A foot-assisted snow shovel with a stepbar whereas the user presses down with the foot to initiate the scooping of snow, a guide bar which travels in parallel with the stepbar, a guide channel which the upper pivot points of both stepbar and guide bar are constrained within, a linkage member which holds the stepbar and guide bar parallel throughout their movement, and a scoop clevis fastened to the rear of the snow scoop to which both stepbar and guide bar attach. The parallel configuration of the stepbar and guide bar maintains the scoop in a horizontal orientation during the scooping and the tossing of snow. A protruding feature of the upper end of the guide channels allows the scoop to remain level maintaining its load of snow even as the machine is tilted backward. Rigid uprights with grips provide the framework and the means of handling and control for the user.
