稳定器（10），用于包括第一稳定器构件（12）拖拉机的三点式联接器的下连杆和与所述第一稳定元件（12）是弹簧可移动地连接的第二稳定构件（16），其中，所述第二稳定器构件（16）相对于所述第一稳定元件（12 ）来调整稳定器长度。 甲可枢转地附接到所述第一稳定构件（12）铰接固定用于防止与固定槽（60）接合，所述第二稳定器构件（16）的周边形成的两个稳定器构件（12，16）的旋转支架（58）。 此外，设置了阻挡翼片（62），该阻挡翼片能够枢转到闭合位置以阻止稳定器构件（12,16）之间发生的弹簧运动。 在枢转锁定翼片部分（64）的方向上面对甲安全托架（58）被形成为使得所述固定支架（58），释放用于与所述稳定器（10）配备下连杆，然后从安全槽移除夹持所述第二稳定器构件（16）（60 可以摆动出），当锁定翼片（62）处于所述关闭位置时，在一个模制的固定槽（60）（在第二稳定器构件16）的锁定鼻部（76的周边）形成。

Stabilizer (10) for a lower link of a three-point coupling of a tractor comprising a first stabilizer member (12) and with said first stabilizing member (12) is spring-movably connected second stabilizing member (16), wherein the second stabilizer member (16) relative to the first stabilizing member (12 ) can be rotated to adjust the stabilizer length. A pivotally attached to the first stabilizing member (12) hinged securing bracket (58) for preventing rotation of the two stabilizer members (12, 16) formed with a the periphery of the second stabilizer member (16) securing slot (60) engageable. Furthermore, there is provided a locking flap (62), the spring movement occurring for blocking a between the stabilizer members (12, 16) is pivotable to a closed position. A the safety bracket (58) facing in direction of pivoting locking flap portion (64) is formed such that the securing bracket (58), releasing the second stabilizer member (16) for clamping a with the stabilizer (10) equipped lower link and then removed from the security slot (60 can swing out) when the lock flap (62) is in the closed position, the securing slot (60) molded in one (on the periphery of the second stabilizer member 16) locking nose (76) is formed.
