  There are several reasons why your Gravely Lawn Mower engine might not crank or start: * The safety interlock system may not be engaged or could be faulty. * The fuel tanks might be empty; if so, fill them. * The fuel shut-off valve may be closed; open it. * The battery could be discharged; charge it. * There might be a poor connection between the battery and battery cables; tighten the cables and/or clean the battery and cables. * The spark plug wire(s) may be loose, or the spark plug(s) may be faulty; connect the wire(s) or replace the plug(s).

  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.
