Singulated Planting Overview
The information in this section covers important setup
and checking information that applies to both:
Singulator Plus (wheel, at left in Figure 2) meters and
Finger Pickup meters (at right in Figure 2).
There are additional Sections for each meter. See also:
“Finger Meter Planting” on page 14 and
“Singulator Plus™ Meter Planting” on page 7.
Singulating planting employs the seed monitor in
“PLANTER CONTROL” mode. Volumetric planting uses
“GRAN SEED CONTROL” or “granular” mode, and is
covered at “Volumetric Meter Planting” on page 24.
Population Risk:
If the seed monitor is presently in GRAN SEED mode, follow
the setup instructions carefully. Switching between seeding
modes can cause some planter configuration values to be reset
to defaults that are incorrect for your planter.

Population Reference Information
Seeds per Unit
If only pounds/acre (kilograms/hectare) is known, obtain
the population count by multiplying the population weight
by the “Kernels per pound” value from the seed
container.
Example: Milo
Target rate:4.5 pounds/acre
Seed density:14500 seeds/pound
Population:= Rate x Density
= 4.5 x 14500, or:
65250 seeds/acre
Seed Spacing
If only seed spacing is known, use the tables on
pages 5, 6 and 54 to determine population.
1. For your crop, determine your intended population, in
seeds/acre or seeds/hectare. If you know only the
population, the charts on page 5 and 54 correlate
population to seed spacing for several row spacings.
2. For your crop, population and desired field speed,
verify the suitability and setup of your meter type,
and seed wheel part number or finger count.

3. Verify, and as necessary setup or update the
“Material” record for the singulated seed to be
planted.
The table at right lists the parameters that need to be
reviewed or set. Values in <angle brackets> are at
your choice or preference.
4. Verify, and as necessary setup or update the
“Channel” assigned to the planter’s hydraulic drive.
If the monitor resets to defaults, Gear Ratio may be
incorrect.
Count rows individually for “# Seed Rows”. A twin
pair (if both openers are in use) counts as 2 rows.
“Channel Width” is swath (number of active rows
times spacing between active rows), for example:
465 in = 31 rows x 15in per row.
For twin rows, count twin pairs and pair-to-pair
spacing, for example:
480 in = 16 twin pairs (32 rows) x 30 in pair spacing
5. In the Material Library screen, makes sure that the
Material (SOYBEANS in our example) is assigned to
the Channel (Ch 1 in our example) which controls
the planter’s hydraulic drive.
6. Perform a Valve Calibration for the control channel.
7. Switch the seed monitor from Setup/Configuration
mode to Operate mode. Load seed. Move the planter
to the field.
8. Verify your planting rate per the instructions in the
next topic. If the results are consistent with your
setup, plant the crop.

Checking Planting Rate
Although your seed monitor will report useful full pass
results, cautious practice includes manually checking the
seed rate early in the first pass.
The seed charts are based on cleaned and sized seed.
Extreme seed variations, foreign material and tire
pressure can materially affect planting rate.
Checking the rate also provides a double-check on your
population calculations and drive configuration.
The procedure is different for singulated seeding (this
page) and volumetric seeding (page 26).
Seed Rate Check Sample Size
(U.S. customary units. See page 53 for metric.)
Checking Singulated Rate
1. Using the table above, determine the length and
number of rows to check. For twin-row operation, a
pair of row units counts as one row.
2. Adjust the planting depth to shallow on that number
of rows units. Using center and wing-end row units
for measurement provides a more accurate
assessment of overall planter performance. Pick
center units outside wheel tracks.
3. Use bungees or wire to tie-up the press wheel
assembly on the tested row units, so that the seed is
not covered. Tie up both in a pair for twin-row.
4. Operate the planter for the distance in the table, plus
a few feet or meters for the press wheels to clear the
end of the sample distance.
5. Count the number of seeds in the test rows.
6. Multiply the total number of seeds counted by 200 if
measuring for1⁄
1
⁄
acre. This is the plant population in seeds per
1000
acre.
7. If the populated is substantially different than
expected, see “Troubleshooting” in the planter
Operator Manual.

