ABSTRACT:
A self-propelled snow remover has a machine body, a snow-removing implement mounted to a front part of the machine body for undergoing rolling and vertical movement relative to the machine body, and an operating unit mounted to a rear part of the machine body. An alignment operating member is mounted to the operating unit for rolling and vertically moving the snow-removing implement. The alignment operating member is disposed on one of opposite sides of a widthwise central line of the machine body. A return operating member is mounted to the operating unit for automatically returning the snow-removing implement to a predetermined reference position. The return operating member is disposed proximate to the alignment operating member at a position closer to the widthwise central line of the machine body than the alignment operating member and further towards the rear part of the machine body than the alignment operating member.
