Leveling the Deck (Side to Side)
If the cutting deck appears to be mowing unevenly, a side to side
adjustment can be performed. Adjust if necessary as follows:
1. With the tractor parked on a firm, level surface, place the
deck lift lever in the top notch (highest position) and rotate
both blades so that they are perpendicular with the tractor.
2. Measure the distance from the outside of the left blade tip to
the ground and the distance from the outside of the right
blade tip to the ground. Both measurements taken should
be equal. If they're not, proceed to the next step.
3. Loosen, but do NOT remove, the hex bolt on the left deck
hanger bracket. See Figure 6-6.

4. Using a wrench, raise or lower the left side of the deck by
turning the adjustment gear. See Figure 6-6.
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 hydrostatic relief
valve open), the brake is in need of adjustment. See your service
dealer to have the brake properly adjusted.
Adjusting the Seat
Refer to the Assembly & Set-Up 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.
Hex Bolt
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 on the top of ball joint. See Figure 6-7.
Figure 6-7
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".
Front tire toe-in can be measured as follows:
1. Place the steering wheel in position for straight ahead
travel.
2. 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.
3. Behind the axle, measure the distance horizontally from
the inside of the left rim to the inside of the right rim. Note
the distance.
4. The measurement taken in front of the axle should be
between 1⁄16" and 5⁄16" less than the measurement taken
behind the axle.
