    摘要： The invention relates to a haying machine comprising a carrier structure (2) that is provided with at least one working body and can be connected to a tractor (5) by means of a coupling device (6) consisting of a frame (7) provided with two lower hitches (8) and an upper hitch (9), said frame (7) being articulated in relation to the carrier structure (2) by means of a first articulation (23) with an essentially horizontal axis (23a). The invention is characterised in that said machine (1) comprises a suspension device (26) which enables the oscillations to be absorbed and the impacts to be neutralised around the first articulation (23) during transport, and the suspension device (26) is articulated between the coupling device (6) and the carrier structure (2).

    摘要： A drawbar assembly (16;84) is used to connect a farm vehicle, such as a tractor (10), to a towed implement (12). A sleeve (50) is supplied for secure attachment to the frame (18) of the farm vehicle, and dimensioned interiorly thereof to embrace the drawbar (42;86) and allow sliding, reciprocating, co-axial movement of the drawbar (42;86) in the sleeve (50). At least one hydraulic cylinder (54) comprising a casing (66), housing a hydraulically actuable piston (60), and rod (58) assembly therein with the rod (58) extensible beyond the casing (66), is provided. One of the rod and casing is configured for connection to the drawbar (42;86), and the other of the rod and casing for connection to the farm vehicle. A hydraulic system is connected to the hydraulic cylinder (54) to effect adjustment of the rod (58) relative to the casing (66) and thereby position the drawbar (42;86) axially of the sleeve (50), and to pressurize the cylinder (54) in accordance with the damping qualities desired for the load carried by the towed implement (12). In this manner, both position and load changes affecting the drawbar (42;86) may be accommodated in the hydraulic cylinder (54) independent of each other.
