DECK BELT ADJUSTMENT
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 49”, 55” and 61”
mowers, the spring length should be set to 7-1/2”
inside hook to inside hook with the deck in 3” cutting
height position. To adjust the spring length, loosen
or tighten the 3/8” hex nuts on the eye bolt until the
correct spring length is reached.
