  • Patent number: 7997016
    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.

  • Patent number: 7343994
    Abstract: A working machine has a machine body, a working unit attached to the machine body, an internal combustion engine for driving the working unit, a traveling unit mounted on the machine body 11 for displacing the working unit over a ground surface to perform a work operation on the ground surface, and an electric motor for driving the traveling unit. A battery supplies electric power to the electric motor in a battery mode of the working machine to thereby drive the electric motor. A battery mode switch switches between an ON position in which the working machine is in the battery mode and an OFF position in which the working machine is not in the battery mode. A power generator is driven by the internal combustion engine to supply electric power to the battery and to the electric motor.
