SECTION 6: MAKING ADJUSTMENTS
Never attempt to make any
WARNING:
adjustments while the engine is running,
except where specified in the manual.
WARNING:
Disconnect the spark plug
wire(s) and ground against the engine before
performing any adjustments, repairs or
maintenance.
Parking Brake
WARNING:
Never attempt to adjust the
brakes while the engine is running. Always
disengage PTO, move shift lever into neutral
position, stop engine and remove key to
prevent unintended starting.
Adjust the brake if
1. the tractor does not stop completely when the
brake pedal is completely depressed; or
2. the tractor's rear wheels roll even with the parking
brake applied.
Locate the brake disc on right of the transmission in the
rear of the tractor and adjust as follows:
•
Looking at the transmission from the right side of
the tractor, locate the compression spring and
brake disc.
•
Loosen, but do NOT remove, the hex nut found on
the right side of the brake assembly.
•
Using a feeler gauge, set the gap between the
brake disc and the brake puck at .011".
•
Re-tighten the hex nut loosened earlier.
Seat
WARNING:
Before operating this machine,
make sure the seat is engaged in the seat stop,
stand behind the machine and pull back on
seat until fully engaged into stop.
•
To adjust the position of the seat, move the seat
adjustment lever to the left and slide the seat
forward or rearward. Make sure seat is locked into
position before operating the tractor.
Steering
Adjust the steering drag links if
1. the tractor turns tighter in one direction than the
other; or
2. while the ball joints are being replaced.
Adjust the drag links so that equal lengths are threaded
into the ball joints on the left and the right respectively.
•
Loosen the jam nut found on the drag link at the
rear of the ball joint. See Figure 9.
Hex Nut and
Lock Washer
Axle
•
Remove the hex nut and lock washer on the top of
ball joint. See Figure 9.
•
Thread the ball joint toward the jam nut to shorten
the drag link. Thread the ball joint away from the
jam nut to lengthen the drag link.
•
Replace hex nut and lock washer and retighten the
jam nut after proper adjustment is achieved.
NOTE: Threading the ball joints too far onto the drag
links will cause the front tires to "toe-in" too far. Proper
toe-in is between 1/16" and 5/16".
Front tire toe-in can be measured as follows:
•
Place the steering wheel in position for straight
ahead travel.
•
In front of the axle, measure the distance
horizontally from the inside of the left rim to the
inside of the right rim. Note the distance.
•
Behind the axle, measure the distance horizontally
from the inside of the left rim to the inside of the
right rim. Note the distance.
•
The measurement taken in front of the axle should
be between 1/16" and 5/16" less than the
measurement taken behind the axle. Adjust if
necessary.
Leveling the Deck
NOTE: Check the tractor's tire pressure before
performing any deck leveling adjustments. Refer to
Tires on page 24 for information regarding tire pressure.
Front To Rear
The front of the cutting deck is supported by a stabilizer
bar that can adjusted to level the deck from front to rear.
The front of the deck should be between 1/4-inch and
3/8-inch lower than the rear of the deck. Adjust if
necessary as follows:

Pivot Bar
Drag Link
Jam Nut
Ball Joint
