Hex Bolt
4. Using a wrench, raise or lower the left side of the deck by turning
the adjustment gear. See Figure 27.
The deck is properly leveled when both blade tip measurements
taken earlier are equal. Retighten the hex bolt on the left deck hanger
bracket when proper adjustment is achieved.
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 (and the transmission relief valve open), the
brake is in need of adjustment. See a Sears or other qualified service
dealer to have the brake properly adjusted.
Adjusting the Seat
Refer to the Assembly section of this manual for seat adjustment
instructions.
WARNINg
Before operating the tractor, make sure the seat is engaged in the
seat-stop. Engage the parking brake. Stand behind the machine and
pull back on seat until it clicks into place.

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 of each are threaded into
the ball joint on the left side and the ball joint on the right side:
1. Remove the hex nut below the ball joint. See Figure 28.
2. Thread the ball joint inward to shorten the drag link. Thread the
ball joint outward to lengthen the drag link.
3. Replace the hex 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".
4. Front tire toe-in can be measured as follows:
a. Place the steering wheel in position for straight ahead travel.
b. 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.
c. Behind the axle, measure the distance horizontally from the
inside of the left rim to the inside of the right rim. Note the
distance.
d. The measurement taken in front of the axle should be
between 1⁄16" and 5⁄16" less than the measurement taken
behind the axle.
