Leveling the Deck
NOTE: Check the tractor's tire pressure before perform-
ing any deck leveling adjustments. Refer to Tires in the
Maintaining Your Tractor section of this manual for
information regarding tire pressure.
Front To Rear
The front of the cutting deck is supported by a stabilizer
bar that can adjusted to level the deck from front to rear.
The front of the deck should be between 1/4-inch and
3/8-inch lower than the rear of the deck. 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 the blade nearest the discharge chute so
that it is parallel with the tractor.
2. Measure the distance from the front of the blade tip to
the ground and the rear of the blade tip to the ground.
The first measurement taken should be between
1/4" and 3/8" less than the second measurement.
Determine the approximate distance necessary for
proper adjustment and proceed, if necessary, to the
next step.
3. Loosen the two jam nuts, if present, on the rear side of
the deck stabilizer bracket.
4. Locate the lock nut on the front side of the stabilizer
bracket. See Fig. 5-1. Tighten the lock nut to raise the
front of the deck; loosen the lock nut to lower the front
of the deck.
5. Retighten the two jam nuts loosened earlier when
proper adjustment is achieved.
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 cap screw on
the left deck hanger bracket. See Fig. 5-2.
4. Balance the deck by using a wrench to turn the
Hex Bolt
adjustment gear (found immediately behind the hex
cap screw just loosened) clockwise/up or counter-
clockwise/down. The deck is properly balanced when
both blade tip measurements taken earlier are equal.
5. Retighten the hex cap screw on the left deck hanger
bracket when proper adjustment is achieved.

Parking Brake Adjustment

WARNING: Never attempt to adjust the
brakes while the engine is running. Always
disengage PTO, move shift lever into
neutral position, stop engine and remove
key to prevent unintended starting.
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. See an authorized Troy-
Bilt Service Dealer to have your brakes properly adjusted.
