General description:

The hydraulic lifting top link (eng. top side link or side third point, ger. seitliche hubstrebenverstellung) is essentially a standard double-acting hydraulic cylinder with welded connections for mounting on tractor hydraulic arms. It serves for individual adjustment of the height of the arms of the hydraulic three-point system. It can also serve for additional reinforcement of the arms or increasing load capacity.
All hydraulic lifting top links are also equipped with a block valve, which serves for safety (in case of hydraulic hose damage, the cylinder of the top link remains in the same position, thus also the tractor attachment). The block valve also ensures that the hoses are not under pressure and thus do not load the hydraulic valve on the tractor during driving due to vibrations.
