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.
7/12/2005
! DANGER
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.
! WARNING
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.

Important Safety Information 3
Transport Machinery Safely
Maximum transport speed for implement is 20
mph. Some rough terrains require a slower
speed. Sudden braking can cause a towed load to
swerve and upset.
▲ Do not exceed 20 mph. Never travel at a
speed which does not allow adequate control
of steering and stopping. Reduce speed if
towed load is not equipped with brakes.
▲ Comply with state and local laws.
▲ Do not tow an implement that, when fully
loaded, weighs more than 1.5 times the weight
of towing vehicle.
▲ Carry reflectors or flags to mark planter in
case of breakdown on the road.
▲ Keep clear of overhead power lines and other
obstructions when transporting.
▲ Do not fold or unfold the planter while the trac-
tor is moving.
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, see a doctor immedi-
ately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene may result.
Prepare for Emergencies
▲ Be prepared if a fire starts.
▲ Keep a first aid kit and fire extinguisher handy.
▲ Keep emergency numbers for doctor, ambu-
lance, hospital and fire department near
phone.

▲ Disconnect battery ground cable (-) before
servicing or adjusting electrical systems or
before welding on planter.
▲ 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
planter before operation.
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
911
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.
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
weight involved.

Hitching Tractor to Planter
!
DANGER
You may be severely injured or killed by being crushed
between the tractor and planter. Do not stand or place
any part of your body between planter and moving
tractor. Stop tractor engine and set park brake before
attaching cables and hoses.
Refer to Figure 2
1. Connect your tractor 3-point to the planter 3point hitch. If using quick hitch be sure planter
locks into hitch securely.
NOTE: Be sure tractor has enough hitch capacity
and front end ballast for safe operations. Planter
can exert 9000 lbs. of weight in transport.
2. Raise tractor 3-point just enough to relieve
pressure off of the parking stand.
Important: Adjust 3-point hitch arms and sway
blocks to minimize any side-to-side sway to assure proper tracking in the field and safe road
travel.
! WARNING
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, see a
doctor immediately. Any fluid injected into the skin
must be surgically removed within a few hours or gangrene will result.

Bleeding Hydraulics
Bleeding Lift Hydraulics
Normally the lift hydraulics are bled at the factory
before shipping and bleeding should not be required other than to raise fully and hold lever on
for one minute or until all cylinders extend fully.
Bleeding Fold Cylinder Hydraulics
Normally the fold hydraulics are bled at the factory
before shipping and bleeding should not be required other than to fold fully and hold lever on for
one minute or until all cylinders reach the end of
their stroke.
Important: Do not fold or unfold without first
raising planter completely.
7/12/2005
401-182M

Bleeding Marker Hydraulics
To fold properly, the marker hydraulics must be
free of air. If the markers fold in jerky, uneven motions, follow these steps.
!
CAUTION
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 planter when folding or unfolding the markers.
Check that tractor hydraulic reservoir is full.
1. Make sure and set the solenoid to marker operation.
2. With both markers lowered into field position,
loosen hydraulic-hose fittings at rod and base
ends of marker cylinders. If applicable, loosen
fittings on back side of sequence valve.
IMPORTANT: Never bleed an O-ring fitting. Instead, bleed a nearby pipe or JIC fitting.
3. With tractor idling, activate tractor hydraulic
valve until oil seeps out around a loosened fitting. Tighten that fitting.
IMPORTANT: JIC fittings do not require high
torque. JIC and O-ring fittings do not require
sealant. Always use liquid pipe sealant when
adding or replacing pipe-thread fittings. To
avoid cracking hydraulic fittings from over
tightening, do not use plastic sealant tape.
4. Reactivate tractor hydraulic valve until oil
seeps out around another loosened fitting.
Tighten that fitting. Repeat process until all
loosened fittings have been bled and tightened.

