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.
Important Safety Information
1
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.

Talc Lubricant (P/N: 821-046C)
Great Plains “Ezee Glide” talc is 100% natural talc.
Use only Great Plains “Ezee Glide” brand talc for
optimum seed flow.
“Ezee Glide” Talc lubricant is mandatory for all
seeds, especially treated or inoculated seed.
Recommended usage:
For clean seeds sprinkle (1) one cup of talc per 3 bushels of seed. Adjust this rate as necessary so all seeds
become coated while avoiding an accumulation of talc in
the bottom of the hopper.
For seed with excessive treatment, or for humid planting
environments, increase the rate as needed for smooth
meter operation.
Thorough mixing of seed and added lubricant is required. DO
NOT use hands or any part of your body to mix talc
lubricant.
Graphite Lubricant (P/N: 821-042C)
For Milo Planting Only
Powdered graphite must be mixed with the milo seed in
combination with talc for proper seed singulation.
Recommended usage:
For clean seeds sprinkle (1) one cup of graphite per 9
bushels of seed.
For seed with excessive treatment, or for humid planting
environments, double or triple graphite rate as needed.
Do not use hands or any part of your body to mix graphite
lubricant.

Transporting
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. Check that your tractor has enough
ballast to handle the weight of the drill. Refer to your
tractor operator’s manual for ballast requirements.
NOTE: For transporting with drill attached to a
hitch, refer to your hitch operator’s manual.
Before transporting the drill, follow and check
these items:
Unload seed box. Unload seed box before transporting if at all possible. To do so:
Operating Instructions
23
• Place tarp under drill or a bucket under each
seed meter.
• Use large bucket to empty box as much as
possible. Make sure sliding seed tubes are in
the open position. Open seed meter clean out
to empty seed out of sliding seed tube and
meter.
The drill can be transported with a full box of grain,
but the added weight will increase stopping distance and decrease maneuverability.
NOTE: To maintain steering control, you may
need to add ballast to your tractor front end.
Refer to your tractor operator’s manual for ballast required.
Road rules. Comply with all federal, state and lo-
cal safety laws when traveling on public roads.
Refer to Figure 12

Opener Down Pressure
Refer to Figure 13
Opener springs provide the down pressure necessary for opener disks to open a seed trench.
The springs allow the openers to float down into
depressions and up over obstructions.
You can adjust down pressure individually for
each opener. This is useful for penetrating hard
soil and planting in tire tracks.
Use enough down pressureto cutthe seed trench
and maintain proper soil-firming over seed. Excessive opener down force will lead to premature
wear on opener components.
Refer to Figure 14
To adjust down pressure, use adjustment tool

A press wheel attached to each opener body controls seeding depth. To maintain consistent depth,
the relationship between the bottom of the opener
disks and press wheel is fixed upwardly.
The press wheels also close the seed trench and
gently press soil over seed. To provide consistent
soil firming, press wheels are free to move down
from normal operating position. This maintains
pressing action even if opener disks encounter
obstructions or hard soil.

At the same time, keep the side gauge wheels close
to the opener disks so openers do not plug with soil
or trash but far enough out so the disks and wheels
turn freely.
• If contact point is between 4 to 8 o’clock but
distance to tire is not correct, then add or re-
move shims as needed. DO NOT ADJUST
BEARING AS THAT WILL ADJUST WHEELTO-DISK CONTACT AREA ONLY.
Refer to Figure 23
To adjust Wheel-to-Disk contact area of side gauge
wheels:
1. Raise drill slightly to remove weight from side

Checking Volumetric Seeding Rate
The seed charts are based on cleaned seed
and 9.5L x 15, rib implement tires. Factors including foreign material, seed treatment,
seed size, seed weight, field conditions and
tire pressure will affect seeding rate. Set and
check the seeding rate, then readjust the rate
as necessary.
1. Record the weight of an empty container
large enough to hold seed metered from
three meters for one acre.
2. Place several pounds of seed over three
seed meters on an outside end of the drill
box.
NOTE: If drill box is full, shut off sliding
seed tubes to all but three meters on an
outside end.
3. Raise drill off ground.
4. Turn gauge wheel a few turns to fill
meters with seed and until seed drops to
ground from all three openers.
5. Place a container under the three openers to gather seed as it is metered.

to make sure seed tubes have plenty of
seed covering them.
7. Weigh measured seed. Subtract initial
weight of empty container. Divide by
three for the amount metered by each
meter, then multiply by the number of drill
openers for the pounds-per-acre seeding
rate.
8. If seeding rate is different than desired:
• Double check transmission sprocket
and drive range sprocket combinations.
• Check for meter malfunction.
• Check for correct seed meter wheel.
• Check that all three rows are getting
seed.

