<p>A device for the lateral stabilization of the two liftarms (5) of the an equipment mounting linkage (2) of an agricultural tractor. The liftarms are each provided with a support strut (22) which is connected by means of a pivot bolt (21) to a pivoting pivot arm (15) mounted on a bracket (13) secured to the tractor, the pivot arm (15) interacting with a stop disc (18), which is adjustable manually between a locked position in which a one stop element (19) has the effect of lateral stabilization of an implement connected between the liftarms against movement away from a central position and an unlocked position in which a second stop (20) suspends the lateral stabilization of the implement. With the stop (19) in the locked position an implement, carried by the liftarms is stabilized against movement from the central position in all vertical positions, and with the stop (20) in the unlocking position and the lift arms in a lowered position the implement is not stabilized but in a fully raised position of the lift arms the implement is stabilized against movement away from the central position. Each support strut (22) has an extension (23a) which extends outwards beyond the pivot bolt (21) and the extension (23a) is joined to a link (28:31). The link (28;31) has a first formation in the form of a slot (28a;31a) which engages a second formation in the form of a pin (29,32) secured to the bracket, and with the stop disc (18) pivoted into the unlocked position, at a predetermined raising height of the lift arms (5) and the support struts (22) below the fully raised position , a stop (28b;31b) formed on the link (28;31) comes into contact with the second formation (29,32) thus stabilizing the implement against movements out of the central position.</p> |