Preparation and Setup 17
Leveling Frame Side-to-Side
All frame sections must be level to maintain even
seeding depth. Before using the planter in the field,
follow these steps to make sure the planter is level
side-to-side.
Periodic frame-leveling adjustments should not be
necessary, but if you are having problems with uneven depth, check planter levelness and follow these
procedures.
Before making any adjustments be sure the lift cylinders are rephased and operating properly.
Complete the steps under “Bleeding Hydraulics,”
page 15, before proceeding.
Refer to Figure 4
21926
1. Lower the planter fully to field position.
2. Set the 3-point for 40”. When setting hitch at 40”,
lower lift cylinders completely, then adjust.
Figure 4
Base Height
Important: Planter must be fully lowered to field
position and hitch height must be set before making side-to-side adjustments.
Refer to Figure 5
3. Locate the threaded eye bolt at the base end of
the gauge-wheel cylinders. The eye bolt is locked
in place by a jam nut. Observe the amount of
thread exposed between the eye and lower nut.
This should measure 1” to 1 1/4”, if so, no initial
adjustment is needed. Go to step 4.
4. If the exposed threads between the eye and lower nut does not measure 1 1/4”, loosen and adjust the jam nuts until it does. Repeat for other
end of planter.
5. Move the planter to a level area. With the planter
unfolded, raise the planter to its highest position
with the lift cylinders. With the tractor idling,
rephase the cylinders by holding the hydraulic lever on for an additional 30 seconds. Immediately
lower the planter until the row-units are just ready
to touch the ground.

6. Move the gauge-wheel eye bolts until the rowunits on the outside end of the planter are the
same height as the center row-units.
NOTE: Eye-bolt adjustments are easier if the planter
is first lowered to the ground to remove some of the
force on the cylinders.
7. Repeat the steps above until the planter is level
side-to-side when planting in actual seeding conditions.

Fan Operation
The fan must be operated with the return oil line connected to a low back pressure sump return on the
tractor. Check with tractor manufacturer for proper
connection of oil sump return line. A low back pressure quick disconnect is supplied with the planter for
ease of connection to the tractor sump return line.
Use tractor remote hydraulic valve flow control to set
fan speed.
Run fan at 4000 rpm in operation.
When starting empty you must blow seed out to the
meters for one to two minutes to fill meters.
Watch monitor and adjust fan speed by increasing or
decreasing hydraulic flow from tractor.
The monitor has a level sensor below hopper to warn
when box is empty. This gives three to four acres of
run time before rows start going empty.
Electric Clutch Operation
Refer to Figure 18
Electric clutches allow you to turn seeding off while
the planter is lowered. A clutch for each drive shaft allows you to control each side of the planter
independently. The clutches are controlled through
the in-cab control console.
19694
Figure 18
Monitor
For regular field operation, turn the electric-clutch
switches on the control console to the on position.
This will activate the magnet on each clutch and allow
the clutch shafts to rotate.
To shut off seeding in one or both sides to accommodate point-row while the planter is lowered, turn one
or both switches to the off position.
Y-Tubes
Refer to Figure 19
Y-tube gates can be shut off to feed only one row for
planting 30” corn on 15” machines. Corn rows are the
rear set rows.
You can also shut off the Y-tube gates to clean out the
air system and meters. Refer to “Cleaning Out Air
System,” page 60.
21999
Check air lines to be sure they do not have any sags
or kinks in them. The air box has internal gates that
may have to be adjusted if air system plugs repeatedly at box outlets. This adjustment is a last resort item,
check fan speed and hose routing first.

Row-Unit Operation
IMPORTANT: Do not back up with row-units in
the ground. To do so will cause severe damage and row-unit plugging.
For information on row-unit adjustments, refer to
“Row-Unit Adjustments,” page 33. For more information on troubleshooting row-unit problems, see
“Troubleshooting”, page 54.
Marker Operation
Optional markers are available through your
Great Plains dealer.
Before operating markers, make sure they are
properly bled as described in “Bleeding the Hydraulics”, page 15.
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 Adjustments”, page 46.
Dual markers are equipped with a sequence valve
to control lift sequence. Starting with both markers up, the sequence is:
1. Activate 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.
Excessive folding speed can damage markers, so
adjust markers to a safe folding speed as described under “Marker Adjustments”, page 46.
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

Transporting
!
WARNING
Towing the planter 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.
Before transporting the planter, follow and check
these items:
!
WARNING
The planter places large loads on the tractor 3-point
hitch in transportation position. Check your tractor
manual and dealership regarding appropriate tire
pressure and front end ballast to carry this load. Too
little front end ballast may cause loss of control.
Set tractor 3-point hitch control for depth control. If the tractor 3-point hitch is set for load
control, the auto load control response may automatically adjust too high in given circumstances.
This will result with the wing locks disengaging on
the road.
Remove seed box. Remove seed box before
transporting if at all possible.
The planter can be transported with a full box of
grain, but the added weight will increase stopping
distance and decrease maneuverability.
Transport planter only while in folded position. Refer to “Folding the Planter,” page 21.
Warning lights. Always use warning lights when
transporting the planter.
Road rules. Comply with all federal, state and local safety laws when traveling on public roads.