Singulator Plus™ Meter Planting
Follow the steps in “Singulated Planting Overview” on
page 2. At step 2 on page 2, follow the instructions in this
section, which are specific to Singulator Plus™ meters
when used with singulating seed wheels.
Volumetric planting with Singulator Plus™ meters is
covered beginning on page 24. Singulated planting with
finger pickup meters is covered beginning on page 14.
Maximum recommended speed is 7 miles per hour
(11.3 kph), based on maximum meter rpms.
Excess speeds are known to deteriorate seed spacing
control and depth control.
For your crop, verify that you have the correct seed
wheels, and that your population and proposed field
speed are within limits for that wheel. See “Reading aSingulated Rate Chart” below.
When ordering seed wheels, note that there are different
part numbers for:
10HD/25P Series ( wheels) and
20P Series ( wheels).

Finger Meter Planting
Follow the steps in “Singulated Planting Overview” on
page 2. At step 2 on page 2, follow the instructions in this
section, which are specific to finger pickup meters.
Recommended maximum speed is 6 miles per hour (11.2 kph),
based on meter rpm limits.
Excess speeds are known to deteriorate seed spacing
control and depth control.
a. For your proposed ground speed, check that your
proposed population is within rpm limits for your 6- or
12-finger meters (this section, pages 15 and 77).
b. Set your meter brushes for your material (page 17).
c. If planting twin row, and indexing is desired, set the
stagger between the rows of each pair (page 19).
If you are planting indexed twin row, at “SingulatedPlanting Overview” step 8 on page 3, also check the
row-to-row seed spacing in each row pair. As necessary:
d. Adjust the stagger between pair rows using the
instructions beginning on page 22.

Finger Meter Brush Adjustment
The finger pick up meter has an adjustable brush.
The brush reduces or eliminates “doubles” (delivering
two seeds per finger), but if set too aggressively can
cause “skips” (delivering no seed on some fingers). As
needed, adjust for minimal doubles and skips.
Refer to Figure 6
The adjustable brush provides additional flexibility to
accommodate a wide range of seed sizes. Use lever
L
to gently rotate the brush into position.
The settings range from 1 to 5 with detents at each half
step, for a total of 9 detents. The factory default setting is
21⁄2. Although the numbers are molded into the meter
housing, only “1” and “5” may be visible. To ensure
consistency, rotate the lever fully counter-clockwise
L
(1), and count detents as you advance it to the desired
setting.
Use the general guidelines in the table at 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.
If there is a decal on your meter, its units are in pounds
per 80,000 seed bag. The table below includes seeds
per pound.

meters after purchase, there is some chance that
you may have previous model meters, adjusted by
screwdriver rather than lever. If so, rely on counting
detents to determine the setting. Not all have 9

Finger Meter Inserts
Refer to Figure 7
The backing plate is equipped with an “A” 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.
The identification of the insert type is molded into the
back of the insert.
Meter Performance Risk:
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 untreated seeds. If graphite must
be used, use Precision®Planting graphite or Great Plains
graphite which is less abrasive. Seeds with Maxi, Captan,
Cruiser, Poncho and similar treatments can benefit from
graphite. Use the amount recommended on the graphite
container, usually 1 tsp(5ml)/unit or 1 tsp/80,000 seeds.

Always store meters in a dry, secure place, with brush in
between two meter fingers. Moisture, temperature,
nest-building insects and rodents can create problems.
Always pay attention to your seed monitor and operating
manual. Monitor the amount of seed you are planting
compared to your expectations. Always investigate
abnormalities!

If you are planting:
• finger-metered,
• twin-row crops,
• at seed interval spacings above 61⁄2 inches (16.5 cm),
you can synchronize each pair of adjacent meters in a
twin row so that you achieve the maximum seed-to-seed
spacing between the units of the pair.
If you are planting:
- single-row,
- or with singulating meters,
- or a volumetric crop,
- or twin row with seed spacings below 61⁄2in (16.5 cm),
this section of the manual, and the sprocket indexing
charts, do not apply to your operations.

