An automatic residual fuel vent device for a carburetor, the device including a fuel supply passage () connecting a fuel tank (TF) and a float chamber (), a negative pressure passage () connecting an intake passage () and a negative pressure operating chamber () of a diaphragm pump (PD), a fuel vent passage () connecting the float chamber () and the fuel tank (TF), a single changeover cock (CO) provided so as to straddle the fuel supply passage () and the negative pressure passage (), a negative pressure surge tank (TS) provided in the negative pressure passage (), and the diaphragm pump (PD), which is connected to the fuel vent passage () and is operated by negative pressure of the negative pressure surge tank (TS), residual fuel of the float chamber () being returned to the fuel tank (TF) by the diaphragm pump (PD) operated by negative pressure from the negative pressure surge tank (TS) in accordance with the changing over of the changeover cock (CO). This enables residual fuel within the float chamber of the carburetor to be reliably returned to the fuel tank by intake negative pressure accumulated in the negative pressure surge tank and, furthermore, residual fuel can be vented by the changing over of a single changeover cock, thus enabling the number of components to be reduced and the device to be provided at a low cost.

A snow removal machine propelled by crawler belts trained around drive wheels and driven wheels is provided. The snow removal machine has a scraper confronting the outer periphery of the driven wheel so as to remove snow adhering to and accumulating on the outer periphery during snow removing operation. It prevents increase in tension of the crawler belt due to the increased diameter of the driven wheel in appearance that might otherwise be caused by snow adhering to the outer periphery.

A working vehicle includes front wheels Wf steered by a steering wheel , and rear wheels Wr driven through a transmission system T incorporating static hydraulic pressure type continuously variable transmissions. A speed change operating device M for controlling speed change of the transmission system T accelerates or decelerates right and left rear wheels Wr at same rotating speed by operation of a change lever , and also generates a difference in rotating speed between the right and left rear wheels Wr by operation of the steering wheel . The steering characteristic on the basis of operation of the steering wheel varies depending on the vehicle speed set by the change lever , so that an appropriate steering characteristic may be obtained if the vehicle speed is changed.

A snow removing machine equipped with a snow removing plate is disclosed. The snow removing plate is mounted to a front portion of a vehicle body which forms part of the snow removing machine. An operating handle having grip portions is mounted to a rear portion of the vehicle body and obliquely extends upward. A battery, an electric motor and a power transmission mechanism are located below a linear line intersecting between an upper end of the snow removing plate and the grip portion. This causes the battery, the electric motor and the power transmission mechanism to be located below a view line of an operator when he looks at the snow removing plate, avoiding the view line from being disturbed to allow the operator to look at the upper end of the snow removing plate in his working attitude for thereby providing ease of operation of the snow removing machine.

A snow removing machine has a vehicle body having a body frame, a snow removing section mounted on a front portion of the body frame for removing snow, an operating handle mounted to a rear portion of the body frame and having a first handle portion and a second handle portion, and a pair of grip portions each mounted on a respective one of the first and second handle portions of the operating handle. A forward and aft drive changeover switch is directly mounted on the first handle portion of the operating handle for changing over a traveling direction of the vehicle body. A height control operation lever is directly mounted on the first handle portion of the operating handle for adjusting a height of the snow removing section. A speed control operation lever is directly mounted on the second handle portion of the operating handle for adjusting a traveling speed of the vehicle body.

A walking-type snow removal machine comprises a snow removing member provided at a front part of a body frame for pushing snow forward, and crawler belts provided on right and left sides of the body frame. The body frame carries thereon an electric motor and a battery. The electric motor drives right and left drive wheels to drive the crawler belts. The electric motor generates little noise as compared with an engine, and contributes to downsizing of the snow removal machine. The battery supplies electrical power to the electric motor.

A working vehicle includes an engine in the rear of a passenger seat, and a working machine vertically movably disposed in the rear of the engine, wherein an upper end of the working machine which is lifted to the highest position is set lower than an upper end of the engine. As a result, a ventilation in the vicinity of the engine is improved and a cooling effect of the engine is enhanced. Also, a maintenance of the engine can be conducted without being interfered by the working machine. Further, with this arrangement, a center of gravity of the working machine is low, thereby enhancing a stability of the working vehicle, and a driver or a passenger of the vehicle can visually check backward much easier.

A hitch structure comprises a support frame adapted to be mounted to a tail portion of a work vehicle, a tube supported crosswise on the support frame and a hitch for connecting a work machine to the work vehicle. The hitch is comprised of an upper jaw plate and a lower jaw plate joined together by a pin in such a manner as to be capable of opening and closing actions, whereby the jaw plates can cooperate to hold the tube on the support frame. The hitch structure thus allows easy mounting and releasing, produces little play, and is free from worries about its parts being lost.
