2.4 OPERATION CONSIDERATIONS  
1. Know the function of all controls and how to stop  
quickly.  
WARNING  
WARNING  
DO NOT operate on steep slopes.To check a slope,  
attempt to back up it (with the cutter deck down).  
If the machine can back up the slope without the  
wheels slipping, reduce speed and use extreme  
caution. Under no circumstances should the  
machine be operated on slopes greater than 15  
degrees. See Figure 2-4, Page 7 to determine  
approximate slope of area to be mowed. ALWAYS  
FOLLOW OSHA APPROvED OPERATION.  
This machine is equipped with an interlock system  
intended to protect the operator and others from  
injury. This is accomplished by preventing the  
engine from starting unless the deck drive is  
disengaged, the parking brake is on, the steering  
control levers are in the neutral position and the  
operator is in the seat. The system shuts off the  
engine if the operator leaves the seat with the deck  
drive engaged and/or the steering control levers  
are not in the neutral position and the parking  
brake is not engaged. Never operate equipment  
with the interlock system disconnected or  
malfunctioning.  
2. Reduce speed and exercise extreme caution on  
slopes and in sharp turns to prevent tipping or loss  
of control. Be especially cautious when changing  
directions on slopes.

carbon monoxide which can cause brain injury  
and death.  
8. Be alert for holes, rocks, roots and other hidden  
hazards in the terrain. Keep away from any drop-  
offs. Beware of overhead obstructions (low limbs,  
etc.), underground obstacles (sprinklers, pipes, tree  
roots, etc.). Cautiously enter a new area. Be alert for  
hidden hazards.  
17. Keep hands and feet away from cutter blades and  
moving parts. Contact can injure.  
18. Transport the mower using a heavy duty trailer  
or truck. Insure the trailer or truck has all of the  
necessary lighting and markings as required by  
laws, codes, and ordinances. Secure a trailer with a  
safety chain.  
9. Disengage power to cutter deck before backing up.

and then only after observation of the entire area  
behind the mower. If you must mow in reverse,  
maintain a constant lookout to the rear of the  
machine and mow slowly.  
19. Be cautious when loading and unloading onto  
trailers or trucks. Use only a full width ramp. Ramp  
angle should be no more than 15 degrees. Back up  
the ramp and drive down forward.  
20. When transporting the mower, make sure the park  
brake is engaged, the steering control levers are in  
the neutral position, the engine is off with the key  
removed, and the wheels have been blocked.  
10. DO NOT turn sharply. Use care when backing up.  
11. Disengage power to cutter deck before crossing  
roads, walks or gravel drives.  
12. Mow only in daylight or good artificial light.  
21. Tie the mower down securely using straps, chains,  
cable, or ropes. Both front and rear straps must be  
directed down and outward from machine.  
13. NEVER raise the deck with the blades engaged.  
14. Take all possible precautions when leaving the  
machine unattended, such as disengaging the  
mower, lowering the attachments, setting the parking  
brake, stopping the engine, and removing the key.

Section 2  
The potential exposure of the seat belt to severe  
environmental conditions make it crucial to inspect the  
seat belt system regularly.  
20o  
15o  
10o  
It is recommended that the seat belt be inspected on a  
daily basis for signs of damage. Any seat belt system  
that shows cuts, fraying, extreme or unusual wear,  
significant discoloration due to UV exposure, dirt or  
stiffness, abrasion to the seat belt webbing, or damage  
to the buckle, latch plate, hardware or any other obvious  
problem should be replaced immediately.  
5o  
Figure 2-4.  
WARNING  
WARNING  
Failure to properly inspect and maintain the seat  
belt can cause serious injury or loss of life.  
Reduce speed when turning, operating on slopes,  
slick or wet surfaces. Allow extra distance to  
stop.  
Stay off of slopes too steep for safe operation.  
To check a slope, attempt to back up it (with the  
cutter deck down). If the machine can not back  
up the slope without the wheels slipping, do not  
operate the machine on this slope. Under no  
circumstances should the machine be operated  
on slopes greater than 15 degrees. See Figure 2-4  
to determine approximate slope.  
1. Check the full length of the seat belt webbing for  
cuts, wear, fraying, dirt and stiffness. See Figure 2-3.  
2. Check the seat belt webbing in areas exposed to  
ultra violet rays from the sun or extreme dust or  
dirt. If the original color of the webbing in these  
areas is extremely faded and/or is packed with dirt,  
the physical strength of this webbing may have  
deteriorated. If this condition exists, replace the seat  
belt system.  
DO NOT mow near drop-offs, ditches or  
embankments. The machine could suddenly roll  
over if a wheel goes over the edge or if the edge  
caves in.  
3. Check the buckle and latch for proper operation  
and determine if the latch plate is excessively worn,  
deformed, or if the buckle is damaged or cracked.  
See Figure 2-3.  
Operate the machine smoothly, no sudden turns,  
starts or stops on a slope.  
INSPECT BUCkLE  
& LATCH  
NEvER tow on slopes. The weight of the towed  
equipment may cause loss of traction and loss  
of control.  
DO NOT permit untrained personnel to operate  
the machine.
