF accepts either FMC or unit-mount coulters (UMC), although only one type of coulter can be installed simultaneously.
For adjustments:
Refer to Figure 86
1. Frame-Mounted Coulters (FMC) frame height information begins on page 63.
2. Unit-Mounted Coulters (UMC, 10HDF only) frame height information begins on page 76.
3. No Coulters use the same frame height setup as UMC, page 76.

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 76.
If the drill has frame-mounted coulters, use the height procedure on page 63.
Refer to Figure 87
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.
Conditions Unit

For no-till conditions, a 26in (66cm) 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 26in (66cm) helps keep the no-till spring forces from burying the openers.
Note: Setting the frame above the 26in (66cm) limits the
opener downward flotation.
Note: Running with the frame below 26in (66cm) 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 101.
Refer to Figure 88
The lift system includes an adjustable stop valve to fix
1
the height of the opener frame when the drill is lowered.
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
2 3
3 4
(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 about
1
in (3mm), repeat the
8
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.

The factory configuration of frame-mounted coulters (FMC) is that they run about 1in (2.5cm) 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 89

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 65.
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 66.

seeding depth.
For example, if
8
the desired seeding depth is 1in (2.5cm), set
7
the coulters to run at 2in (5.1cm) 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 1in (2.5cm) below seeding depth , or even ing 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 101.
Refer to Figure 91
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

drill stops consistently at the new height.
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 92

Frame-Mounted Coulter Force

Coulter springs are set to 400 lbs (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 93
1. Raise the drill and install transport locks. See “Lift /
Lower” on page 22.

2. Determine the new spring length desired. See 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 94
1. Block the seed flow to the row with an optional seed
tube plug. See page 121 for ordering.
2. Re-calculate the drill’s swath, and check for any
changes needed to:
• marker extension (see pages 18 and 127) and
• calibration (step 16 on page 43).
3. On 10HD Series, reduce needless wear on the
unused rows by locking them up. See page 80.

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.

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.

10 Series Row Unit Down Pressure

Refer to Figure 102
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 103
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 10 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 120.

To adjust down pressure, use the spring adjustment tool (part 198-126H) stored behind the tool bar at the Slow-Moving-Vehicle placard.
1. Raise the drill. Although this adjustment can be made with the drill lowered, the springs will be in ten­sion, and will require more effort. The extra force required may also damage tools.
2. Put tractor in Park and shut it off.
3. Position tool in the holes.
4. Pull upper spring link back.
5. Move the adjustment cam to the new setting on the spring adjust bar.
Note: Do not set all rows higher than notch two. Using
high settings across all rows causes uneven plant­ing. Individual rows may be set higher if running in tire tracks.

10 Series Disk Blade Adjustments

Opener disc angle and stagger is not adjustable, but disc-to-disc spacing is, and may need attention as discs experience normal wear. Spacers will need to be reset when blades are replaced.
Refer to Figure 106
The ideal spacing causes the blades to be in contact for about one inch. If you insert two pieces of paper between the blades, the gap between them should be 0.5 to
1.75in (13 to 44mm).
If the contact region is significantly larger or smaller (or there is no contact at all), it needs to be adjusted by mov­ing one or more spacer washers. If the contact region varies with blade rotation, one or both blades is likely bent and in need of replacement.

Unit-Mounted Coulter Adjustments

Unit-mounted coulters (UMC) are an optional alternative to frame-mounted coulters. Only one type of coulter may be installed. See page 122 for ordering information.
Note: Unit-Mount Coulters are not factory-installed.
Check alignment and depth prior to first use.
10HD Coulter Depth Adjustment
Check frame height before making any UMC adjust­ments. See “Frame Height without Frame-Mounted Coulters” on page 61.
The ideal operating depth for unit-mounted coulters is
1
in above opener depth. Although they may have origi-
4
nally been set to this depth, coulter (and opener) blades wear with time, and may need adjusting.
Adjusting the coulter depth is accomplished by re-mount­ing the coulter blade in one of the six mounting holes arranged in a staggered pattern in the coulter bracket.
Refer to Figure 112 and Figure 113

10HD Coulter Row Alignment
Refer to Figure 114
For both frame- and unit-mounted coulters, the ideal alignment is for the blade to prepare a furrow directly ahead of the opener discs.
As a check on coarse alignment, sight along the coulter blade centerline , the gap between the opener blades
2 3
, and the centerline between the press wheels . If they are clearly out of alignment, either the coulter or the press wheels (or both) may be in need of adjustment.
The exacting test of correct alignment is field results. Operate the drill on some test ground (no seed required), and verify that the opener blades are in the groove opened by the coulter.

