DANGER
!
To avoid serious injury or death:
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.

Always keep your body extremities out from under the shanks
and cutting blades while removing, installing, and adjusting

Shank settings are based on the vertical distance
measured from bottom edge of side plates to bottom of
shank tips. Adjust each shank height as follows:

blades are resting on four 6” high support blocks.
a. Locate two of the support blocks close to the front
of the scraper under both side panels.
b. Locate the other two support blocks under the
grader blades and close to the side panels.
3. Place tractor gear selector in park or set park brake,
turn off engine, and remove switch key before
dismounting tractor.

hole and replace bent pin (#2). Secure bent pin with
