SECTION 7: MAKING ADJUSTMENTS
WARNING: Never attempt to make any adjustments while the engine is running, except where specified in the operator’s manual.
WARNING: Disconnect the spark plug wire(s) and ground against the engine before performing any adjustments, repairs or maintenance.
LEVELING THE DECK
NOTE: Check the tractor’s tire pressure before performing any deck leveling adjustments. Refer to TIRES in the maintenance section of this manual for further 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
•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.
•From the front of the tractor, loosen the outermost hex lock nut on the end of the deck hanger rod. See Figure 10A.
•Tighten the inner hex nut front against the front hanger bracket to raise the front of the deck; loosen the hex nut to lower the front of the deck. See Figure 10A.
•Retighten the two lock nuts against the inner hex nuts 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:
A |
| B |

| Adjustment Gear |
| FRONT TO REAR | SIDE TO SIDE | Hex Cap Screw |

•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 10B.
•Balance the deck by using a wrench to turn the adjustment gear (found immediately behind the hex cap screw just loosened) clockwise/up or counterclockwise/down.
•The deck is properly balanced when both blade tip measurements taken earlier are equal.
•Retighten the hex cap screw on the left deck hanger bracket when proper adjustment is achieved.