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 below, determine how many
rows need to be counted.
4. Measure a distance of 17ft 5in- in the planted
area. If 20-inch row spacing is being used,
measure a distance of 26ft 2in- 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 200
if measuring for 1/200 acre or 1,000 if measuring for 1/1,000 acre. This is the plant population in seeds per acre.
Example 1:
If you have a 10-inch row spacing drill, according
to the table below, three rows must be counted.
Measure 17ft 5in and count the number of seeds
in three rows. If the number is, for example, 180,
multiply 180 by 1,000.
180 x 1,000 = 180,000 seeds per acre.
Example 2: Twin Row
If you have a Twin Row 30in- spacing drill, according to the table below, both rows of the twin row
must be counted. Measure 87’1” and count the
number of seeds in the parallel row. If the number
is, for example, 170, multiply by 200.
170 X 200 = 34,000 seeds per acre
NOTE: Count Twin Row as one row.
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
tires. Refer to “Tire Inflation Chart” on page
128.
• Refer to Troubleshooting on page 47.
Seed rate charts
Seed rate charts begin on page 96. The charts give
transmission sprocket combinations and drive
range sprocket combinations for each row spacing,
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.

Marker Adjustments
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.
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.
Adjustments

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.
Check that tractor hydraulic reservoir is full.
1. 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.
Never bleed an O-ring fitting. Instead, bleed a nearby
pipe or JIC fitting.
2. With tractor idling, activate tractor hydraulic
valve until oil seeps out around a loosened fitting. Tighten that fitting.
JIC fittings do not require high torque. JIC and Oring 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.
3. 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.
Folding Speed with Needle Valves
Refer to Figure 46
A needle valve controls the folding speed of markers that areplumbed separately. 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.
Refer to Figure 47
Folding Speed with Sequence Valve
If markers are tied together with an optional sequence valve, adjust folding speed with hex
adjustment screws on the sequence-valve body.
There is one adjustment screw for raising speed
(1) and one for lowering speed (2). Identify adjustment screws by markings stamped in valve body.
With tractor idling at a normal operating speed,
adjust marker folding to a safe speed. Turn adjustment screws clockwise to decrease folding speed
and counterclockwise to increase folding speed.
Excessive folding speed could damage markers
and void the warranty.
After adjusting the folding speed, tighten jam nuts
on hex adjustment screws to hold settings.

Markers
Hydraulic markers are available. The units have a
cast hub, tapered roller bearings and a bolt-on
blade to leave a mark for you to follow on the next
field pass. Each marker requires a hydraulic circuit for operation. A sequence valve is available
so markers can be operated on the same hydraulic circuit.
For information on how to operate the markers, refer to “Marker Operation”, page 22. For
information on transporting the markers, refer to

Important Safety Information
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.

Calibration - Speed
In order for the Controller to meter the proper amount of material, it must have an accurate field speed input. Speed
may be supplied by radar or by wheel pickup sensor. For the Controller to convert the pulses that it is receiving from
the speed input into accurate speed, it must be calibrated. To calibrate the Controller for speed, press the Function
key until the screen appears, as shown in Figure 1.
Figure 1. Speed calibration screen.
Figure 2. Press up to initiate new speed calibration routine; press down to restore factory default settings.
Set two flags 400’ apart (100 meters if in metric mode). Begin driving at a normal field speed; when the tractor passes the first flag, press engage. See Figure 3 on the next page. The display will show the distance traveled as shown
in Figure 4.

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.
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. See Figure 3.
NOTE: For units with PN 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 difference:
a. Volumetric: use extreme caution when performing this calibration to prevent injury due to drive entanglement. Al-
so, turn drive gauge wheel with a consistent speed of at least 30 rpm for maximum calibration accuracy.
b. 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 (minimum 3 mph) during the calibration distance.
In field:
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. See Figure 1. 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).
Figure 23. Main Operating Screen Set on VR mode.
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.
81
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.

