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:

1.Park the tractor parked on a firm, level surface and place the deck lift lever in the middle position.

2.Rotate the blade nearest the discharge chute so that it is parallel with the tractor.

3.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.

1.Loosen (thread outward) the hex lock nut on the end of the deck hanger rod. See Fig. 6-4.

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 middle 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 Fig. 6-5.

2.To raise the front of the deck, tighten (thread inward) the inner hex nut against the front hanger bracket.

3.To lower the front of the deck, loosen (thread outward) the hex nut, away from the front hanger bracket.

See Fig. 6-4.

4.Retighten the lock nut against the hex nut when proper adjustment is achieved.

4.Using a wrench, raise or lower the left side of the deck by 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.
