You may be severely injured or killed by being crushed
between the tractor and drill. Do not stand or place any part
of your body between drill and moving tractor. Stop tractor
engine and set park brake before installing pins.
1. Hitch drill to a suitable tractor.
2. Set seed population as explained in “Seeding
Rate”, page 26.
3. Load box with clean seed.
4. Raise drill. Rotate gauge wheel. Check that feed
cups, seed tubes and drives are working properly
and free from foreign material by looking for seed
flow under each opener.
5. Record acremeter readout. Subtract initial reading
from later readings to determine acres drilled.
6. Pull forward, lower drill and begin seeding.

row ends and for other short-radius turns. Seeding
will stop automatically as drill is raised.
