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.
Be Familiar with Safety Decals
▲ Read and understand “Safety Decals” on page 6, thor-
oughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
2014-02-11 Table of Contents Index 195-068M
Page 6
2 3S-3000HD Table of Contents Index Great Plains Manufacturing, Inc.
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.
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.
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 the drill.
195-068M Table of Contents Index 2014-02-11
Page 7
Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
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.
▲ 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.
▲ Follow your tractor manual recommendations for maximum
hitch loads. Insufficient weight on tractor steering wheels
will result in loss of control.
▲ 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 96.
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/unloading and
marker operations.
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 gen-
erally require power rinsing or rinsing three times, followed
by perforation of the container to prevent re-use.
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 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 opera-
tion.

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.
▲ Watch out for wires, trees, etc., when folding and raising
drill. Make sure all persons are clear of working area.

Description of Unit
The 3S-3000HD is a towed seeding implement. This
three section drill has a working width of 30 feet (9.1m).
The drill has straight arm, double disk heavy duty
openers. The opener disks make a seed bed, and seed
tubes mounted between the disks place seed in the
furrow. Press wheels following the opener disks close the
furrow and gauge opener seeding depth. A T-handle on
the opener body is for seeding depth adjustments.
Seeding rates are adjustable with the seed rate
adjustment handle and sprocket changes.
The 3S-3000HD features active hydraulic down pressure
on the opener frames. When used on a tractor with
closed-center hydraulics, constant down pressure
ensures even opener penetration in uneven ground.
Hydraulic down pressure is adjustable at a single point.
Intended Usage
Use this implement to seed production-agriculture crops
in conventional or minimum tillage applications.

Preparation and Setup
This section helps 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 also setup 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 83.
4. Check that all safety decals and reflectors are correctly located and legible. Replace if damaged. See
“Safety Decals” on page 6.
5. Inflate tires to pressure recommended and tighten
wheel bolts as specified. “Appendix A - Reference
Information” on page 96.
6. Complete any initial setup items from “Appendix B -
Initial Setup” on page 105.
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.
Transport Hazard:
This drill can have positive and negative tongue weight, which
can work the hitch pin loose during transport. To avoid serious
injury or death due to a road accident, always use a clevis
hitch or clevis drawbar with a locking-style hitch pin.
Choose a drill-hitch option (page 91) that is compatible
with your tractor drawbar.
The 3S-3000HD has three hitch options:
• a clevis hitch,
• a small-hole, single-strap hitch or;
• a large-hole, single-strap hitch.
Use the clevis hitch with tractors that have single-tang
drawbars. Use the single-strap hitch for tractors with
clevis drawbars. Always use a locking-style hitch pin
sized to match the holes in the hitch and drawbar.

Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin, causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs,
seek immediate medical attention from a physician familiar
with this type of injury.

Setting the Bypass Valve
Refer to Figure 12
A bypass valve is plumbed into the opener down
pressure circuit. Tractors with load-sensing,
closed-center hydraulics require this bypass valve to
protect the tractor hydraulic system.
If you are unsure what type of hydraulic system is on
your tractor, contact your tractor manufacturer.
Turn the locking disc counter-clockwise to enable
adjustment.
Turn the adjustment knob counter-clockwise to
increase flow.
Turn the adjustment knob clockwise to decrease flow.
Turning it fully clockwise stops all bypass flow.

Machine Damage Risk: Failure to use the bypass valve on
load-sensing tractors may cause major tractor damage.
1. Release locking disc. Initially close bypass valve for
no oil flow by turning knob on valve clockwise completely.
2. With tractor at half throttle, adjust flow-control valve
on tractor so openers raise and lower at a reasonable speed. Keep tractor at one-half throttle for
remaining steps.
Note: The faster openers raise and lower, the greater po-
tential for oil heating, premature wear or tractor
damage.
3. Engage tractor hydraulics and lower openers. Lock
hydraulic lever on tractor for continuous operation.
See “Raising and Lowering Openers” on page 23.

(See also note below.)
6. Re-adjust pressure-control valves on drill to desired
opener down pressure as explained under See
“Opener Frame Down-Force” on page 50.
Note: The higher the bypass pressure, the greater the po-
tential for oil heating and premature tractor damage. At the same time, for proper opener operation
the bypass valve must be set at least 300 psi above
the opener down-pressure setting when the tractor
is at one-half throttle. Therefore, you should set the
bypass valve as low as possible while staying at
least 300 psi above the opener down pressure set-
FigureSpacer

ting.
While 2100 psi is a good starting point for setting the
bypass valve, if you consistently operate the drill with low
opener down pressure you can set the bypass valve
below 2100 psi. If you consistently operate the drill with
very high opener down pressure, you may need a
bypass-valve setting above 2100 psi.

Operating Instructions
This section covers general operating procedures. It
assumes that setup items have been completed for both
drill and tractor.
Experience, machine familiarity and the following
information will lead to efficient operation and good
working habits. Always operate farm machinery with
safety in mind.
General Description
On the standard 3S-3000HD, field operations are
controlled by tractor cab hydraulic levers. When openers
are lowered, mechanical clutches engage, and the
gauge wheels drive the seed meter shafts. Markers, if
installed, are on a separate circuit.
If the Point Row Option is installed, openers are
controlled by section, and are raised and lowered by
solenoid valves operated by the point row controller.
Seed meters operate at a rate proportional to ground
speed, as set by Drive Type and Seed Rate Handles,
based on the Seed Rate charts, and calibration.
Seeding depth and furrow coverage are controlled by drill
down pressure and row unit setup.

