The RYOBI 40V HP Brushless 20" Self-Propelled Multi-Blade Mower delivers more power than a 150cc gas mower, making it a true gas replacement. The included 40V 8Ah battery provides up to 50 minutes of runtime on a single charge, ideal for up to 1/2 acre. Experience the industry’s best 3-in-1 cutting performance with the CROSS CUT™ Multi-Blade System. This allows for less clumping when mulching, further & more even dispersal when side discharging, and when bagging the fine clippings fill from back to front to maximize space for less bag changes. El motor sin escobillas y su electrónica de vanguardia automáticamente reaccionan a las condiciones del corte: incrementan la velocidad de la hoja para eliminar los atascamientos y aumentan la potencia durante los cortes más duros. Equipped with self-propelled rear wheel drive, this mower ensures an effortless, efficient mowing experience. When the job is done, the handles easily collapse for compact, vertical storage. Y lo mejor de todo, forma parte del sistema RYOBI de 40 V, donde cualquier batería de 40 V funciona con cualquier producto de 40 V.
