Hitching Tractor to Discovator
Crushing Hazard:
Do not stand or place any body part between Discovator and
moving tractor. You may be severely injured or killed by
being crushed between the tractor and Discovator. Stop

To prevent soil compaction on rows, set tractor wheels
between rows. For hillsides and steep slopes, set trac-
tor wheels as wide as possible for maximum stability.