each row-unit. The coulters cut through heavy
trash and till a small strip so the row-units can
penetrate the soil easily. To maintain even seeding depth, the coulters must cut even with or 1/4”
below the row-units.
Two coulter options are available, row unit mounted or frame mounted.
Adjust coulters one-by-one when installing them
to get coulter depth even with the bottom of the
row-unit blades. Refer to “Coulter Adjustments,”
page 32, for information on how to make these
adjustments.
Row-Units
Each row-unit is mounted on the planters with
parallel arms. This parallel-action mounting allows the row-unit to move up and down while
staying horizontal. Row-unit double disks widen
the coulter groove, making a seed bed. A seed
tube mounted between the disks delivers seed to
the trench.The down force needed to cut and widen the coulter groove is supplied by four springs
nested in the parallel linkage. Adjusting these
springs changes row-unit down-force. Refer to
“Row-Unit Down Pressure,” page 33, for information on how to make this adjustment.
Press Wheels
Attached to the rear of each row-unit is one of
several press-wheel options.
The press wheels close the furrow, gently pressing the soil over the seed to ensure good seed to
soil contact for even emergence. To provide consistent seed firming, the press wheels are free to
move downward from their normal operating position. This system maintains pressing action
even if the row-unit arm is lifted when the disks
encounter obstructions. For press wheel adjustments refer to “Adjustments,” page 35.

Coulter Adjustments
The planter is assembled so that the coulters are
set even with to 1/4” above seeding depth. This is
a good baseline setting for most seeding operations. As field conditions warrant, you can change
settings on the entire planter or individual
coulters.
Coulter Springs (Frame Mounted Coulters)
The coulter spring length is preset at 10 inches,
giving the coulter an initial operating force of 400
pounds. This setting is adequate for many difficult
no-till conditions. For lighter no-till conditions
where rocks or other obstructions are a problem,
you can lengthen the springs to protect the
coulters from impact. In heavier conditions, shortening the spring will increase coulter force. Refer
to the chart below for adjusting the coulter
springs.

NOTE: Any attempt to reset the coulter spring
length shorter than 9 3/4 inches may contribute to

voided.
Individual Coulters (Frame Mounted Coulters)
Refer to Figure 22
When coulters follow in tire tracks and do not give
satisfactory depth, individual coulters can be lowered by loosening the mounting clamps and
adjusting the coulter to the desired setting.
To retighten clamps, snug the hex-head clamp
bolts (1) just until the u-bolts are tight on each side
of the spring bar. Tighten nuts on u-bolts (2), then
finish tightening the hex-head clamp bolts.
NOTE: There may be as much as a 1/8-inch gap
between the clamp plates even when the coulter
is mounted securely.

Unit Mounted Coulters
Adjust the coulter to run even with or 1/4” shallower than the row-unit disks. In heavy residue or
hard soils, the coulters may need to run deeper.
Refer to Figure 23
1. To adjust the coulter vertically, loosen the 3/4"
jam nut (1) and the 3/4" x 3" long hex bolt (2).
2. By turning the cam hex (3), rotate the cam
casting to set the desired height.
3. Tighten the bolt and jam nut. Refer to “Torque

25 Series Row Units
IMPORTANT: Do not back up with row-units in
the ground. To do so will cause severe damage and row-unit plugging.

Row-unit spring
Row-Unit Down Pressure
Refer to Figure 24
Row-unit springs provide the down pressure necessary for row-unit disks to open a seed trench.
The springs allow the row-units to float down into
depressions and up over obstructions. Springs
also provide down force on coulters when using
optional row mounted coulters.
You can adjust down pressure individually for
each row-unit. This is useful for penetrating hard
soil and planting in tire tracks. For best results always adjust tractor tires so they are not ahead of
30” rows.
Use only enough down pressure to cut the seed
trench and maintain proper soil-firming over seed.
Excessive row-unit down force will lead to premature wear on row-unit components. Excessive
down force will also cause uneven seed depth.

