    How to troubleshoot starting issues with my Gravely ZT2348?
    • T
      Thomas ChristensenAug 14, 2025
      If your Gravely Lawn Mower engine won't crank or start, several factors could be at play. First, ensure the safety interlock system is properly engaged and not faulty. Next, check that the fuel tanks are adequately filled and the fuel shut-off valve is open. A discharged battery or poor connection between the battery and cables can also prevent starting, so charge the battery and tighten/clean the connections as needed. Lastly, inspect the spark plug wires for looseness and the spark plugs themselves for faults, replacing if necessary.

    • M
      Melissa SimonSep 8, 2025
