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 certainly 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 top link cylinder remains in the same position, and consequently, so does the tractor attachment. The block valve also serves to ensure that the hoses, despite vibrations during driving, are not under pressure, thus preventing the hydraulic valve on the tractor from being overloaded.
The 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
(this is an automatic top link, which 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)
