  Dustin MontoyaAug 5, 2025
  If your GreenWorks Pro Lawn Mower stops during mowing, there are several potential causes. First, the blade height might be too low, so try increasing it. Second, the battery pack may be out of power; in that case, charge the battery pack. Third, grass clippings might be stuck to the deck or blade, so remove the battery pack and check the deck. Finally, the machine's operating temperature could be too high, so allow the machine to cool.

  A high vibration in your GreenWorks Pro Lawn Mower could be due to an unbalanced or worn blade, in which case you should replace the blade. Alternatively, the motor shaft might be bent. If this is the case: 1. Stop the motor. 2. Remove the safety key and battery pack. 3. Disconnect the power source. 4. Inspect for damage. 5. Repair the machine before you start it again.

  If your GreenWorks Pro Lawn Mower is hard to push, it could be because the grass is too tall, or the blade height is too low; try increasing the blade height. It could also be that the grass catcher and the blade are dragging in thick grass, so empty the grass clippings from the grass catcher.

  If your GreenWorks Pro Lawn Mower does not mulch correctly, it might be because wet grass clippings are sticking to the deck. Wait until the grass dries before mowing. Another possibility is that the mulch plug is missing; install the mulch plug.

  If your GreenWorks Pro Lawn Mower cuts grass unevenly, it could be because the lawn is rough, so examine the mowing area. Another reason might be that the blade height is not set correctly, so move the wheels to a higher position.
