The support at the front of an implement that connects to the back of a tractor.

Cf. Pflugturm.

"The pivoting headstock unlocks while at work to closely follow the path of the tractor when turning, without damage to the windrow. When raised for transport, the headstock automatically centers and locks for added safety".

"The headstock angle can be adjusted and with three top linkage positions optimum adaptation to any tractor is guaranteed."

"A damping cylinder in the plough headstock reduces tractor strain and protects both tractor and implement components at headlands and during road transport."
"Der Dämpfungszylinder im Pflugturm verringert die Belastung des Traktors und schont die Bauteile des Gespanns am Vorgewende und auf der Straße."
