Mowing Speed; Hillside Operation - Jacobsen LF 550 Serie Manual De Instrucciones

MOWING SPEED __________________________________________________________

Cutting quality is better at speeds well below the transport
speed of the mower. An initial mow speed of 7 MPH (11 kph)
is set at the factory and should be satisfactory for most
cutting conditions. Local turf conditions however may
respond better to a different speed.

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 19°
angle or 34% 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. 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.
2. 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.
Correct tire pressure is essential for maximum traction.
