Abstract

The trench digger is pulled behind a tractor, and includes a height conrol system so that its tool (5) can be disengaged from buried obstructions. The support system forms a parallelogram linkage, with a oleodynamic actuator cylinder n12) forming a diagonal member controlling the tool lifting action. This support system includes a connecting lever (8) hinged at one end to the arm (4) carrying the tool. a hinged (9) at the other end connects it to an upper arm (10) attached to the tractor member (1). At the junction (7) between the tool carrier arm and the first arm is a further member (3) connection at the other one to the tractor member.
