Hitch & Shank Assembly
Refer to Figure 1-1:
Make adjustments to the implement after it has been properly
attached to a tractor and secured with solid non-concrete
supports in the up position. Never work around or under
equipment supported by hydraulics. Hydraulics can drop
equipment instantly if controls are actuated or if hydraulic
lines burst even when power to hydraulics is shut off.
WARNING
!
To prevent serious injury or death:
•
Always keep your body extremities out from under the
shanks while adjusting them. It is possible for the shanks to
fall causing injury to your feet and/or legs.
•
Keep clear of the shank slots while adjusting shank height.
Shanks can pinch body parts in the slots during adjustments.
