Hitch Height Adjustment
For proper operation, the drill tongue must run
parallel to the ground in field position. Follow
these instructions to adjust the drill hitch to match
your tractor drawbar height.
Refer to Figure 1
1. Check the distance from the bottom of the
tongue to the ground as shown. Using the drill
jack, adjust the tongue up or down until the
distance is about 45 inches.
2. Back the tractor drawbar up to the drill hitch.
Determine how much adjustment is needed
for the drill to match drawbar height.
Refer to Figure 2
3. Unbolt the hitch from the tongue. Rebolt the
hitch so the drill matches drawbar height.
When hitching the drill to a different tractor, check for
differences in drawbar heights and re-adjust the drill
hitch accordingly.