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 distance
from the GPS antenna to the Great Plains Mfg, Inc meter. 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

Troubleshooting GPS-Based Seeding with SiteMate
87
1. No Rx rate appears on SiteMate
• Has field been selected? Select VRT file.
• 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
3. Rx rate appears on SiteMate but not on GP Controller Console
• Make sure GP Controller Console is set to VR Mode.
• Double-check all cable connections.
• 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.
5/6/2010
• 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 Setting, Step 4 for calculating Nominal Rate.

1. Population Monitor rate does not match GP Controller Console
• Make certain that SiteMate and GP Controller Console agree. If not, see Troubleshooting
Step 4 above.
• 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 indicated a lower popu-
lation than the GP Controller Console, contact monitor manufacturer for performance specs
for that application.
2. GPS signal is not being received by SiteMate
• 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 COM 1, 4800 Baud,
8 data bits, Parity None, and Stop Bits 1).
• Click Data tab to view GPS details.

Troubleshooting GPS-Based Seeding with PF3000
1. No Target Rate appears on the PF3000
• Has field been selected? Select target file (see PF3000 settings, Step 4).
• Check recipe to verify that it is valid.
• If recipe calls for zero rate as the default, do you have GPS signal, or are you outside of field?
2. No Actual Rate appears on PF3000
• Actual rate cannot be logged using the PF3000 with the Great Plains Precision Population Controller.
3. Target Rate appears on PF3000 but not on GP Controller Console
• Make sure GP Controller Console is set to VR Mode.
• Double-check all cable connections.
• Check Nominal Rates on both the PF3000 and on the GP Controller Console. These must be set to the same number.
4. Rates on GP Controller Console and on PF3000 do not match
• Check Nominal Rates on both the PF3000 and on the GP Controller Console. These must be set to the same number.
• Re-check GP calibration number with metering wheel and row spacing.
• The recipe rates from the PF3000 are in 4% increments. If the two rates are within this 4% range, the units are op-
erating normally.
• Check the target conversion number (PF3000 Settings, Step 6). 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 on the PF3000 and on the GP Console should be near 25,000. See PF3000 Settings, Step 5 for calculating
Nominal Rate.
5. Population Monitor rate does not match GP Controller Console
• Make certain that PF3000 and GP Controller Console agree. If not, see Troubleshooting, Step 4 above.
• 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.
• When planting small size seeds and/or at high rates, if population monitor consistently indicates a lower population
than the GP Controller Console, contact monitor manufacturer for performance specs for that application.
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:
a. Unscrew lower canister from filter, catching and disposing of used fluid.
b. Remove and discard element.
c. Install new element (PN 19856)
d. Clean canister threads and lube o-ring with hydraulic fluid, then re-install.
118-732M
5/6/2010
Page 93
a. 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.
1. Between planting seasons, store cab console inside a relatively stable and dry environment.
2. 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.
3. 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
Veris Drive Operating Instructions
Element
91
b. No power to cab console - check with voltmeter.
c. Upper line (set) is visible but no lower line (out rate and
speed) on display: move to Communication troubleshooting
below.
d. 1 or 10 amp fuse on power cable may be blown.
e. Engage button is not on - check to see if green indicator light
is on.
f. 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 weather-pak
solenoid connector from external controller. With tractor engine off, start drive calibration function. Auditory alarm should buzz for 1.5 seconds when drive is engaged in calibration mode. If 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 be-
low tractor specifications, check system.
e. Power solenoid directly: DANGER: RAPID DRIVE ROTATION MAY OCCUR AND CAUSE SERIOUS IN-
JURY. KEEP CLEAR OF DRIVE AREA.
i. Disengage hydraulics.
ii. Reduce flow to 30-50%.
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):
Rapid drive rotation may occur and cause
serious injury. Keep clear of drive area.
118-732M
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 hydrau-
lics 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 con-
troller; 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.
Rapid drive rotation may occur and cause
serious injury. Keep clear of drive area.
5/6/2010
Page 95
Veris Drive Operating Instructions
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 mani-
fests itself in speed loop.
8. Drive shuts off while planting:
a. If it occurs after 20 seconds of not planting, such as turning on headlands, operation is normal safety
shutoff (on units with radar speed signal).
b. Check setting of speed signal interrupter switch - reposition as necessary to keep actuator from dis-
engaging while planting.
c. 1.5 second delay shutting off drive - causes: chain binding, inadequate hydraulics.
9. Drive will not achieve desired rate:
93
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.
c. Inadequate hydraulic flow. Adjust flow control to higher position. Check with flow meter if flow is sus-
pect.
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 higher, 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 com-
pressed 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.
