Powered by a 40-Volt 4 AH Lithium-Ion Battery you can start mowing with the push of a button, instead of having to hassle with extension cords or mixing gas and oil.

The 2-in-1 mulching and side discharge options let you choose which mowing function is best for your yard. Release the mulch door before mowing to fertilize your lawn with clippings or insert the side discharge chute to discharge your clippings to the side.
