RYOBI redefines cordless lawn mowers with the second generation 20 in. 40-Volt Brushless Mower. Featuring gas-like power, this mower has an intelligent brushless motor with load-sensing technology, allowing it to detect and deliver the power needed to maintain an optimal cutting speed. This means the mower will not get bogged down in overgrown patches of grass and, when additional power is not needed, increases run time by saving the battery. The RYOBI Brushless Mower has a large 20 in. cutting deck, and with its mulching or bagging option, you can get the job done quickly and just the way you like. With its push-button start and 7-position single point height adjustment, you’re ready to begin in seconds without having to mess with gas and oil. For easy and compact storage, the telescoping handle has quick-release knobs and the mower is designed to be stored vertically. If you have close neighbors or prefer mowing in the cooler evening hours, this whisper-quiet design with high-intensity LED headlights is the perfect solution. This mower is equipped with a 5.0 Ah 40-Volt Lithium-Ion high capacity battery for extended run time. The included battery and charger are compatible with any RYOBI 40-Volt tools.
