A support for supporting an implement (42) from a terrestrial vehicle (1) is disclosed. The support comprises a primary support member (4) for mounting on the vehicle (1) and a secondary support member (20) to which the implement (42) is mounted. The secondary support member (20) is joined to the primary support member (4) by a pair of substantially equal length substantially parallel arms (24, 26) in an articulated parallelogram arrangement. The parallel arms (24, 26) are pivotally attached to each of the primary (4) and secondary (20) support members at four pivotal connections (32, 34, 38, 40) having mutually parallel and spaced apart pivot axes, which in use are transverse to the direction of vehicle (1) travel. The parallel arms (24, 26) are each pivotable relative to the primary support member (4) through an angular range in which the arms (24, 26) depend downwardly and rearwardly from the primary support member (4). The secondary support member (20) has a lower end (22) which is adapted for contacting a ground surface over which the support is moved. The primary support member (4) is supported on an adjustable frame member (2) that in use can raise and lower the primary support member (4) relative to the vehicle (1).
