This manual (195-325B) replaces the following
discontinued Rate manuals:
Accurately obtaining the desired seed population from
the main seed boxes requires four steps:
1. Setting Drive Type sprockets
(page 3, based on chart)
2. Setting initial Seed Rate Handles
(page 4, initially based on chart)
3. Positioning Seed Cup Doors
(page 4, based on seed type)
4. Calibration: checking actual seeding rate
(page 5)
Seed rate charts, and rate setting/calibrating information,
is included in both the Operator Manual, and this
separate Seed Rate Manual. The Seed Rate manual is
normally stored in a weatherproof holder on the drill, for
field reference. The charts list proper sprocket pairings
and rate-handle settings for various materials and rates.
The seed-rate charts are based on cleaned, untreated
seed of average size and test weight. The charts are
based on factory-supplied tires, inflated to factory
specification. Predicted rates may vary slightly with rib
implement tires, optional on some models.
Many factors will affect seeding rates including foreign
material, seed treatment, seed size, seed weight, field
conditions, tire condition, tire pressure and test weight.
Minor adjustments are commonly required. Set and
check the seeding rate using the procedures following,
then re-adjust the rate as necessary.

Setting Drive Type
Refer to Figure 1
Drive Type is determined by the size (tooth count) of a
sprocket on the seed jackshaft of each drill section. If
changed, the sprocket must be set identically on each
drill section (3 locations).
For correct Drive Type, refer to seed-rate charts
beginning on page 8. The charts list Drive Types as 1, 2,
3 or 4. Each Drive Type corresponds to a specific sized
sprocket, per the table at right, and Figure 2 below.

Changing Drive Type
1. Loosen top idler and slide idler well forward,
particularly if changing to Drive Type 1.
2. Lift drive chain off sprocket currently in use.
3. Remove lynch pin and rearrange sprockets on
jackshaft. Sprocket corresponding to the required
Drive Type is second innermost. Make sure all four
sprockets are accounted for when remounting them
on the shaft.
4. Remount drive chain on the second innermost (Drive
Type) sprocket.
5. Re-engage top idler and secure. Allow1⁄2inch
(13 mm) slack in longest (top) span of chain.
6. Set the same Drive Type on all three drill sections.

Main Box Seed Rate Handle
There are main box seed rate handles for each section of
the drill (2 or 3 handles total). Generally, all need to be
set identically, and you need to calibrate only one
section.
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 seed flow to a drill section
by setting a handle to zero.
To set a handle:
1. Loosen wing nut under handle.
2. Set indicator to just past value from Seed Rate
Chart.
3. Tighten wing nut.

Position Seed Cup Doors
Refer to Figure 4,
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:
(top detent) is for the smallest seeds.
1
Use it for wheat and similar small seeds.
(middle detent) is for larger seeds.
2
Use it for soybeans and similar larger seeds.
(bottom detent) is for oversize or fragile seeds.

If you experience excessive cracking with
setting, use setting.
Note: Handle positionis used for clean-out, not

planting. If set to this position with seed loaded, it
may be difficult to reset it to a normal operating
position.
3
Main Seed Row Shutoff
If alternate row spacings are desired, the unused rows
can be shut off with optional plugs.
1. Clean-out seed. The seed box must be empty prior
to inserting plugs. See “Main Box Clean-Out”inthe
Operator manual.
Refer to Figure 5
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.

Main 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.
Perform the calibration with the drill raised for transport,
but with the opener frames lowered (if the openers are
raised, the clutches will disengage). Leave the tractor
hitched for movement control. Block the tires not being
used in the calibration.
If you have previously calibrated your acremeter (see
Operator’s manual), you can use it to tally acres.
1. Jack up the left drive gauge wheel assembly until the
left section is roughly level. Use blocks to ensure that
the section cannot fall if the jack relaxes, tips over or
fails.
2. Rotate the gauge wheels and check that the drives
and seed cups are engaged, working properly and
free from foreign material. If not already done, set
the Drive Type, Seed Rate Handle and Seed Cup
Doors across the drill. If fertilizer is loaded, remove
the fertilizer drive chain (unless you are
simultaneously calibrating fertilizer rate).
3. Not the previous reading on the acremeter, unless
you do not plan to rely on it for the calibration.
4. Check that your tires match factory specification and
are properly inflated. See the “Tire Inflation Chart”
in the Operator manual.
5. Record the weight of one to three empty containers
collectively large enough to hold seed metered for
6% of one acre.
6. Place several pounds of seed over three seed cups
on the outside end of the left drill box. Pull lower end
seed hoses off of these drops at the opener end.
7. Turn gauge wheel several times to fill seed cups.
Turn until seed drops to ground from each hose.
8. Place empty container(s) under the three hoses to
gather metered seed.
9. Turn gauge wheel until one acre is tallied on
acremeter (see table at right). While turning, check
that cups have ample seed coming into them.
Crushing Hazard:
Always have transport locks in place and frame sufficiently
blocked up when working on the drill. You may be severely
injured or killed by being crushed from a falling implement or
openers.
For example:
on a drill with a row spacing of:
7.5 inches
and row count of:
63
you desire to plant barley at:
49 pounds per acre
which, from the chart, is an initial Seed Rate Handle
scale setting of:
40
For example:
three empty 1.8 pound containers weigh:
5.4 lbs

