This section will help you prepare your tractor and drill for
use. The drill hitch must be adjusted to match drawbar
height, and the drill control console must be installed in
your tractor.
This section also covers bleeding the drill hydraulics and
making drill frame and box adjustments. As the operator,
you may need to perform these functions after dill repair.
Before operating the drill, check that the hydraulic systems
are free or air, the frame is level, and boxes are aligned.

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.
1.
Check the distance from under the tongue to the
ground as shown in Figure 1-1. Using the drill jack, ad-
just the tongue up or down until the distance is about
28 inches
.

Back the tractor drawbar up to the drill hitch. Deter-
mine how much adjustment is needed for the drill to
match drawbar height.
3.
Unbolt the hitch from the tongue. Rebolt the hitch so
the drill matches drawbar height. Depending on the
size of your drill, refer to for the different ways you can
bolt the hitch and the resulting hitch heights.