Pre-Start Checklist
❑ Lubricate the drill as indicated under Lubrication,
“Maintenance and Lubrication” on page 66.
❑ Check the tires for proper inflation according to “Tire
Inflation Chart” on page 98.
❑ 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 97
Raising and Lowering Openers
Opener sub-frames are on a dedicated hydraulic circuit.
Openers raise and lower independently of the drill frame
(which is raised and lowered by the transport lift circuit).
When lowered, the opener circuit can use live hydraulic
power to regulate down-pressure. To operate with live
hydraulic power, connect the opener lift circuit to the #1
remote hydraulic circuit or the circuit designed for
HYDRAULIC MOTOR control. On many CLOSED
CENTER or PRESSURE/FLOW COMPENSATED
tractors the #1 circuit is the circuit designed to supply live
hydraulic power to remote locations.
On the standard 3S-3000HD drill, the openers raise and
lower as a group, from a tractor cab lever. If the Point
Row Option is installed, each section can raise and lower
independently, using switches on the point row control
module in the tractor cab.
If the Two Outlet conversion kit is installed, a selector
valve near the hitch must be operated to switch between
Opener Lift and Transport Lift. During field operations,
this valve is in the Opener Lift position.
Crushing Hazard:
Raising openers on unfolded, unhitched drill will cause dril
tongue to rise suddenly, which could cause serious injury o
death. Be certain that drill is hitched securely to your tracto
drawbar and the safety chain is securely attached to tracto
before raising openers and unfolding drill.
Opener Lock Up
The openers must be locked up for transporting or for
working under the drill.
Refer to Figure 14
Each opener lift assembly has wire rod lock handle ,
and a cylinder lock status indicator on the lock hook.
Note: Opener transport lock handles can be moved

Note: The opener transport lock handles are spring load-
ed and can be moved to ROAD position with openers up or down, but locks only engage when
openers are completely raised. There are two locks
on each drill section.
4. Make sure transport lift cylinders and front box lift
cylinder are completely retracted (drill is lowered,
although openers are raised).
5. Slowly supply oil to rod (retract) end of fold circuit.
Completely fold wing frames until both wing gauge
wheels contact tongue tube.
Fold (for transport) is not complete until Transport Lift is
completed. In particular, the transport hooks only
engage, lift and secure the wings as part of Transport Lift
(the next topic).
Refer to Figure 17
6. Allow transport lift cylinders to settle back against
lock channels.
7. Before transporting, check that hydraulic cylinders
are holding lock channels securely.
Raising Drill (Transport Lift)
Transport Lift is on a dedicated hydraulic circuit. The
center main frame raises and lowers independently of
the opener sub-frames (which are raised and lowered by
the Opener Lift circuit).
The Transport Lift circuit also includes a cylinder for the
Transport Hooks, which lifts and restrains the
outer/forward ends of the wing sections when folded.
Transport Lift is normally used only after the drill is
folded. Opener Lift, and not Transport Lift, is used for
headland turns in field operations.
Note: If the drill is unfolded, gauge wheels do not lift off
the ground during Transport Lift. The wing sections
pivot, and the gauge wheels remain on the ground.
As they do not caster, they can drag sideways if
Transport Lift is used before fold.

3. Supply oil to the base (extend) ends of the Transport
Lift cylinders.
Refer to Figure 18
4. Leave the circuit extended until mainframe lift is
complete, the transport hooks have engaged, the
wing ends are lifted off the ground, and the front box
lift cylinder is fully extended.
Refer to Figure 19
5. Swing the locks up and onto the transport lift cylinders. They are temporarily held in place with polymer
bumpers. They are firmly held in place when the cylinder is relaxed in step 7.
6. Rotate cylinder lock channel over rod on front box lift
cylinder.
Note: Bumpers hold the transport lift cylinder lock chan-
nels in place temporarily. The channels will remain
in position when cylinders settle against channels.
7. Slowly reverse the Transport Lift circuit lever until all
three lock channels are resting firmly on the rod
ends of the transport lift and box lift cylinders. Set circuit lever to off.
The drill is now ready for the pre-transport checklist. See
“Transport” on page 26.

Loss of Control Hazard:
Towing the drill at high speeds or with a vehicle that is not
heavy enough could lead to loss of vehicle control. Loss of
vehicle control could 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, when fully loaded, weighs more than
1.5 times the weight of the towing vehicle.

Opener Operation
Crushing Hazard:
You will be seriously injured or killed if you are caught
between raising openers and drill frame. Always stop tractor
engine, set park bake, and remove key before adjusting or servicing openers. Keep all bystanders well away during drill
operation.
The openers are raised and lowered on their own
hydraulic circuit. When used with an active hydraulic
system, constant hydraulic down pressure is placed on
openers for even soil penetration across the drill. To
operate openers with live hydraulic power, always
connect the opener-lift hoses to the circuit designated for
hydraulic-motor control.
To achieve proper opener flotation, the opener hydraulic
circuit must be powered by an active hydraulic system.
An active hydraulic system requires a tractor with
closed-center hydraulics or pressure-flow compensated
hydraulics powered by a variable displacement hydraulic
pump.
To run drill on tractors with open-center hydraulics or on
tractors with fixed-displacement hydraulic pumps, you
must install a Great Plains kit, part number 194-143A.
Contact your Great Plains dealer for ordering
information.
If you are not familiar with your tractor’s hydraulics,
consult your tractor dealer.
For more information on opener adjustments, see
“Troubleshooting” on page 63.
High Pressure Fluid Hazard:
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.

Active Hydraulic Systems
1. Lock hydraulic lever forward during field operation for
constant hydraulic flow to openers.
John Deere tractors with Sound-Gard® Body:
Use lever lock clip, John Deere part number R52667,
to lock lever forward. See your tractor dealer for clip
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 hydraulic-system details.
Other tractors: Lock lever forward in detent position.
You may need to turn up 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 to openers.
Refer to Figure 25

pressure gauge and dial in desired pressure on
openers. There is one pressure-control valve for
openers on center section and one for openers on
wing sections of drill.
Note: Rotate knob clockwise to increase pressure and
counterclockwise to decrease pressure.
Machine Damage Risk:
Tractors with load-sensing hydraulics must use the bypass
valve to operate the 3S-3000HD. Failure to use the bypass
valve can cause major tractor damage. Before adjusting
opener down pressure, set bypass valve per “Setting the
Bypass Valve” on page 20.

