Deck leveling and height adjustment

The mower deck has three areas that may need to be checked and adjusted periodically. Before considering any mower deck leveling adjustments, check that the tire air pressure is within the specified range.

Deck level adjustments

Leveling the deck must be done in the following manner and order:

1.Check tire pressures to make certain they are properly inflated before starting to level deck. The recommended pressures are as follows: Drive wheels tire pressure ........................................8 - 10 psi Gauge wheels tire pressure.......................................8 - 10 psi

WARNING: Stop engine. Make sure deck clutch switch is in the down (OFF) position. Remove ignition key. Place control levers in the brake position before leaving machine.

2.Park the unit on a flat surface.

3.Raise deck and place 3" of blocking under all 4 corners of the deck (Fig. 9-34). This will set the cutting height at 3 ¼ ". NOTE: Back of deck will automatically be set ¼" higher.

4.Set cutting height at 3 ¼" in the height indicator by placing the height adjusting stop in the 3" hole, and turning the height stop so that the flat side is against the stop handle. Fig. 9-35

5.Clamp the height adjusting stop against the stop handle (Fig. 9-35). This will assure that the height will not move during the setting process. Otherwise, spring pressure from the deck lift springs will tend to pull the stop away from the handle.

6.Loosen all nuts on the deck lift threaded rods, and the hardware on the adjuster (on the right front), until all the deck lift chains are loose, and the deck is sitting tightly on all four blocks. Fig. 9-36, 9- 37, 9-38

7.Loosen the two nuts on the front of height indicator so that the foot pedal is free. Fig. 9-39

8.Start the leveling process on the left front of the tractor.

9.Set the amount of threads protruding on the deck lift rod from the lift block at approximately 1". Fig. 9-40

10.Jam both nuts against the block.

11.Push or pull on the deck lift foot pedal until the chain on the left front just becomes tight, making sure that the deck stays tight

against the 3" block.

12.While keeping the chain tight, tighten the nuts against the deck lift block on the height indicator rod. Fig. 9-39

13.Go to the right front of the tractor.

14.Loosen the 5/16" jam nut on the adjuster lift chain (Fig. 9-38), and back the adjuster bolt out to allow the adjuster to move up and down freely.

15.Be sure that adjuster is free to move up and down.

16.Tighten the adjuster bolt until the chain just becomes tight, making sure that the deck stays tight against the 3" block.

17.Tighten the adjuster bolt jam nut to prevent the adjuster bolt from moving. Fig. 9-38

18.Tighten the hardware holding the chain and adjuster onto the deck lift arm.

19.Go to the right rear of the tractor.

20.Make sure that there is still slack in the chain. If not, loosen the two nuts on the block holding the threaded rod until there is slack in the deck lift chain. Fig. 9-38

21.Tighten the appropriate nut until the chain just becomes tight, making sure that the deck stays tight against the 3" block.

22.Tighten the other nut on the opposite side of the block, and jam them tightly together against the block.

23.Go to the left rear of the tractor.

24.Make sure that there is still slack in the chain. If not, loosen the two nuts on the block holding the threaded rod until there is slack in the deck lift chain. Fig. 9-36

25.Tighten the appropriate nut until the chain just becomes tight.

26.Tighten the other nut on the opposite side of the block, and jam them tightly together against the block.

27.Compress the deck lift assist springs so that there is 1” of space between the front nut on the spring and the rear nut on the deck lift block (Fig. 9-40). Typical both sides.

28.When completed, all chains will be tight, and deck cutting height will be set to the deck height indicator.
