MOWER ADJUSTMENTS

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. To achieve proper mower levelling, perform Side-To-Side Leveling, Front-To-Back Leveling and Transport Height Adjustment procedures, in order, as follows.

Adjustments

WARNING

Before checking mower, shut off PTO and engine. Allow all moving parts to stop. Remove ignition key, then disconnect the spark plug wire and fasten it away from the spark plug.

Side-To-Side Leveling

1.With the mower installed, place the rider 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.Loosen nut (C, Figure 26) so trailing arms are loose. Mower must be resting on rollers with no weight on trailing arms.

4.Use the Dial-A-CutTMControl (E, Figure 27) and place mower in mid-cut position by aligning front edge of mower lift lever (A) with number 2 or 3 on quadrant scale. Make sure mower lift lever is in down position.

5.Make sure rear rollers (C, Figure 28) are on the ground. If not, refer to Transport Height Adjustment.

NOTE: If rollers do not rest on the ground and it is necessary to perform transport height adjustment, it is necessary to perform transport height adjustment again after all leveling procedures are completed.

6.Position blade(s) side-to-side and measure distance from outside tip of blade(s) to ground. Measurement should be equal (within 1/8”).

7.See Figure 28. On left side of mower, make sure eccentric nut is in correct position as shown. Loosen outside nut (A) and rotate eccentric nut (B) so that flat side with hole closest to it is towards the rear. Tighten outside nut (A) while holding eccentric nut (B).

8.On right side of mower, loosen outside nut (A). Turn eccentric nut (B) counterclockwise to raise side of mower, or clockwise to lower right hand side of mower.

NOTE: Do not turn eccentric nut more than 1/4 turn in either direction. When adjusted beyond 1/4 turn, nut will move mower in opposite direction than when starting adjustment.

9.When adjustment is correct, hold eccentric nut (B) and tighten nut (A) to 30 ft-lbs. Check measurement on both sides of mower.
