  Alan TurnerAug 19, 2025
  If your Gravely Lawn Mower engine won't crank or start, it could be due to several reasons. First, make sure the safety interlock system is properly engaged and not faulty. Next, ensure the fuel tanks are filled and the fuel shut-off valve is open. Check the battery; if it's discharged, charge it. Also, verify that the battery cables are tightly connected and clean. Inspect the spark plug wires to ensure they are connected, and the spark plugs aren't faulty. If these steps don't resolve the issue, it could be a faulty electrical system or engine, in which case you should contact your Gravely Dealer.

  If the PTO or mower blades on your Gravely Lawn Mower do not engage or shut off, there are several potential causes. Ensure the operator presence switch is depressed by sitting on the seat. Check if the electric clutch connector is loose or disconnected, and connect it if necessary. A faulty PTO belt could also be the problem, so consider replacing it. If your model is 915044, 046, 048, or 050, the electric clutch may need adjustment. If these steps don't resolve the issue, it could be a faulty operator presence switch, PTO switch, wires, connectors, or clutch, in which case you should contact your Gravely Dealer.
