HEED ITS WARNING

Your  

Responsibility

Restrict the use 

of this power machine 

to persons who read, 

understand 

and follow the warnings 

and instructions 

in this manual 

General Operation:

1.  Read, understand, and follow all instructions on the 

machine and in the manual(s) before attempting to 

assemble and operate. Keep this manual in a safe 

place for future and regular reference and for ordering 

replacement parts. 

2.  Be familiar with all controls and their proper operation. 

Know how to stop the machine and disengage them 

quickly.

3.  Never allow children under 14 years old to operate 

this machine. Children 14 years old and over should 

read and understand the operation instructions and 

safety rules in this manual and should be trained and 

supervised by a parent. 

4.  Never allow adults to operate this machine without 

proper instruction. 

5.  To help avoid blade contact or a thrown object injury, 

keep bystanders, helpers, children and pets at least 

75 feet from the machine while it is in operation. Stop 

machine if anyone enters the area.

6.  Thoroughly inspect the area where the equipment is to 

be used. Remove all stones, sticks, wire, bones, toys, 

and other foreign objects which could be picked up 

and thrown by the blade(s). Thrown objects can cause 

serious personal injury. 

7.  Plan your mowing pattern to avoid discharge of 

material toward roads, sidewalks, bystanders and the 

like. Also, avoid discharging material against a wall or 

obstruction which may cause discharged material to 

ricochet back toward the operator. 

8.  Always wear safety glasses or safety goggles during 

operation and while performing an adjustment or 

repair to protect your eyes. Thrown objects which 

ricochet can cause serious injury to the eyes. 

9.  Wear sturdy, rough-soled work shoes and close-fitting 

slacks and shirts. Loose fitting clothes and jewelry 

can be caught in movable parts. Never operate this 

machine in bare feet or sandals. 

10. Be aware of the mower and attachment discharge 

direction and do not point it at anyone. Do not operate 

the mower without the discharge cover or entire grass 

catcher in its proper place.

11. Do not put hands or feet near rotating parts or under 

the cutting deck. Contact with the blade(s) can 

amputate hands and feet.

12. A missing or damaged discharge cover can cause 

blade contact or thrown object injuries. 

13. Stop the blade(s) when crossing gravel drives, walks, 

or roads and while not cutting grass. 

14. Watch for traffic when operating near or crossing 

roadways. This machine is not intended for use on 

any public roadway. 

15. Do not operate the machine while under the influ-

ence of alcohol or drugs. 

16. Mow only in daylight or good artificial light.
17. Never carry passengers.
18. Disengage blade(s) before shifting into reverse. 

Back up slowly. Always look down and behind before 

and while backing to avoid a back-over accident.

19. Slow down before turning. Operate the machine 

smoothly. Avoid erratic operation and excessive 

speed.

20. Disengage blade(s), set parking brake, stop engine 

and wait until the blade(s) come to a complete stop 

before removing grass catcher, emptying grass, 

unclogging chute, removing any grass or debris, or 

making any adjustments. 

21. Never leave a running machine unattended. Always 

turn off blade(s), place transmission in neutral, set 

parking brake, stop engine and remove key before 

dismounting.

22. Use extra care when loading or unloading the 

machine into a trailer or truck. This unit should not 

be driven up or down ramp(s), because the unit 

could tip over, causing serious personal injury. The 

unit must be pushed manually on ramp(s) to load or 

unload properly.

23. Muffler and engine become hot and can cause a 

burn. Do not touch.

24. Check overhead clearances carefully before driving 

under low hanging tree branches, wires, door open-

ings etc., where the operator may be struck or pulled 

from the unit, which could result in serious injury.

25. Disengage all attachment clutches, depress the 

brake pedal completely and shift into neutral before 

attempting to start engine.

26. Your machine is designed to cut normal residential 

grass of a height no more than 10”. Do not attempt to 

mow through unusually tall, dry grass (e.g., pasture) 

or piles of dry leaves. Dry grass or leaves may 

contact the engine exhaust and/or build up on the 

mower deck presenting a potential fire hazard.

27. Use only accessories and attachments approved for 

this machine by the machine manufacturer. Read, 

understand and follow all instructions provided with 

the approved accessory or attachment. 

28. Data indicates that operators, age 60 years and 

above, are involved in a large percentage of riding 

mower-related injuries. These operators should 

evaluate their ability to operate the riding mower 

safely enough to protect themselves and others from 

serious injury. 

29. If situations occur which are not covered in this 

manual, use care and good judgment. Contact your 

customer service representative for assistance.
