LEVELING THE MOWER DECK
These adjustments should be made on a level surface
with the tires inflated to the correct air pressure.
Level the mower with the slots where the four chains
fasten to the mower mounting brackets (Figure 21).
1. Raise mower deck to its highest position and place
4.75 in. (12.1 cm) tall blocks at each rear corner
and 4.625 in. (11.7 cm) tall blocks at each front
corner.
2. Lower deck onto the blocks.
3. Shut off engine. Engage parking brake. Remove
the ignition key.
4. Loosen the locknuts on the side where the chains
are slack and slide the bolt down the slot until the
chains are tight.
5. Tighten the locknuts.
6. Lift mower and remove blocks.
7. Measure height of deck at each side.
Measurements must be within 3/16 in. (4.76 mm)
of each other.
8. If measurements are out of range, fix by adjusting
chains on low side of deck.
9. Once deck is level side to side, measure height of
deck at middle of front and on both sides of rear.
Front of deck should be 1/8 in. ± 1/8 in. (3.18 ±
3.18 mm) lower than rear.