Sprocket Indexing Charts
1. For: your 6- or 12-finger meter, and your twin row
spacing (30in on this page) find your seed rate in the
Population column, or your seed spacing in the Seed
Spacing column. Seed spacing is seed-to-seed
within a single row of a twin row pair.
2. At the front/forward row unit of a pair, set the driven
(final) sprocket of the meter drive so that tooth
stamped #1 is straight up (TDC, 12:00 position).
3. At the rear/trailing row unit of the pair, set the driven
sprocket so that the tooth number at “Rear Meter” is
in the straight up 12:00 position.
These charts are in U.S. customary units. See page 78 for metric charts (70cm twin row).
Not Rate or Spacing Charts:
These are NOT seed rate or seed spacing charts. These are for

Indexing Fine Adjustment
If, after indexing, the twin-row side-to-side seed stagger
is substantially imbalanced, it is possible to make small
adjustments that may correct it. Imbalance can occur
over time as row unit chains wear and stretch.
The procedure is different for 6- and 12-finger meters.
If an adjustment is made, test it on one row pair before
adjusting the entire planter.
Before making any Indexing Adjustments:
• Check actual planted seed spacing. Seed Spacing is
found by measuring the distance between 25 correctly
planted seeds in one row and dividing by 24. (A visible
skip or double is counted as one seed.)
• Make sure the current front sprocket index is 1, and
the current rear sprocket index number matches the
number in the indexing chart for actual seed spacing
being planted.
6-Finger Meter Stagger Adjustment
Find your current indexing value row in the chart on
page 20.
Each (sprocket tooth) number directly above or below the
current rear meter sprocket setting in the right most
column of the seed indexing chart represents a small
movement of the rear row seed relative to the front row
seed.
Changing rear your sprocket to the next number up in the
chart retards, moving each rear row seed back a small
amount.
Changing rear sprocket to the next number down in the
chart advances, moving each rear row seed ahead a
small amount.
Example 1:
The 6 Finger, Twin Row 30in planting population is
32000 or 13.1in seed spacing. The chart setting for the
rear sprocket is [ 15 ]. Each rear row seed should fall
6.6in behind the front row seed.
If each rear row seed measures only 5in behind the front
row seed, reset the rear meter sprocket to the next
number up in the chart [ 12 ]. This moves the rear seeds
back to make the stagger closer to 6.6in.
Example 2:
The 6 Finger, Twin Row 30in planting population is
32000 or 13.1in seed spacing. The chart setting for the
rear sprocket is [ 15 ]. Each rear row seed should fall
6.6in behind front row seed.
If each rear row seed measures 9in behind the front row
seed, reset the rear meter sprocket to the next number
down in the chart [ 18 ]. This moves the rear seeds
ahead to make the stagger closer to 6.6in.

Volumetric Meter Planting
In Singulator Plus™ planting with volumetrica seed
wheels, planting rate is determined by:
• row spacing
• crop and seed variant
• meter wheel selection, and
• meter drive configuration (which relies on the “pounds
per meter revolution” data in the following tables).
There are no other adjustments, but to achieve the
desired rate, calibration is strongly recommended, and
there is a recommended range of meter rpms, which
affects the range of ground speeds, shown in the
following tables. The optimal rpm varies with meter
wheel and seed type.
Volumetric planting uses “GRAN SEED CONTROL” or
“granular” mode. Singulated planting employs the seed
monitor in “PLANTER CONTROL” mode, and is covered
at “Singulated Planting Overview” on page 2.
Figure 11
Volumetric Seed Wheels
29344
Population Risk:
If the seed monitor is presently in PLANTER CONTROL mode,
follow the setup instructions carefully. Switching between
seeding modes can cause some planter configuration values to
be reset to defaults that are incorrect for your planter.
1. For your crop, determine your intended population, in
pounds/acre or kg/hectare.
2. For your crop, population and desired field speed,
verify the suitability of your seed wheel at the
intended population and field speed. See “Readinga Volumetric Chart” on page 28.
Note: If a rate/speed table is not provided for your crop,
that crop has not yet been tested on the YP30/40
Planter planter.

