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.

1. Make sure block mount of the spring linkage
(2) is in the lower mount hole for planting in
bedded irrigation. The upper hole is for nonbedded ground.
2. Set spring linkage length. Turn spring linkage
to shorten or lengthen as necessary. Initially
set length to 6 1/8 inches between pin centers
to achieve the 24-inch dimension mentioned
above. When adjusting the linkage length, remember:
• Lengthening linkage raises drill.
• Shortening linkage lowers drill.
3. Level drill with top three-point link.
Refer to Figure 6
NOTE: When drill is level, parallel links will be
running slightly uphill towards the front.
The 1-inch dimension shown is a general dimension that will vary with planting conditions.
IMPORTANT: Make sure the opener mount is

Adjustments
Side Gauge Wheels for 20 and 25 Series
Openers
Refer to Figure 18
The side gauge wheels have two, interrelated adjustments:
• angle of side gauge wheel, and
• distance between side gauge wheel and row unit disk.
Refer to Figure 19
Adjust side-gauge-wheel angle so wheels contact row unit disks
at bottom of wheel at 2” planting depth.
At the same time, keep side gauge wheels close to opener disks
so openers do not plug with soil or trash but far enough out so
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 remove shims as needed.
DO NOT ADJUST BEARING THAT WILL ADJUST

Opener Down Pressure
Refer to Figure 21
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 pressure to cut the seed trench
and maintain proper soil-firming over seed. Excessive opener down force will lead to premature
wear on opener components.

2. Raise the opener high enough that the hole
for the pin is above the lower parallel arm.
This can easily be done by placing a small
block below the disc blades and setting the
drill down upon it.
3. Insert locking pin through both holes and lower the opener allowing the pin to rest on the
top of the lower parallel arm.
NOTE: Do not pin the opener while it is in the
lowered position. If the pin is inserted below
the parallel arm it WILL damage opener soon
after planting begins.

Adjusting Finger Pick Up Meter
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 meter.
General Planting Tips
1. Optimum planting speed is 4 1/2 to 5 mph. Excess speed results in poor spacing performance due to seed tube bounce. Excess speed
may also result in improper depth control due to
opener bounce.
2. Always pay attention to your drill monitor. Compare actual seed usage to your estimates.
Figure 76
Adjustments
22872
49
3. Fine-tune your drill 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 opener itself.
Brush
Refer to Figure 77
The adjustable brush provides additional flexibility
to accommodate a wide range of seed sizes. Use a
flat-head screwdriver to gently rotate brush into position. Use general guidelines in the table below to
adjust brush position to your seed size and shape.
The numbers listed correspond to the numbers
printed on outer housing of the 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!

Checking Volumetric Seeding Rate
The seed charts are based on cleaned seed and
11L 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 holdseed 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.
6. Using the chart on the next page, select your
row spacing and determine the correct number of revolutions per acre. Turn drive gauge
wheel the selected revolutions for your row
spacing. Check in box 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 poundsper-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.
• Refer to “Troubleshooting” on page 59.
Equations for calibrating volumetric seeding rate:

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, according to the table, for the
row spacing in the planted area.
5. 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 9 1/2-inch row spacing drill, according to ,
three rows must be counted. Measure 18’ 4” 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:
If you have a Twin Row 30" spacing drill, according to
the chart, 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 170 by 200.
170 x 200 = 34,000 seeds per acre.
NOTE: Both rows of the Twin Row count as one
row.
6. If 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 160.
• Refer to Troubleshooting in on page 59.
Seed Rate Charts
Seed rate charts begin on page 104. 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 transmission sprocket reference.
NOTE: USE 1/200 ACRE FOR POPULATIONS LESS THAN 100,000 SEEDS/ACRE.
USE 1/1,000 ACRE FOR POPULATIONS ABOVE 100,000 SEEDS/ACRE.

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 drill
when folding or unfolding the markers.
!
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.

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.
IMPORTANT: 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.
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.
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 78
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.
Folding Speed with Sequence Valve
Refer to Figure 79
If markers are tied together with an optional sequence valve (P/N 113-466A), 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.

Marker Chain
There are two, interrelated adjustments for the
marker chain. Make these adjustments in the following order.
Refer to Figure 81
1. Lifting Slack. With marker unfolded, back fullthreaded adjustment bolt (1) down until head
extends as little as possible. Slowly fold marker
while observing disk. If marker disk slides
across ground more than a foot before chain
and linkage lifts it up, the chain is too long.
Shorten chain one or two links by moving clevis
(2). Check adjustment by repeating folding process.
If chain is too short when marker is unfolded, it
will prevent end of marker from dropping into
field depressions, causing skips in your marker
line. Correct this condition by lengthening chain
one or two links at clevis (2).
2. Folding Slack. Fold marker. Use full-threaded
adjustment bolt (1) to take slack out of chain
while marker is folded. Extend bolt until there is
no chain slack. Lock bolt in this position by tightening nuts (3) on either side of upright channel

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 drill for several hours, check all
bolts to be sure they are tight.
2. Lubricate areas listed under “Lubrication”,
page 75.
3. Adjust idlers to remove excess slack from
chains. Clean and use chain lube on all roller
chains as needed.
4. Inflate tires as specified on “Tire Inflation
Chart”, page 160.

