Why won't my Gravely 915078 engine crank or start?
- D
  durhamsamuelAug 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 filled and the fuel shut-off valve is open. A discharged battery or poor connection between the battery and cables could also be the culprit; in this case, charge the battery or tighten/clean the battery cables. Lastly, inspect the spark plug wires for looseness or faulty spark plugs, addressing as needed. If these steps don't resolve the issue, there may be a faulty electrical system or engine, and you should contact your Gravely Dealer.

  If your Gravely Lawn Mower does not travel in a straight line, start by checking the tire pressure. If the tire pressure is not the issue, try adjusting the steering levers. If the problem persists, there may be an issue with the hydrostatic transmission and/or linkage, and you should contact your Gravely Dealer.

  If your Gravely Lawn Mower unit does not move with the engine running when using the steering levers, first check if the transmission bypass lever is engaged and disengage it. If that's not the issue, the hydrostatic belt may be faulty and need replacement. If the problem continues, the transmission may be faulty, and you should contact your Gravely Dealer.

What to do if PTO or mower blades do not engage or shut off on Gravely Lawn Mower?

  Lauren VazquezAug 28, 2025
  If the PTO or mower blades on your Gravely Lawn Mower do not engage or shut off, start by ensuring the operator presence switch is depressed by sitting on the seat. Also, check if the electric clutch connector is loose or disconnected, and connect it if necessary. A faulty PTO belt could also be the cause, so consider replacing it. If these steps don't solve the problem, the issue might be a faulty operator presence switch, PTO switch, wires, connectors, or clutch, and you should contact your Gravely Dealer.