3. Verify, and as necessary setup or update the
“Material” record for the granular seed to be planted.
The table at right lists the parameters that need to be
reviewed or set. Values in <angle brackets> are at
your choice or preference.
Note: “Spreader Constant” is a critical value, and must be
established by calibration. Do not plant with the
default value for this item. No entry is require if
calibration is planned prior to planting (page 26).
Otherwise, enter a value from a previous
calibration of the same wheels, seed and seed
variety. If these is any chance that the seed batch
varies from the prior calibration, re-calibrate.
4. Verify, and as necessary setup or update the
“Channel” assigned to the planter’s hydraulic drive.
If the monitor resets to defaults, Gear Ratio may be
incorrect.
Count rows individually for “# Seed Rows”. A twin
pair (if both openers are in use) counts as 2 rows.
“Channel Width” is swath (number of active rows
times spacing between active rows).
5. In the Material Library screen, makes sure that the
Material (WHEAT HRW in our example) is assigned
to the Channel (Ch 1 in our example) which controls
the planter’s hydraulic drive.
6. Perform a Valve Calibration for the control channel.
7. Switch the seed monitor from Setup/Configuration
mode to Operate mode. Load seed. Move the planter
to the field.
8. Verify your planting rate per the instructions in the
next topic. If the results are consistent with your
setup, plant the crop.

Calibrating Volumetric Rate Spreader Constant
Calibration (which determines the Spreader Constant) is
required for accurate planting of volumetric (GRAN)
seed.
Volumetric seeds are planted at much higher populations
than singulated seeds, and are measured in pounds or
kilograms (rather than seeds) per acre or hectare. The
seed tube sensors are generally not capable of counting
every seed at typical volumetric rates (although they do
report blockage).
For volumetric calibration, the tractor must to be hitched
to the planter, and providing electrical power. Leave all
hydraulic circuits in Neutral until instructed to activate the
drive circuit.
1. You will need a light weight container for each row
sampled, and a scale that is accurate at the
expected sample weight. Great Plains recommends
using enough rows and/or revolutions to generate a
sample of about 10 pounds (4.5 kg), ideally:
• Use at least two rows.
• Use no fewer than 5 meter revolutions.
2. Determine the meter revolutions needed. The
following equation gives the number of meter
revolutions needed to meter 10 pounds. The table on
page 44 provides approximate pounds (and kg) per
revolution of each wheel and seed.
Hydraulic circuits are active for calibration. Unexpected
movement of planter mainframe, sections, markers, and
unexpected activation of devices connected to the auxiliary
hydraulics can occur if controls are not correctly pre-set and
left untouched. Keep everyone clear of planter while
calibrating.
Population Risk:
Calibrate - Planting volumetric seed based only on chart
data is risky. Your material, and your field results, can vary
substantially from the test material used to generate the
charts. Great Plains strongly recommends calibration.
For Example
4 containers each weighing:8 oz.
8 oz x 4 = 32 oz
For example:planter: YP4025-3115, 15 rows
wheel: 403-118D WHEAT NARROW
crop: Hard Red Winter wheat
PoundsPerRev:0.078
RowsSampled:4
10 ÷ (4 x 0.078) = 32
Enter 32 for “# Meter Revs” at step 11 on page 27.
3. Configure the seed monitor for the planter and crop
(material). If the seed density is not known,
use 1 lb/cu-ft or 1 lb/bu.
4. Consult the rate chart for the crop. Note the allowed
Meter RPM range for the intended seed wheel and
planting speed (see “Reading a Volumetric Chart”
on page 28).
5. Select the section and rows to be sampled.
6. Use the clutches to disconnect the other sections of
the planter. This eliminates the need to uncouple the
meters on those sections.
7. Disengage the drive couplers on all other meters on
the test section, except the meters to be used for
testing.

