LEVELING THE DECK
1. Set all tire pressures to the correct specifications.
2. Place machine on a level slab of concrete.

the full lift height position and move the height
adjustment pin to the 4.25” position.
4. Take all the force off the two deck lift springs by
loosening the nuts at the front of each spring.
5. Place a level on the deck, from front to rear. If

DECK BELT REPLACEMENT
Belt adjustment should be checked every 50 hours
to get maximum life and cutting performance from
the mower. Belt tension is adjusted by increasing or
decreasing the length of the spring on the movable
idler. For proper belt tension on the 55”, 61” and 73”
mowers, the spring length should be set at 6”. To
adjust the spring length, loosen or tighten the 1/2”
hex nuts on the spring adjusting rod until the correct
spring length is reached.
