Adjust Hitch Height
Although the specified hitch option (clevis or pintle) is
factory-installed, it may not be at ideal tractor height. If a clevis hitch was specified, it needs to be assembled
on the tractor drawbar.
Hitch Heights
The drill operates more effectively if the tongue is level in
field position.
The drill needs to be lowered (in field position) for the fol-
lowing measurements and any adjustments.
23. If the intended tractor is available, and has an adjust-
able or invertible drawbar, set the drawbar to the
operator’s preferred height. If the tractor is not avail-
able, obtain a measurement of the height:
• clevis hitch: to the bottom surface of the drawbar
• pintle hitch: to the top surface of the lower claw
24. Use the parking jack to adjust the tongue until it is
level from front to back. If the work surface itself is
level, use a carpenter’s level on top of the tongue
tube. When level, the top of the tube is approximately
26
3 ⁄
4
in (68cm) above ground at the hitch.
Refer to Figure 66
25. Measure from ground to:
• clevis hitch: to the top surface of lower lug
• pintle hitch: to the bottom of ring
