摘要
The invention discloses a "three-point" coupling suitable for use both at the front and at the rear of an industrial, agricultural, public works or forestry vehicle, e.g., a tractor. To each bracket of a crossbar attached to a tractor there are pivoted on one side, the rod of a jack and on the other hand firstly a traction rod and secondly one end of a device of adjustable length, the other end of which is pivoted to the associated bar. The two jacks are connected mutually and to a common hydraulic energy source, and the stroke of each piston can be limited in order to determine the final vertical position of the bars by a shutter block carried by one of the jacks and actuated by an adjustable stop fitted on a rod integral with the rod of the jack coming into contact with an actuating push rod of the block.
