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 13 . 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 13.

If the belt is slipping when you depress the blade
engagement pedal about 3/4", loosen the two hex
nuts on the cable. See Figure 13.
If the belt is engaging sooner than when the blade
engagement pedal is 3/4" from the PTO switch,
tighten both hex nuts on the cable. See Figure 13.
Repeat the blade engagement test and readjust if
necessary.
Pivot the hood assembly back.
Wheel Alignment
The front wheels should toe-in 1/16-5/16 inch. To adjust
toe-in, follow these steps:
Remove the 3/8'' hex nut which holds the ball joint
to the steering segment. See Figure 14.
Adjust the ball joint in or out until the wheels toe-in
approximately 1/16-5/16" (Dimension ''B'' should
be approximately 1/16-5/16" less than dimension
''A''). See Figure 14.
Replace the ball joint into the steering segment,
and replace the 3/8'' hex nut.

Adjusting the Deck
There are three tests for checking deck levelling on the
rider mower. The results of each test will determine
what kind of levelling, if at all, the equipment needs.
Perform adjustments to the deck on a flat,
IMPORTANT:
level surface. Before continuing with deck adjustment,
check air pressure in all four tires. Recommended air
pressure is 12 psi. Please note that the valve stems on
this rider mower are on the inside of the front wheels
and on the outer side of the rear wheels.
Test 1: Checking Rear Deck Height Adjustment
Lift the hood assembly and remove grass catcher
from the rider mower. Place the deck in the highest
position.
Inspect rear of deck. If the deck is contacting the
cable bracket on the front of the transmission, you
will have to adjust the rear deck height.
