An upper link for a three-point power lift of an agricultural tractor including a cylindrical connecting sleeve, a first fastening element rotated into a first open end of the cylindrical connecting sleeve and configured to be attached to the agricultural tractor, a second fastening element rotated into a second open end of the cylindrical connecting sleeve and configured to produce a releasable connection to an attachment, and a retaining bar attached to the first fastening element. The retaining bar includes a bar portion having a locking region for receiving a retaining catch and runs spaced apart along the cylindrical connecting sleeve. The retaining bar includes a support element encompassing the cylindrical connecting sleeve such that the connecting sleeve is rotationally displaceable, and the length of the upper link is varied by rotating the cylindrical connecting sleeve.

A bearing arrangement is provided for a side stabilizer of a rear power lift for an agricultural utility vehicle. The arrangement includes a movable bearing and a bearing bracket for the bearing. The bearing bracket is disposable in an installed operating position to achieve a mechanical coupling of the bearing bracket with the rear power lift. An axle housing includes a central longitudinal axis for a rear axle of the utility vehicle. The bearing bracket has a bearing point for the movable bearing of the side stabilizer and is connected to the axle housing by a clamping force. The clamping force is oriented parallel to a traction force acting on the bearing point in the installed operating position.

A mounting bracket for mounting a front three-point hitch on a tractor includes a linking part for articulated mounting of the front three-point hitch, a connecting part for coupling the linking part to a support structure of the tractor, and a first contact region defined on the linking part and a second contact region defined on the connecting part. The first contact region interacts with the second contact region for coupling the linking part to the connecting part. The first contact region and the second contact region are separably clamped to one another in a coupling position. The linking part is selectively disposable in one of a plurality of coupling positions relative to the connecting part.

A power lift for an agricultural tractor includes a supporting structure configured to be mounted on the agricultural tractor. A left lower link, a right lower link, and an upper link are coupled in a pivotally movable manner, wherein the left and the right lower links and the upper link include coupling elements for attachment of an agricultural attachment. The left and the right lower links are rotatably coupled to one another via a lifting shaft, the lifting shaft being aligned with a lower link pivot axis. The left and the right lower links are pivotable by an actuating element which runs between at least one of the lower links and a support point of the supporting structure jointly about the lower link pivot axis in relation to the supporting structure.

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.

Stabilizer for a lower link of a three-point hitch

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.

Stabilizer for a lower link of a three-point hitch of a tractor

Stabilizer for a lower draft link of a three-point hitch of a tractor, the stabilizer comprising a first stabilizer member and a second stabilizer member which is movably connected to the first stabilizer member by a spring-loaded centering mechanism, wherein the second stabilizer member can be rotated with regard to the first stabilizer member to modify the overall length of the stabilizer. A locking bracket is pivotally connected to the first stabilizer member for blocking a rotation between the stabilizer members by engaging the locking bracket with a blocking groove formed in a circumference of the second stabilizer member. Furthermore, a locking cover is provided for disabling a movement between the stabilizer members in a closed position. A section of the locking cover is faced to the locking bracket, wherein the section is formed such in that the locking bracket can be removed from the blocking groove for releasing a rotation of the second stabilizer member even in the closed position of the locking cover.

A towing mechanism includes a pair of brackets for receiving a drawbar therebetween, and a locking device. A towing bolt is received by locating bores in the brackets. The locking device includes a locking pin which is axially slidable in a pin bore in a component. The locking device is mounted on the upper bracket so that, in a locked condition, the locking pin projects out of the bore and prevents axial movement of the towing bolt. A blocking member at least partially covers the pin bore and prevents the extraneous material from contacting the locking pin, in order to reduce the likelihood of an unintentional release of the towing bolt.

Towing mechanism

A securing bolt device is inserted into a bore of a subassembly body. The device has a bolt and a spring element. The bolt has a shank which is insertable into the bore. A radial transverse bore extends through an end portion of the shank opposite to the insertable portion of the shank, and the shank has a blind bore in an axially directed end face. The spring element includes a loop, a first end of which is insertable into the transverse bore and a second end which is insertable into the end face bore. The loop forms a crossmember which extends across the shank of the bolt, and pressed against the bolt element by the spring force of the spring element. The locking device includes a subassembly body having a bore in which the bolt is axially movable. In a locked state a free end of the shank extends out of the bore and locks the securing bolt.