Checking Singulated Seeding Rate
The seed charts are based on cleaned and sized
seed. Extreme seed size variations, foreign material and tire pressure will affect the seeding rate.
Check the seed population rate as described
below.
1. Adjust the planting depth to a shallow setting.
2. Plant at the desired planting speed for a short
distance.
3. Using the table on the right, determine how
many rows need to be counted.
4. Measure a distance of 17’ 5” in the planted area. If 20-inch row spacing is being used, measure a distance of 26’ 2” in the planted area.

5. Count the number of seeds, in the appropriate number of rows, over the distance measured.
6. Multiply the number of seeds counted by
1,000. This is the plant population in seeds
per acre.
Example 1:
If you have twin tows on 30” spacing count both of
the twin rows. If you have a 15-inch row spacing,
plant according to Table 1, two rows must be
counted. Measure 17’ 5” and count the number of
seeds in two rows. If the number is, for example,
180, multiply 180 by 1,000.
180 x 1,000 = 180,000 seeds per acre.
7. If the planting population is significantly different than desired, make the following checks:
• Double check the transmission and range
sprocket combinations. Refer to the seed
population chart for the seed being planted.
• Check the air pressure in the gauge wheel
tire. Refer to “Tire Inflation Chart” on page 97.
• Refer to Troubleshooting on page 54.
Seed rate charts
Seed rate charts begin on page 100. The charts
give transmission sprocket combination and drive
range sprockets for row spacing used, to achieve
the population or pounds per acre desired. The
charts also give seed spacing for singulated seed
and maximum planting speed for both singulated
and volumetric seeds.
Each seed chart has a corresponding page showing the different drive ranges for that seed and a

Adjusting Finger Pick Up Meter
21913
The finger pick up meter has an adjustable brush. It has
been pre-set to the optimum setting for most seed sizes.
Listed below are some basic guidelines for operating
and adjusting the meter.
Figure 53
General Planting Tips
1. Optimum planting speed is 4 1/2 to 5 miles per hour.
Excess speed results in poor spacing performance
due to seed tube bounce. Excess speed may also
result in improper depth control due to row unit
bounce.
2. Always pay attention to your planter monitor. Compare actual seed usage to your estimates.
3. Fine-tune your planter by thoroughly checking all
key components including: Keeton™ Seed Firmers,
seed tubes, chains, sprockets, tire pressure, seed
monitor, double disk openers, gauge wheels, closing wheels, parallel arms and the row unit itself.
Brush
The adjustable brush provides additional flexibility to
accommodate a wide range of seed sizes. Use a flathead screwdriver to gently rotate the brush into position. Use the general guidelines in the table on the right
to adjust the brush position to your seed size and
shape. The numbers listed correspond to the numbers
printed on the outer housing of your meter.
Population Max Inserts
The Population Max backing plate is equipped with an
“a” insert (or an “R” insert). In tests, this insert provides
the best performance in most seed sizes. However,
there are two alternative inserts that can be used. Before changing to a different insert, please consult with a
Great Plains service representative for a
recommendation.
Important: Be cautious in using seed treatments, additives and other chemicals when possible. They
can cause meter performance problems and premature wear to meter parts.
Avoid the use of graphite with the Precision™ Meter.

If graphite must be used, use Precision Planting
graphite or Great Plains graphite which is less abrasive. Generally, seeds coated with Maxi or similar
coatings do not need graphite. Other seed coatings
such as Captan generally benefit from graphite.
Always store meters in a dry, secure place. Moisture,
temperature and mice can create unintended problems.
Always pay attention to your seed monitor, operating
manual and monitor the amount of seed you are
planting compared to your expectations. Always investigate abnormalities!

