RYOBI continues to simplify yardwork with the introduction of the 40-Volt Lithium-Ion 18 2-in-1 Cordless Lawn Mower. Powered by a 4-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. Select your ideal grass height from 1.5 in. to 4 in. with the 7-position single point height adjustment. 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. The compact design features a sleek 18 deck, collapsible handles and upright storage capability, making it ideal for storage in tight spaces. This mower and the included battery are compatible with all RYOBI 40-Volt tools, batteries and chargers. Backed by a 5-Year Limited Warranty.
