Deck

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.Locate the two lock nuts on the opposite side of the stabilizer bracket. See Figure 9. Tighten the lock nuts to raise the front of the deck; loosen the lock nuts to lower the front of 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 cap screw on the left deck hanger bracket. See Figure 10.

4.To balance the deck turn the adjustment gear, located immediately behind the hex cap screw, clockwise/up or counterclockwise/down. See Figure 10. You will need an adjustable wrench for this step.

5.The deck is properly balanced when both blade tip measurements, taken earlier, are equal.

6.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. The brake disc can be found on the right side of the transmission in the rear of the tractor. Adjust if necessary as follows:
