    Abstract: A manually propelled cart for the removal of snow, with dual function as garden cart, comprising: a PVC framework with handles on its upper segment, and a scoop on its lower segment. The framework supported by a rectangular metallic plate adhered to its underside, disposed on top of two large wheels in the middle of its length, with an axle attached to the plate's underside providing the cart a seesaw motion. A pivoted scoop designed as a rectangular bin, with an open forward section and an axle attached to its bottom underside, rotates in a vertical plane. A latch mechanism disposed adjacent the scoop's rearwall, controls its automatic motions and is operated by pulling a cable connected to a handle. Two springs hooked to the scoop's sidewalls and to the supporting plate acting cooperatively with the latch. Two swivel casters underside the plate's forward end, makes the cart steerable.
