How to Troubleshoot an Ariens Mower

Check the fuel tank to make sure the fuel level is near the full line. Add fuel if necessary.

Check to see whether the spark plug wire is loose. Pull the wire off the spark plug using your fingers. Push the wire back on the spark plug firmly.

Replace the spark plug. Remove the spark plug wire from the spark plug, using your fingers. Use a socket wrench and remove the spark plug. Install a new spark plug and tighten securely, using a socket wrench. Push the spark plug wire onto the spark plug, using your fingers.

Check for excess lawn clippings under the mowing deck. Tilt the mower back and inspect the underside of the deck and blade. If necessary, clear out the clippings with your hands.

Drain the fuel tank if the fuel is old. Place a drain pan on the ground near the fuel tank. Tip the mower slightly so the fuel drains into the drain pan. Dispose of the old fuel according to local regulations. Fill the fuel tank with fresh fuel.
