Calibration Overview
Detailed calibration steps vary with each box, see:
“Main/Dual Box Seed Rate Calibration” on page 6,
“Fertilizer Rate Calibration” on page 31,
“Native Grass Rate Calibration” on page 17, and
“Small Seeds Rate Calibration” on page 24,
Some general information applies to all boxes, and is not
repeated in those pages referenced above.
Calibrate with Drill Raised
Perform the calibration with the drill hitched and raised.
Install lift-assist cylinder lock(s). Calibration with the drill
lowered is not recommended, as the drive tires in ground
contact prevent drive operation.

Calibration Crank Storage
Refer to Figure 2
The calibration crank is found at the top front frame,
left of center, pinned to a stob on a 3-point weldment.
Note: The retaining pin at the stob can also secure the
crank to the jackshaft.

Using Calibration Crank
Place the hex socket of the crank on the right end of the
main jackshaft .
Operate the crank clockwise
A wide range of cranking speeds produce accurate
calibrations. For reference, at 6 mph (10 kph) field speed,
jackshaft rpm is 65 (about 1 revolution per second).

Main and Dual Box Seed Rate
Accurately obtaining the desired seed population
requires four steps:
1. Setting Drive Type gearbox (from chart)
2. Setting initial Seed Rate Handle (from chart)
3. Positioning Seed Cup Door (by seed type)
4. Calibration: checking predicted seeding rate
Seed rate charts begin on page 8. The charts list proper
Drive Type and seed rate handle settings for various
seeds and seeding rates.
The seed rate charts are based on cleaned, untreated
seed of average size and test weight. The charts are
based on factory-supplied 5.70-8 8-Ply tires inflated to
factory specification. Many factors affect seeding rates
including foreign material, seed treatment, seed size,
seed weight, field conditions, tire pressure and test
weight.
Use the charts only as a starting point. Minor
adjustments are commonly required. Set and check the
seeding rate using the procedures beginning on page 6,
then readjust the rate as necessary.
32342
Setting Drive Type
Refer to Figure 3
The charts list Drive Types as 1, 2, 3 or 4. Drive Type is
determined by the handle on the gearbox cover, at left
front of drill.
Move the handle until the Drive Type number appears in
the handle window .
For correct Drive Type, refer to the charts in the Seed
Rate manual. Each Drive Type corresponds to a specific
gear ratio.
Drive Type Relative Speed

Main and Dual Box Seed Rate Handle
Refer to Figure 4
There is a single rate handle for the entire box. There are
separate handles for the standard main seed box and the
optional dual seed box.
The seed rate handle controls the percent engagement
of the seed sprocket in each seed cup. The initial setting
of the handle is given by the Seed Rate Chart.
Note: You can temporarily stop main seed flow (such as
for adjusting level/depth) with handle set to zero.
To set the handle:
1. Loosen wing nut under handle.
2. Move indicator from current setting to about 10
higher than the new desired value from calibration or
the Seed Rate Chart, then back to the desired value.
3. Tighten wing nut.

Position Seed Cup Doors
Refer to Figure 5,
which depicts the seed cup door handle in position .
At each main seed box seed tube, adjust the seed cup
door handle for the seed size.
The handle has three normal operating position detents:
1
(top detent) is for the smallest seeds.
Use it for wheat and similar small seeds.
2
(middle detent) is for larger seeds.
Use it for soybeans and similar larger seeds.
3
(bottom detent) is for oversize or fragile seeds.
If you experience excessive cracking with
setting , use setting .
Note: Handle position is used for clean-out, not

1. Clean-out seed. The seed box must be empty prior
to inserting plugs. See “Main Box Clean-Out” in
Operator manual.
Refer to Figure 6
2. Insert one plug at each row to shut off. Verify the
seed hose path before inserting the plug, as some
hoses do not make a strictly vertical drop to their row
units.
3. Review seed rate settings prior to planting. Perform
calibration calculations with the actual active row
count.

Reading a Seed Rate Chart
1. Find your seed. Charts are in alphabetical order by
common North American seed name. Scientific
names are provided. Charts covering more than one
seed may be out of order.
For Sudan, see Flax.
The example presumes Barley at 60 pounds/acre.
There are multiple chart sections for some seeds,
and the rates may overlap. Use the chart where your
desired rate is closest to 50 on the Seed Rate Handle scale.
In the example, this would be Drive Type 2.
If your seed is not listed, find one with similar size,
shape and density. Density of the test seed used to
develop the chart appears under the right end of the
handle scale values.

