3-Point Hook-up
Refer to Figure 1-3:
DANGER
!
To avoid serious injury or death:
A crushing hazard exists while hooking-up and unhooking
implement. Keep people and animals away while backing-up
to implement or pulling away from implement. Do not operate
hydraulic controls while a person or animal is directly behind
the power machine or near the implement.
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 while using
the tractor’s 3-point hydraulic control lever to align
lower hitch holes with Cat. I or Cat. II clevis lug holes
on the Box Scraper.
2. Engage tractor park brake, shut tractor engine off
and remove key before dismounting from tractor.
3. Attach lower lift arms to Cat. I or Cat. II clevises with
hitch pins (#1) and secure with linchpins (#2).
4. Connect top center link to the upper clevis lugs using
customer supplied clevis pin (#3) and hitch pin
keeper (#4).
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 12.
NOTE: Land Pride’s Quick Hitch can be attached to
the tractor to provide quick and easy 3-point hook-
up and detachment. See your nearest Land Pride
dealer to purchase a Quick-Hitch.
Hydraulic Hook-up
DANGER
!
To avoid serious injury or death:
Relieve all hydraulic pressure before disconnecting any lines
or pipes between implement and tractor hydraulic system.
WARNING
!
To avoid serious injury or death:
Hydraulic fluid under high pressure can penetrate the skin
and/or eyes causing a serious injury. Wear protective gloves
and safety glasses or goggles when working with hydraulic
systems. Use a piece of cardboard or wood rather than hands
when searching for leaks. A doctor familiar with this type of
injury must treat the injury within a few hours or gangrene
may result. DO NOT DELAY.
Refer to Figure 1-3:
1. Connect hydraulic hoses (#6 & #7) to tractor remote
outlets.
2. Cycle hydraulic system by extending and retracting
hydraulic cylinder several times. It may be necessary
to purge the system of trapped air if operation
remains sluggish. Purge the system as follows:
Refer to Figure 1-2 on page 7:
a. Lower Box Scraper until it is resting on the ground
and shut tractor engine off.
b. Remove cotter pin (#3), flat washer (#2), and
lower cotter pin (#4).
c. Loosen fitting (#7) to allow fluid to escape.
d. Slowly activate tractor control lever to purge any
trapped air from the system.
e. Once the system has been purged, tighten
fitting (#7) and attach cylinder (#6) to lower
lugs (#1) with clevis pin (#4), flat washer (#2), and
cotter pin (#3).
