OPERATION AND MAINTENANCE

Leveling the Hitch
1. When unfolding the Grain Drill the hitch is lowered to
its lowest point to allow the wing fold locks to unhook
and clear. Before starting to plant, the hitch should be
leveled to insure proper opener depth and full opener
travel.
2. Make sure the hitch clevis is adjusted for the proper
tractor drawbar height
(See Figure 4-4.)
3. Use the three reference holes at the front of the hitch
as a guide to level the hitch for planting operations
(See Figure 4-5.) The wear pad (inside the hitch
tube) will be visible from the tractor seat as it slides
by the reference holes. When the pad is visible only
through the middle reference hole the hitch should be
level. If the wear pad is visible through the upper or
lower reference holes then the hitch is either too low
or too high. Do not insert any objects in the reference
holes as the wear pad slides over these holes and
could damage the hitch.
