3.6 CRUISE CONTROL SWITCH_________________________________________________
1. If the cruise control does not disengage when brake
pedal is depressed, loosen hardware (D) and slide
switch so roller (E) is centered on bolt (F) .
2. Loosen hardware and adjust bolt (F) so head makes
contact with roller (E) and activates switch.

3.7 FUEL SOLENOID __________________________________________________________
1. Adjust rod (H) so fuel solenoid locks into hold
position when ignition key is turned to the START
and returned to the RUN position. Maintain a 1/32 -
1/16 in. (0.8 - 1.6 mm) gap between lever and boss
when ignition key is in the OFF position.
Note: Fuel solenoid will not activate without parking
brake engaged, and PTO Switch disengaged. Turn key
to Start position only long enough to activate solenoid.
Do not start engine without operator in seat.

3.8 GROUND PRESSURE ______________________________________________________
1. Adjusting ground pressure 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
tractor ground pressure.
b. Decreasing cutting unit weight increases tractor
weight, which increases traction on slopes.
c. Once desired ground pressure has been
obtained, tighten thin knob (J) .
Note: If cutting unit weight is set too low, wing cutting
units will not lower to the ground from transport position.
