FIELD: agricultural engineering.SUBSTANCE: invention relates to a stabiliser for lower and/or upper link of a three-point suspension of an agricultural tractor. Stabiliser comprises a telescope (8) consisting of a tube (5) and a piston (6) held displaceably therein. Tube and piston are elastically connected to each other by a spring (7). Piston (6) is adjustable in length by rotation through a thread (12, 13), and a retaining clip (15) is pivotally mounted on tube (5). In a retention position, retaining clip engages over support (17) of piston (6), and in a release position, telescope (8) is able to move freely. Support (17) is formed by a substantially rotationally symmetric disc, and thus the length of the piston is adjusted in or near the retention position in which a telescope (8) is retained. Retaining clip (15) has two stop surfaces (18) which tightly rest on the support (17) of piston (6) on both sides.EFFECT: enabling adjustment of piston length at or near retention position.9 cl, 3 dwg |
