Stabilizer for a lower link of a three-point hitch of a tractor, comprising a first stabilizer member and a second stabilizer member connected to the first stabilizer member by a spring mechanism which allows a longitudinal movement between the stabilizer members, wherein the overall length of the stabilizer is adjustable by rotating the stabilizer members against each other. Furthermore, a blocking means is connected to the first stabilizer member, wherein the blocking means can be moved into a closed position in which a longitudinal movement between the stabilizer members is restricted. The first stabilizer member comprises a rotation-symmetric locking collar which engages the blocking means in the closed position such in that a longitudinal movement between the stabilizer members is disabled, wherein a rotation between the stabilizer members is lockable by a safety means, wherein the safety means comprises a spring clip engaging a recess formed in the circumference of the locking collar.
A stabilizer for a lower link of a three-point hitch of a tractor having a first stabilizer member (12) and a second stabilizer member (16) which is resiliently supported with respect to the first stabilizer member (12) along a common longitudinal axis (14), wherein the two stabilizer members (12, 16) are able to be rotated relative to each other in order to adjust the total length of the stabilizer (10) in relation to the common longitudinal axis (14), and wherein there is provided a locking means (38) which is connected to the first stabilizer member (12) and which can be moved into a predetermined locking position in order to limit a resilient movement which occurs between the two stabilizer members (12, 16), characterized in that the first stabilizer member (12) has a locking collar (50) which is constructed in a rotationally symmetrical manner with respect to the common longitudinal axis (14) and which, when the locking means (38) is located in the predetermined locking position, engages in a recess (48) which is arranged in the locking means (38) in such a manner that a deflection and rebound movement which occurs between the two stabilizer members (12, 16) is prevented, wherein the second stabilizer member (16) can be secured with respect to the first stabilizer member (12) by way of a securing means (76), wherein the securing means (76) comprises a curved resilient member (78) which engages in a recess (80) which is provided in the periphery of the locking collar (50).
