摘要： A speed-change transmission apparatus for effecting a speed-changing on an engine drive force with utilizing a continuously variable speed-change device, a plurality of planetary transmission mechanisms and a plurality of clutches is constructed to be capable of effecting the speed-changing operation smoothly, regardless of a centrifugal force generated in the clutches. An output from the continuously variable speed-change device and a drive force from the engine are combined by a planetary transmission section. The drive force from this planetary transmission section is transmitted via a clutch section to an output shaft. First, second, third and fourth clutches of the clutch section are configured to be switched over respectively between an engaged condition and a disengaged condition, as clutch members are engaged with or disengaged from output side rotational members.

摘要： 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.