8. Raise the planter, and install the lift cylinder
transport locks. Leave the tractor hydraulic system
active.
9. Activate the hydraulic drive circuit. Command the
planter seed monitor to:
FILL DISK
10. Place a collection bucket under each test meter’s
seed tube.
11. In the Spreader Constant Calibration screen, enter
the “# Meter Revs” and press the [Start] button.
12. Weigh the containers plus seed (GrossWeight).
Subtract the empty container weights to obtain the
net weight.
NetWeightGrossWeightContainerWeight–=
13. The seed monitor assumes that all rows were tested.
If you tested fewer (commonly the case), scale the
sample size to planter-wide:
14. Enter the Amount Dispensed.
The seed monitor computes a new Spreader
Constant.
Note: If the net weight of the metered sampled was
dramatically different than expected, run another
calibration to validate or revise the new spreader
constant.
15. Re-engage couplers on disabled meters.
Moving Chain Hazard:
Shafts turn and chains move as soon as the [Start] softkey is
pressed on the seed monitor. Set up collection containers so
that they may be unattended. Keep all persons clear of the
planter while calibrating.
For example:ContainerWeight: 2 lbs
GrossWeight: 12.88 lbs
12.88 - 2 = 10.88
NetWeight:10.88 lbs
For example:NetWeight: 10.88 lbs
RowCount: 31
RowsSampled: 4
(10.88 x 31) ÷ 4 = 84.34 lbs

Reading a Volumetric Chart
1. Using the rate range charts on pages 29-43 or
61-75, find the chart for your seed, in this example,
Hard Red Winter Wheat.
2. Find your row spacing at right side of the chart,
10 inch single row in this example.
3. The speed and rate ranges are determined by
allowable meter rpms. Enter the Meter RPM limits in
the seed monitor to set alarms for operations that are
too slow or too fast.
4. With your desired seed population in mind (for
example, 110 pounds/ac), note at which field speeds
that population remains in range. These are the
ranges, in pounds per acre, within which the seed is
metered accurately. In this example, speeds of 4 to 6
mph are in range for the “NARROW” wheel, and 6 to
8 mph are in range for the “WIDE” wheel. Assuming
that a slower speed is desired, choose the
“NARROW” wheel.
5. Verify that you have the correct seed wheel for the
chart, WHEAT NARROW in this example. When
ordering seed wheels, note that there are different
part numbers for:
10HD/25P Series ( wheels) and
20P Series ( wheels).
6. For Rice, note that a Flow Gate (p/n 817-529C) is
required inside each seed meter. Rice seed wheels
may be ordered:
as wheels only: (“D” p/n, without Flow Gate), or
as kits (“A” p/n, with Flow Gate).
7. The tables on pages 29-43 or 61-75 are insufficient
for setting the seed monitor to control the ground
drive. The monitor also needs a figure for meter
throughput. Running a calibration (page 26) is the
easiest way to ensure that your material is accurately
applied.

Fertilizer Rate
The YP30/40 Planter planter optionally includes one or
two fertilizer manifolds:
Type 2 - single section, single inlet, and/or
Type 3 - three section, three inlet
and may include one ground-driven pump for the Type 2
manifold.
The Type 2 manifold may be supplied by tanks on the
planter, or tanks off the planter, typically a semi-mounted
trailing tank cart or the 400 gallon tank on a trailing
PFC2000 tank cart.
The Type 3 manifold is designed to use an off-planter
pump and tank, typically the PFC1600 or PFC2000 tank
cart.
Fertilizer rate is independent of seed rate. Fertilizer rates
are set by the pump system(s). On-planter ground drive
pump operations are described on page 49 and in the
YP30/40 Planter Operator Manual. Off-planter pump
operations are described in the tank manual.
Manifold systems include orifice plates at each row unit
drop line. Each fertilizer system normally includes a
pressure relief valve and strainer. These components
affect consistency of flow across all rows.
Note: Great Plains recommends checking with your local
Agronomist as soil conditions vary. Soil conditions
in your area may need lesser or more amounts of
fertilizer than represented in these charts. Do not
exceed 12 gallons/ac (112 liters/Ha) in any case.

