IMPORTANT SAFETY PRECAUTIONS  
This symbol is used to call attention to safe-  
ty precautions that should be followed by  
the operator to avoid accidents. When you  
see this symbol, carefully read the message  
that follows and heed its advice. Failure to  
comply with safety precautions could result  
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.  
3. Before starting or operating the machine, make a walk around inspection and check for obvious  
defects such as loose mounting bolts and damaged components. Correct any deficiency before  
starting.  
4. Do not allow children to operate the implement. Do not allow adults to operate it without proper  
instruction.  
5. Do not carry passengers.  
6. Keep the area of operation clear of all persons, particularly small children and pets. The operator

8. Keep hands and feet away from implement.  
9. Wear personal protective equipment such as, but not limited to, protection for eyes, ears, feet,  
hands and head when operating or repairing the equipment. Do not wear loose clothing or jewelry  
that may catch on equipment moving parts.  
10. When performing adjustments or maintenance on the implement, first lower it to the ground or block  
it securely at a workable height.  
11. Never stand between tractor and implement while tractor is being backed to the hitch.  
12. Reduce speed when transporting implement to avoid bouncing and momentary loss of steering.  
13. Use tractor flashing warning lights, day or night, when transporting implement on road or highways  
unless prohibited by law.

U.S. Public Law 91-596 (The Williams-Steiger Occupational and Health Act of 1970) OSHA

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.
