12 Inch Bolo Tine - Right Hand
Part #742-04224-0637
Built for a right-hand position, this 12-inch bolo tine curves to cut and lift soil as the tiller moves. The black coating helps protect the metal during storage and normal use. This is one outer tine, not a complete set. Check the machine diagram for its exact place because ?right-hand? can refer to the tine layout, not simply the side you see. Stop the engine, close the fuel valve, and disconnect the spark plug. Wear sturdy gloves, mount the tine with its curve facing the shown direction, and secure it with sound hardware.

Stop the engine, let it cool, close the fuel valve, and disconnect the spark plug lead. Support the tiller securely, wear heavy gloves, and inspect the mounting bolts and tine holder before fitting the replacement.
