    摘要： A small riding lawn mower having a grass cutting unit suspended from a body frame between a front axle and a rear axle, an engine supported by a body frame in a position forwardly of the rear axle with respect to a longitudinal direction of the body frame, a hydrostatic transmission disposed rearwardly of the rear axle, and a driver's seat disposed forwardly of the engine. The body frame includes profile members disposed at opposite sides and extending longitudinally of the mower, and a cross plate interconnecting the profile members. A belt transmission mechanism connecting the hydrostatic transmission to an engine output shaft is surrounded by a plate frame structure formed below the body frame. The plate frame structure defines a further independent chamber for accommodating a muffler of the engine. This chamber has peripheral walls shaped to guide cooling air from the engine to the muffler and laterally outwardly of the mower.

    摘要： An engine speed control system for a working vehicle having an engine, and a propelling transmission and a power takeoff device driven by the engine. Engine speed is adjustable by an accelerator controlled by control signals outputted from a control unit. The control unit is connected to a clutch operation detecting switch for detecting an operative state of a power takeoff clutch for operating a power takeoff device and to a shift condition detecting switch for detecting a shift of the propelling transmission. The control unit outputs a control signal for rotating the engine at an idling speed when the propelling transmission is in neutral and the power takeoff clutch is disengaged, and a control signal for rotating the engine at a high rotating rate when the propelling transmission is in a drive transmitting position or the power takeoff clutch is engaged.

    摘要： A working vehicle comprising an engine mounted on a vehicle frame, a control box mounted on the vehicle frame, and a radiator erected on the vehicle frame between the engine and the control box structure. A dust-proof space is defined by the control box, the radiator and a hinged hood covering the engine. Elastic sealing elements are arranged between opposite lateral sides of the control box and the radiator, and between an upper end of the radiator and the hood. The hood in a closed position presses upon the upper elastic elements to provide an additional support for the radiator and to seal the dust-proof space.

    摘要： A cooling system for a vertical, liquid cooled engine having a first passage for guiding cooling air to a cooling fan disposed above the engine, and a second passage for guiding the cooling air drawn by the cooling fan to flow past the engine and to be exhausted forwardly and downwardly of the engine. The first passage includes an air inlet defined rearwardly of the engine, and is defined by part of an engine hood, a vertical bracket plate erected behind the engine, and a partition extending from the engine hood over an upper surface of the engine. Devices accessory to the engine which are vulnerable to the heat are mounted in a space inside the first passage. The second passage is formed by an air guide cover enveloping the engine and cooling fan and defining an opening in a region opposed to the cooling fan. The air guide cover includes a front portion extending downwardly along the cylinder head. The second passage contains a liquid cooler disposed between an upper surface of the cylinder head and the air guide cover, and a muffler in an exhaust region the second passage. The first and second passages are interconnected through the cooling fan, and define a substantially airtight space from air intake end to exhaust end.

    摘要： A shift adjusting device includes a cam plate and an arm. The cam plate is pivotable and operatively connected to a change speed interlocking mechanism extending between a shift pedal and a belt type stepless change speed device. The arm is also pivotable and operatively connected to a changeover interlocking mechanism extending between a switch lever and a backward/forward drive changeover device. The arm has a pin for engaging a control slot formed in the cam plate. The control slot includes an arcuate forward drive slot portion and an arcuate backward drive slot portion. When the switch lever is in a forward drive position, the pin lies in the forward drive slot portion. The forward drive slot portion allows a full stroke depression of the shift pedal, whereby a forward speed may be selected between minimum speed and maximum speed. When the switch lever is in a backward drive position, the pin lies in the backward drive slot portion. The backward drive slot portion allows only a half stroke depression of the shift pedal, whereby a backward speed may be selected between minimum speed and half the maximum speed.

    摘要翻译： 换档调节装置包括凸轮板和臂。 凸轮板可枢转并且可操作地连接到在换档踏板和带式无级变速装置之间延伸的变速联锁机构。 臂也可枢转并且可操作地连接到在开关杆和向后/向前驱动切换装置之间延伸的转换互锁机构。 臂具有用于接合形成在凸轮板中的控制槽的销。 控制槽包括弧形前进驱动槽部分和弧形向后驱动槽部分。 当开关杆处于正向驱动位置时，该销位于前部驱动槽部分。 前进驱动槽部分允许换档踏板的全行程压下，从而可以在最小速度和最大速度之间选择前进速度。 当开关杆处于向后驱动位置时，该销位于向后的驱动槽部分中。 向后的驱动槽部分仅允许换档踏板的半冲程压下，从而可以在最小速度和最大速度的一半之间选择后退速度。

    摘要： A wheel drive mode changeover apparatus designed to effect a changeover between (a) a two wheel drive mode having only rear wheels driven, (b) a first four wheel drive mode having front wheels and the rear wheels driven at a substantially equal peripheral speed, and (c) a second four wheel drive mode with the front wheels driven at a higher peripheral speed than the rear wheels. The wheel drive mode changeover apparatus includes a control rod for manually switching between the mode (a) and the mode (b) above. By assuming one position this control rod allows the wheel drive mode changeover apparatus to effect the changeover between the mode (b) and the mode (c) in accordance with a traveling condition of a vehicle.
