Abstract

The three-point coupling is mounted on a tractor (1) and comprises a pair of support arms (2), a pair of link arms secured thereto, and a lifting cylinder to operate the support arms. On the support arms (2) is pivotally mounted a crane stand (4), having support legs 5, and which is secured to the tractor (1) by means of a pivotable stay (6). A traction piston- and-cylinder unit (8) is secured to the crane stand (4) by its cylinder end. From the piston rod of the unit extend two chains (9) which are secured to respective ones of attachment points between the support arms (2) of the three-point coupling. <IMAGE>