2. Note the Drive Type for the chart rate row chosen (at
left above rates). This number (1-4) is used to
determine the gearbox handle setting. See page 3.
In the example, this is
Drive Type 2
3. Locate your desired seed rate in the table row for
your row spacing.
In the example the rate closest to 60 is:
64
4. Note the Seed Rate Handle setting required, at the
top of the column at that seed rate. This is the initial
value set on the Seed Rate Handle. See page 4.
In the example, start with a handle setting of:
50 (or interpolate to 48),
and calibrate. When a target rate falls halfway
between handle settings, you can adjust the handle
slightly to compensate, as in the example, but
calibration is apt to result in further adjustment
anyway.

Main/Dual Box Seed Rate Calibration
Differences will exist between the tested seed and field
conditions used to generate the Seed Rate Charts, and
your seed and conditions. To accurately achieve your
target population, Great Plains recommends calibrating.
Due to the large number of crank revolutions per acre
(310 or 569) and per hectare (766 or 1405), a practical
calibration is a simulation of1⁄
th
acre or1⁄
10
th
hectare.

Example: 3 rows are to be used in the sampling.
ExpectedSample is:
1.38 0.46 3×=
The expected sample net weight is 1.2 lb.
2. To perform this calibration, you need a scale that is
accurate at the aggregate sample size, and three (3)
light containers, each capable of holding the
expected SamplePerRow. Record the empty
container weights.
3. Raise the drill so the gauge wheel is out of ground
contact.
4. Remove the calibration crank from its storage stob.
Store the retaining pin on the stob.
5. Place the hex socket of the crank on the end of the
gearbox input jackshaft (see page 2).
6. Pull the seed hoses off the top of three opener seed
tubes, at the top of the openers. Place the hoses into
each sample container.
7. If not already done, set the Drive Type, Seed Rate
Handle and Seed Cup Doors across the drill. If any
optional seed boxes are loaded, disconnect their
drive or set their rate to zero (unless you are
simultaneously calibrating multiple boxes).
8. Load seed above the rows to be sampled. Load well
more than the expected sample size.
9. Rotate the crank or tire several turns to ensure that
the drives and seed cups are engaged, working
properly, free from foreign material, and that seed is
flowing steadily from the meters. Stop.
10. Note the current reading of the acremeter, unless
you do not plan to rely on it for the calibration.
11. Empty the sample containers back into the seed box,
and place them back under the three hoses to gather
metered seed.
Example: 3 containers, each weighing 0.5lb:
ContainerWeight = 1.5 lb
Crushing Hazard:
Install lift cylinder lock(s) on a raised drill.
Note: You can also rotate the tire, the gauge wheel
jackshaft or the gear box jackshaft. If using a
non-standard rotating/cranking point, rely on the
acremeter to determine the area simulated.
Example: you desire to plant barley at:
60 pounds per acre
which is between
45 and 50
on the Drive Type 2 chart.
Use an initial Seed Rate Handle (InitialHandle) scale
setting of:
48
151-143B Table of Contents Main Box Rates 2011-10-21
Great Plains Manufacturing, Inc. Table of Contents Main Box Rates Main and Dual Box Seed Rate 7
12. Turn crank at a steady rate for the number of turns
specified on page 2, or until one tenth acre or
hectare is tallied on acremeter. While turning, check
that cups have ample seed coming into them.
13. Weigh metered seed. Subtract initial weight of
container(s).
NetWeight GrossWeight ContainerWeight–=
14. Divide the net seed weight by three. Multiply by
number of openers on your drill, and then by ten, to
determine the total of pounds per acre seeded.

15. The Seed Rate Handle scale is a percentage of
meter opening, and its effect is linear near scale
center. Calculate a new scale setting based on the
test.
Set the Seed Rate Handle to the new scale setting.
16. You may want to repeat calibration procedure at the
new setting if your results varied greatly from the
Seed Rate Chart, or if you must operate near the
ends of the Seed Rate handle scale (0-20 or
90-100).

17. With calibration complete, store calibration crank,
reinstall any removed chains or sprockets and

18. Check that your tire(s) is(are) properly inflated. See
“Tire Inflation Chart” in Operator manual.
When drilling, check seeding rate by noting acres drilled,
amount of seed added to drill and seed level in drill box.
If you are seeding more or less than desired, adjust rate
slightly to compensate for field conditions.
