SECTION 6: MAKING ADJUSTMENTS
WARNING: Do not at any time make any
adjustment to riding mower without first
stopping engine and disconnecting spark plug
wire.
Brake Adjustment
During normal operation of the rider mower, the brake
is subject to wear. Check the brake periodically by
carrying out the following test:
• Release the parking brake and place the rider
mower in neutral. Depress the brake pedal and try
to roll the rider mower. The tractor should not move.
If the tractor moves, adjust the brake.
WARNING: Do not adjust the brake while the
engine is running. Be sure to block the
wheels of the rider mower before making any
adjustments on the brake cable.
Adjust if necessary as follows:
• Looking at the transmission from the left side of
the tractor, locate the compression spring and
brake disc. See Figure 11.
Figure 11
• Loosen, but do NOT remove, the hex nut found
on the right side of the brake assembly. See
Figure 12.
• Using a feeler gauge, set the gap between the
brake disc and the brake puck at .011".
• Re-tighten the hex nut loosened earlier.
Cutting Height
The deck cutting height adjustment lever is located on
the hood assembly. For a representation of the cutting
height positions, refer to Figure 9 .
• Pull the lever out of the slot and slide it upward or
downward to the desired cutting height.
• Lower the cutting height to mow close to the
ground.
• Raise the deck height to the highest position when
you ride on a sidewalk or a road.
• To mow tall or thick grass, move the cutting height
adjustment lever to the highest position and cut.
Then move the lever to a lower position and cut
again.
Seat Position
The seat position on the rider mower can be adjusted to
maximize the operator’s convenience.
• Stop the mower completely and engage the parking
brake. Turn ignition off.
• Pivot the hood assembly up.
• Loosen the four self-tapping screws on the bottom
of the seat.
• Slide the seat forward or backward in the slot, and
position it as desired. Retighten the four screws.
Blade Brake/PTO
The blade engagement pedal should be adjusted so
that if you depress it about 3/4” from the front of the slot,
it should start engaging the deck belt. The PTO (power
take off) switch is located in the blade brake slot on the
left side of the upper frame. See Figure 12 . The brake
engagement pedal needs to make contact with the PTO
switch for the engine to start.
Under normal operation, the blade engagement pedal
should not require frequent adjustment. However,
perform the following test periodically and make sure
that it is in fine working condition.
• Pivot the hood assembly up and check if there is
enough slack on the deck engagement cable.
• Depress the blade engagement pedal (about 3/4
inch) and check if the belt is engaging.
• If the cable is tight or too loose or the belt is not
engaging, adjust the deck engagement cable.
NOTE: The deck engagement cable will be correctly
adjusted when the cable moves approximately 1/2” off
center line in both directions.
Adjustment to the blade brake will have to be made at
the cable end. See Figure 12.