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.
Refer to Figure 96
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.
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.
Precautions
1. Make sure the finger set is properly torqued against
the backing plate. Improperly torqued finger sets may
disrupt seed singulation.
2. Avoid seedtreatments, 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 23. 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.

bearing by rotating wheel. If the bearings are rough,
inspect and replace if necessary.
2. The side wheels are preset at the factory, however
because of normal wear it may become necessary
to make adjustments so the wheel remains close to
the disk. To prevent plugging loosen clamp bolt (7)
and slide arm inward to take up gap between side
wheel and disk blade. If more adjustment is needed
go to step 3.
3. Remove bolt (10) and wheel (2). Remove shims (1)
from the inside of the wheel (2) and place them on
the outside of the wheel. Always place the shims removed from the inside to the outside. When installed, the wheel should turn freely and not hit the
arm at the curve. Do not add any more shims than
necessary.
4. Disassemble side gauge wheel arm (3) from unit.
Remove bushing (4) from sleeve (5) and check
bushing for wear. Replace bushing if necessary.

2. The side wheels are preset at the factory, however because of normal wear it may become necessary to
make adjustments so wheel remains close to the disk.
To prevent plugging loosen clamp bolt (7) and slide
arm inward to take up gap between side wheel and
disk blade. If more adjustment is needed go to step 3.
3. Remove bolt (10) and wheel (2). Remove shims (1)
from the inside of the wheel (2) and place them on the
outside of the wheel. Always place the shims removed
from the inside to the outside. When installed, the
wheel should turn freely and not hit the arm at the
curve. Do not add any more shims than necessary.
4. Disassemble side gauge wheel arm (3) from unit. Remove bushing (4) from sleeve (5) and check bushing
for wear. Replace bushing if necessary.
5. When reinstalling side gauge wheels, align tab on hex
adjustment (6) with notch in bushing. Replace bolt and
tighten.
6. Adjust side gauge wheels. Refer to “Adjustments,”
page 26.

NOTE: Failure to replace the shear bolt with a
grade 2 bolt can cause marker damage.
If grease-seal cap for marker-disk-hub bearings is
damaged or missing, disassemble and clean hub.
Repack with grease and install a new seal or
grease cap.
Storage
Store the drill where children do not play. If possible, store the drill inside for longer life.
1. Unload seed box:
• Place tarp under drill or a bucket under each
seed meter.
• Use a 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.
2. Thoroughly clean seed and seed-treatment
residue from boxes and seed meters.
3. Remove seed meter wheels. Store flat and
out of the weather.

Operations
Before going to the field:
1. Once calibration procedure above has been
followed, Console will store calibration and rate
information until new information has been entered.
Refer to Figure 128
2. Turn on Console by pressing On/VR key.
Pressing On/VR key twice will put 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:
• 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 129
1. Turn on Controller Console by pressing On/VR
key. Green light above On/VR key will illuminate when power is on. Pressing On/VR key
twice will put the unit in VR mode. VR will appear on screen along with 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 Up/Down arrow
keys. This will change Controller to the rate you
select manually. To return to VR, simply touch
On/VR key to toggle back to VR mode.
3. Engage 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.

• Case-IH Magnum tractors: Lock lever forward
in detent position. You may need to turn up detent pressure to 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.
4. Press Engage key to activate drive. Green light
above Engage key will illuminate.
NOTE: If you do not move within 10 seconds, the

5. Console display shows two numbers while operating:
“Set” rate is the rate you tell the system to plant, and
“Out” rate is the calculated rate based on the actual
rotations of the drive. The “Out” reading monitors the
drive system; it doesn’t monitor 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.
6. If “Out” rate varies from the “Set” rate by more than
20%, an audible alarm will sound.
7. If Controller is powered directly from the battery or via
unswitched power port, make sure to power Console
off when tractor is shut down. This prevents tractor
battery drain.
Veris Drive Sprocket Change
For proper operation on finger meters (high range) it will
be necessary to switch from 12 tooth to 24 tooth Veris
Drive sprocket.
Refer to Figure 130
2. Slide 12 tooth sprocket (2) and 24 tooth sprocket
(3) towards Veris Drive until they rest against inside locking collar (4).
3. Replace spacer (1) on shaft between 24 tooth
sprocket (3) and outside locking collar (5). Hold
spacer in place with retaining clip. Install Veris
Drive chain. Tighten chain idler.
4. Reverse steps to switch back to 12 tooth sprocket (2) when operating 20 and 25 series meters.
NOTE: Make sure and switch to the proper sprocket
on both drives.
1. Loosen chain idler. Remove Veris Drive chain. Pull retaining clip from sprocket spacer (1). Remove spacer
(1) from Veris Drive shaft.

Plains Precision Population Controller QUICK
REFERENCE GUIDE
(Create a .shp recipe file in FarmWorks Site Pro, SMS
2.0, SSToolbox, or other software thatwill create a .shp
file, and transfer it to SiteMate.)
SiteMate Settings: (version 8.12)
1. Select CONFIGURE Tab. Select SETTINGS. Select VARIABLERATE 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 theconversion 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.
5. Under FILE, Open VRT and select the Rx Map
(recipe) for the field. Press the SETUP button and
select the GP PPC controller option that you have
set up using these Settings Instructions.
6. Press GO. The Rx rate window shows the rate that
is being sent to the GP Precision Population Controller. The APPLIED window shows the rate that
the GP Controller is applying.

Troubleshooting GPS-based Seeding 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.
3. Rx rate appears on SiteMate but not on GP Controller Console.
• make sure GP Controller Console is set to VR
Mode (seeFigure 129, page 90)
• double-check all cable connections
• check Nominal rates on both the SiteMate (SiteM-
ate Settings, Step 4), and on the GP Controller
Console (GP Settings, Step 2) These must be set
to the same number.
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:
• 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)
• Click Data tab to view GPS details
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 (SiteMateSettings,
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 131
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.
Refer to Figure 132
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.
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.
