Grass Bag (optional kit)
Remove the grass bags from the hopper frame, and wash them
with a garden hose or pressure washing equipment. Allow the
bags to completely dry before storage.
After washing the lawn tractor, wipe dry all accessible surfaces.
Start the engine outdoors, and let it run until it reaches normal
operating temperature to evaporate any water remaining on the
engine.
While the engine is running, sit on the operator's seat and operate
the PTO clutch lever to expel water from the blade pulleys,
spindles, and other mower deck items. Allow the blades to spin for
several minutes to ensure that no water remains.
Stop the engine and allow it to cool.
After the lawn tractor is clean and dry, touch up any damaged
paint and coat other areas with a light film oil. Lubricate the
throttle cable core with a silicone spray lubricant.
