GROUND SPEED CONTROL LEVER
ADJUSTMENT
The control levers have three adjustments:
To Adjust Control Lever Height: Pull the levers in
across the operator's lap to their DRIVE positions.
Loosen the mount bolts (D, Figure 30) and raise or lower
the levers to the desired position. Tighten the mounting
bolts.(D).
To Adjust Control Lever End Gap: The control lever
end gap (C, Figure 31) should be adjusted so that the
levers do not contact each other when placed in DRIVE
positions. Loosen the jam nut (A, Figure 30) and adjust
the length of the carriage bolt (B) so that the levers do
not contact each other. Repeat on the opposite side.
Tighten the jam nut (A) to lock the carriage bolt in
position.
To Adjust Operator Clearance: The space between the
operator and the control levers can be increase by
removing the lower mounting bolt (D, Figure 30), pivoting
the lever forward, and reinstalling the capscrew through
the control lever and forward slot (C). Repeat with the
other ground speed lever.
SPEED BALANCING ADJUSTMENT
If the rider veers to the right or left when the ground
speed control levers are in the maximum forward
position, the top speed of the right lever can be balanced
by turning the adjustment knob (E, Figure 30). Loosen
the jam nut and turn the knob COUNTERCLOCKWISE
to increase speed or CLOCKWISE to decrease speed.
Tighten the jam nut when complete.
CUTTING HEIGHT ADJUSTMENT
To increase the mower cutting height (raise the mower
deck), press the top of the mower cutting height switch
(A, Figure 31) To decrease mower cutting height (lower
the mower deck), press the bottom of the switch. Mower
cutting height range is 3-3/4" to 1-1/2". The cutting height
gauge indicates the position of the mower deck. The
cutting height gauge (B) is located on the front of the
rider, just behind the driver's left leg.
