Troy-Bilt Automatic Lawn Tractor Making Adjustments, Leveling the Deck, Parking Brake Adjustment

SECTION 6: MAKING ADJUSTMENTS

WARNING: Never attempt to make any adjustments while the engine is running, except where specified in the operator’s manual.

Leveling the Deck

NOTE: Check the tractor’s tire pressure before performing any deck leveling adjustments. Refer to Tires section 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:

•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.

•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.

•Loosen the jam nut(s),on the rear side of the deck stabilizer bracket.

•Locate the lock nut(s) on the front side of the stabilizer bracket. See Figure 13. Tighten the lock nut(s) to raise the front of the deck; loosen the lock nut(s) to lower the front of the deck.

•Retighten the jam nut(s) 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:

•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.

•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.

•Loosen, but do NOT remove, the hex cap screw on the left deck hanger bracket. See Figure 14.
