  Sean SmithAug 19, 2025
  If your Gravely Lawn Mower engine won't start or is hard to start, there are several possible causes. Ensure the control levers are in the neutral position and that the neutral position switches are fully depressed. Check that the ignition switch is in the proper position and the PTO is disengaged. Make sure the fuel tank isn't empty and that the fuel isn't stale; if it is, replace it. Inspect and replace a plugged fuel filter or a plugged air intake filter. Check the spark plug wire to ensure it's connected and tight, and verify the spark plug is gapped correctly. Replace any blown 20-amp fuse, and charge or replace the battery if it's discharged. Inspect and repair any faulty relay connections, and make sure the choke is adjusted correctly.