4. In some applications, pressure on center section is
set slightly higher than the wings to account for
additional compaction from drill transport tires and
tractor tires. The recommended pressure range for
drilling is between 1200 psi and 1800 psi.

#1 is capable of taking nearly 100 percent of available
hydraulic flow. Operating the openers or markers on
circuit #1 will starve the other circuit, making one function
inoperable.
To operate markers and constant opener down pressure
at the same time, connect the openers to circuit #2 and
the markers to circuit #3.
Non-Active Hydraulic System
To run drill with open-center hydraulics or
fixed-displacement hydraulic pumps requires a Great
Plains kit, part number 194-143A. After installing the kit,
refer to the following instructions for opener operation.
1. Lower opener frames by pushing forward on tractor
hydraulic lever. Lock lever temporarily in this position
while adjusting opener down pressure.
Refer to Figure 26
2. With tractor hydraulic lever locked forward, release
lock disk and set down-pressure with adjustment
knob . Watch pressure gauge and dial in desired
1

pressure on openers. There is one pressure-control
valve for openers on center section and one for
openers on wing sections of drill.
Note: Rotate knob clockwise to increase pressure and
counterclockwise to decrease pressure.
3. Once pressure is set, set knobs with lock disks .
1
4. After opener down pressure is set, return tractor
hydraulic lever to neutral. This locks-in the selected
pressure, and opener frames remain fixed in this
position.
Machine Damage Risk: Open-center tractors and tractors
with fixed-displacement pumps are not designed to provide a
continuous supply of pressurized oil to remote valves. Locking
hydraulic lever forward on these tractors can cause overheating of hydraulic oil and tractor damage. After setting opener
down pressure, always return hydraulic lever to neutral.
Note: On some tractors with very positive remote hydrau-
lic checks, a slight increase in the reading on the
pressure gauges may occur after tractor remote lever is returned to neutral. This is caused by back
pressure on opener cylinders and should be ignored. The net operating pressure on opener cylinders is maintained at the pressure you selected
while tractor remote lever was held forward-not at
the apparently increased pressure. Reactivating
tractor lever forward will confirm this.

During operation:
• Each time openers are lowered, hold tractor remote
hydraulic lever forward for a few seconds to recharge
circuit, then return it to its neutral position. The tractor
and drill should be on level ground when returning
tractor lever to neutral.
• When approaching rough terrain where you need
active hydraulics to maintain even opener penetration,
push tractor hydraulic lever forward momentarily. As
soon as you return to level ground, return lever to neutral. Do not activate tractor hydraulic lever for more
than 20 seconds at a time, once every 2 minutes.
Always wait until tractor and drill are on level ground
before returning lever to neutral. You can bump tractor
hydraulic lever forward any time on level ground to
assure the preset pressure is correctly locked in and to
reset the system.
• Always raise openers before turning. Never back up or
turn sharply with openers in the ground. Doing so will
plug openers and may damage equipment.
Position Seed Cup Doors
If planting from the main seed box, check/set all the
meter doors before loading seed.
Refer to Figure 27,
which depicts the seed cup door handle in position .
At each main seed box 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.

Loading Seed Boxes
Seed may be loaded in the field or prior to transport.
Fully loaded with dense seed, the drill can weigh an
additional 5933 lbs (2691 kg). Include this weight when
checking tractor capability.
The drill must be hitched for seed loading. The
mainframe may be raised or lowered. Lowered places
the walkboards closer to the ground, reducing effort
when manually loading bagged seed. If equipped with
ladders, swing them down.

• Check that any offset box dividers are set to the
desired compartment ratio. See “Offset Box
Divider” on page 92.
• Check that the divider flap is set as desired (sepa-
rate compartments, or all-seed). See “Fertilizer
Box Operation” on page 36.
• If seeding only from the forward (seed) compart-
ment, flip the top spill flap (page 38) back to prevent seed from entering the fertilizer
compartment. See “Fertilizer Box Operation” on
page 36.
5. Take all necessary materials safety precautions if the
seed is treated.
6. Load seed evenly into seed boxes.
7. To reduce wear, remove main shaft drive chains for
small seed boxes.

Acremeter Operation
The acremeter, located on the drill clutch shaft, counts
shaft rotations whenever the shaft is rotating - this is with
the drill lowered and in motion or during calibration crank
operation. The meter is programmed to display rotations
as acres or hectares
factory-specified tires and tire inflations.
Note: Unusual conditions and/or non-standard row spac-
ings can cause the acremeter tally to vary from actual acres planted.
Normal Operating Sequence
Note: The acremeter counts rotations during drill calibra-
tion (and if so, can be useful for calibration, although the meter must be on, or moved to the shaft
being cranked).
1. Record the acremeter reading at the start of planting
(and after calibration). The large “12345.6” format
display is the grand total area since meter installation. The smaller number in the lower left corner is
the number of revolutions per acre for which the
meter was factory-programmed. If the display is
blank, see “Dormant Display” below.
2. Lower drill and plant. Acremeter counts shaft rotations, calculates acres or hectares, and adds to the
running grand total.

3. During planting (drill lowered and moving forward),
the display blanks (goes dormant), but area tally continues.
4. When raised for turns, obstructions and transport,
the clutch disengages, the shaft stops, and the meter
counts no additional (non-planting) rotations.
5. Whenever shaft rotation stops, the LCD display activates after 30 to 60 seconds, and remains visible for
30 to 45 minutes.
6. At the completion of planting, record the final reading
or the grand total. If the display goes dormant before
you can read it, see “Dormant Display”.
7. Subtract the reading at Step 1 from the reading at
Step 6 for the total planted in the present session.
Dormant Display
Refer to Figure 37
To conserve power, the LCD display blanks itself most of
the time. If you need to read the display after it has
“timed out” and gone dormant:
• use the calibration crank to turn the jackshaft once, or
• gently tap or wave a magnet at either of the Great
Plains logo spots on the lower region of the display.

