ABSTRACT:
A cultivating machine has a structure arranged to be mounted on ground engaging wheels for movement in a line of travel. At least one tool support is mounted on the structure so as to be moveable with respect thereto, and a drive is also mounted on the structure for driving the tool support. The tool support has a body having two end portions, the first end portion being driven in use in a circular path by the drive. The second end portion is connected to the structure through a link arm pivotably attached to the tool support and to a swing arm, which in turn is pivotably attached to the structure, the swing arm being biased toward a median position and the second end of the tool support carrying at least one cultivating tool.
