Upgraded Electric Weed Wacker Our weed wacker battery operated has passed the professional design and safety test. The weed trimmer has been upgraded with smoother wheels, a larger mowing area, higher-strength blades and larger-capacity batteries. We have completely solved the problems of the old string trimmer, such as wheels failing to turn, blade breakage and short cutting time. 2 modes (wheel on/wheel off) can be switched freely, allowing you to mow your garden and yard lawn more easily. Powerful Cordless Weed Trimmer The electric weed wacker cordless with wheels all in one: grass trimmer/ lawn edger/ small mower/ brush cutter. Not limited by power cord, you can use it anywhere.
