Summary:A three-point hitch for an agricultural tractor includes a hydraulically actuatable lifting arm, a vertically pivotable lower link, and a lifting strut arranged between the lifting arm and the lower link. The lifting strut transmits to the lower link a pivoting movement on the lifting arm. The lifting strut includes a first fastening portion articulated to the lifting arm and a second fastening portion articulated to the lower link. The second fastening portion includes first and second fastening segments which encompass the lower link in a fork-shaped manner. A bearing pin disposed between the two fastening segments extends through a slot formed in the lower link. By pivoting the lower link, the bearing pin is displaced inside the slot between a first working position and a second working position. In each position, the bearing pin is secured inside the slot by a blocking arrangement.
