For yards up to 1 acre, a self-propelled mower cuts the grass and powers a drivetrain that propels the mower forward, making it easier and requiring less effort. The single speed rear-wheel drive mower delivers the extra traction needed to take on any type of terrain, even hills. With three-in-one discharge capabilities you can mulch, bag, and discharge without messy clumps. 45.00 H x 27.00 W x 21.00 D.