Orifice Plate Size20283448598098
Orifice Plate Selection
Refer to Figure 12
Orifice plates at each drop line nozzle provide
back-pressure that balances flow in the manifolds,
assuring that each row obtains the same flow rate. For a
given rate, there may be more than one orifice size that
provides the recommended back-pressure.
Plates are provided with the system(s) in three sizes.
Additional sizes are available.
In general, the orifice needs to be small enough to
create a minimum pressure in the manifold but large
enough to prevent the manifold pressure from exceeding
the maximum:
15psi min., 15-40 optimal, 65 psi max.
Using an orifice size too large can result in unequal flow
at rows. Using a size too small can cause excess
back-pressure resulting in material dumping at the relief
valve.
Determine Orifice Size
The chart below. shows rate ranges for each Great
Plains orifice size and row spacing. You may need to
change to the next higher or lower orifice for a different
fertilizer solution density and/or a different ground speed.
To reduce orifice plugging and pump wear, use the
largest orifice practical for your fertilizer application rate.

Agricultural Chemical Hazard:
Wear protective gloves when changing orifice plates. Consult
material manufacturer or supplier documents for proper
handling and steps to take if skin contact occurs.
Material Loss/Equipment Damage Risk:
Set application rate at pump using pump drive chart., not by
orifice size. Orifice size is only used to create 15-65 PSI back
pressure to provide even flow between rows. An orifice size too
small causes material loss at relief valve. A size too large can
cause application imbalance across the planter.

Install Orifice Plates
Refer to Figure 13
Insert the plate inside the gasket supplied with the
nozzle. Insert the gasketed plate with the legend side
facing out the nozzle outlet (typically up).
In general, the orifice needs to be small enough to
create enough pressure in the manifold to operate the
check valvesin the boom clamps, but not so much that
the system dumps product at the boom relief valve.
The recommend operating pressure is: 15 to 40 psi
Using an orifice size too large can result in unequal flow
at rows, intermittent flow, and flow stoppage at rows
where pressure falls below the 8 psi required to open the
clamp check valve. Using a size too small can cause
excess back-pressure resulting in material dumping at
the boom relief valve.
Use the same size at all active rows.

Row Shutoff
Refer to Figure 13
Unused drop lines may be shut off by replacing the
nozzle with a Great Plains 832-042C cap. Twin row
boom systems separately include caps for half the rows.
When installing a cap:
• It is not necessary to remove the gasketed orifice plate
• Use a tie wrap or other line to secure the loose nozzle
• Adjust pump and/or orifice plates for new rate and row
Mis-Application or Material Loss Risk:
Do not apply materials after row shut-off or row turn-on
without first reviewing setup. Merely changing the number of
active rows does not change the application rate. If pump and/
or orifice size changes are not also made, pressures could be
too low or too high.

Gaskets may also be ordered separately as Great
Plains part number CP18999-EPR.
Agricultural Chemical Hazard:
Wear protective gloves when changing orifice plates and
strainer screens. Consult material manufacturer or supplier
documents for proper handling and steps to take if skin contact
occurs.

Strainer
Refer to Figure 14
A Banjo brand strainer is supplied with the ground drive
fertilizer pump. It is plumbed before the Hypro pump. The
standard 80 mesh screen should be suitable for most
applications. Other screen sizes are available from Banjo
Corporation.
Wear protective gloves when changing screens.
If changing screen sizes, keep in mind the following.
• A smaller mesh (100) will keep 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 resulting in a reduced application rate.
A relief valve is plumbed after the pump outlet to protect
the manifold and pump from excessive pressure. Any
product that dumps over the relief valve will discharge
from the dump line.
To set relief valve:
Refer to Figure 15
1. Unlock plastic jam nut from relief valve knob.
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. Watch for relief valve
discharge while operating in the field.
5. If valve is dumping product and gauge reads under
65 psi, stop tractor and turn knob clockwise (looking
down)1⁄4 turn. Continue operating at normal field
speed. Repeat this step as needed until no product
is discharged from relief valve.
6. If pressure gauge reads above 65 psi, change to a
larger orifice. Go to step 2. Repeat steps.

