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, stay alert for hidden hazards, and drop
offs.
!
CAUTION
Do not operate this mower on slopes greater than 14°
angle or 25% grade.
The mower has been designed for good traction and
stability under normal mowing conditions; however, use
caution when operating on slopes, especially over rough
terrain, or 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 for safe operation.
2. 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.
3. If mower continues to slide or mark the turf, the grade is
too steep for safe operation. Do not make another
attempt to climb, back down slowly.
4. When descending a steep slope, always lower
implements to the ground to reduce the risk of mower
overturning.
5. Correct tire pressure is essential for maximum traction.
Front - 16 to 20 psi (1.10 to 1.38 BAR)
Rear - 10 to 12 psi (0.69 to 0.83 BAR)
6. If additional traction is required, adjust the weight
transfer knob as described in the Parts and
Maintenance manual.
