HILLSIDE OPERATION _____________________________________________________

!
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.
!
CAUTION
Do not operate this mower on slopes greater than
15.7° or a 28% grade.
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.
1. Always mow with the engine at full throttle, but
reduce forward speed to maintain the proper cutting
frequency.
2. Activate traction control (S) as required to improve
weight distribution between decks and mower. [See
4.3].
3. If the mower tends to slide or the tires begin to mark
the turf, angle mower into a less steep grade until
traction is regained or tire marking stops.
4. If mower continues to slide or mark the turf, the
grade 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 tire pressure is essential for maximum traction.
