A lawn mower includes a mower deck supporting a mower belt with cutting elements thereon to produce a cutting action when the belt is driven by a motor to rotate in an endless loop relative to the mower deck. A handle is supported on the mower deck to be movable between different orientations. The mower belt extends along multiple sides of the mower deck which are different in configuration from one another to vary the cutting configuration of the mower as the handle is displaced between different orientations. In a preferred embodiment, the mower deck is triangular in shape and guard members protrude outward from the sides of the deck over the cutting elements with transverse slots therein.
