摘要： In a working vehicle such as an agricultural tractor, a front wheel change speed device for transmitting drive to front wheels includes an equal speed clutch for driving the front wheels substantially at the same speed as rear wheels, and an accelerating clutch for driving the front wheels substantially at a higher speed than the rear wheels. In the front wheel change speed device of this invention, the equal speed clutch and accelerating clutch are arranged coaxially. The front wheel change speed device further includes a shift member axially shiftable for selectively operating the equal speed clutch and accelerating clutch, and an actuator for axially shifting the shift member.

摘要： A change speed apparatus for a working vehicle includes a first shaft for receiving driving torque from an engine, a second shaft for transmitting the driving torque to a rear wheel differential, a change speed mechanism for changing speed of the driving torque received from the first shaft and transmits the driving torque to the second shaft, and a shift lever for selectively switching the change speed mechanism. The change speed mechanism has a high forward speed stage, a low forward speed stage, a backward drive stage, and a neutral stage. The shift lever is movable along a transverse control path for the neutral stage, a first longitudinal control path for the high forward speed stage, a second longitudinal control path for the low forward speed stage, and a third longitudinal control path for the backward drive stage.

摘要： A turn control system for a four wheel drive vehicle which includes an accelerating transmission for driving the right and left steerable wheels at a greater average velocity than the right and left non-steerable wheels. A steering device and a switching device are interlocked such that a change speed device is operable in the accelerating transmission when the steerable wheels are steered in excess of a predetermined angle. An inner one of the steerable wheels with respect to a turning circle has a maximum steering angle .beta.1 which is set to form the following expression:secant .beta.1>Kwhere K is a ratio of the greater average peripheral velocity of the right and left steerable wheels when driven by the accelerating transmission with respect to the peripheral velocity of the right and left non-steerable wheels.

摘要： An instrument panel to be mounted at a driver's section of a working vehicle such as a tractor is secured to a frame member which extends upwardly from a main frame. A panel cover for covering a steering-wheel peripheral section of the machine includes an opening through which the instrument panel is exposed to the outside and this panel cover is detachably attached to the frame member.
