Adjustments
WARNING! Shut the engine off, remove the
ignition key and engage the parking brake before
making adjustments. Protect your hands by using
heavy gloves when handling the blades.
NOTE: Check the tractor’s tire pressure before performing
any deck leveling adjustments. Refer to Tires on page 25 for
information regarding tire pressure.
Leveling the Deck (Front To Rear)
The front of the cutting deck is supported by a stabilizer bar that
can be adjusted to level the deck from front to rear. The front of
the deck should be between 1⁄4” and 3⁄8” lower than the rear of the
deck. Adjust if necessary as follows:
Park the tractor parked on a firm, level surface and place 1.
the deck lift lever in the middle position.
Rotate the blade nearest the discharge chute so that it is
2.
parallel with the tractor.
Measure the distance from the front of the blade tip to the
3.
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.
Loosen (thread outward) the hex lock nut on the end of the 1.
deck hanger rod. See Fig. 6-4.
To 2. raise the front of the deck, tighten (thread inward) the
inner hex nut against the front hanger bracket.
To
3. lower the front of the deck, loosen (thread outward) the
hex nut, away from the front hanger bracket.
See Fig. 6-4.
Retighten the lock nut against the hex nut when proper
4.
adjustment is achieved.
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:
With the tractor parked on a firm, level surface, place the 1.
deck lift lever in the middle position and rotate both blades
so that they are perpendicular with the tractor.
Measure the distance from the outside of the left blade
2.
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.
Loosen, but do NOT remove, the hex bolt on the left deck
3.
hanger bracket. See Fig. 6-5.
Using a wrench, raise or lower the left side of the deck by 4.
turning the adjustment gear. See Fig. 6-5.
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 Troy-bilt
dealer to have the brake properly adjusted.
Adjusting the Seat
Refer to the Set-Up and 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.
