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. It is definitely an upgrade for the tractor if it does not already have it as standard. Hydraulic top links are corrosion protected by galvanizing. All hydraulic top links also have a block valve installed for safety. In case of damage to the hydraulic hose, the cylinder of the top link remains in the same position, thus also keeping the tractor attachment in place. The block valve also ensures that the hoses, despite vibrations during driving, are not under pressure, thus not overloading the hydraulic valve on the tractor.
Most common types of hydraulic top links:
- Standard hydraulic top link
(has a welded eye bearing on both sides)
- Automatic hydraulic top link
(has an automatic quick coupling hook for the ball mounted on the piston rod for the tractor attachment)
- Special hydraulic top link
(is an automatic top link, but has a special hook welded on the cylinder instead of an eye bearing, allowing for greater movement of the top link to the left or right)
- Threaded hydraulic top link
(the length of the top link can be extended by the length of the thread)
