ABSTRACT:
The invention is a hand operated snow removal device adjustable for use on both pitched or flat surfaces. It consists of a scooping element supported on an adjustable guide spacer attached to the scooping element adapted to support the scooping element above the snow surface. A handle extends through the scooping element and is adjustably clamped for a flat roof use or a pitched roof use. It is hand operated by a forward and backward motion of the handle which picks up and discharges snow to the side as it is being operated.
