Why my Kobalt Lawn Mower does not start?
- A
  Angela OsborneAug 2, 2025
  If your Kobalt Lawn Mower doesn't start, there are several potential causes: * The battery might not be charged, so charge the battery. * The battery might not be fully inserted; push it in until it clicks. * There might be grass jammed at the blade; in this case, remove the battery and check under the deck for jams. * The switch could be defective; consider replacing it (Call 1-888- 356-2258). * The battery may require replacement; return the battery to the place of purchase.

Why is my Kobalt KM2040X-06 Lawn Mower so noisy and vibrates?
- A
  Alex BoltonAug 7, 2025
  If your Kobalt Lawn Mower is excessively noisy and vibrates, the motor shaft might be bent. Stop the motor and inspect for damage. Another possibility is that the blade is unbalanced. Repair it before restarting. If the vibration persists, call the toll free helpline (1-888-356-2258).

Why is my Kobalt KM2040X-06 hard to push?
- L
  Lucas WhiteAug 14, 2025
  If your Kobalt Lawn Mower is hard to push, it might be because the grass is too tall, or the cutting height is too low. Try raising the cutting height. Another reason could be that the rear of the mower housing and the blade are dragging in thick grass. Empty the grass clippings from the grass catcher bag.

Why does my Kobalt KM2040X-06 cut the grass unevenly?
- R
  Robert GarciaAug 19, 2025
  If your Kobalt Lawn Mower cuts grass unevenly, it could be due to a rough or uneven lawn. Check the mowing area. Also, the cutting height might not be set properly; move the wheels to a higher setting.

What to do if my Kobalt KM2040X-06 does not mulch properly?
- K
  Krystal Rogers DDSAug 26, 2025
  If the Kobalt Lawn Mower does not mulch properly, it could be because wet grass clippings are sticking to the underside of the deck. Wait until the grass dries before mowing. Alternatively, the mulching plug might be missing; install the mulching plug.
