Small Seeds Rate
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.
Refer to Figure 9
To set Small Seeds rate, loosen the wing nut
at each
handle, and adjust the lever position. Tighten nut.
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 factory-
specified size and 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.

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:
using a row spacing of:
7.5 inches
row count:
63
you desire to plant alfalfa at:
10 pounds per acre;
this corresponds to an initial Seed Rate Handle of:
50
For example:
three 0.5 pound (8 oz.) containers weigh:
1.5 lbs
