SAFETY AND OPERATORS MANUAL
7 OPERATION
7.5 MOWING ON SLOPES
The mower has been designed for good traction and stability under normal mowing conditions. Use caution
when operating on slopes, especially when the grass is wet. Wet grass reduces traction and steering
control.
WARNING
DO NOT USE ON SLOPES GREATER THAN 15°
WARNING
To minimize the possibility of overturning,
the safest method for operating on hills and
terraces is to travel up and down the face of
the slope (vertically), not across the face
(horizontally). Avoid unnecessary turns,
travel at reduced speeds, and stay alert for
hidden hazards.

1. Always mow with the engine at full throttle,
control forward speed using traction foot
pedal to maintain proper cutting.
2. Use weight transfer control as required to
improve weight distribution between decks
and mower.
3. If the mower tends to slide or the tyres begin
to mark the turf, angle mower into a less
steep slope until traction is regained or tyre
marking stops.
4. If mower continues to slide or mark the turf,
the slope is too steep for safe operation. Do
not make another attempt to climb, and back
down slowly.
5. When descending a steep slope, always
lower implements to the ground to reduce the
risk of mower overturning.
Correct tyre pressure is essential for maximum
traction.