Strainer
A Banjo brand strainer is supplied with the fertilizer pump
option and is to be plumbed before the Hypro pump. The
standard 80 mesh screen should be suitable for most applications. Other screen sizes are available from Banjo
Corporation. If changing screen sizes, keep in mind the
following.
• A smaller mesh (100) will keep the very small manifold
orifice plates from plugging so often. However, the
screen will have to be cleaned more often.
• A larger mesh (50) or (30) will pass more material but
should only be considered when using large manifold
orifice plates.
• A plugged or partially plugged screen will starve the
pump and will result in a reduced application rate.
Valve
• Mesh sizes: (Smallest) 100, 80, 50, 30 (Largest)
Setting Relief Valve
A relief valve is mounted directly above the pump to protect
the manifold and pump from excessive pressure. Any product that dumps over the relief valve will discharge from the
dump line (1).
Knob
Jam nut
To set relief valve:
Refer to Figure 60
1. Unlock plastic jam nut from relief-valve knob.
22502
Figure 60
Pressure Relief Valve
2. Unscrew knob clockwise until it loses contact with internal spring.
3. Screw knob counterclockwise two turns. Start at this
setting.
4. Observe manifold gauge and watch for relief-valve discharge while operating in the field.
• If valve is dumping product and gauge reads under 85
psi, stop tractor and turn knob clockwise 1/4 turn. Continue operating at normal field speed. Repeat this step
as needed until no product is discharged from relief
valve.
• If the pressure gauge reads above 85 psi, change to a
larger orifice. Go to step 2 and repeat steps.
Orifice Plates
Refer to Figure 61
In general, the orifice (1) needs to be small enough to create at least 5 psi of pressure in the manifold but large
enough to prevent the manifold pressure from exceeding
85 psi. The minimum pressure is required to even out the
flow of fertilizer between rows. To reduce orifice plugging
and pump wear, use the largest orifice practical for your fertilizer application rate. The best pressure range to maintain
is 15-40 psi to ensure optimum distribution while minimizing leakage.

Maintenance and Lubrication
Maintenance
OFF
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.
!
WARNING
You may be severely injured or killed by being crushed
under the falling implement. Always have transport
locks in place and frame sufficiently blocked up when
working on implement.
!
WARNING
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
medical assistance from a doctor that is familiar with
this type of injury. Foreign fluids in the tissue must be
surgically removed within a few hours or gangrene
will result.
1. After using your planter for several hours,
check all bolts to be sure they are tight.
2. Remove excess slack from chains. Clean and
use chain lube on all roller chains as needed.
3. Maintain proper air pressure in planter tires.
4. Keep disk scrapers properly adjusted.
5. Clean planter on a regular basis. Regular and
thorough cleaning will lengthen equipment life
and reduce maintenance and repair.
6. Lubricate areas listed under “Lubrication”,
page 64.
7. Replace any worn, damaged or illegible safety labels by obtaining new labels from your
Great Plains dealer.

Finger Set Installation Instructions
Installation Steps
Great Plains recommends having the meter service performed by a recognized professional repair facility, such
as a certified Meter Max representative.
If you choose to service them yourself follow these procedures when installing the finger-sets.
6. Rotate the finger set clockwise and make sure the fingers open and close properly. Fingers should be
closed at the 8:00 to 2:00 position (exit hole) and
open at the 2:00 to 8:00 position.
Annual Maintenance
Finger sets should be inspected on an annual basis. After
cleaning, carefully inspect the fingers and springs for
wear or other abnormalities that may develop. Excessive
wear may disrupt singulation performance.
Refer to Figure 68
1. Be sure the belt is oriented properly as shown.
2. Slide the finger set over the shaft and rotate clockwise until it properly seats against the backing plate
(you will hear a click).
3. Firmly press the finger set against the backing plate
while tightening the nut.
4. Tighten the nut until contact is made between the nut
and the finger set. Turn 1/4 to 1/2 (1/24 to 1/12 of a
turn) flat (a flat is one of the six sides of the nut) after
contact is made. This equals about four inch pounds
of torque on the nut.
5. Place the slotted nut cover on and carefully align the
slotted nut cover with the shaft hole and insert the
cotter pin.
7/12/2005
Precautions
1. Make sure the finger set is properly torqued against
the backing plate. Improperly torqued finger sets may
disrupt seed singulation.
2. Avoid seed treatments, additives and other chemicals
when possible. They can cause meter performance
problems, premature wear to meter parts and may
cause un-desired chemical reaction or deterioration
to the finger sets. Always use Precision Planting or
Great Plains graphite when using seed treatments,
refer to “Graphite Powder,” on page 68. Graphite from
other sources may cause premature wear.
3. Always pay attention to your seed monitor, operating
manual and monitor the amount of seed you are
planting compared to your expectations. Always investigate Abnormalities.

and replace if necessary.
2. Check for the correct number of machine washers (1)
and flat washer (8) between the side gauge wheel (2)
and the wheel arm (3). There must be five machine
washers (1) and one flat washer (8) between the wheel
bearing and arm with the machine washer (8) next to
the arm. There should be one machine washer (1) and
one lock washer (9) on the outside of the wheel. When
installed, the wheel should turn freely and not hit the
arm at the curve. Do not add any more washers than
necessary.
3. Disassemble side gauge wheel arm (3) from unit. Remove bushing (4) from sleeve (5) and check bushing for
wear. Replace bushing if necessary.
4. When reinstalling side gauge wheels, align tab on hex

