4-3 SPINDLE BELT ADJUSTMENT
Belt tensions should be checked every 40 hours to get
maximum life from drive belts and best performance form
the cutter. Belt tension is adjusted by increasing or de-
creasing the length of the spring on the moveable idlers.
For proper belt tension on the mower, the spring
lengths should be set at 2-7/8”. To adjust the spring
length, loosen or tighten the 1/2" hex nuts on the spring
adjustment rod until the correct spring length is reached.