Note: You may want to repeat calibration procedure 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).
13. Set the center and right drill sections to match the
now-calibrated left section.
14. With calibration complete, Reinstall fertilizer chain (if
removed), reconnect seed hoses, and lower gauge
wheel to ground.
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.

Reading a Seed Rate Chart
Charts in U.S. customary units begin on page 8.
Metric charts begin on page 25.
1. Find your seed. Charts are in alphabetical order by
seed name. Charts covering more than one seed
may be out of order.
For Rape, see Alfalfa.
For Sudan, see Flax.
This example presumes we desire to plant Barley at
48 pounds per acre with a 7.5 inch drill.
There are multiple charts 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.
2530354045505560657075
In our example, that would be Barley chart 2 of 3.
If your seed is not listed, find one with similar size,
shape and density. Density of the test seed used to
65707580859095 100
develop the chart appears under the right end of the
handle scale values.

2. Note the Drive Type in the upper left corner of the
chart for your seed. This number (1-4) is used to
determine the seed jackshaft sprocket. See page 3.
In our example, this is Drive Type 2 (34T sprocket).
3. Find your row spacing in the far left column.
4. Locate your desired seed rate in the table row for
your row spacing.
In our example, 49 is the closest to 48.
5. 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 our example, we will start with a handle setting
of 40, and calibrate. When a target rate falls halfway
between handle settings, you can adjust the handle
slightly to compensate, but calibration is apt to result
in further adjustment anyway.

Setting Fertilizer Rate
The 3S-4000HDF fertilizer meters are driven from the
clutch shaft through a series of sprockets. This system is
independent of the seed meter drive, and is unaffected
by Drive Type. Fertilizer rate is adjusted by changing
1 to 3 sprockets on each drill section (3 sets total).
Fertilizer application rates vary with fertilizer type,
density and particle size. Relative humidity and field
conditions can also affect application rates. The chart on
page 19 is based on fertilizer with average particle size
and a density of 65 pounds per cubic foot. Initially set
rate according to charts, then calibrate the drill to your
material as described on this page.
Perform setup and calibration for the left drill box. Once
determined, set the center and right boxes to match.
Accurately obtaining your application rate requires four
steps:
1. Adjusting target rate for large differences between
material and chart density.
The fertilizer chart is based on fertilizer with a density of
65 pounds per cubic foot (1.04 kg/liter). If your fertilizer
density is within a few percent of that, skip this step and
rely on calibration to determine final Driver/Driven setup.
For larger variances, particularly with very low densities,
pre-compensating can simplify calibration, by choosing a
different target chart value for the application rate.

1. Find your actual material density. Normally, this
reported on the container in which it was supplied. If
not, weigh a known volume and calculate it.
2. Find your material Density in the table at right, and
the Conversion Factor below it.
3. Adjust your target application rate prior to consulting

Fertilizer Rate Calibration
Differences will exist between the tested fertilizer and
field conditions used to generate the Rate Chart, and
your fertilizer and conditions. To accurately achieve your
target application, Great Plains recommends calibrating.
Perform the calibration with the drill raised for transport,
but with the opener frames lowered (if the openers are
raised, the clutches will disengage). Leave the tractor
hitched for movement control. Block the tires not being
used in the calibration.
If you have previously calibrated your acremeter (see
Operator’s manual), you can use it to tally acres.
1. Jack up the left drive gauge wheel assembly until the
left section is roughly level. Use blocks to ensure that
the section cannot fall if the jack relaxes, tips over or
fails.
2. Rotate the gauge wheels and check that the drives
and seed cups are engaged, working properly and
free from foreign material. If not already done, set
the Range and Final Drive for the left section. If seed
is loaded, remove a seed drive chain or set the Seed
Rate Handle to 0 (unless you are simultaneously
calibrating seed and fertilizer rates).
3. Note the reading on the acremeter, unless you do
not plan to rely on it for the calibration.
4. Check that your gauge-wheel tires are of factoryspecified size and properly inflated. See the “TireInflation Chart” in the Operator manual.
Crushing Hazard:
Always have transport locks in place and frame sufficiently
blocked up when working on the drill. You may be severely
injured or killed by being crushed from a falling implement or
openers.
For example:
you desire to apply 65 lb/cu-ft material at a rate of:
78 pounds per acre
on a 7.5 inch row spacing drill with a row count of:
63
Per the table, the drive system setup is:

