3 reasons not to buy

  • The LawnMaster CLMF4819A requires the battery to be charged, and some users had to stop and charge the battery halfway through mowing.

When I turned the mower on its side to get a look underneath to see if it was clogged up (which it wasn't), it began smoking a lot. I immediately unplugged it and ran into my house to grab my iPhone so I could take a video of this mower smoking and post the video here to let future customers see this mower in action before purchasing it. All this happened in about TWO MINUTES after I turned the mower on!!!”
