摘要： A working vehicle is provided for improving safety and work efficiency by changing a travel speed limit appropriately depending on forms and conditions of work. The working vehicle is driven with an engine, and a working machine such as a working pump is mounted on the vehicle. Fuel supplied to the engine is regulated by an injector. Travel speeds of the working vehicle are detected with a vehicle speed sensor. A control unit is provided with a high speed travel mode which limits vehicle speed at or below a predetermined high speed limit and a low speed travel mode which limits vehicle speed at or below a low speed limit which is set below the high speed limit. In this way, either the high speed travel mode or the low speed travel mode is set according to a changeover signal from a travel mode changeover switch.

摘要： A working vehicle for work such as a turf grass management is provided, which has an improved climb-up performance and an improved engine-break force at a stage of climbing down a slope. The working vehicle mounts a working machine driven by an engine and also a continuously variable transmission thereon, and has a climb-up or climb-down mode Df which sets a transmission ratio of the continuously variable transmission at a maximum value during travel of a slope. The climb-up or climb-down mode Df is selected by an operation of a shift lever or automatically detected by climb-up or climb-down detectors. When the mode Df is set, a pulley ratio of the continuously variable transmission is controlled so as to have the maximum transmission ratio based on a command signal of a control unit.

摘要： A steering system and method of a mowing vehicle comprise Left and right rear wheels rotating about a king pin for steering the vehicle, an Ackermann steering mechanism for steering these left and right rear wheels and a rear axle housing swingably connected with the vehicle about a yawing axis in a horizontal plane by use of a hydraulic cylinder. When the vehicle makes a U-turn for example to the right during the mowing work, the rear axle housing is fully swung to the left in the horizontal plane by a specified angle and fixed therein while the left and right rear wheels are held at the neutral position. After the rear axle housing is fixed at that angle, the left and right rear wheels are rotated about the king pin to the left and then the vehicle makes a U-turn to the right. When the vehicle finishes to turn, the left and right rear wheels are rotated about the king pin to the right until the neutral position and then the rear axle housing is swung in the horizontal plane back to the right until the neutral position. When the vehicle makes a U-turn to the left, the same operations are carried out. Since the rear wheels are steered after the rear axle housing is swung in the horizontal plane and fixed, the vehicle can make a U-turn with a minimal turning radius, retaining the Ackermann steering condition and the lawn can be prevented from being damaged by the wheels.
摘要翻译：割草车辆的转向系统和方法包括围绕用于转向车辆的主销旋转的左右后轮，用于转向这些左右后轮的Ackermann转向机构和与车辆围绕偏转摆动地连接的后桥壳体通过使用液压缸在水平面上。当车辆在割草作业期间例如右转时，后桥壳体在水平面上完全摆动指定角度并固定在左侧，而左后轮和右后轮保持在中立位置在后桥壳体以该角度固定之后，左右后轮围绕主销向左旋转，然后车辆向右转。当车辆转弯时，左右后轮围绕主销向右旋转，直到中立位置，然后后桥壳体在水平面上向右摆动回到中间位置。当车辆向左转时，进行相同的操作。由于在后桥壳体在水平面上摆动并固定后轮被转向后，车辆可以以最小的转弯半径进行U形转弯，保持了Ackermann的转向状态，并且可以防止草坪被损坏车轮。

摘要： In a carburetor of a motor vehicle engine having an accelerating pump for supplying additional fuel when an accelerator pedal is depressed to a large extent, the accelerator pedal is connected to a slider which is connected through an accelerating pump cable to a swing arm for actuating the accelerating pump via a link and a lever. The slider is connected also to a throttle lever through a throttle cable. The throttle lever is coupled to a throttle shaft of a throttle valve by means of a torsion spring. When the accelerator pedal is depressed, the throttle cable and the accelerating pump cable are pulled, and the control lever is turned to rotate the throttle shaft by way of the spring in a direction toward an open position of the throttling valve so that the engine is accelerated, while the accelerating fuel pump is operated through the swing arm, the link and the lever so that an increased amount of fuel is supplied by the pump. Since the throttle valve and the accelerating pump are operated separately by way of the respective cables, the throttle shaft can be rotated with a small torque and the speed control can be carried out exactly without delay.

摘要： A working vehicle is provided which can be smoothly started with a large driving force, and uniformly conducts a various types of works even if a travel speed varies. A working machine such as a working pump, which is also driven by an engine for driving the vehicle, is mounted on the working vehicle. The power is transmitted from a crank shaft of the engine to wheels through a torque converter provided with a lock-up clutch and an automatic transmission. The crank shaft is also connected to a driving unit for driving the working pump through gears. A transmission ratio of the automatic transmission is set to a predetermined value corresponding with work modes J1-J6. In such a way, the work modes J1-J6 are set according to characteristics of the work, in which there exists a predetermined relationship between a work amount and a vehicle speed. Therefore, fertilizer, sand, and chemicals can be appropriately and uniformly spread through a changeover of the modes.

摘要： A turn assisting mechanism assists a turning motion of a vehicle, such as a lawn mowing vehicle, so that the vehicle may not damage the ground (lawn grass, crops, etc.) when the vehicle makes a U-turn. The turn assisting mechanism is disposed near a wheel of the vehicle nearest to the center of turning of the vehicle about which the vehicle makes a U-turn. The turn assisting mechanism stretches out the rod of a hydraulic cylinder actuator to set a ground contact unit on the ground and lifts up the wheel nearest to the center of turning of the vehicle. When the vehicle makes a U-turn, the hydraulic cylinder actuator sets the ground contact unit on the ground so that the axis of turning of the ground contact unit passes the center of turning of the vehicle, and lifts up the corresponding wheel from the ground. The vehicle makes a U-turn on the ground contact unit without damaging the ground.
