A stabilizer for a lower link of a three-point hitch of a tractor, includes a first stabilizer element and a second stabilizer element, which is supported so it can move with spring action relative to the first stabilizer element along a common longitudinal axis. A first limiting member is connected with the first stabilizer element, which in a closed position forms a first stop which interacts with the second stabilizer element to limit compression movement between the two stabilizer elements. A second limiting member between the two stabilizer elements forms a second stop to limit the compression movement relative to a corresponding end stop of the stabilizer when the first limiting member is brought into an opened position.
