SECTION 5: MAKING ADJUSTMENTS
Seat
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.
Parking Brake Adjustment
If the tractor does not come to a complete stop when the
brake pedal is completely depressed, or if the tractor’s
rear wheels can roll with the parking brake applied, the
brake needs adjustment. The brake disc is located on
the right side of the transmission in the rear of the
tractor. Adjust if necessary as follows:
1.
Looking at the transmission from the right side of the
tractor, locate the compression spring and brake disc.
See Figure 7.
2.
Carefully remove the cotter pin from the crown nut on
the right side of the brake assembly.
3.
Using a feeler gauge, check the gap between the
brake disc and the brake puck. Proper gap is.011".
4.
Tighten the crown nut until the proper gap is achieved.
5.
Insert a replacement cotter pin into the crown nut.
Steering
If the tractor turns tighter in one direction than the other,
or if the ball joints are being replaced due to damage or
wear, the steering drag links may need to be adjusted.
Adjust the drag links so that equal lengths are threaded
into the ball joints on both sides.
1.
Loosen the jam nut on the drag link at the rear of the
ball joint. See Figure 8.
2.
Remove the hex nut and lock washer on top of the
ball joint. See Figure 8.
3.
Thread the ball joint
toward
the jam nut to shorten the
drag link.
4.
Thread the ball joint
away
from the jam nut to
lengthen the drag link.
5.
Replace hex nut and lock washer and retighten the
jam nut after proper adjustment is achieved.
NOTE:
Threading the ball joints too far on to the drag links will cause the front tires to "toe-in" too far. Proper toe-in is
between 1/16" and 5/16".
WARNING:
Never attempt to make any adjustments while the engine is running, except where specified
in the operator’s manual.Disconnect spark plug wire(s) and ground against the engine before performing
any adjustments, repairs or maintenance.
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.
WARNING:
Never attempt to adjust the
brakes while the engine is running. Always
disengage PTO, stop engine and remove key
to prevent unintended starting.
