Abstract: A working vehicle, such as a tractor, has a front body supporting an engine E, an intermediate case block having a larger diameter portion 12 accommodating a clutch 9 and a smaller diameter portion 10 housing a continuously-variable hydrostatic transmission and a rear body 6 (Figs 1 and 2) incorporating further gearing driven from the output shaft of the hydrostatic transmission. The front body, intermediate case block and rear body form the body of the vehicle. The further gearing in the rear body provides multiple ranges and include an output to the front wheels, shaft 7c, for four-wheel drive. The gearing in the rear body and the hydrostatic transmission share a common lubricating system. A pedal-operated lever and cam arrangement for controlling the displacement of the pump of the hydrostatic transmission via a servo valve is also described (Figs 13, 14).