Marker Operation
Optional markers are equipped with a double-selector
valve, on the tongue near the hitch, to combine the
box-fold circuit with the marker circuit. On a 2-outlet
tractor, there is a second selector valve, for the lift
circuits, mounted above the marker/fold selector.
Refer to Figure 38
After drill is unfolded for field operation, move
double-selector valve handle from forward fold position
1 2
to marker circuit (back ). Before operating markers,
make sure they are properly bled as described in
“Bleeding Hydraulics” on page 69.
2
Single Marker Operations
To operate a single marker, activate tractor remote
hydraulic lever to move marker in desired direction.
Single markers are equipped with a needle valve to
control marker folding speed. Excessive folding speed
can damage markers, so adjust needle valve to a safe
operating speed as described under “Marker Speed”on
page 62.
Dual Marker Operations
Dual markers are equipped with an automatic sequence
valve to control lift sequence. Starting with both markers
up, the sequence is:
• Activate hydraulic lever; right marker lowers while left
marker stays up.
• Reverse hydraulic lever; right marker raises while left
marker stays up.
• Activate hydraulic lever; left marker lowers while right
marker stays up.
• Reverse hydraulic lever; left marker raises while right
marker stays up.
Pattern repeats.
Folding speed of dual markers is adjusted with
adjustment screws on sequence-valve body. Excessive
folding speed can damage markers, so adjust markers to
a safe folding speed as described under “Marker
Adjustments” on page 59.

Lift Selector Valve Operation
Tractors with only two remote circuits need an optional
selector valve, which shares a single tractor circuit
between transport lift and opener lift. Two Outlet Tractor
Hydraulic Kit Great Plains Part number 194-122A. This
combines the transport lift hydraulic circuit and opener lift
hydraulic circuit.
If no markers are installed, the lift selector valve is
mounted on the standard tongue valve plate near the
hitch. If markers are also installed, the lift selector valve
mounts above the marker valve on an extension plate.
Refer to Figure 39, which depicts the optional lift selector
valve on a drill without markers.
To operate, move handle from forward transport lift
position to rear opener lift position .

Point Row Operation
Refer to Figure 39
The optional point-row controller allows you to raise and
lower openers on one drill section independently of the
others. A POINT ROW CONTROL module in the tractor
cab operates solenoid valves on the drill, which raise and
lower opener sub-frames independently (or together).
The mechanical clutches on each section suspend
seeding when raised.
To raise and lower openers on all sections together, set
POWER switch ON-left, so MASTER LIFT CONTROL
indicator is illuminated. Raise or lower with the ALL
UP / ALL DOWN switch under the indicator.
To raise and lower opener sections independently, set
POWER switch ON-right so SECTION CONTROL
indicator is illuminated. Raise and lower openers on
each section by operating the UP / DOWN switches
illuminated under the SECTION CONTROL.
Note: Turn Point Row POWER switch to OFF-center
when tractor is off.

Shaft Monitor Operation
The optional shaft monitor generates an alarm if any one
or more of the three main seed box meter shafts on the
drill stop turning for more than 20 seconds.
Refer to Figure 41
To operate shaft monitor, turn system on by activating
on-off switch on monitor head. If seed-cup shafts are
turning, all three indicator lights are illuminated and no
alarm sounds.
If any seed-cup shaft stops for 20 seconds, an alarm
sounds and the indicator for that section flashes on the
monitor, designating the failed shaft.
Note: The 30-second delay is to prevent nuisance alarms
when turning at the end of the field.
Note: If a failure does occur and an alarm sounds, re-
member you have traveled for 20 seconds without
planting with that drill section. If due to wheel lift or
low tire pressure, you may have been planting at
progressively lower populations before that.
Note: Older (Vansco) monitors alarm dwell time was 30
seconds.

Parking
Following these steps when parking the drill for periods
of less than 36 hours. For longer periods, see “Storage”
on page 46.
Parking with Drill Unfolded
1. Remove jack from storage location on top of tongue
and pin it on post on left side of tongue as shown on
page 16. Extend jack until weight of tongue is on
jack. Leave tractor hitched for the moment.
Refer to Figure 42 and Refer to Figure 42
2. Lower parking stands located on outer ends of drill
by unpinning keeper pin and rotating stands down.
Place a block under foot of stand if it does not contact the ground.
3. Lower openers and reduce hydraulic down pressure
to zero.
4. Unplug drill hydraulic hoses and electrical lines from
tractor.
Use caution when removing the hitch pin. Slight tongue elevation may occur, even with openers and parking stands lowered.
5. Remove hitch pin first, then safety chain from tractor
drawbar.
Note: After unhitching the unfolded drill, the tongue may
rise above tractor-drawbar height. Lower tongue by
connecting the opener-lift circuit and pressurizing
openers.
Crushing Hazard: This drill has a negative tongue weigh
when unfolded and openers are raised. Lower parking stand,
lower openers and remove hydraulic down pressure before
unhitching the drill in the unfolded position. Unhitching in the

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 3S-3000HD has double-disk openers with
depth-control press wheels mounted on floating opener
frames. Opener bodies are staggered for easy soil flow.
All openers pivot on a common axis to maintain
consistent depth as the opener frames follow contours. 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. 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.
Seed and Fertilizer Rate
Materials are applied by fluted feed meters driven by the
gauge wheels. Independent mechanisms control seed
and fertilizer application. Optional Small Seeds rate is
controlled entirely by Rate Handles. Details are found in
the Seed Rate Manual (195-068B).
Adjustment Page The Adjustment Affects
Main Box Seed rate is controlled by adjustments for:
• Drive Type sprocket (one sprocket each gauge wheel)
• Seed Rate Handle (one handle each seed box)
• Feed Cup Door (one each seed tube)
Fertilizer rate is controlled by:
• Range sprockets (one set each fertilizer box)
• Final Driver/Driven sprockets (one set each box)
Planting Depth
Setting nominal planting depth, and achieving it
consistently, is affected by multiple adjustable drill
functions, from greatest to least effect they are:
• Opener Depth (Press Wheel Height)
• Opener Frame Down-Force,
• Row Unit Down Pressure (Spring),
• Opener Height,
• Opener-Subframe Adjustment,
• Frame Weight (at higher pressures), and;
• Disk Blade Adjustments (as blades wear).

