  Jonathan ChaseAug 14, 2025
  If your MTD Lawn Mower's engine fails to start, there are several potential causes: * The PTO lever/knob might be engaged. Ensure it is in the OFF position. * The parking brake might not be engaged. Engage the parking brake. * Spark plug wires might be disconnected. Connect the wires to the spark plug. * The throttle control lever might not be in the correct starting position. Place the throttle lever in the CHOKE position. * The fuel tank might be empty or contain stale fuel. Fill the tank with clean, fresh gas. * The fuel line might be blocked. Clean the fuel line or replace the fuel filter, if equipped. * The spark plug might be faulty. Clean, adjust the gap, or replace the plug. * The engine might be flooded. Crank the engine with the throttle in the FAST position.

  If your MTD Lawn Mower engine won't crank, it could be due to a dead or weak battery. Try charging it with a 12-volt automotive-type battery charger at six amps for one hour, or until it's fully charged. Another possible cause is a blown fuse. In this case, replace the fuse with an automotive type fuse of the proper amperage.

  If your MTD Lawn Mower is not mulching grass effectively, consider these possible causes: * The engine speed may be too low. Place the throttle in the FAST (rabbit) position. * The grass might be wet. Avoid mowing when the grass is wet; wait until it's dry. * The grass might be excessively high. Mow once at a high cutting height, then mow again at the desired height, or make a narrower cutting swath. * The blade might be dull. Sharpen or replace the blade.
