Section 1: Assembly & Set-up
Shank Assembly (Optional)
Refer to Figure 1-1 on page 6:
When possible, the shanks are shipped assembled to the
Grading Scraper. Some shanks may need installation.
DANGER
!
To prevent 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.
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.
Before installing shanks (#15), attach Grading Scraper to
the tractor’s 3-point hitch or raise front of scraper up and
support it with blocks. See
“3-Point Hook-up”
on page 8.
1.
Remove shanks (#15) from shipping crate and insert
them into the front slots with tips pointing forward.
2. Secure shanks with lock pins (#14) and
hairpin cotters (#11).
NOTE:
See Section 2: Adjustments for shank depth.

WARNING
!
To avoid serious injury or death:
Lightweight tractors with rear attached implements may need

Consult your tractor Operator’s Manual to determine proper
weight requirements and maximum weight limitations.
Torque Requirements
Refer to
“Torque Values Chart”

Hitch Assembly
Refer to Figure 1-1 on page 6:
1.
Remove linchpins (#10) from hitch pins (#4).
2. Position hitch straps (#1 & #2) with large holes (A)

3. Attach middle and rear holes in hitch straps to clevis
plates with 3/4"-10 x 2" GR5 cap screws (#6), lock
washers (#9), and hex nuts (#8) as shown. Do not
tighten hardware at this time.
