Seed, Small Seeds and Fertilizer Rate Charts
for the 1300 and 1300F 13-Foot End Wheel Drill
The following pages are to assist in the proper setting of seeding and
fertilizer rates for the 1300 and 1300F. The rates indicated 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.

Introduction
This manual is your guide to planter adjustments for
achieving specific seed population and fertilizer density
targets.
Although some setup/adjustment material herein is
repeated from the drill Operator Manual, you need to be
thoroughly familiar with drill operations and adjustments
before applying this Seed Rate manual and its table data.

Main Box Seed Rate
Accurately obtaining the desired seed population
requires four steps:
1. Setting Drive Type sprockets (from chart)
2. Setting initial Seed Rate Handle (from chart)
3. Positioning Seed Cup Door (by seed type)
4. Calibration: checking predicted seeding rate
Main box seed rate charts begin on page 8. The charts
list proper sprocket pairings 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 7.5 x 20, 4-ply Rib Implement end wheel 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 following, then
readjust the rate as necessary.

Setting Drive Type
Refer to Figure 1 and Figure 2
Drive Type is determined by the size (tooth count) of a
sprocket on the seed jackshaft .
For correct Drive Type, refer to the 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 below, and Figure 1.

Main Box Seed Rate Handle
There is a single seed rate handle for the entire the drill.
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 the drill (such
as for adjusting level and depth) by setting the
handle to zero.
To set the handle:
Loosen wing nut under handle.
6. Move indicator from current setting to about 10
past the new desired value from calibration or the
Seed Rate Chart, then move it back to the new
desired value.
7. Tighten wing nut.

Position Seed Cup Doors
Refer to Figure 4,

At each main seed box seed tube, adjust the seed cup

The handle has three normal operating position detents:
(top detent) is for the smallest seeds.

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.

inserting plugs. See “Main Box Clean-Out” in Operator
Manual.
8. 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.
9. Review seed rate settings prior to planting. Perform
calibration calculations with the actual active row
count.

Reading a Seed Rate Chart
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.
The example presumes you desire to
plant:
Barley at 60 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.
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
develop the chart appears under the right end of the
handle scale values.
10. 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 the example, this is
Drive Type 2 (34T sprocket).
11. Find your row spacing in the far left column.
12. Locate your desired seed rate in the table row for
your row spacing.
In the example the rate closest to 60 is:
64
13. 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 47),
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 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 opener frames lowered (if
the openers are raised, the clutch disengages). Leave
the tractor hitched for movement control.
Estimate the sample sizes.
Take your planned population (in our example,
barley at 60 pounds per acre
and divide it by the row count of your drill
21 in our example.
The expected sample size is 2.9 pounds per row, or
8.6 pounds for 3 sample rows.
14. To perform this calibration, you need a scale that is
accurate near the aggregate sample size, and three
(3) light-weight containers, each capable of holding a
row’s sample.
15. Disengage the lock-out hub (see Operator Manual),
to permit independent rotation of the main jackshaft.
Refer to Figure 6
16. Remove the calibration crank from its storage stob
on the left top side of the main toolbar. Store the
retaining pin on the stob.
Refer to Figure 7
17. Place the hex socket of the crank on the left end of
the main jackshaft.
18. 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.
19. 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).
20. Load seed above the rows to be sampled. Load well
more than the expected sample size.
21. Rotate the crank several turns counter-clockwise 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.
22. Note the current reading of the acremeter, unless
you do not plan to rely on it for the calibration.
23. Empty the sample containers back into the seed box.
24. Record the weight of the empty containers and place
them back under the three hoses to gather metered
seed.

25. Turn crank at approximately 23 rpm until one acre is
tallied on acremeter. While turning, check that cups
have ample seed coming into them.
Row Spacing Rotations Per Acre (Ha)
6 inch (15.2 cm) 134 (331) rotations
7.5 inch(19.1 cm) 133 (329) rotations
10 inch (25.4 cm) 131 (324) rotations
26. Weigh metered seed. Subtract initial weight of
container(s)
27. Divide the net seed weight by three. Multiply by
number of openers on your drill to determine the
total of pounds-per-acre seeded.
28. 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.
29. 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).
30. With calibration complete, store calibration crank, reengage lock-out hub, reinstall fertilizer chain (if
removed) and reconnect seed hoses.
31. Check that your end-wheel tires are 7.5 x 20, 4-ply
Rib Implement and 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.
