ty precautions that should be followed by
the operator to avoid accidents. When you
see this symbol, carefully read the message

in serious bodily injury.
In addition to the design and configuration of equipment, hazard control and accident prevention are depen-
dent upon the awareness, concern, prudence and proper training of personnel in the operation, transport,
maintenance and storage of equipment. Lack of attention to safety can result in accident, personal injury,
reduction of efficiency and worst of all—loss of life. Watch for safety hazards and correct deficiencies prompt-
ly. Use the following safety precautions as a general guide to safe operations when using this machine.
Additional safety precautions are used throughout this manual for specific operating and maintenance proce-
dures. Read this manual and review the safety precautions often until you know the limitations.
1. Read the Operator’s Manual. Failure to read the Operator’s Manual is considered a misuse of this
equipment.
2. Become familiar with all the machine’s controls and all the caution, warning and danger decals
affixed to the machine before attempting to start or operate.

SECTION I
OPERATION
WARNING
NOTE: Hitch pins can be mounted extending
toward the outside or center of the implement to
fit different tractor lift arms. Secure the lift arms
to the pins. (Figure 1)
DURING BLADE ADJUSTMENT
KEEP BODY, HANDS AND FEET CLEAR
OF BLADE.
ATTACHMENT
Attach the center link to the top of the mast and
adjust so that the blade frame will be level in the
operating position.
The box blade should be placed on level ground.
Place the tractor rockshaft control in “position con-
trol” (non-floating) for attaching and detaching the
rear mounted blade. “Draft control” or “position con-
trol” can be used while operating.
DETACHING FROM TRACTOR
Lower the blade to the ground with rockshaft control
in position control. Remove top link from mast, dis-
connect hitch arms from bottom pins and pull tractor
away from blade.
Back the tractor until the ends of the lift arms can be
attached to the lift pins on the implement.

OPERATION
Level the box blade from side to side and front to
rear using adjustments on the tractor’s 3-point lift.
SECTION II - MAINTENANCE
To adjust the scarifier shanks, first remove the pins
which hold the shanks in place. Slide the shanks up
or down to desired position and replace the pins.
(Figure 3)
Keep all blade nuts and bolts tightened to 175 ft. lbs.
Blades can be reversed to use opposite cutting edge
when needed. (Figure 2)
The scarifiers should be adjusted to the lowest posi-
tion to penetrate and break up the surface when
moving large volumes of soil. When leveling, the tips
should be positioned to barely chip the surface, and
when smoothing, the tips should completely clear
the ground.
CAUTION
LOWER THE BLADE AS MUCH AS POS-
SIBLE AND SECURELY SUPPORT
BEFORE MAKING ANY ADJUSTMENT.
Care should be exercised during use of the box
blade to prevent hanging the scarifier points or the
blades on immovable objects or otherwise use the
implement under conditions beyond its designed
capacity.
Inspect your box scraper periodically and replace
any worn or broken parts in order to have it ready
for use when needed.
Worn scarifier tips may be replaced by grinding
or torching off the old tips and welding on
replacements. (Figure 3)
CAUTION
WHEN EQUIPMENT IS TRANSPORTED, USE
NECESSARY DEVICES REQUIRED BY LOCAL
REGULATIONS FOR ADEQUATE WARNING
TO OPERATORS OF OTHER VEHICLES.
Store the box blade out of the weather when it is not
in use. This helps prevent rusting of the blades and
other components.