Seed Rate Manual, and rely on data from that manual,
normally located in the manual pak enclosure at the rear
of the left wing.

Setting Main Box Seed Rate
Accurately obtaining the desired seed population
requires four steps:
1. Setting Drive Type sprockets (from chart)
2. Setting initial Seed Rate Handle (from chart)
3. Positioning Seed Cup Door (by seed type)
4. Calibration: checking actual seeding rate
Seed rate charts are provided in the separate Seed Rate
Manual (which is normally stored in a weatherproof
holder on the drill, for field reference). The charts list
proper sprocket pairings and seed-rate-handle settings
for various seeds and seeding rates.
Setting Fertilizer Rate
The 3S-3000HDF fertilizer meters are driven from the
clutch shaft through a series of sprockets. This system is
independent of the seed meter drive, and is unaffected
by Drive Type. Fertilizer rate is adjusted in three steps:
1. Setting the Range sprocket per the Seed Rate Manual
2. Setting the Driver/Driven sprockets
3. Calibrating
Small Seeds Rate
Seeding rate from the optional Small Seeds Attachment
is controlled entirely by seed rate handles on each small

Frame Level
Refer to Figure 44
The 00HD Series openers are designed to produce
optimal results when the opener frames are level with the
ground. Operating with drill frame level is also
recommended, and this is set by hitch height (page 16).
If planting depth is not as desired on just one or two drill
sections, first check the setup items for “Leveling the
Drill” on page 74. Then check and adjust the following
items:
• opener sub-frame adjustment: all gauge wheel trunnions in same frame pivot holes - see “Opener-Sub-
frame Adjustment” on page 53,
• opener pivot height: all openers pivoting in same hole
at their mounts (possibly excepting rows in tire tracks)
- see page 55,
• opener press wheel height: all row units set the same see page 58, and;
• opener spring down-force: all row units set the same
(possibly excepting rows in tire tracks) - see page 55.

Frame Weight
The standard 3S-3000HD includes 1697 pounds (770kg)
of weight bars inside the main tool bar. This, plus the
extra weight of 00HD row units, permits adjustment of
the full range row unit down forces. If markers are
installed, additional force is available.
Although suitcase weight brackets are available for
earlier model 3S-3000 (non-HD) drills, these weight kits
are not recommended for 3S-3000HD drills.
Opener Frame Down-Force
Crushing Hazard: You will be seriously injured or killed if you
are caught between raising openers and drill frame. Always
stop tractor engine, set park brake, and remove key before
adjusting or servicing openers. Keep all bystanders well away
during drill operation.
High Pressure Fluid Hazard: 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, see a doctor immediately.

Hydraulic opener down pressure controls drill-wide
opener penetration and press-wheel soil firming. Use
only enough down pressure to cut a furrow and maintain
proper soil-firming over seed. Excessive opener down
force may cause bulldozing of the openers in light soil
conditions, and leads to premature wear on opener
components.
The table at right shows the approximate force at
openers for a given pressure at the pressure control
valve.
Note: To account for additional compaction from drill and
tractor tires, set pressure on center openersslightly
higher than wing openers.
To run the drill with constant opener down pressure
requires an Active Hydraulic System. An Active Hydraulic
System requires a tractor with closed-center hydraulics
or pressure/flow compensated hydraulics powered by a
variable displacement hydraulic pump. (If you are not
familiar with your tractor’s hydraulics, consult your tractor
dealer.)
Machine Damage Risk: Tractors with load-sensing hydraulics
must use the bypass valve to operate the 3S-3000HD. Failure
to use the bypass valve can cause major tractor damage.
Before adjusting opener down pressure, set bypass valve per
“Setting the Bypass Valve” on page 20.
Note: To run the drill on tractors with open-center hydrau-
lics or on tractors with fixed displacement hydraulic
pumps you must install a Great Plains kit, part number 194-143A. Contact your Great Plains dealer for
ordering information. See “Non-Active Hydraulic
System” on page 33.

Setting Hydraulic Down-Pressure
1. Lower openers to the ground. Lock hydraulic lever
forward for constant hydraulic flow.
You must lock hydraulic lever forward. See “Opener Operation” on page 31.
Refer to Figure 48
2. Release lock disk . Turn knob on pressure-con-
1 2
trol valve while watching pressure gauge, turn knob
until gauge shows desired pressure. Turn clockwise
to increase pressure. Turn counterclockwise to
decrease pressure.
There is one pressure-control valve for openers on
the center section and one for openers on the wing
sections of the drill.
Refer to the chart on page 51 for approximate force
at the openers for a given pressure setting. As a general starting point, set hydraulic down pressure to
1200 psi. For most field conditions, adjust down
pressure between 1200 and 1800 psi.
Population Risk:
Do not operate at pressures so high that the gauge wheels
loose traction, or are off the ground, resulting in skips and
poor seed metering.
3. Once pressure is set, lock knob with lock disk. If
using a non-active hydraulic system to run drill,
unlock the hydraulic remote lever and return it to
neutral.

Machine Damage Risk:
Open-center tractors and tractors with fixed-displacement
pumps are not designed to provide a continuous supply of
pressurized oil to remote valves. Locking hydraulic lever forward on these tractors can cause overheating of hydraulic oil
and tractor damage. After setting opener down pressure,
always return hydraulic lever to neutral.

