Troy-Bilt Automatic Lawn Tractor Manuel D’Utilisation

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.

•

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.

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. 

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. 

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.

•

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.

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.
