Visit the interactive landing page to learn more about this mower. Experience a new level of power with the RYOBI 40-Volt 20" Lawn Mower. The brushless motor in this unit comes equipped with load sensing technology, allowing it to detect and deliver the power needed for optimal cutting speed. This will help the mower power through thick grass without getting bogged down and reduce power when it is not needed for extended battery life. Equipped with a large 20 in. deck and the option to mulch or bag clippings, you can get the job done quicker and just the way you like! Additionally, the push-button start and the 7-position single-point height adjustment make this mower easy to set up and use. High intensity LED lights and a whisper quiet mower allow you to cut your lawn at any time without disturbing your neighbors. When you are done, simple release the knobs and fold the mower up to store. Best of all, this mower comes with the RYOBI 5 Amp Hour battery for extended runtime! This mower is backed by a 5 year warranty.
