  Your Gravely Lawn Mower engine may not start due to several reasons. The safety interlock system may not be engaged or could be faulty, the fuel tank might be empty, or the fuel supply could be contaminated. Other potential causes include a discharged battery, poor connection between the battery and cables, loose spark plug wires, or faulty spark plugs. In this case you should check the safety interlock system, fill the fuel tank, replace with clean fuel, charge the battery, tighten or clean the battery and cables, or connect or replace the spark plug wires.

  Poor cutting quality with your Gravely Lawn Mower can stem from several issues: the mower blades might not be level, or the mower deck pitch could be incorrect. The blades could also be dull or faulty, the mowing speed might be too fast, the belt tension or condition could be poor, or the cutting height might be too low. In this case you should level and adjust the pitch of the mower deck, sharpen or replace the mower blades, drive slower when cutting grass, replace the deck drive belt, or avoid setting the cutting height too low.
