Great Plains | 151-144B | 2019/03/14 1
Introduction
This Material Rate Manual assists in the proper
setting of seeding and fertilizer rates for the
3P1006NT drill.
Independent mechanisms drive the main seed,
native grass, dual seed, small seeds, and fertilizer
applications.
The rates in the charts are approximate. To assure
the most accurate seeding, it is recommended that
the drill be calibrated for the desired seed at the time
of planting.
Some setup, operation, and adjustment material in
this manual may be repeated from the drill operator
manual. You need to be thoroughly familiar with drill
operations and adjustments before applying the
information from this manual.
Many factors can affect rates including foreign
material, seed treatment, seed size, seed weight,
field conditions, humidity, tire pressure, and tire
slippage.
Safety Information
The safety symbol indicates a potential safety
hazard to persons operating or near the
machine and advises on how to avoid it.
The notice symbol indicates a potential for
machine or property damage from operator
error and advises on how to avoid misuse.
The information symbol indicates useful - but
not crucial - information for machine
operation, assembly, or adjustment.
Review the safety information in the operator manual
before calibrating or making any adjustments to the
drill.

3P1006NT Table of Contents Calibration Overview
Calibration Overview
Detailed calibration steps vary with each box. Some
general information applies to all boxes, and is
explained here.
Calibration Crank
The calibration crank is stored at either the top front
frame for older drills, or on the inside of the left-hand
3-point hitch for newer drills.
The retaining pin used for storage can also secure
the crank to the jackshaft.
The following table shows what is being calibrated,
serial number range, and where to locate the crank
for calibrating.
A drill with serial number A1067W and above has a
shared jackshaft connecting both gearboxes, but the
revolutions per area are different for the left and
optional right drive systems. ranking operates all
meters across the drill.
A drill with serial number A1066W and below has
independent left and optional right drive systems.
Cranking operates all meters on that side.
General Calibration Procedure
Perform the calibration with the drill hitched and
raised. Install lift-assist cylinder lock. Calibration with
the drill lowered is not recommended, as the drive
tires in contact with the ground prevent drive
operation.
Operate the crank in the tire rotation direction:
left end of drill or shaft - counterclockwise
right end of drill or shaft - clockwise
A wide range of cranking speeds produce accurate
calibrations. For reference, at 10 kph (6 mph) field
speed, jackshaft rpm is 65 (about 1 revolution per
second).
On boxes not being calibrated, empty the boxes, set
rate handles to zero, or remove a drive chain to
prevent undesired meter operation.

Calibration Preparation for S/N A1211W+
These instructions are for preparing to calibrate a
dual seed or native grass option.
1. Unpin the coupler (1) and slide out of the way to
disconnect the two jackshafts.
2. Make sure the 42 pitch chain (2) is installed on
the right-hand gearbox. The chain must be
routed around the 12 tooth sprocket on the
gearbox and around the 22 tooth sprocket on the
left end of the calibration shaft. Tighten the chain
with the idler.
3. Place the calibration crank (3) on the right end of
the calibration shaft (4).
Calibration Crank Revolutions

The table below applies to the main seed, optional
fertilizer, and optional small seeds. The crank

Place the calibration crank on the end of the

Right side cranking for S/N A1067W - A1210W
The following charts apply to the dual seed and
native grass options. The shaft being cranked is on
the output side of the gearbox, so the cranks per
area vary with gearbox drive type.
Crank counts below 10 are not recommended.
Sample sizes may be too low.

Place the crank on either end of a main jackshaft at
the appropriate gearbox. See "Calibration Crank”

If weight brackets are installed, there is not
enough clearance at the left end of the left
side shaft. An electronic acremeter may also
be installed there.

Great Plains | 151-144B | 2019/03/14 5
Main and Dual Seed
To get the desired seed population requires four
steps:
1. selecting one of four drive types
2. setting the seed rate handle
3. positioning the seed cup door
4. checking the seeding rate
The seed rate charts are based on cleaned,
untreated seed of average size and test weight, and
on factory-supplied tires inflated to factory
specification.
The seed rate charts list the proper drive type and
seed rate handle settings for various seeds and
seeding rates.
Use the charts only as a starting point. Minor
adjustments may be required. Set and check the
seeding rate using the procedures beginning on
page 8, then adjust the rate as necessary.
Drive Types
The charts list drive types as 1, 2, 3 or 4. Drive type
is set using the handle (1) on the gearbox cover:
at left front of drill for the main seed box, and
at right front of drill for the dual seed and native
grass options.
Move the handle until the drive type number appears
in the handle window (2).
Each drive type corresponds to a specific gear ratio.
Seed Rate Handle
The seed rate handle controls the percentage of
engagement of the seed sprocket in each feed cup.
The initial setting of the handle is given by the seed
rate chart.
You can temporarily stop the main seed flow
(such as for adjusting level/depth) with the
handle set to zero.
There are separate seed rate handles for the
standard main seed and the dual seed option.
To set the handle:
1. Loosen the wing nut (1) under the handle.
2. Move the indicator (2) from the current setting to
about 10 higher than the new value, then back to
the new value.
3. Tighten the wing nut.

3P1006NT Table of Contents Main and Dual Seed
Seed Cup Door Settings
At each main seed tube, adjust the feed cup door
handle (1) for the seed size.
The handle has the following settings:
(A) Smallest seeds - wheat and similar small seeds.
(B) Soybeans and similar larger seeds.
(C) Oversize or fragile seeds, or if experiencing
cracking with setting B.
(D) Used for clean-out, not planting. If set to this
position with seed loaded, it may be difficult to reset
to a normal operating position.
Row Shutoff
If alternate row spacings are desired, the unused
rows can be shut off with optional feed cup plugs.
To install feed cup plugs:
1. Clean out seed. The seed box must be empty
before inserting the feed cup plugs.
2. Insert one plug at each row to be shut off. Verify
the seed hose path before inserting the plug as
some hoses do not make a vertical drop to their
row units.
3. Review seed rate settings before planting.
Perform calibration calculations with the active
row count.
