  Your Snapper Lawn Mower engine might not start due to several reasons. The blade engagement switch might be in the “ON” position, so move it to “OFF”. Ensure the park brake is set. The fuel tank could be empty, so fill it with fresh fuel. The engine might need choking, so move the engine speed control to “CHOKE”. Check if the spark plug wire is disconnected and place it onto the spark plug. The battery might be weak or dead, so service it.

  If the starter of your Snapper Lawn Mower won't crank the engine, it could be due to a dead battery, so service the battery. A blown fuse could also be the cause, so replace the fuse. Check for loose or corroded electrical connections and clean them to ensure good contact. If the starter spins without engaging, release the start key and repeat the attempt; if it continues, contact the Engine Dealer.

  Your Snapper Lawn Mower engine might stall after running because the operator is not in the seat, so sit in the operator’s seat. Also, the engine speed control might be in the “CHOKE” position, so move it to “FAST”. Check if the fuel tank is empty and fill it to the proper level. The engine air pre-cleaner and/or air cleaner might be dirty, so clean them. The spark plug might be defective or the gap improperly set, so service the spark plug.

  If your Snapper Lawn Mower is cutting grass improperly, check the following: ensure even tire pressure, adjust the cutting height if it's too low or high, move the engine speed control to “FAST” if the engine speed is too slow, and reduce forward speed if it's too fast.
