Troy-Bilt Automatic Lawn Tractor - Manual (Page 19)

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 is in need of adjustment. The brake
disc can be found on the right side of the transmission
in the rear of the tractor. Adjust if necessary as follows:
• Looking at the transmission from the right side of
the tractor, locate the compression spring and
brake disc. See Figure 15.
Figure 15
• Loosen, but do NOT remove, the hex nut found on
the right side of the brake assembly. See Figure 15.
• 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 Adjustment
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.
Quick-Adjust Seat (if so equipped)
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.
Knob Adjustment Seat (if so equipped)
To adjust the position of the seat on models so
equipped, loosen the two knobs on the bottom of the
seat. Slide the seat forward or backward as desired.
Retighten the two knobs.
Steering Adjustment
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 joint on the left side and the ball joint on the
right side:
• Loosen the jam nut found on the drag link at the
rear of the ball joint. See Figure 16.
Figure 16
• Remove the hex lock-nut on the top of ball joint.
See Figure 16.
• 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 lock-nut 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.
