Abstract: An engine-driven generator includes a fuel tank disposed in front of a cooling fan, an air guide space defined between the fuel tank and the cooling fan, an inverter disposed beside a lateral side part of the air guide space, and an air shroud provided between the inverter and the air guide space. The fuel tank is vertically elongated to face a cylinder block of a vertical engine. A storage space having the inverter disposed therein is connected to the air guide space via the air shroud.

Abstract: An engine-driven generator includes an exhaust muffler disposed adjacent to a lateral side of a cylinder block, a fan cover having an air outlet arranged to face the exhaust muffler and the cylinder block, the fan cover being configured to guide cooling air from a cooling fan directly to the air outlet, and an opening area-adjustment member provided on a muffler blow-off port of the air outlet for adjusting an opening area of the muffler blow-off port.

Abstract: A work machine having a loop-shaped operating handle connected to an upper end part of a handle post. The operating handle pivots to positions in the longitudinal direction of the work machine across a longitudinal axis of the handle post as a baseline.

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.

Abstract: A walk-behind self-propelled working machine has a machine body, a working unit mounted on the machine body to perform a working operation, an engine mounted on the machine body to drive the working unit, and a traveling unit mounted on the machine body and drivable to cause the machine body to travel. A control unit controls operations of the working unit and the traveling unit. An operating section is operatable by a human operator to provide signals to the control unit to control operations of the working unit and the traveling unit. A mode selector switch is mounted on the operating section for operation by the human operator to select one working operation mode from among plural alternative working operation modes that are set in advance in the control unit on the basis of a combination of a travel speed of the machine body, a revolving speed of the engine, and an opening of a throttle valve associated with the engine.

Abstract: A snow removing machine has an auger for plowing and collecting snow, a rotatable blower for throwing snow collected by the auger, and a shooter for guiding the snow thrown by the blower so that the snow reaches a selected point. The blower has a central shaft part and blades extending radially outwardly from the shaft part. Each of the blades has one pair of laterally spaced guide walls projecting from a distal end portion thereof in a direction of rotation of the blower. The pair of guide walls for each of the blades extend divergently from each other towards a distal end of the blade.

Abstract: A self-propelled snow remover having a snow-removing implement mounted to the front of a machine body so as to be capable of lifting, lowering, and rolling. The self-propelled snow remover includes an alignment operating member and a return operating member mounted to an operating unit. The alignment operating member is provided for both rolling and vertically moving the snow-removing implement and is disposed towards a left or right side with respect to a widthwise center of the machine body. The return operating member is operated as the snow-removing implement is returned automatically to a predetermined reference position and is disposed in the vicinity of the alignment operating member.

Abstract: A walk-behind self-propelled snow-removing machine includes a snow-removing-unit posture control member disposed on an operating section at one side thereof, a travel ready lever comprised of a deadman's lever mounted on one operation handlebar at the other side of the operating section, and a mode selector switch disposed on the operating section and located forwardly of the travel ready lever for selecting one of plural alternative snow removing operation modes that are set in advance in a control unit on the basis of a travel speed of a machine body, a revolving speed of an engine, and an opening of a throttle valve.

Abstract: A snow removing machine includes a snow blower having a plurality of blades extending radially outwardly from a central shaft part. The blade has one pair of laterally spaced guide walls projecting from a distal end portion thereof in a direction of rotation of the blower. The guide walls extend divergently from each other towards a distal end of the blade.
