  Michael LopezAug 13, 2025
  Your GreenWorks Lawn Mower might stop during mowing due to several reasons: the blade height might be too low, so try increasing it; the battery pack may be out of power, so ensure to charge it; grass clippings might be attached to the deck or the blade, in this case, remove the battery pack and check the deck; or the machine's operation temperature might be too high, so allow the machine to cool down.

  If your GreenWorks Lawn Mower doesn't start, it could be due to a low battery. Try charging the battery pack. Alternatively, the battery key might not be inserted; make sure to put it in. If neither of these solutions works, the bail switch may be defective and need replacement.

  If your GreenWorks Lawn Mower does not mulch correctly, wet grass clippings may be sticking to the deck, so wait until the grass dries before mowing. Alternatively, the mulch plug might be missing; install the mulch plug.

Why is my GreenWorks Lawn Mower so hard to push?
- P
  Paul SosaSep 1, 2025
  If your GreenWorks Lawn Mower is hard to push, it could be because the grass is too tall or the blade height is too low. Increase the blade height to resolve this. Another reason could be that the grass catcher is full and the blade drags in thick grass, so empty the grass clippings from the grass catcher.

  Loretta EllisSep 5, 2025
  If there is a high vibration in your GreenWorks Lawn Mower, the blade might be unbalanced or worn. If so, replace the blade. Another possible cause is a bent engine shaft. If you suspect this: 1. Stop the engine. 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.
