    Abstract: A work vehicle coordinating system includes a main vehicle position detection module for detecting a position of a main work vehicle (1P), a sub vehicle position detection module for detecting a position of a sub work vehicle (1C), a central work land path calculation section for calculating a central work land traveling path to be used by the sub work vehicle (1C) in an unmanned steered work traveling in a central work land (CL), a first steering control section for unmanned-steering the sub work vehicle (1C) ahead of the main work vehicle based on the position of the sub work vehicle detected by the sub vehicle position detection module and the central work land traveling path, a headland path calculation section for calculating a headland traveling path to be used for unmanned steered traveling of the sub work vehicle (1C) based on a traveling path of the main work vehicle (1P) in a headland (HL), and a second steering control section for unmanned-steering the sub work vehicle (1C) to follow the main work vehicle (1P) based on the detected sub work vehicle position and the headland traveling path.

    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).

    Abstract: A frameless type working vehicle includes an intermediate vehicle body 5 acting as a body forming member for interconnecting a front vehicle body 3 and a rear vehicle body 4. The intermediate vehicle body is formed of a case block 10 housing a hydrostatic stepless transmission (HST) 20. The case block 10 includes, formed integral with one another, a small diameter portion 11 connected to the rear vehicle body 4 and providing case walls for a pump P and a motor M of HST 20, a large diameter portion 12 connected to the front vehicle body 3 and having an upper edge at a higher level than an upper surface of the small diameter portion 11, and a transitional portion 12A disposed between the small diameter portion 11 and the large diameter portion 12. The large diameter portion 12 defines an accommodating space S1 for a main clutch 9 that receives drive from an engine E.
