Things You'll Need
- Spark plug
- Spark plug socket
- Ratcheting wrench
- Tape measure
- New tine set
- 5/16-inch piece of wood
- 9/16-inch wrench
- New foam and paper filter set
Disconnect the spark plug wire to replace the spark plug. Then remove the plug with a spark plug socket and a ratcheting wrench. Replace the old plug with a new one and reattach the spark plug wire.
Note the pattern of the tines on a piece of paper before you begin replacing them so they are reassembled correctly. Inspect the tilling tines every 30 operating hours. Worn tines become narrower and more pointed. The middle gap between a new set of tines is 3 inches. Check the gap with a tape measure. When this gap increases to 5 inches or more, the tines need to be replaced. Tines are simply bolted into place onto the tine shaft via the left-side and right-side tine holders. Loosen the bolts with a ratcheting wrench, remove the old tines and bolt the new tines into place. Replace the tine holders when they show signs of wear.
Replace the reverse disc, which is located just behind the engine, by wedging a piece of wood that is 5/16-inch thick just under the cast iron housing. Then use a 9/16-inch wrench to loosen the bolt holding the reverse disc in place. Put the new disc into position and replace the bolt.
Loosen the wing nut holding the air filter cover in place. Remove and discard the old filters. Slip the new filters into position and replace the air filter cover.
