Hydraulic top link
(eng. top link or third point, ger. hydraulischer oberlenker) is basically a standard double-acting hydraulic cylinder with welded connections for mounting between the tractor and the tractor attachment. Hydraulic top links are corrosion protected by galvanizing. All hydraulic top links also have a block valve installed, which serves for safety (in case of damage to the hydraulic hose, the top link cylinder remains in the same place, consequently 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.
Here we encounter the three most common types:
- standard top link
(has a welded eye bearing on both sides)
- automatic top link
(has an automatic quick-release hook for the ball mounted on the piston rod for the tractor attachment)
- special top link
(is basically an automatic top link, but has a special hook welded to the cylinder instead of an eye bearing, allowing for greater movement of the top link to the left or right),
