Slope Operation:

Slopes are a major factor related to loss of control and 
tip-over accidents which can result in severe injury or 
death. All slopes require extra caution. If you cannot 
back up the slope or if you feel uneasy on it, do not mow 
it. 
For your safety, use the slope gauge included as part of 
this manual to measure slopes before operating this unit 
on a sloped or hilly area. If the slope is greater than 15 
degrees as shown on the slope gauge, do not operate 
this unit on that area or serious injury could result.

Do:

1.  Mow up and down slopes, not across. Exercise 

extreme caution when changing direction on slopes.

2.  Watch for holes, ruts, bumps, rocks, or other hidden 

objects. Uneven terrain could overturn the machine. 

Tall grass can hide obstacles.

3.  Use slow speed. Choose a low enough speed 

setting so that you will not have to stop or shift while 

on the slope. Tires may lose traction on slopes even 

though the brakes are functioning properly. Always 

keep machine in gear when going down slopes to 

take advantage of engine braking action.

4.  Follow the manufacturer’s recommendations for 

wheel weights or counterweights to improve stability.

5.  Use extra care with grass catchers or other at-

tachments. These can change the stability of the 

machine.

6.  Keep all movement on the slopes slow and gradual. 

Do not make sudden changes in speed or direction. 

Rapid engagement or braking could cause the front 

of the machine to lift and rapidly flip over backwards 

which could cause serious injury.

7.  Avoid starting or stopping on a slope. If tires lose 

traction, disengage the blade(s) and proceed slowly 

straight down the slope.

Do Not: 

1.  Do not turn on slopes unless necessary; then, turn 

slowly and gradually downhill, if possible.

2.  Do not mow near drop-offs, ditches or embankments. 

The mower could suddenly turn over if a wheel is over 

the edge of a cliff, ditch, or if an edge caves in.

3.  Do not try to stabilize the machine by putting your foot 

on the ground.

4.  Do not use a grass catcher on steep slopes. 
5.  Do not mow on wet grass. Reduced traction could 

cause sliding.

6.  Do not shift to neutral and coast downhill. Over-speed-

ing may cause the operator to lose control of the 

machine resulting in serious injury or death.

7.  Do not tow heavy pull behind attachments (e.g. loaded 

dump cart, lawn roller, etc.) on slopes greater than 

5 degrees. When going down hill, the extra weight 

tends to push the tractor and may cause you to loose 

control. (e.g. tractor may speed up, braking and steer-

ing ability are reduced, attachment may jack-knife and 

cause tractor to overturn).

Towing:

1.  Tow only with a machine that has a hitch designed for 

towing. Do not attach towed equipment except at the 

hitch point.

2.  Follow the manufacturers recommendation for weight 

limits for towed equipment and towing on slopes.

3.  Never allow children or others in or on towed equip-

ment.

4.  On slopes, the weight of the towed equipment may 

cause loss of traction and loss of control.

5.  Travel slowly and allow extra distance to stop.
6.  Do not shift to neutral and coast downhill.