Refer to Figure 115
To adjust unit-mounted coulter alignment, loosen the four

bolts that attach its bracket to the row unit. The holes on the row unit are slotted, side-to-side, and allow the coulter bracket sideways and rotational adjustment.
Keep the coulter blade vertical while adjusting.
If the blade cannot be brought into alignment, check that the blade spindle itself is using the same hole location on each side of the bracket.

10HD Row Unit Down Pressure

Refer to Figure 102
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.
Inspect Furrow Here
{
Refer to Figure 103
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 10HD Row Unit Down Force
The springs allow the row units to float down into depres­sions and up over obstructions.
With Frame-Mounted Coulters
With frame-mounted coulters, 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.
With Unit-Mounted Coulters (or no coulters)
Without frame-mounted coulters, the row unit springs provide the primary down force for cutting through resi­due and opening the seed trench.

Row Unit Down Pressure

10HDP Series Down-Pressure
Refer to Figure 118
An adjuster cam sets row unit spring down pressure individually for each row unit. This is useful for penetrating hard soil and planting in tire tracks.
The notes in the left table below are based on a drill without coulters. About 120 pounds (54 kg) of the down-force is the weight of the row unit itself. The additional force is due to the springs lifting against the mass of the drill.
Test, without seeding, in your conditions, to determine optimal down-force settings.
To adjust down pressure, use an adjustable or open-end 11⁄8inch (29 mm) wrench.
1. Raise the drill. Although this adjustment can be made with the drill lowered, the springs will be in tension, and will require more effort. The extra force required may also damage tools.
2. Put tractor in Park and shut it off.
3. Position wrench on hex nut weldment.
4. Pull upper spring link back.
5. Move the adjustment cam to the new setting on the spring adjust bar.

10HD Row Unit Lock-Up
When seeding is shut off, individual row 10HD Series row units can be locked up to reduce wear. The opener
shank has a hole in the opener shank that accepts an optional pin to block parallel arm movement. See
page 122 for pin ordering information.
1. Raise the drill. Although this adjustment can be made with the drill lowered, the springs will be in ten­sion, and will require more effort. The extra force may also damage tools.
2. Set the down pressure springs to the minimum cam

setting, per the instructions on page 71.
Crushing and Sharp Object Hazard: Do not attempt to lift the row unit by hand. The weight of the unit, plus the force of the springs (even at minimum) is too great (plus, a free hand is needed for pin insertion). Even with multiple people lifting, hand-lifting is unsafe - there are numerous sharp edges, and the row unit will snap down violently if a grip is lost.

10HD Disk Blade Adjustments

See also “10HD Opener Maintenance” on page 112.
Opener disc angle and stagger is not adjustable, but disc-to-disc spacing is, and may need attention as discs experience normal wear. Spacers will need to be reset when blades are replaced.
Refer to Figure 106
The ideal spacing causes the blades to be in contact for about one inch. If you insert two pieces of notebook paper between the blades, the gap between them should be 0.5 to 1.75in (13 to 44mm).
If the contact region is significantly larger or smaller (or there is no contact at all), it needs to be adjusted by mov­ing one or more spacer washers. If the contact region varies with blade rotation, one or both blades is likely bent and in need of replacement.
Pinch/Crush Hazard and Machine Damage Risk: Raising a row unit on a block by lowering the drill is risky. Full lowering can easily damage components, and hydraulic failure is a safety hazard.
Machine Damage Risk: Do not pin the row unit while it is in the lowered position. If the pin is inserted below the parallel arm, unit damage will occur when planting begins.

10HD Press Wheel Adjustments

Opener Depth (Press Wheel Height)
Seeding depth on 3N-4010F, 3N-4010HDF and 3N-4020F is set by frame-mounted coulter depth (if installed) and row unit depth. Set frame height (page 63) before making row unit depth adjustments.
10HD Series press wheel height is a stop adjustment and not a spring adjustment. It establishes a fixed rela­tionship between opener depth and the closed-furrow surface at the press wheel
Refer to Figure 110
Set opener seeding depth by adjusting press-wheel height . To adjust, first raise openers slightly, then lift and slide T handles on top of openers. Initially adjust
all press wheels to the same height. Individual rows run­ning in tire tracks may need to be set deepera.
• For more shallow seeding, slide T handles forward
• For deeper seeding, slide T handles backward
If press wheels are lifting off ground, check front-to-back level, and increase row unit spring down force.
If press wheels are digging into ground, reduce spring down force at the row units.

