Abstract: 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.

Abstract: A speed control system for a vehicle having a braking device and a stepless transmission. A change speed member for controlling the stepless transmission is shiftable between a forward drive zone and a backward drive zone across a neutral position. The change speed member is urged to the neutral position, and operatively connected to a change speed pedal and a shift lever. The shift lever is lockable to a selected shift position. Switching may be made between a connection enable state for enabling connection between a first interlocking member connected to the change speed member and a second interlocking member connected to the shift lever, and a connection prohibit state for prohibiting the connection between the first interlocking member and second interlocking member.The connection between the first interlocking member and second interlocking member is canceled with operation of the braking device.

Abstract: A frame structure for connecting working implements to a vehicle body having right and left main frames extending parallel to each other longitudinally of the vehicle body. The main frames are divided into upper front frames and lower rear frames which are interconnected through an intermediate connecting section. The front and rear frames have different heights to lower the center of gravity of the rear section of the vehicle body for promoting stability of vehicle control without impairing the steering function of front wheels. A cross support member is connected to bottom surfaces of the main frames in the region of the intermediate connecting section. This support member has opposite ends thereof extending laterally outwardly of the main frames. Outward extension of the cross support member include connecting elements for working implements. These connecting elements and the front frames are used as supporting connections for connecting working implements such as a front loader and a mower unit.

Abstract: A tractor transmission wherein an engine output is transmitted through a clutch mechanism to a primary change speed mechanism, and a clutch housing and a first transmission case are removably connected to each other. The first transmission case includes a space in a forward portion thereof to accommodate a high speed and low speed switching mechanism and a forward and backward switching mechanism, interchangeable with each other, to be attached to a rear wall of the clutch housing.
