Seeding Rate Adjustment
To calibrate the seeding rate, the seeder and plow
must be hooked to the tractor that will be used in
the field andthe hydraulic drive must be hooked to
the tractor remotes.
1. Find desired seeding rate and ground speed
Adjustments
IMPORTANT: Calibrate the seeding rate with a
full box of seed.
on seeding rate chart, page 17. Determine
how many shaft rpms are needed for your
seeding rate and ground speed.
2. With tractor parked and idling in neutral, ad-
just tractor throttle up to field rpm.
3. Engage hydraulic drive. Count the number of
seed-cup-shaft revolutions per minute by using a tachometer.
4. Stop hydraulic drive. If shaft is turning too
slowly or quickly, loosen black knob and adjust flow control on hydraulic drive. See Figure
9. Move lever down to increase rpms. Move
lever up to reduce rpms.
5. When satisfied with flow-control setting, lock
black knob.
Seed Cup Doors
For rice and other small grains, move seed-cupdoor handles to the highest position. For larger
seeds, lower handles to the second or third position to reduce seed cracking. For seed-cup clean
out, move handles to the fourth, wide-open position. Make sure all handles are in the same
position before seeding.
