Shank Adjustments
DANGER
!
To avoid serious injury or death:
Make adjustments to the Box Scraper after it has been
properly attached to a tractor and secured with solid 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 avoid 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.
Refer to Figure 3-1 & Figure 3-2:
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:
1. Press top of shank spring retainer together with a pair
of pliers and pull retainer up out of the shank tube
slot. Be sure to keep shank notch caught in the top
slot to keep it from falling out while removing the
spring retainer.

that will allow the shank notch to be caught in the top
slot. Catch shank notch in the top slot at this height.
•
Refer to Figure 3-1:
Shanks caught at the 2nd
notch (middle notch) are set 2 3/8" (6 cm) below
the side plate.
•
Refer to Figure 3-2:
Shanks caught at the 3rd
notch (bottom notch) are set out of the ground.
3. Fasten shank in place with spring retainer clip by
inserting clip into the top slot behind the shank until
its snaps into place.
Leveling and Pitch Adjustment
Level and pitch adjustments are the same for all models
of Box Scrapers.
1. Adhere to safety precautions under
“Shank
Adjustments”
on this page. Raise shanks fully up.
2. Locate tractor and scraper on a flat lever surface.
Lower scraper down onto the level surface, place
tractor in park, set park brake, shut tractor engine off
and remove switch key.
3. Place a level on the longer front shank bar.
4. Manually adjust either one or both of the tractor’s
lower 3-Point arms up or down to level the scraper
from left to right.
5. Rotate level 90 degrees and then adjust the tractor’s
top center link until unit is leveled from front to back.
NOTE:
Through extensive research and testing,
Land Pride has designed the optimum cutting angle
into your Box Scraper. If needed, shorten top center
link one-half turn at time to increase blade pitch.
