turning when the nut is being removed (Fig. 13).
4. Loosen the blade nut using a 14 mm wrench or socket (not provided) (Fig. 13).
5. Remove the blade nut and blade.
6. Make certain the fan assembly is pushed completely against the motor shaft.

ends pointing up toward the mower deck and not down toward the ground.
8. Thread the blade nut on the shaft and finger tighten.
9. Torque the blade nut down using a torque wrench (not provided) to ensure the bolt is properly
tightened (Fig. 14).
