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 settings for main seed box.
Refer to Figure 54
To set Small Seeds rate, loosen the wing nut
at each
handle, and adjust the lever position. Tighten nut.
Set the initial rate based on the chart in the Seed Rate
Manual.
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 recom-
mends 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.
1. 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).
2. Note the initial reading on the acremeter, unless you
do not plan to rely on it for the calibration.
3. Check that your gauge-wheel tires are 9.5Lx15 6-ply
Rib Implement and properly inflated. See “Tire Infla-
tion Chart” on page 104.
4. Record the weight of one to three empty containers
collectively large enough to hold seed metered for
6% of one acre.
5. 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.
6. Turn gauge wheel several times to fill seed cups.
Turn until seed drops to ground from each hose.
7. Place empty container(s) under the three hoses to
gather metered seed.
8. Turn gauge wheel until one acre is tallied on acreme-
ter (203 wheel rotations). While turning, check that
cups have ample seed coming into them.

Crushing Hazard:
You may be severely injured or killed by being crushed from a
falling implement or openers. Always have transport locks in
place and frame sufficiently blocked up when working on the
drill.