20 Series Row-Unit Adjustments

Refer to Figure 126, which depicts a 20 Series row unit fully populated with all features supported on 3N-4020F drill (ex­cepting Seed-Lok). From front to back, they are:
1. Dual Down-Pressure Springs & Cam (standard) See “20 Series Row-Unit Down Pressure” on page 85. Each row-unit is mounted on the planter with parallel arms. This parallel-action mounting allows the row-unit to move up and down while stay-
ing horizontal. A cam adjusts the force between 100 and 225 pounds.
2. Double Disk Openers (standard) A pair of canted opener disk blades open a furrow
and keep it clear for the seed tube. These disks are adjustable for contact. See “20 Series Row-Unit Down Pressure” on page 85.
3. Side Depth Gauge Wheels (standard) These wheels are the primary control of seeding
depth (set by the T-handle). They also have adjust­ments for angle and disk contact. See “Side Gauge Wheel Adjustments” on page 86.
4. Seed Tube (standard) A seed tube mounted between the disks (not shown) delivers seed to the trench. It is fed by the seed
meter, and has a seed flap , shown here cut back for clearance from the seed firmer. See “20 Series Seed Firmer Adjustments” on page 88.
5. T-Handle (standard) This handle sets the height of the side depth
gauge wheels. See “20 Series Row-Unit Planting Depth” on page 85.
6. Seed Firmer (optional) An optional seed firmer (Keeton shown) minimizes seed bounce and improves soil contact. See “20 Series Seed Firmer Adjustments” on page 88.
7. Press Wheels (standard) The press wheels close the furrow, gently pressing the soil over the seed to ensure good seed to soil contact for even emergence. They have adjustments for down-pressure, stagger and angles. See “20 Series Press Wheels” on page 89.

Hydraulic Drive Troubleshooting

Drive will not rotate:
(see Troubleshooting Flow Chart and Electronics Over­view, page 96 and page 97)
1. Check cab console:
196-359M Table of Contents Index 2013-10-29
a. No power to cab console - check with voltmeter.
b. Upper line (set) is visible but no lower line (out
rate and speed) on display: move to Communi­cation troubleshooting below.
Page 97
Great Plains Manufacturing, Inc. Table of Contents Index Troubleshooting 93
c. 1 or 10 amp fuse on power cable may be blown.
d. Engage button is not on - check to see if green
indicator light is on.
e. Use Cab Console Power Tester (p/n 27857) to
check power out of cab console. Install tester on round 7-pin power/comm cable from cab con­sole. Turn drive on. Green LED shows power to external controller. Red LED shows power to solenoid. If LED lights are not lit, double-check power and connections; replace cab console if needed.
2. Check communication between cab console and
drive:
a. Check to see if power and communication cable
(main harness) is properly connected.
b. If no lower line on cab console appears (speed
and output rate), and drive will not rotate in cali­bration mode, use Cable Continuity Tester (p/n
27859) to test power and communication to external controller.
weather-pak solenoid connector from external controller. With tractor engine off, start drive cali­bration function. Auditory alarm should buzz for
1.5 seconds when drive is engaged in calibration mode. If no alarm, relay or external controller may need replacing. Call Service Department.
4. Check hydraulics:
a. Check hydraulic lever is in detent position.
b. Hydraulic lever is in wrong detent direction - a
check valve at outlet of motor prevents reverse rotation.
c. Make sure that both hoses are properly con-
nected to tractor remotes.
d. Inadequate system pressure. Gauge pressure at
filter and check reading. If system pressure is below tractor specifications, check system.
e. Power solenoid directly:
Rapid drive rotation may occur causing serious injury.
i. Disengage hydraulics.
ii. Reduce flow to 30-50%.
TO PREVENT DAMAGE TO COMPONENTS, DISCONNECT POWER/COM CABLE FROM CAB CONSOLE AND EXTER­NAL CONTROLLER BEFORE INSTALLING THIS TESTER.
Install 4-pin test plug on end of 4-pin power/comm cable before powering the Cable Continuity Tester - remove before reattaching power/comm cable directly to cab console.
c. If Cable Continuity Tester shows power is getting
to external controller, turn power off and remove Cable Continuity Tester and 4-pin test plug from ends of power/comm cable. Reattach power/comm cable to cab console and external controller.
d. If power/comm cable tester shows power and
communication is reaching external controller from cab console, and no lower line appears on cab console, replace chip or external controller. Call Service Department.
e. If Cable Continuity Tester (p/n 27859) isn’t avail-
able, check cable with voltmeter at connection at control module.
3. Test Relay inside external controller:
a. Use Relay Output Tester (p/n 27860) to test relay
inside external controller. Install tester to
iii. Power solenoid directly by connecting power
weather-pak connector to solenoid weather-pak connector. If drive doesn’t rotate, Proportional Coil (p/n 19799) may be defective. Check continuity with meter, or energize with 12v power and check for mag­netic pull with small screwdriver. Dou­ble-check connections on solenoid cable. If solenoid energizes but drive does not rotate when powered directly, tractor hydraulics are not properly engaged.
f. Excessive torque in drive system. Disconnect
main drive chain to check for rotation under zero load. Check for a problem with the mechanical portion of drive, such as foreign material or swelled grain wedged in meters, frozen bear­ings, misaligned chains. Install pressure gauge at motor inlet. Pressure should be 1000-1500 psi. If pressure is above 2000 psi, significant torque problems are present.
5. Check Speed signal (if drive rotates in calibration mode but not when planting)
Rapid drive rotation may occur causing serious injury.
a. No signal from speed sensor - check connection
at sensor and at drive controller.

