Leveling The Mower

If the cut is uneven, the mower may need leveling. Unequal or improper tire pressure may also cause an uneven cut. Make sure tire pressure is correct as speci- fied in Checking Tire Pressure.

SIDE-TO-SIDE LEVELING

1.With the mower installed, place the tractor on a smooth, level surface such as a concrete floor. Turn the front wheels straight forward.

2.Check for bent blades and replace if necessary.

3.Place the mower in mid-cut position. Arrange the out- side mower blades so that they are pointing from side-to-side.

4.Measure the distance between the outside tips of each blade and the ground. If there is more than 1/8” (3mm) difference between the measurements on each side, proceed to step 5. If the difference is 1/8” (3mm) or less, proceed to step 6.

ECCENTRIC NUT MODELS

5.See Figure 8. Loosen the outside nut (A). Turn the eccentric nut (B) to raise or lower left-hand side of mower. When mower is level, hold the eccentric nut while tightening the outside nut.

NOTE: 44”, 50”, & 54” Mowers. When using a turbo col- lection system, raise the discharge side of the mower approximately 1/4” (6mm) to compensate for turbo assembly weight. Check the level of the cut grass and adjust the 1/4” (6mm) measurement as necessary for a smooth, even cut.

FRONT-TO-BACK LEVELING

NOTE: 54” mowers have two adjustment rods that should be adjusted simultaneously.

6.Arrange the blades so they face front-to-back.

7.Measure the distance from the ground to the front tip of the center blade, and from the ground to rear tips of left-hand and right-hand blades.

Front tip of the center blade should be 1/4" (6mm) higher than rear tips of left-hand and right-hand blades. If not, proceed with steps 8 - 9.

8.To raise front of mower deck, loosen front nut (B) and turn rear nut (A, Figure 10) against bracket. To lower front of mower deck, loosen rear nut (A) and the bracket will move backwards to lengthen rod.
