Troubleshooting your Swisher mower attachment when its engine won't start

• When you can't start your mower attachment's engine, make sure the tank has fuel and that the fuel is fresh; stale fuel can become watery and won't ignite well. Tune up the mower's engine to give it the best chance of starting. Check the spark plug and replace it if it's covered with oil or other deposits.
• If your mower attachment engine uses a battery, charge or replace the battery if it won't power the starter to spin the engine. If you have to pull the starter rope to start the engine, replace the recoil starter if it doesn't spin the engine when you pull the rope. Replace the starter rope if it's broken.
• Replace the safety switch or the ignition coil if the spark plug isn't getting current through the ignition system. The engine won't start if you hit a rock or stump and shear off the flywheel key, so replace the flywheel key if it's broken.
• Carburetor problems often prevent a mower engine from starting. Replace or rebuild the carburetor if it's clogged.

Common replacement parts for Swisher mower attachments

• Blades. The cutting blades attach to the blade hub under the mower deck and spin to cut the grass during mowing.
• Spark plug. The spark plug ignites the air and fuel mixture in the cylinder to start the lawn mower attachment engine. If the engine runs rough or is hard to start, check the spark plug and replace it.
• Air filter. The mower attachment engine's air filter removes contaminants from air before it reaches the engine, to help reduce engine wear and improve efficiency.
• Flywheel key. The flywheel key is a small metal rectangle that keeps the crankshaft and flywheel aligned when you tighten the flywheel nut. To protect more expensive components from damage, the flywheel key is designed to shear if the mower attachment blade hits an object hard enough to make the flywheel slip out of alignment with the crankshaft.
