How to troubleshoot Gravely Lawn Mower when engine will not crank/start?
- C
  christopher50Aug 15, 2025
  If your Gravely Lawn Mower engine won't crank or start, several issues could be the cause. Begin by checking the safety interlock system to ensure it's properly engaged and functioning. Next, verify that the fuel tanks are adequately filled. A discharged battery can also prevent starting, so ensure it's charged. Inspect the connections between the battery and battery cables, tightening them or cleaning away any corrosion. Also, check the spark plug wires and spark plugs, connecting any loose wires or replacing faulty plugs. If these steps don't resolve the issue, there may be a fault in the electrical system or the engine itself, and it is advisable to contact your Gravely Dealer.

  If the PTO or mower blades on your Gravely Lawn Mower do not engage or shut off, it could be due to several reasons. First, make sure the operator presence switch is depressed by sitting on the seat. A loose or disconnected electric clutch connector can also cause this issue; check and connect it if necessary. Additionally, inspect the PTO belt for any damage and replace if needed. If the problem persists, there may be a faulty operator presence switch, PTO switch, wires, connectors, or clutch, and it is advisable to contact your Gravely Dealer.
