4 ADJUSTMENTS
4.6

CRUISE CONTROL SWITCH _________________________________________________

If the cruise control does not disengage when brake
pedal is depressed, cruise control switch must be
adjusted.
1. Loosen hardware (F).
2. Adjust switch (G) so contacts are closed with the
brake disengaged and open as soon as the brake
pedal is pressed.
3. Tighten hardware to secure switch and recheck
switch operation.
4.7

MOW SPEED _____________________________________________________________

Cutting quality is better at speeds well below the
transport speed of the mower. An initial mow speed of
seven to eight mph is set at the factory and should be
satisfactory for most cutting conditions. Local turf
conditions however may respond better to a different
speed.
To set mow speed, loosen jam nut (R), and adjust stop
screw up to reduce speed, down to increase speed.
Tighten nut to hold adjustment in place.
4.8

WEIGHT TRANSFER _______________________________________________________

1. Adjusting weight transfer knob affects lowering time
of the lift arms and also affects ground pressure at
each tire.
2. Loosen thin knob (J), and adjust large knob (K) to
increase or decrease cutting unit weight. Knob
adjusts all three mowers simultaneously.
a. Increasing cutting unit weight allows mowers to
follow contours of ground better and reduces
mower ground pressure.
b. Decreasing cutting unit weight increases mower
weight, which increases traction on slopes.
c. Once desired ground pressure has been
obtained, tighten thin knob (J).
NOTICE
If cutting unit weight is set too low, wing cutting units
will not lower to the ground from transport position.