Operations
Before going to the field:
1. Once calibration procedure above has been
followed, Console will store the calibration
and rate information until new information has
been entered.
Refer to Figure 99
2. Turn on Console by pressing On/VR key.
Pressing the On/VR key twice will put the unit
in VR (Variable Rate) mode. Leave Console in
manual mode.
NOTE: For units with P/N 21567 skip step 3.
3. To double-check calibration before planting,
follow same procedure as for mechanical
ground drives as outlined in Great Plains Precision Seeding System Operator’s Manual,
with these differences:
22710
Figure 99
• Volumetric: use extreme caution when performing this calibration to prevent injury due
to drive entanglement. Also, turn drive gauge
wheel with a consistent speed of at least 30
rpm for maximum calibration accuracy.
• Singulated: Rather than calibrating from a
standing start, measure the distance as listed
in the GP manual, and set two flags. Start
driving far enough in advance of the first flag
that your unit is operating at field speed (min.
3 mph) during the calibration distance.
In Field:
Refer to Figure 100
1. Turn on Controller Console by pressing the
On/VR key. Green light above On/VR key will
illuminate when power is on. Pressing the
On/VR key twice will put the unit in VR mode.
VR will appear on the screen along with the
Rate that is being sent from the computer.
Press On/VR key again to toggle back to
manual mode. (Mode and rate changes take
effect with the release of the key.)
2. To change rates manually whether in manual
or in VR mode, simply touch the Up/Down arrow keys. This will change the Controller to
the rate you select manually. To return to VR,
simply touch the On/VR key to toggle back to
VR mode.

1. Engage the hydraulic flow by pushing FORWARD on the tractor remote hydraulic lever. The
remote lever must be LOCKED OPEN in this position to provide constant flow to the drive motor.
• John Deere tractors with Sound-Gard ®
body: Use lever lock clip to lock lever forward.
See your tractor dealer for lock purchase and installation.
• John Deere 7000 Series tractors: Rotate valve
detent selector to motor position to lock lever in
forward position.
• John Deere 8000 Series tractors: Set timer to
continuous. Push lever forward until detent
clicks.
• Case-IH Magnum tractors: Lock lever forward
in detent position. You may need to turn up detent pressure to its maximum setting. Do not tie
hydraulic lever past detent position with a strap.
See your tractor dealer for details.
• Other tractors: Lock lever forward in detent position. You may need to turn detent pressure to
maximum or use a mechanical detent holder to
hold lever forward. See your tractor dealer for
proper means of providing constant flow.
2. Press Engage key to activate drive. Green light
above Engage key will illuminate.
NOTE: If you do not move within 10 seconds, the
automatic disengagement feature will disengage
the drive. To begin planting again, you must
press the Engage key.
3. 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 will normally fluctuate within 5% of the “Set” rates. This fluctuation is evidence of
the drive system compensating for minor fluctuations
in ground speed.
4. If “Out” rate varies from the “Set” rate by more
than 20%, an audible alarm will sound.
5. 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.

Plains Precision Population Controller QUICK
REFERENCE GUIDE
(Create a .shp recipe file in FarmWorks Site Pro, SMS
2.0, SSToolbox, or other software that will create a .shp
file, and transfer it to SiteMate.)
SiteMate Settings: (version 8.12)
1. Select CONFIGURE Tab. Select SETTINGS. Select VARIABLE RATE SETUP. Select NEW. Type in
GP PPC. Under CONTROLLER TYPE, select
Rawson from the scroll-down list. Under COMM
PORT select the port number for the serial card or
flash jacket port.
2. Select MAP tab. Enter DEFAULT rate. This will be
the rate that SiteMate will call for if GPS signal is
lost or you are outside the map area. Note: if GPS
signal is interrupted, or if you are outside the map
area, GP Controller will continue applying rate it
was set at when signal was interrupted, until signal
is regained, or another rate is set manually. If power to the SiteMate is interrupted, you will need to
restart the recipe to return to VR. In the CONVERSION window, enter the conversion rate as follows:
if your recipe (.shp file) is written using the entire
number as the desired rate, i.e. 30,000 seeds/acre
on the recipe means 30,000 seeds/acre is the desired rate, enter both the Map Unit and Controller
Unit as 1. If the recipe is written using a different
number, i.e. 30 on the recipe means a population
of 30,000, then you will need to enter the conversion multiple—in that case 1 Map Unit = 1,000
Controller Units.
3. Under the APP tab, enter the Feed Delay as 3 seconds. Enter the Following Distance (the offset from
the Great Plains meters from the GPS) as follows:
for 15’ and 20’ the distance from the opener to the
hitch pin is 18’; for the 30’ model the distance is
26’; Add the distance from the hitch pin to your
GPS location. Enter the total distance in the Following Distance window. Enter the Swath Width of
the Great Plains unit.
4. Under the CTRL tab, enter the Nominal Rate as
follows: Divide the highest rate on your recipe by
1.6. This is your Nominal rate. For example, if your
highest rate is 200,000 the nominal is 125,000. If
your highest rate is 32, your nominal rate is 20. Enter the Step as 4%. Exit VRA Controller Setup by
clicking OK button to save the settings.