Great Plains Manufacturing, Inc. Table of Contents Index Adjustments 53
Opener-Subframe Adjustment
Refer to Figure 49
Each drill section has an opener frame which pivots
about the centerline of the drill gauge wheels. These
floating opener frames have the ability to rock the
openers 15 degrees up and 15 degrees down as a
group. By pivoting at the gauge wheels, openers
maintain a consistent depth as opener frames rock up
and back.
Down pressure for each opener frame is provided by two
cylinders working on a constant lever arm. When
combined with live hydraulics, the cylinders provide
constant down pressure across the width of each opener
frame – regardless of how the frame is positioned. Two
cylinders per opener frame along with special trunnions
2
also provide some ability for one end of an opener
frame to rock independent of the other while maintaining
constant opener down pressure across the frame.
FigureSpacer
At higher down-pressures (above 1800 psi), the row units
can tend to tip forward. An adjustment to the
mainframe/subframe pivot corrects this.The opener
frame has one adjustment point for two different
2
operating positions.
Refer to Figure 50 (shown at factory setting)
You can adjust opener frames between two operating
positions–one for normal down pressure and one for
higher down pressure. The adjustment is near the
opener frame pivots. There are three holes and two
bolts. The bottom bolt serves as the pivot. The top bolt
3
is for adjustment.
• For normal drilling conditions, keep top bolt in second
(middle) hole at all six frame pivots. Use this setting
4
when drilling with opener down pressure below 1800
psi.
• When drilling with opener down pressure above 1800
psi, place top bolt in top hole on all six pivot points
5
across drill.
To change the bolts (to high pressure):
1. Have a jack at hand.
2. Loosen the nuts on all the top bolts .
4
3. Lower the opener sub-frames.
4. Put the tractor hydraulic circuit for the openers in
float.
5. Place jack under an opener tool bar at an arm.
6. Lift the tool bar until the bolt is free.
7. Remove the bolt.

Row Unit Adjustments
Refer to Figure 51
(which depicts a row unit fully populated with all optional
accessories supported for use with the 3S-3000HD drill)
From front to back, a Great Plains 00HD Series row unit
can include the following capabilities (some optional):
1. Opener height adjustment: standard
If a few rows need to run deeper, such as in tire
tracks, the arm’s pivot point may be lowered. See
“Opener Height” on page 55.
2. Single Down Pressure Spring: standard
Each row unit is mounted on the drill as a pivoting
arm which allows the row unit to independently move
up and down. The adjustable spring provides the
force to get the row unit and attachments into the
soil. See “Row Unit Down Pressure (Spring)” on
page 55.
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 “Disk Blade Adjustments” on page 56.
4. Seed delivery tube: standard
No adjustments are necessary.
5. Disk Scraper: optional
In sticky soils, a scraper helps keep the opener disks
operating freely. See “Disk Scraper Adjustments”
on page 56.
6. Seed firmer: seed flap (not shown) standard:

Opener Height
The depth to which the opener disk blades penetrate the
soil is controlled in front by the tool bar and pivot (opener
height), and in the back by the press wheel height.
If the actual ground level is lower for some rows, such as
those in tire tracks, you can lower that row unit by
lowering the pivot point.
Refer to Figure 52
1. Raise the drill just enough to relieve tension in the
down-pressure spring.

with bolt.
Note: No spring tension or position adjustment is re-
quired if opener height is changed. The pivot holes
are designed for neutral effect on spring tension.
(The bolt at the top end of the spring uses a hole
that depends on spring length, and not opener
height.)
FigureSpacer
Row Unit Down Pressure (Spring)
For planting in tire tracks, and for no-till conditions, you
can increase spring pressure on individual openers, or
all openers. Adjust the spring in conjunction with the
subframe down-force, and opener height, to keep the top
of the row unit parallel to the ground.
Refer to Figure 53 and Figure 54
To increase spring pressure:
1. Loosen jam nut at lower end of opener spring.
2. Tighten flange against spring tension.

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 55
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 to 1.75in
(0-4.4cm).
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.

The seed flap requires no adjustment, but may need to
be replaced if worn, and may need to be shortened if an
optional seed firmer is added after initial delivery.
Sharp Objects Hazard:
Row unit disk blades may be sharp. Use caution when making
adjustments in this area. To adjust the Keeton Seed Firmer,
lower the drill until the disks of the row units are resting on the
ground.
Keeton Seed Firmer Adjustment
The optional Keeton Seed Firmer is an engineered
polymer shape that slides down the seed trench. It traps
seeds as they exit the seed tube and firms them into the
bottom of the “V”.
1
Refer to Figure 58
The Firmer is provided with a preset tension which is
recommended for using the first year. The tension screw
1
can be tightened in subsequent years according to
your needs. Firmers should provide just enough tension
to push seeds to the bottom of the trench.
Seed-Lok™ Seed Firmer Lock-Up
Optional Seed-Lok firming wheels provide additional
seed-to-soil contact. The wheels are spring loaded and
do not require adjusting. In some wet and sticky
conditions the wheels may accumulate soil. To avoid
problems associated with this, you can lock-up the
firmers.

Marker Adjustments
Pinch, Crush and Sharp Object Hazards:
You may be injured if hit by a folding or unfolding marker.
Markers may fall quickly and unexpectedly if the hydraulics
fail. Never allow anyone near the drill when folding or unfolding the markers.
There are four operating adjustments for markers:
• Marker Width
Once set for a specific row spacing, this only needs
periodic checking to ensure the clamp is secure.
• Disk Angle
Even if your row spacing rarely changes, you may
need to adjust disk angle for soil conditions and planting speed.
• Chain Length
You may want to adjust the chain length to ensure the
markers track uneven ground, and do not drag excessively when markers are folded.
• Marker Speed
Once initially set by your dealer, this rarely needs
modification.
There are also three maintenance items for markers:
•“Bleeding Marker Hydraulics” on page 73
•“Marker Shear Bolt” on page 80
•“Marker Disk” on page 81
Marker Width
Marker extension depends on drill size, row unit spacing
and row units in use.
See “Marker Setup” on page 106 for initial values for
marker extension.
Refer to Figure 61
To adjust marker width, loosen two jam nuts and then
their bolts and slide arm tube in or out. Re-tighten
bolts, then the jam nuts.

