Drive Belt Replacement

The blade drive consists of three belts, one main drive belt and two wing belts. The main drive belt is tensioned by a fixed idler with a spring adjustment. The wing belts have spring loaded idlers. All belts are very durable but after many hours of use, the belt will show signs of wear. Signs of a worn belt are: squealing when belt is rotating, blades slipping when cutting grass, frayed edges, burn marks and cracks. Replace any belt if any of these conditions are evident. Adjust belt tension on main belt after first 5 hours of operation to assure maximum dura­ bility and thereafter, check tension every 50 hours.
