摘要： A length adjustable lifting strut (1) for a hitch linkage of a tractor has two connection elements (11, 12) for connecting the lifting strut (1) to components (43, 44) of the hitch linkage. A fine adjustment mechanism 17 is provided on the lifting strut (1) to finely adjust the length of the lifting strut 1. A quick adjustment mechanism (21) is provided to adjust the lifting strut (1) length and is retainable in at least two discrete positions.

摘要： A coupling hook 5 for a lower steering arm 3 of a three-point attaching device of a tractor has a hook member 6 with a locking catch 7 which is spring-loaded in the direction of the locking position. The locking catch 7 is arranged in a recess 12 of the hook member 6 and extends through an aperture 13 into the bearing recess 10 to receive a bearing ball 11. For the purpose of supporting and guiding the locking catch 7, the hook member 6 is provided with a first stop face 14 and a second supporting stop 15, arranged at a distance therefrom and offset towards the rear. In the locking position, the locking catch 7 is supported on the hook member 6 by means of a first supporting face 19, a second supporting face 21 and a blocking face 22. The assembly is designed in such a way that the second supporting face 21 and the blocking face 22 form part of a recess in the locking catch 7 and that contact between the blocking face 22 and the supporting stop 15 takes place beneath an imaginary connecting line 27 between the contact point between the locking face 25 of the locking catch 7 and the outer face 26 of the bearing ball 11, on the one hand, and the center 29 of the convex supporting stop 15, on the other hand. In this way, an improved locking effect is ensured.

摘要： A coupling hook (5) for the lower steering arms (3) of a three-point attaching device of a tractor has a hook body (6) with a locking pawl (7). The pawl (7) is spring-loaded in the direction of the locking position. The locking pawl (7) is arranged in a recess (12) of the hook body (6) and projects through an aperture (13) into a bearing recess (10), which receives a bearing ball (11). For the purpose of supporting and guiding the locking pawl (7), the hook body (6) includes a first stop face (14), a second supporting stop (15) offset backwardly at a distance therefrom and a locking stop (16). In the locking position, the locking pawl (7) is supported on the looking stop (16) via a first supporting face (19), a second supporting face (21) and a locking face (22). The design is such that the contact between the locking face (22) and the locking stop (16) takes place below an imaginary connecting line (27) which is between the point of contact of the locking face (25) of the locking pawl (7) with the outer face (26) of the bearing ball (11), on the one hand, and the center (29) of the convex locking stop (16) on the other hand. An improved locking affect is ensured.

摘要： A coupling hook (5) for a lower steering arm of a tractor (1) has a hook body (7) with a bearing recess (8) to receive a bearing ball (6) of a to be coupled implement. The hook body has a recess (9), a through hole (10) between the recess (9) and the bearing recess (8), an exiting aperture (11) connecting to the recess (9) and open to the exterior, and a first support element (12) and a second support element (13). The second support element (13) extends through the exiting aperture (11) and separates the exiting aperture into a first opening portion (14) and a second opening portion (15). A locking pawl (17) is movable between a locking position, where it projects into the bearing recess (8), and a detaching position, where it is retracted into the through hole (10). An adjustment element (30) engages the locking pawl (17) and acts on it to take up the locking position. An opening lever (26) is pivotably connected to the locking pawl (17) and is movably supported on the second support element (13). The opening lever (26) has a locking lug (28) to secure the opening lever in a holding position where the locking lug (28) is retainingly engaged in the second opening portion (15).