Marker Chain Adjustment
There are two basic adjustments needed on the marker
chain, especially in new installation. These adjustments
are interrelated and should be done in the following
order:
Refer to Figure 62
Marker Lifting Slack
1. Start with the marker in the unfolded position.
2. Loosen jam nuts . Back the full threaded adjustment bolt toward nuts until the head extends as lit-
2
1
tle as possible.
3. Slowly fold the marker, observing the motion of the
disk.
If the marker disk slides across the ground more
than about a foot (30cm) before the chain and linkage lifts it up, the chain is too long. Shorten the chain
by moving the clevis one or two links inboard from
3
the end of the chain. Check the adjustment by
repeating the folding process.
If the chain is too short when the marker is unfolded,
it will prevent the end of the marker from dropping
down to follow a depression in the field. Correct this
condition by moving the utility clevis one or two
3
links toward the end of the chain to make it longer.
Marker Folding Slack
1. After the adjustments in step one have been completed, fold the marker.

Marker Speed
The procedure for adjusting marker speed is different for
single marker with needle valve and dual markers with
sequence valve.
Single Marker/Needle Valve Speed
Refer to Figure 65
A needle valve controls the folding speed. The needle
valve is near the rod end of the marker cylinder.
With tractor idling at a normal operating speed, adjust
marker folding to a safe speed. Turn adjustment knob
clockwise to reduce folding speed or counterclockwise to
increase folding speed. Excessive folding speed could
damage markers and void the warranty.
FigureSpacer
Dual-Marker/Sequence Valve Speed
There is one adjustment screw for unfolding speed
and one for folding speed . You can identify adjustment
2
1
screws by markings stamped in valve body.
Turn adjustment screws clockwise ( : slower) to
S
decrease [un]folding speed and counterclockwise
F
( : faster) to increase [un]folding speed.
With tractor idling at a normal operating speed, adjust
marker folding to a safe speed. Excessive [un]folding
speed could damage markers and void the warranty.
After adjusting the folding speed, tighten jam nuts on hex
adjustment screws to hold settings.

If opener disks turn freely by hand but not in field, lessen down pressure on
opener hydraulics.
Check press wheel adjustment for seeding depth.
Check tire pressure. See “Tire Inflation Chart” on page 98.
Check wing gauge wheel size. Proper size is 265/70B 16.5 NHS skid steer.
Seed treatment will affect seeding rate if the chemicals build up in seed cup.
Unless cleaned regularly, this build-up can cause breakage of the feed shaft.
Check drill box setting.
Heavier or lighter than average seed weight being planted. See Operator’s Manual for instructions on calculating seed rate.
Position feed cup handles to a lower notch.

Problem Solution
Grain box not emptying evenly Certain models do not have the same number of seed cups between each divider
of bulkhead. The section with the larger number of cups will empty sooner.
If drill has multiple boxes, check drive sprocket arrangement on each box to see
that they are set the same.
Press wheel or openers plugging
Feed cup sprockets locked
up or twisted feed drive shaft
Openers drill too deep
(Bulldozing)
Front of openers dropping too
low in hard or minimum till
conditions
Openers raise when tractor
remote hydraulic lever is held
forward and lower when lever
is held rearward
Opener frames do not float
over uneven terrain
Pressure gauges read zero
when openers are lowered and
tractor remote hydraulic lever
is held forward.
Pressure gauges show pressure when the openers are
raised.
Transport lock channels will
not stay in position for transport.
Hydraulic marker functioning
improperly
(Optional equipment)
Drilling in damp or wet conditions may increase this problem.
Reduce hydraulic down pressure on openers.
Does not back up drill in field, or stop and allow drill to roll backwards with openers in the ground.
Check Seed-Lok Wheel.
Check for foreign matter lodged in one or more feeder cup sprockets.
Liquid insecticide from seed has dried within feed cups. Remove build up by disassembling each feed cup and scrape foreign substance from the turning surfaces. NOTE: Liquid insecticide should be applied with caution and care should
be taken to clean the feed system after drilling treated seeds.
Reduce hydraulic down pressure on openers
Check press wheel adjustment
Set opener frame cross bolt in top hole. See “Opener Height” on page 55.
Opener hydraulic down pressure set too high
Reverse the hydraulic hoses at the tractor quick couplers.
Tractor remote hydraulic lever not being held in the forward position on the circuit
designed for hydraulic motor control. See “Active Hydraulic Systems” on
page 32.
The hoses are routed incorrectly between the pressure control valve and the
opener lift cylinders. See “Opener Lift: Standard Closed-Center” on page 102
or “Opener Lift: Optional Open-Center” on page 103.
The hoses are routed incorrectly between pressure control valve and opener lift
cylinders. See “Opener Lift: Standard Closed-Center” on page 102 or “Opener
Lift: Optional Open-Center” on page 103.
Check u-shaped clip in lock channel. Clip must clasp cylinder rod securely. If necessary, tighten or loosen clip by turning the bolt on the clip.
Before transporting, check that the hydraulic cylinders have settled against the
lock channels. The weight of the cylinders help hold the lock channels in place.
Check all hose fittings and connections for air and oil leaks.
Check tractor hydraulic oil level.
Check all bolts and fasteners.
If needle valve is plugged; open valve, cycle markers, and reset the needle valve.

Problem Solution
Marker disk does not mark
(Optional equipment)
Chain-debris/retainer clip
End of Troubleshooting
The maximum marker down float is limited by the slots at the rod end of the
marker cylinder. If the blade does not drop down to follow depressions in the field,
make sure the marker cylinder is fully extended.
The blade may be reversed to pull dirt in or throw dirt out depending on soil conditions.
If a smooth blade does not provide an adequate mark an optional notched (no-till)
blade assembly is available through your Great Plains dealer. Under some conditions, the more aggressive notched blade will leave a more visible mark.
Be sure retainer clip open end is facing the opposite way of chain travel.

