MTD 393 manual Cleaning Tine Area, Belt Replacement, Reverse Drive Belt, Forward Drive Belt

Cleaning Tine Area

Clean the underside of the tine shield after each use. The dirt washes off the tines easier if rinsed off immediately instead of after it dries. Always towel dry the tiller afterwards and apply a light coat of oil or silicone to prevent rusting or water damage.

IMPORTANT: Never use a "pressure washer” to clean your tiller. Water can penetrate tight areas of the tiller and its chain case and cause serious damage to the unit.

Belt Replacement

Your tiller has been engineered with belts made of special material (Kevlar Tensile). They should not be replaced with an off-the-shelf belt. If belt replacement is required, order belt or belts by part number from your nearest authorized service dealer. See parts list.
