    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 cooling structure for a motor section of a working vehicle with an engine having a vertical output shaft and mounted in an engine hood having an ambient air intake opening defined in an upper surface thereof, and a fan disposed above the engine to draw in cooling air. The cooling air is guided by an air guide cover to flow to a cylinder head and a carburetor attached to a side wall of the cylinder head. The motor section further includes a muffler disposed adjacent and below the carburetor. A muffler cover is disposed between the carburetor and muffler. Part of the air having cooled the carburetor is used to cool an upper surface of the muffler cover. The remaining part of the air having cooled the carburetor is directed under the muffler cover for use in cooling the muffler.

    摘要: A muffler system for a working vehicle, particularly a lawn mower, comprising a main muffler body connected to an exhaust manifold of the engine, and a curved muffler cover covering the main muffler body from below. An exhaust pipe extends from the main muffler body laterally outwardly of the vehicle body, and defines an exhaust outlet for discharging exhaust gas in a direction away from a front wheel and the ground. Cooling air is blown by a cooling fan from the engine into the muffler cover. The muffler cover defines air exhaust openings for directing the cooling air forwardly of the vehicle body.

    摘要: A rotating rate control apparatus for adjusting rotation of an engine of a working vehicle between a minimum rate and a maximum rate. The control apparatus has a first, a second and a third rotating rate adjusting devices. The first rotating rate adjusting device adjusts a basic rotating rate of the engine between the minimum rate and maximum rate. The second rotating rate adjusting device is shiftable between an ON position and an OFF position. The second rotating rate adjusting device is operable, when in the ON position, to set the engine to a predetermined rotating rate between the minimum rate and the maximum rate inclusive. The third rotating rate adjusting device is operable, when the second rotating rate adjusting device is in the OFF position, to adjust the rotating rate of the engine between the basic rotating rate adjusted by the first rotating rate adjusting device and the maximum rate.
