Tractor Requirements
The Retractable Box Scrapers are designed with a
3-Point category l & II hitch. Horsepower rating of tractor
should not exceed 65 horsepower.
!
WARNING
Ballast weights may be required to maintain steering control.
Refer to your tractor’s operator’s manual to determine proper
ballast requirements.
Torque Requirements
Unless specified, refer to “Torque Values Chart” on
page 16 to determine correct torque values. See
“Additional Torque Values” at the bottom of chart for
exceptions to common torque values.
Hydraulic Cylinder Assembly
Refer to Figure 1-2:
1. With Box Scraper setting on the ground, position
hydraulic cylinder (#1) with hydraulic fittings facing
forward and cylinder base up as shown.
2. Attach cylinder base to the upper lug with cylinder
pin (#2) and hairpins (#3).
3. Attach cylinder rod clevis between the two lower
lugs (#6) with clevis pin (#4) and cotter pin (#5). Bend
one leg of cotter pin to keep it from falling out.
4. Attach hydraulic couplers (supplied by customer) to
hydraulic hoses.
3-Point Hook-up
Refer to Figure 1-3:
!
DANGER
Tractor hook-up to equipment is dangerous and can result in
serious injury or death. Do not allow anyone to stand between
tractor
and Retractable Box Scraper while backing-up to
implement. Do not operate hydraulic 3-Point lift controls
while someone is directly behind tractor or near the scraper.
A 3-Point Category I or II hitch is required. The lower lift
arms of the 3-Point hitch must be stabilized to prevent
side-to-side movement. Most tractors have sway blocks
or adjustable chains for this purpose.
1. Slowly back tractor up to the Box Scraper and use
tractor’s 3-Point hydraulic control to align lower hitch
link holes with clevis lug holes on the Box Scraper.
2. Engage tractor park brake, shut tractor engine off
and remove key before dismounting from tractor.
3. With tractor’s lower lift arms aligned and positioned
in the clevises, attach lower arms to the clevises with
hitch pins and secure with linchpins.
4. Connect top center link to the upper hitch using
customer supplied clevis pin and linchpin.

5. Return to the tractor and slowly operate 3-Point
hydraulic control lever to fully raise and lower
Retractable Box Scraper while checking for
clearances between the scraper and tractor tires,
drawbar etc. Move or remove drawbar if it interferes
with the scraper.
6. Ensure that the lower arms are stabilized to prevent
excessive side movement.
7. See “Level and Pitch Adjustment” on page 11 for
instructions on how to level the scraper.
