Why is my GreenWorks LMF334 hard to push?

  James AllisonSep 8, 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, so increase the blade height. Another reason could be that the grass catcher and the blade are dragging in thick grass, so empty the grass clippings from the grass catcher.
