If you are unsure about these procedures, take the unit to an MTD authorized service dealer. NOTE: Maintenance, replacement, or repair of the emission control devices and system may be performed by an MTD authorized service dealer.

TINE REMOVAL AND REPLACEMENT WARNING: To prevent serious personal injury, always wear heavy gloves when handling the tines. NOTE: All installation instructions are explained from the operating position. All 4 tines should be replaced at the same time because they will wear evenly through normal use. Work on one side at a time. 1. Stop the engine and allow it to cool. Grasp the spark plug wire firmly and pull the cap from the spark plug. 2. Lay the cultivator back on a flat level surface with the handles touching the ground so that the cultivator is in a horizontal position. NOTE: It may be necessary to wash any dirt off the tines and shaft for easier tine removal. 3. Remove the click pins from each end of the tine shaft (Fig. 8). Slide the tines off of the shaft. 4. Clean and oil the shaft. 5. Slide on the new tines with the hubs facing in towards each other (Fig. 8). NOTE: Each tine has a convex side.