Troubleshooting GPS-based Planting with SiteMate
1. No Rx rate appears on SiteMate
• has field been selected? Select VRT file (see
SiteMate Settings, Step 5)
• check recipe to verify that it is valid by viewing Attributes for each zone in SiteMate
• if recipe calls for zero rate as the default, do you
have GPS signal, or are you outside of field?
2. Rx rate appears on SiteMate, but no Applied Rate.
• make sure “Go” button on SiteMate is pressed.
(button should read “Stop” when recipe is being
sent to GP Console)
• you must be planting in order for Applied Rate to
appear.
5. Population Monitor rate does not match GP Controller Console.
• Make certain that SiteMate and GP Controller
Console agree. If not, see Troubleshooting step 4.
• Re-check GP calibration number, with metering
wheel and row spacing.
• Re-check planter monitor settings: calibration
number, row spacing, number of rows, swath
width, seed, etc.
• On small seeds and/or high rates, if population
monitor consistently indicates a lower population
than the GP Controller Console, contact monitor
manufacturer for performance specs for that application.
6. GPS signal is not being received by SiteMate:
• make sure GP Controller Console is set to VR
Mode.
• verify that GPS serial port (which is also the docking port) is not set to PC connection only (Start/
Settings/Communications/PC Connections-check
GPS settings in Configure/Settings/GPS settings/
COM (typically COM1, 4800 Baud, 8 data bits,
Parity None, and Stop Bits 1)
• double-check all cable connections
• Click Data tab to view GPS details
3. Rx rate appears on SiteMate but not on GP Controller Console.
• check Nominal rates on both the SiteMate (SiteMate Settings, Step 4), and on the GP Controller
Console (GP Settings, Step 2) These must be set
to the same number.
4. Rates on GP Controller Console and on SiteMate
do not match.
• check Nominal rates on both the SiteMate (SiteMate Settings, Step 4), and on the GP Controller
Console (GP Settings, Step 2) These must be set
to the same number.
• Re-check GP calibration number, with metering
wheel and row spacing.
• The recipe rates from SiteMate are in 4% increments. If the two rates are within this 4% range,
the units are operating normally.
• Check the Conversion number (SiteMate Settings,
Step 2). If the recipe requires a target conversion
number, i.e. the recipe is for 25 which means
25,000 seeds/acre, the target conversion number
will be 1000. In this case the Nominal Rate in
SiteMate and the GP Console should be near
25,000. See SiteMate Settings, Step 4 for calculating Nominal Rate.

Maintenance
As with any hydraulic system, contamination is
the most common cause of performance problems and pre-mature wear. Make a special effort
to properly clean quick couplers prior to attaching
the hoses to tractor.
1. Filter: All fluid is filtered through the high pressure filter (PN 18574) and it will provide protection to the hydraulic components of your
drive if properly maintained. It is equipped
with a pop-out indicator to alert that the replaceable element is clogged, and should be
changed immediately if this situation occurs.
Normal service life of the element will vary
based on the precautions that you take to
minimize contamination at the couplers and
routine service of the tractor filtration.
To change the element:
Refer to Figure 104
1. Un-screw lower canister from filter, catching
and disposing of used fluid.
2. Remove and discard element.
3. Install new element (PN 19856)
4. Clean canister threads and lube o-ring with
hydraulic fluid, then re-install.
Element
Refer to Figure 105
5. Re-set pop-out indicator if necessary.
It is a good idea to keep a filter element on hand,
and we recommend changing at a minimum on an
annual basis.
6. Between planting seasons, store cab console
inside in a relatively stable and dry environment.
22736
Figure 104
Pop-out
indicator
7. Avoid direct spray from high pressure washers on the motor encoder and the external
controller box. These units are sealed from
normal moisture, but high pressure could inject water into the housing.
8. Keep electrical connects free from dirt and
grease. It’s a good idea to occasionally spray
the terminals with contact cleaner to ensure
proper connection.