Ground Drive Fertilizer Rate
One JohnBlue ground drive pump customarily
supplies a Type 2 boom on the planter.
Equipment Damage Risk:
Contact wheel and chain system operate whenever the planter
is lowered and in motion. If planting without fertilizing, the
pump must not be allowed to run dry. Disconnect chain or
remove sprocket.
Refer to Figure 16 and Figure 17
Coarse rate is set by a single “driving” sprocketon the
ground drive assembly. Fine rate is set on a dial (setting
3
hub)at the pump, using a tool supplied with the pump.
Rate settings may be established in any of three ways:
• the table on the next page,
• the slide chart provided with the pump, or;
• a calculator on the JohnBlue internet web site
(www.cds-johnblue.com)
1. Check plumbing setup. See “Setting Relief Valve”
and “Strainer” in the Operator Manual.
2. Determine Driving sprocket (15T or 47T) required
from table, slide chart or web calculator. If this
sprocket is already installed on driven shaft, skip to
step 7. Otherwise, to change sprocket, continue with
step 3.
3. Remove knob and guard. Loosen idler, and
remove chain from lower jackshaft.
4. Select the new sprocket from the storage shaft.
Remove the pins, and exchange sprockets. Store the
previous sprocket on the storage shaft.
5. Remount the chain. Re-engage idler, tightening
so that the longest span of the chain has1⁄4in (6mm)
of slack.
6. Remount guard and secure with knob.

821-069C bucket, 5 gallon (19 liter)
Ezee Glide Plus Lubricant
To maximize performance of Great Plains metering
systems, it is imperative to use only “Ezee Glide Plus”
lubricant.“Ezee Glide Plus” Talc-Graphite lubricant is
mandatory for all seeds, especially treated or inoculated
seed. Thorough mixing of seed and added lubricant
is required.
Recommended usage:
For clean seeds other than milo and cotton sprinkle
one cup of Ezee Glide Plus Talc per 4 bushels or units
(170 ml per 100 liters) of seed.
For milo and cotton double the application to
one cup (or more) per 2 bu or units (335 ml per 100
liters) of seed.
Adjust this rate as necessary so all seeds become coated while
avoiding an accumulation of lubricant 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.
Use only approved Graphite Powder available from Great
Plains Mfg. Inc. or Precision Planting to ensure proper
lubrication of finger pickup corn seed meters.
Recommended usage:
For finger pickup meters, add one tablespoon (15 ml) of
graphite for each unit of seed corn (80,000 kernels).
In high humidity conditions, or seeds with heavy seed
treatments, increase the application to two tbsp (30ml).
If delivery of seed from the hopper to the finger meter is
an issue, add “Ezee Glide Plus” talc and graphite blend
at a rate of one cup (237ml) per 4 units of seed. Adjust
until issue is resolved.
Irritation and Chronic Exposure Hazard:
Wear gloves. DO NOT use hands or any part of your body to
mix seed lubricant. Wear a respirator when transferring and
mixing. Avoid breathing lubricant dust. Not an acute hazard.
May cause mechanical eye or skin irritation in high
concentrations. As with all mineral spills, minimize dusting
during clean-up. Prolonged inhalation may cause lung injury.
Product can become slippery when wet.

Sprocket Indexing Charts (Metric)
1. For: your 6- or 12-finger meter, and your twin row
spacing (70cm on this page) find your seed rate in
the Population column, or your seed spacing in the
Seed Spacing column. Seed spacing is
seed-to-seed within a single row of a twin row pair.
2. At the front/forward row unit of a pair, set the driven
(final) sprocket of the meter drive so that tooth
stamped #1 is straight up (TDC, 12:00 position).
3. At the rear/trailing row unit of the pair, set the driven
sprocket so that the tooth number at “Rear Meter” is
in the straight up 12:00 position.
These charts are for 70cm metric spacing. See page 20
for U.S. customary units.
Not Rate or Spacing Charts:
These are NOT seed rate or seed spacing charts. These are for
staggering seed spacing between the rows of a twin row.
Note: For adjusting spacing between rows of the pair,
see “Indexing Fine Adjustment” on page 22.
Setting Error Risk:
Verify the 12:00 sprocket tooth position with the top length of
chain taut.
