4-3 SPINDLE BELT ADJUSTMENT

Belt tensions should be checked every 40 hours to
get maximum life from drive belts and best perfor-
mance from the cutter. Belt tension is adjusted by
increasing or decreasing 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". (Figure 4-2) 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.
