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
tractor engine and set parking brake before attaching cables
and hoses.
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.
1. Raise tractor three-point arms (if equipped) clear
up to clear Discovator.
2. For TWO-WHEEL DRIVE and MFWD tractors, pin
drawbar in fixed center position for field and trans-
port. For FOUR-WHEEL DRIVE and TRAC-DRIVE
tractors, leave one hole clearance on each side of
drawbar for field position, hitch damage may occur
if pinned solid. Pin in center position for transport to
maintain maximum steering control.
3. Hitch the tractor to the Discovator using the block
or yoke clevis determined by the tractor drawbar.
Use the correct size pin for clevis or block.
Load Sway Hazard:
Lock drawbar swing to center position to minimize any side-
to-side sway to assure proper tracking in the field, and safe
road travel. See
