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.
