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 
dependent 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, person-
al injury, reduction of efficiency and worst of all—loss of life. Watch for safety hazards and correct deficien-
cies promptly. 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 mainte
nance procedures. 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 cutter. 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 

should cease mowing whenever anyone comes within the operating area.

7. Clear the work area of objects which might be picked up and thrown.

8. Wear eye protection and use a piece of cardboard or wood rather than hands to search for hydraulic 

leaks. Escaping hydraulic oil under pressure can penetrate skin. If fluid is injected into the skin, it must 
be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may 
result.

9. Do not operate without all guards and shields in place and in good condition.

10. Stop PTO, lower implement to ground, place tractor transmission in neutral or park, set parking brake, 

stop tractor engine, remove ignition key and wait for all motion to completely stop before leaving the 
tractor.

11. Keep hands and feet away from blades.

12. This cutter is not to be operated along highways or in any area where people may be present unless 

all sides of the unit are enclosed by permanent bands, safety chains or other factory approved safety 
shields that are in good repair.

13. 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.

14. When performing adjustments or maintenance on the cutter, first lower it to the ground or block it 

securely at a workable height.

15. Never stand between tractor and cutter while tractor is being backed to the cutter hitch.

16. Reduce speed when transporting cutter to avoid bouncing and momentary loss of steering.

17. Use tractor flashing warning lights, day or night, when transporting cutter on road or highways unless 

prohibited by law.

18. In the event that someone other than yourself will operate this equipment we firmly suggest that all

SAFETY references be discussed prior to operation.

19. It is recommended that tractor be equipped with Rollover Protective System (ROPS) or ROPS enclosed 

cab and seat belt.