Maintenance and Lubrication
Proper servicing and maintenance is the key to long
implement life. With careful and systematic inspection,
you can avoid costly maintenance, downtime and repair.
Always turn off and remove the tractor key before making
any adjustments or performing any maintenance.
OFF
Crushing Hazard:
You may be severely injured or killed by being crushed under a
falling implement. Always have frame sufficiently blocked up
when working on, and particularly under implement.
High Pressure Fluid Hazard:
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can
be almost invisible. Use paper or cardboard, not body parts,
and wear heavy gloves to check for suspected leaks. If injured,
seek immediate medical assistance from a doctor that is familiar with this type of injury.
After using drill for several hours, check all bolts to be
sure they are tight.
1. Securely block drill before working on it.
2. Lubricate areas listed under “Lubrication” on page
83.
3. Clean any fittings that do not take grease.
4. Inflate tires as specified on “Tire Inflation Chart”on
page 98.
5. Inspect hydraulic hoses for cuts, cracks and aging.
Check fittings for evidence of leaks.
6. Keep disk scrapers properly adjusted.
7. Replace any worn, damaged or illegible safety
decals. Order new decals from your Great Plains
dealer. See “Safety Decals” on page 6.

Materials Clean-Out
Main Seed Box Clean-Out
Refer to Figure 67, which depicts the seed cup door handle
in a normal operating position.
1. Set the Seed Rate Handle to zero (0) for the section
of the drill to be cleaned out. This moves the seed
cup sprockets out of the seed path.
2. Position a tarp or bucket under each row or set of
rows to be cleaned out.
3. At the seed cup for that row, pull the door handle
1
out of the operating detent range, and swing it down
to position .
2
4. Open the main seed box and use a small brush to
sweep seed toward seed cups set to clean-out. If
seed does not flow freely, inspect seed cup, hose
and seed tubes for obstructions.
5. Wash out the seed box with high pressure water.
It is not necessary to operate the seed meter drive shaft
for clean-out. With the Seed Rate set to zero, nothing
moves inside the seed cups; however, an inspection of
the flutes for excess wear and damage does require
shaft rotation.
Set the Seed Rate Handles to 100. With openers raised,
the seed meter jackshaft can be slowly turned by one
person with a
7
⁄
in (22mm) open-end wrench, while
8
another inspects the flutes from the open seed boxes.
Fertilizer Box Clean-Out
After applying fertilizer, clean drill boxes as soon as
possible. Fertilizers often contain chemicals corrosive to
metal.

1. Open lid of each box and scoop out as much seed as
possible.
2. To recover remaining seed, place a collection tarp
under the small seeds tubes at the openers.
3. Raise drill.
4. Set Small Seeds rate handles to 100.
5. Rotate gauge wheels until no seed flows.
6. If a vacuum cleaner is available, remove any residual
seed from top of meters.
Chain Maintenance
Inspect and lubricate chains regularly. The slack of new
chains tends to increase during the first few hours of
operation due to seating.
Chain Slack
Check slack within the first 8 hours of operation and
tighten idlers as necessary.

Refer to Figure 70, which, for clarity, greatly exaggerates
slack, and omits the idlers.
1. Measure the span for allowable slack:
1
Locate the longest span of each chain (usually the
span which does not run through the idlers).
2. Determine the ideal slack:
Long chains (over 36in/91cm):
Vertical short chains:
Horizontal short chains:

4
in per foot (2.1cm/m)
⁄
in per foot (4.2cm/m).
2
2
Acting at a right angle to the chain span at the center
of the span, deflect the chain in both directions. The
slack is the distance of the movement.
4. Adjust the idlers for ideal slack.
Whenever mounting a chain, make sure the clip at the
removable link is oriented to minimize snags.
Refer to Figure 71
Note: Install clip with open end facing away from direction
of chain travel (shown by gray or striped arrows in

Bleeding Hydraulics
To function properly, the hydraulics must be free of air. If
hydraulics have not been bled, they will operate with
jerky, uneven motions and could cause wings to drop
rapidly during folding or unfolding. If hydraulics were not
bled during initial implement setup or if you replace a
part in hydraulic system during the life of the drill,
complete the following procedures.
High Pressure Fluid Hazard:
Escaping fluid under pressure can penetrate the skin causing
serious injury. Avoid the hazard. Relieve 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.
Crushing Hazard:
Raising openers on unfolded, unhitched drill will cause drill
tongue to rise suddenly, which could cause serious injury or
death. Be certain that drill is hitched securely to your tractor
drawbar and the safety chain is securely attached to tractor
before raising openers and unfolding drill.
Bleed only at:
JIC (Joint Industry Conference, 37° flare) or
NPT (National Pipe Thread, tapered thread) fittings.
Never bleed at:
ORB (O-Ring Boss) or
QD (Quick Disconnect coupler) fittings.
Check hydraulic fluid level in tractor reservoir and fill to
proper level. Add fluid to system as needed.
Note: System capacity for entire drill is about
1
4
⁄
U.S. gallons
2
(17 liters).Bleeding Fold Hydraulics
Over-Torque Leak Risk:
JIC fittings do not require high torque. Excess torque causes
leaks. JIC and O-ring fittings do not require sealant.
System Contamination Risk:
Always use liquid pipe sealant when adding or replacing
(NPT) pipe-thread fittings. To avoid cracking hydraulic fittings from over tightening, and to keep tape fragments from
clogging filters, do not use plastic sealant tape.

Leveling the Drill
To perform leveling, the drill must be hitched to a tractor,
with at least the hydraulics connected.
Negative Tongue Weight:
Raising openers on unfolded, unhitched drill will cause drill
tongue to rise suddenly, which could cause serious injury or
death. Be certain that drill is hitched securely to your tractor
drawbar and the safety chain is securely attached to tractor
before raising openers and unfolding drill.
Center Box Frame Leveling
1. Park the drill on a clean level surface.
