Set the seat to the preferred operating position.

•Adjustment lever is located under the front edge of the seat.

•The seat has five inches of front-to-rear adjustment available.

Check factory settings of control levers for the conditions listed above.

NOTE: If control lever adjustments are required, height adjustments should be made prior to angular adjustments.

To adjust the height of the drive control levers:

1.Remove the nuts from the control lever mounting bolts.

See Fig. 6-5.

2.Remove the bolts and control lever and reposition to the second set of holes in the mounting block.

3.Reinstall the bolts and nuts, and tighten to 28-34 ft-lbs.

4.If angular adjustments are also required, nuts can be tightened until snug at this point.

The same adjustments should be made to both sides of the mower.

To adjust the front-to-rear angle of the control levers:

1.Loosen the nuts on the control lever mounting bolts, leaving the bottom one fairly snug. The bottom hole is slotted, allowing the control lever to pivot on the top bolt.

2.Move control lever to the desired angle and tighten the nuts to 28-34 ft-lbs.

NOTE: In the neutral position, the handles of the control levers should be aligned with approximately a one inch gap between the tips. Widen the gap by adding shim washers to the top mounting bolt between the lap bar and the mounting block.

3.Check the results of any adjustments to the conditions described above. Repeat any adjustment procedures as required until all conditions are met.

Leveling the Mower Deck

When correctly adjusted the mower deck should be level side to side, and the front of the deck should be approximately 1⁄4” lower than the rear of deck.

NOTE: Check the tractor’s tire pressure before performing any deck leveling adjustments. See the tire side wall for proper inflation pressures.

1.Park the mower on a flat paved surface, engage the parking brake, shut off the engine, remove the key from the ignition switch, disconnect the spark plug wires.

2.Using the deck lift pedal, position the mowing deck into the highest mowing position.

3.Measure blade-to-ground height at the front tip of the right blade. To obtain an accurate measure, align blades in parallel with mower centerline, (i.e. front to back).

4.Measure blade-to-ground height at the front tip of the left blade. Be sure to measure at the blade tip with the blades arranged in proper position.

5.With a 3⁄4” wrench loosen the lower jam nut of the left side of the lift link. To adjust the side of the deck up or down turn the upper jam nut clockwise (to raise) or counter clockwise (to lower) a few turns. See Fig. 6-6.

6.Measure the blade-to-ground height at the right rear blade tip. Again be sure to measure at the blade tip at the rear of the right blade when aligned along the mower centerline. The blade-to-ground height at the rear of the blade tip should be approximately 1⁄4” higher than the front tip. This is referred to as blade pitch. The same height difference should be true for the left blade, measured front and back.

7.To change the pitch (front to rear), loosen the lower nuts on the rear Lift Links. With a few turns, adjust clockwise (to raise) or counter clockwise (to lower) the upper nuts of the rear Lift Links. Once the deck is adjusted, retighten lower nuts.
