The Briggs & Stratton(R)EXi875 190cc engine with Mow N' Stow(R)brings commercial power to tough jobs, never requires an oil change, and starts every time. Match your pace to the mower between 1 and 4 MPH, ensuring a seamless experience between you and the machine. The dual cutting blades atomize your grass, while the LaserEdge(R)Eversharp(TM)technology on the primary blade stays sharp longer than traditional blades, self-sharpening as the machine is used. Easily flips upright for smaller storage footprint, blade maintenance, and easier cleaning. The 14 gauge steel deck provides durability, while the 5.5" deep deck design ensures superior mulching performance. | Ariens Razor 21" Dual Blade Reflex Self Propelled Mower
