7.9 MOWING ON SLOPES______________________________________________________
The mower is made to have good traction and to have good
balance. Operate the mower with caution when you drive on a
gradient. If you drive on wet grass, the traction and steering
control of the mower is decreased.
1. Always cut the grass with the engine at full throttle.
Control the forward speed with the traction pedal to
keep the correct performance.
2. Activate the traction control to improve the weight
distribution between the cutting units and the mower.
3. If the mower moves to the side or the tires damage the
turf, drive the mower on a slope with a decreased
angle.
4. If the mower continues to move to the side and damage
the turf, the slope is at an angle that is not safe. Do not
continue to drive toward the top of the slope. Carefully
drive toward the bottom of the slope.
5. When you drive toward the bottom of a slope with a
high angle, lower the cutting units to the ground. This
procedure makes sure the mower does not turn upside
down.
6. Correct tire pressure is necessary for maximum traction.
Front - 12 psi (0.83 BAR)
Rear - 12 psi (0.83 BAR)
WARNING
When you operate on the slopes, lock the ROPS frame in
the vertical position and the seat belt fastened. Do not
operate on the slopes with the ROPS in the folded
position.
To make sure that the mower does not turn over, the safest
method to drive on a slope is to drive vertically. You must
not drive across the face horizontally. Travel at a slow
speed and do not make the turns that are not necessary.
Check for hazards on the road that are not visible to the
drivers. Keep the cutting units lowered when you operate
on the slopes.
CAUTION
Do not operate the mower on the slopes greater than 18.4°
or a 33% slope.
