Why won't my ALDI Lawn Mower engine start?

  Blake KhanAug 5, 2025
  If your ALDI Lawn Mower engine doesn't start, several factors could be at play. First, ensure the fuel tank isn't empty and refill if needed. Next, check the oil level using the oil filler cap/dipstick; add oil if it's low. Examine the spark plug for dirt or wear, cleaning or replacing it as necessary. Also, make sure the blades aren't hitting the grass by increasing the cutting height. Finally, ensure that the 20V Xfinity Li-ion battery is charged.

  Chris MendozaAug 20, 2025
  If the hard catcher on your ALDI Lawn Mower isn't filling up to the optimum level, consider these points: First, increase the cutting height using the cutting height adjustment lever. If you're mulching and notice piles of grass left behind, increase the cutting depth by one notch. Also, ensure the grass is dry before mowing. Sharpen or replace the blades if they are dull or blunt. Finally, stop the mower and clear the rear discharge chute if it's blocked.