Troubleshooting
Drive will not rotate: (see Troubleshooting Flow Chart and Electronics Overview)
1. Check cab console:
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.
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 (PN 27857) to check power out of cab console. Install tester on
round 7-pin power/com 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 (PN 27859) to test power and communication to external
controller. WARNING: 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/com cable before powering the Cable
Continuity Tester - remove before reattaching power/com 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/com cable. Reattach power/com cable to cab console and external controller.
d. If power/com 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 (PN 27859) isn’t available, check cable with voltmeter at connection at
control module.
3. Test Relay inside external controller:
a. Use Relay Output Tester (PN 27860) to test relay inside external controller. Install tester to weatherpak 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 alarm
does not sound, relay or external controller may need to be replaced. Call Service Department.
4. Check hydraulics:
a. Check to see if 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 connected to tractor remotes.
d. Inadequate system pressure. Place pressure gauge at filter and check reading. If system pressure
is below tractor specifications, check system.
e. Power solenoid directly: DANGER: RAPID DRIVE ROTATION MAY OCCUR AND CAUSE SERIOUS INJURY. KEEP CLEAR OF DRIVE AREA.
i. Disengage hydraulics.
ii. Reduce flow to 30-50%.
401-182M
7/12/2005
Veris Drive Operating Instructions 93
iii. Power solenoid directly by connecting power weather-pak connector to solenoid weatherpak connector. If drive doesn’t rotate, Proportional Coil (PN 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
wedged in meter, frozen bearings, misaligned chains, or swelled grain in meter. 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):
a. No signal from speed sensor - check connection at sensor and at drive controller.
b. Excessive gap between wheel sensor and sensor plate - readjust to .030.
c. Use Speed Simulator (PN #27858) to troubleshoot speed loop. Leave tractor stationary and
drive hydraulics do not need to be engaged.
d. Test speed sensor and hall effect sensor; replace sensor if simulated speed appears on cab
console.
e. Test speed cable between speed sensor and hall effect module; replace cable if simulated
speed appears on cab console.
f. Test hall effect module and cable to external controller; replace module and cable if simulated
speed appears on cab console. If speed does not appear with speed simulator, 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 fluctuating 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 chain on row unit.
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, wheel pickup sensor, hall effect module. If steady speed
does not appear with speed simulator, external controller may need replacement. Call Service
Department.
b. Check radar gun angle.
c. Check gap between wheel sensor and pickup plate.
d. Check power to system < 12 volt 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 headleads, 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 calibration procedure if necessary.
b. Check to make sure that your desired rate is within the range of the meter that is installed.
7/12/2005
401-182M
94
1625
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 sprocket combinations; see Assembly and Parts Manuals for the planter you are operating (30P and 40P models).
f. 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 rerun calibration procedure if necessary.
b. Ensure that you have installed the correct seed meter.
c. Check sprocket combinations; see Assembly and Parts Manuals for the planter you are operating (30P and 40P models).
d. Check speed shown on cab console against other speedometer - tractor, planter monitor. 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 (PN 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:
13. If the time to run for calibration is less than 4 seconds, the cab console will display TIME TOO
LOW. Pressing the FUNCTION key 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 key will bring up the ENTER
TARGET AMOUNT screen. The target should be lowered to decrease the calibration time.
14. While rate calibration is running, one of four error messages may be displayed:
Message
Cause
Solution
COMM TIMEOUT
Power to or communication with the external
controller was interrupted
during calibration.
Check power and communication connections
from the cab console to
the external controller
and rerun calibration.
TIME OVER LIMIT
The external controller
ran too long in calibration.
Rerun calibration. If the
same message appears,
call technical support.
USER TERMINATED
The engage key was
pressed during calibration.
Rerun calibration.
CALIBRATE ERROR
The drive did not turn
when calibration began.
Check encoder cable
and connection, solenoid cable and connection, and hydraulic lever
position.
Pressing FUCTION will exit rate calibration from these error screens.
