Top Link Head 150.56.030A (Center Link End) is used in the three-point hitch system of HTZ tractors and is designed to provide a pivoting connection between the top link and mounted agricultural implements, allowing free movement and precise adjustment of the implement position.
The assembly consists of the following main components: Head Body 150.56.158-1A, Ball Joint 77.60.198 / 151.56.301, and two Retaining Rings 150.56.156-1. The head is threaded into Top Link Sleeve 77.60.144A and forms part of the Top Link Assembly 150.56.029.
A version of the assembly is also available with Pin 150.56.034A, supplied with the necessary fastening components: Cotter Pin 150.56.153, Cotter Pin Ring 77.60.195, Top Link Pin 77.60.158, 6×42 Rivet, and Chain 77.60.203-1. This configuration provides a quick and secure connection to mounted implements without the need to source individual components separately.
The integrated ball joint compensates for angular movement of the attached implement, reduces stress on the hitch components, and ensures stable operation under a wide range of working conditions.
The assembly is used in the three-point hitch system of HTZ T-150K, T-151K, T-156, HTZ-17221, HTZ-242K, HTZ-248K, and other HTZ tractor models equipped with the same three-point hitch design.
