    How to troubleshoot starting issues with my Gravely Lawn Mower?
    • R
      Regina LeeAug 13, 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.

      If you observe poor cutting quality with your Gravely Lawn Mower, the mower deck may not be level or the mower pitch is incorrect. Level and adjust the pitch of the mower deck. The mower blades may also be dull or faulty, so sharpen or replace them.

    Why does the hour meter continue to run on my Gravely ZT1640 when the engine is off?
    • K
      Karen HowellSep 8, 2025
      If the hour meter on your Gravely Lawn Mower continues to run when the engine is not running, the ignition key is likely in the run position with the engine turned off. Turn the ignition key to the off position.
