Lower 3-Point Hitch Offset
Refer to Figure 3-1:
WARNING
!
To avoid serious injury or death:
After offsetting, check to see that the driveline clears all
shields on the tiller, tractor, and tiller hitch. If not, decrease
offset until clearance is obtained.
The tiller can be shifted a maximum offset of 7" left or
right of the gearbox input shaft by moving the hitch
clevises (#1) 7" to the right or left.
For best tillage results, adjust tiller offset to the right by
moving the hitch clevis to the left far enough to cover the
tractor’s right rear wheel tread marks.
1.
Loosen hex nuts (#2) until clevises (#1) can be
moved on the front tube.
2. Slide lower hitch clevises (#1) an equal amount left or
right up to 7" while holding the 26 7/8" distance
between clevises.
3. Retighten hex nuts (#2) to the correct torque value.