5. Record the weight of one to three empty containers
collectively large enough to hold fertilizer metered for
6% of one acre.
6. Place several pounds of fertilizer over three fertilizer
openings the outside end of the left drill box. Pull
lower end fertilizer hoses off of these drops at the
opener end.
7. Turn gauge wheel several times to fill flute cups. Turn
until fertilizer drops to ground from each hose.
8. Place empty container(s) under the three hoses to
gather metered fertilizer.
9. Turn gauge wheel until one acre is tallied on
acremeter (see table at right). While turning, check
that cups have ample fertilizer coming into them.
10. Weigh metered fertilizer. Subtract initial weight of
container(s).

14. Consult the chart for the chart rate used for your first
calibration run with this material. If the just-measured
result was low, add the [adjusted] variance to the
previously used chart rate. If the measured result
was high, subtract the [adjusted] variance from the
previous chart rate.
15. Reset the fertilizer Range and Final Drive based on
the settings at the new chart rate.
16. You may want to repeat calibration procedure if your
results varied greatly from the desired target rate.
17. With calibration complete, Reinstall seed chain (if
removed) or reset Seed Rate Handle, reconnect
hoses, and lower gauge wheel to ground.
18. Set the center and right drill sections to match the
now-calibrated left section.
When drilling, check metering rate by noting acres
drilled, amount of fertilizer added to drill and level of
material in drill box. If you are applying more or less
fertilizer than desired, adjust metering rate slightly to
compensate for field conditions.
For example:
Our measured rate was high, so we
subtract the variance (19)
from the chart rate (78)
to obtain a new chart rate (59).
This is halfway between two chart rows (56 and 62)

Seeding rate from the optional Small Seeds Attachment
is controlled entirely by seed rate handles on each small
seeds box. No sprocket changes are required, and small
seeds rate is unaffected by Drive Type or other settings
for the main seed box.

Small Seeds Rate Calibration
Differences will exist between the tested seed and field
conditions used to generate the Small Seeds Rate
Charts, and your seed and conditions. To accurately
achieve your target population, Great Plains
recommends calibrating.
Perform the calibration with the drill raised for transport,
but with the opener frames lowered (if the openers are
raised, the clutches will disengage). Leave the tractor
hitched for movement control. Block the tires not being
used in the calibration.
If you have previously calibrated your acremeter (see
Operator’s manual), you can use it to tally acres.
1. Jack up the left drive gauge wheel assembly until the
left section is roughly level. Use blocks to ensure that
the section cannot fall if the jack relaxes, tips over or
fails.
2. Rotate the gauge wheels and check that the drives
and seed cups are engaged, working properly and
free from foreign material. If not already done, set
the Small Seeds Rate Handle. If fertilizer is loaded,
remove the fertilizer drive chain (unless you are
simultaneously calibrating fertilizer rate).
3. Note the reading on the acremeter, unless you do
not plan to rely on it for the calibration.
4. Check that your gauge-wheel tires are the factoryspecified size and properly inflated. See the “TireInflation Chart” in the Operator manual.
5. Record the weight of one to three empty containers
collectively large enough to hold seed metered for
6% of one acre.
6. Place several pounds of seed over three seed cups
on the outside end of the left drill box. Pull lower end
seed hoses off of these drops at the opener end.
7. Turn gauge wheel several times to fill seed cups.
Turn until seed drops to ground from each hose.
8. Place empty container(s) under the three hoses to
gather metered seed.

Small Seeds Row Shut-Off
If alternate row spacing is required for small seeds,
optional plugs are available to block flow inside the seed
box tray.
1. Clean-out seed. The seed box must be empty prior
to inserting plugs. See “Small Seeds BoxClean-Out” in the Operator manual.
2. Before installing plugs, inspect the seed boxes for
existing factory-installed plugs. These are blocking
extra unused seed ports. You may want to identify
these plugs with an indelible marker.
3. 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.
4. Review seed rate settings prior to planting. Perform
