Upper link 150.56.029-1 central screw (Old model)

The upper link 150.56.029-1 (central screw of the old model) is used in the linkage of HTZ tractors and is designed to adjust the position of the attachment, change the angle of its installation and ensure stable operation of the units during operation.

The design of the central screw includes the following main parts: head 150.56.030A (assembled with pin 150.56.034A), top link coupling 77.60.144A, screw 150.56.347, thrust washer 77.60.147, fork 150.56.043-1, springs 151.56.643 and 151.56.143, pin 77.60.146, fork 150.56.036A, top link pin 77.60.158, as well as other fastening and connecting elements.

Using the traverse 77.60.109, the upper link is installed on the upper splined shaft 151.56.018-2 / 151K.56.018 and ensures the connection of the tractor with mounted agricultural equipment. To fix the implement in the upper transport position, a lock 150.56.035-1 is provided, which prevents spontaneous lowering of the unit during movement.

The old-style central screw is one of the key elements of the three-point hitch system, allowing precise adjustment of the position of the working parts of agricultural machines and ensuring stable operation of the attachment in various operating modes.

It is used in the attachment of tractors HTZ T-150K, T-151K, T-156, HTZ-17221 and other models with a similar design of the attachment system.
