A sway block (100) of a three-point hitch (AT) of an agricultural implement (AA). The sway block (100) has a supporting frame (1) for supporting a tow hook; and the frame (1) in turn has two substantially parallel right-angle plates (1a, 1b). A respective pair of levers (3, 4) is hinged to each right-angle plate (1a, 1b) by pins (11, 12); and each pair of levers (3, 4) is associated with a respective lock member (2A, 2B) operated from above by an operator by means of an actuating mechanism (MM). The sway block (100) performs the dual function of preventing sway and supporting a tow member.
