    What to do if my Gravely Pro-Turn Z 48 engine runs rough?
    • K
      Kathryn PriceSep 12, 2025
      If the engine of your Gravely Lawn Mower runs rough, the choke control knob might be in the 'on' position. If so, move the knob to the 'off' position. Additionally, a plugged air filter cartridge could be the cause, so clean or replace it. If neither of these solutions resolves the issue, the engine itself may be faulty, and you should contact your Gravely dealer.

      If your Gravely Lawn Mower does not drive, one potential cause is that the transaxles are bypassed. If this is the case, engage the levers. It's also possible that the transaxle drive belt is faulty, or that the transaxles themselves are faulty, which would require contacting your Gravely dealer.

      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.

    Why is my Gravely Lawn Mower's cutting quality so poor?
    • C
      Cynthia BullockAug 28, 2025
      If your Gravely Lawn Mower exhibits poor cutting quality, several factors could be responsible. First, the mower blades might not be level, or the mower deck pitch could be incorrect. It's also possible that the mower blades are dull or faulty, requiring sharpening or replacement. Another factor could be mowing speed is too fast, so try driving slower when cutting grass. Also, belt tension or condition might be poor, requiring replacement of mower belts. Finally, the cutting height might be too low, so avoid setting the height of cut too low, and for very tall grass, mow twice.

    • S
      Shawn RiveraAug 29, 2025
      If the PTO malfunctions on your Gravely Lawn Mower, it could be due to a few reasons. The operator presence switch might not be engaged; make sure to activate it by sitting on the operator seat. It's also possible that the operator presence switch itself is faulty. Another cause could be a faulty PTO belt, which would need replacement. In some cases, the PTO switch, wiring, connectors, or clutch might be faulty, which would require contacting your Gravely dealer.

    • M
      Michael PriceSep 18, 2025
      If the blades on your Gravely Lawn Mower do not stop within 5 seconds, it indicates that the clutch brake plates are worn. Try reversing the clutch brake plates. If they have already been reversed, replace the clutch.

    Why does my Gravely Lawn Mower engine overheat?
    • K
      Kimberly StewartSep 12, 2025
      If your Gravely Lawn Mower is overheating, it might be due to a low engine oil level, so add engine oil. Another potential cause is plugged cooling fins, so clean the engine. If the problem persists, the engine itself may be faulty, and you should contact your Gravely dealer.
