The accessory for an earthworking machine for dredging ditches or streams comprises an arm (22) extending from an adaptor (21) and carrying a cleaning tool (24) on its free end. The adaptor is pivotally attached at one point (25) to the existing jointed arm (13) and pivoted at a second point (26) to an actuating ram (18).
