Heavy Duty Finishing Mower
MOWER DECK BELT ADJUSTMENT
Start by removing both belt guards on the mower deck. Loosen the bolts holding the gearbox base plate (#7). Turn the 5/8” hex nuts (#6) on the threaded rod on the base plate until there is enough slack in the belts to slip them off the spindle pulleys. If the belts can be pulled off by sliding them under the large double pulley, no further disassembly is required. If this is difficult, you can create more space by removing the bolts holding on the gearbox mounting plate (#8) in one piece with the gearbox and large pulley. Lift up the mounting plate assembly slightly and slide the belts underneath. When you replace the belts, make sure they are lined up as shown in the drawing. The upper groove in the double pulleys goes around the higher of the single pulleys. The lower grooves of the double pulleys line up with the lower single pulley.