b. Use Speed Simulator (p/n 27858) to trouble-
shoot speed loop. Leave tractor stationary and drive hydraulics do not need to be engaged.
c. Test speed sensor and hall effect sensor;
replace sensor if simulated speed appears on cab console.
d. Test speed cable between speed sensor and hall
effect module; replace cable if simulated speed appears on cab console.
e. Test hall effect module and cable to external con-
troller; replace module and cable if simulated speed appears on cab console. If speed does not appear, external controller or chip may need replacement. Call Service Department.
Drive rotates but not at desired speed:
6. Drive (out rate) fluctuating erratically:
a. If indicated field speed on drive is also fluctuat-
ing erratically, troubleshoot speed signal loop.
b. If field speed is steady, check for loose set
screws on motor encoder, contamination of pro­portional valve, or mechanical binding of chains.
7. Indicated speed fluctuating erratically:
a. Use speed simulator to troubleshoot speed loop.
Leave tractor stationary and drive hydraulics do not need to be engaged. If steady speed between 4-10 mph appears on cab console using speed simulator, troubleshoot radar and hall effect module. If steady speed does not appear, external controller may need replace­ment. Call Service Department.
b. Check radar gun angle.
c. Check power to system. Less than 12 Vdc power
will cause drive to behave erratically - often prob­lem manifests itself in speed loop.
8. Drive shuts off while planting:
a. If it occurs after 20 seconds of not planting, such
as turning on headlands, operation is normal safety shutoff (on units with radar speed signal).
b. Check setting of speed signal interrupter switch -
reposition as necessary to keep actuator from disengaging while planting.
c. 1.5 second delay shutting off drive - causes:
chain binding, inadequate hydraulics.
9. Drive will not achieve desired rate:
a. Recheck calibration number and rerun calibra-
tion procedure if necessary.
b. Check to make sure that your desired rate is
within the range of the meter that is installed.
c. Inadequate hydraulic flow. Adjust flow control to
higher position. Check with flow meter if flow is suspect.
d. Field speed too high. Check maximum planting
rate in seed chart for rate that you are planting.
e. Check speed shown on cab console against
other speedometer - tractor, planter monitor. If drive speed is significantly lower, recalibrate speed on drive.
10. Drive plants significantly higher than desired rate:
a. Recheck calibration number and re-run calibra-
tion procedure if necessary.
b. Check speed shown on cab console against
other speedometer. If drive speed is significantly higher, recalibrate speed on drive.
11. Drive continues to rotate after tractor has stopped:
a. Contamination or wear in proportional valve (p/n
19798). Remove and inspect. Blow out with compressed air. Check o-rings and reinstall. Replace if necessary.
12. Fluid weeping from motor shaft seal:
a. Excessive back pressure in return hose. Check
quick coupler connection. Use motor control port for return if available.

Calibration Troubleshooting:

If the time to run for calibration is less than 4 seconds, the cab console will display TIME TOO LOW.
Pressing the FUNCTION button will bring up the ENTER TARGET AMOUNT screen. The target should be raised to increase the calibration time. If the time is greater than 255 seconds, the cab console will display TIME TOO HIGH. Pressing the FUNCTION button will bring up the ENTER TARGET AMOUNT screen. The target should be lowered to decrease the calibration time.
If modest adjustments to the sample size continue to result in HIGH/LOW errors, chances are some other parameter is zero or incorrect by a large factor (such as decimal place error). To start over, press OFF, and then ON.
While rate calibration is running, one of four error mes­sages may be displayed:
Message Cause Solution
COMM TIMEOUT
TIME OVER LIMIT
USER TERMINATED
CALIBRATE ERROR
Power to or com­munication with the external con­troller was inter­rupted during calibration.
The external con­troller module ran too long in calibra­tion.
The ENGAGE but­ton was pressed during calibration.
The drive did not turn when calibra­tion began.
Check power and communica­tion connections from the cab console to the external control­ler and rerun cal­ibration.
Rerun calibra­tion. If the same message appears, call technical sup­port.
Rerun calibra­tion.
Check encoder cable and con­nection, solenoid cable and con­nection, and hydraulic lever position.
