Why won't my Gravely HD 48 CARB engine start?
- A
  Andrew RiversAug 23, 2025
  If your Gravely Lawn Mower engine isn't starting, several factors could be at play. It could be due to an unengaged or faulty Safety Interlock System, an empty fuel tank, contaminated fuel supply, or a discharged battery. Also, check for poor connections between the battery and its cables. Loose spark plug wires or faulty spark plugs could also be the reason. In the first instance, check the Safety Interlock System. If the fuel tank is empty, refill it. If the fuel supply is contaminated, replace it with clean fuel. If the battery is discharged, charge it. If the connection between the battery and battery cables is poor, tighten and/or clean the battery and battery cables. If the spark plug wires are loose, connect them or replace the spark plugs.

  Sara Gonzalez DDSAug 27, 2025
  If your Gravely Lawn Mower does not drive, make sure that the transaxles are engaged by their levers. If the levers are engaged, but the unit still doesn't drive, the transaxle drive belt may be faulty, or the transaxles themselves may be faulty, in which case you should contact your Gravely dealer.

How to improve the cutting quality of my Gravely Lawn Mower?
- M
  Mark HallAug 25, 2025
  If you notice poor cutting quality with your Gravely Lawn Mower, several factors could be the reason. The mower blades might not be level, or the mower deck pitch could be incorrect. The mower blades could be dull or faulty. The mowing speed could be too fast, or the belt tension or condition might be poor. Also, the cutting height might be too low. Level and adjust the pitch of the mower deck. Sharpen or replace the mower blades. Drive slower when cutting grass. Replace the mower belts. Avoid setting the cutting height too low; for very tall grass, mow twice.
