In a device for mounting an implement on a tractor wherein a body of the tractor is provided with an upwardly and downwardly movable hitch to which the implement is adapted to releasably mounted, a drive shaft associated to the hitch and drivingly connected to a PTO shaft of the tractor is supported by the hitch and is operable to transmit a power to an input shaft of the implement through shaft coupling means. The hitch is provided with an upper engagement hook opened upwardly and a lower engag...

A power generating and propelling system of a vessel has an electric power generating device (10) installed between an internal combustion engine (2) and a transmission (3). A stator (11) of the generating device (10) is built in a flywheel housing (21a) of the internal combustion engine (2) or a casing (10a) connected to the flywheel housing (21a). A rotary shaft of the generating device (10) is disposed coaxially or eccentrically parallel to a crankshaft (2a) of the internal combustion engine ...
