ABSTRACT:
An improved angling snow blade, of the type which pushes snow to the left or right as the supporting vehicle alternates directions across an area to be cleared, has a right (28) and left (29) side panel attached to hinge about the upper edge of the blade, whereby wider swaths can be taken as a result of either side panel blocking the snow from previously cleared areas. A removable bottom panel (31) hingedly attached at its leading edge to the lower leading edge of the side panels enables the improved blade to carry snow from one location and dump it in another and to pull snow away from vertical obstacles, particularly those surrounding corners.
