Abstract
Excavator that comprises a drive unit, an excavator tool and a mounting device for the excavator tool and wherein the mounting device comprises at least two arms that are arranged to be connected to the excavator tool. The excavator comprises resilient portions located in at least two different locations in which the resilient portions are arranged to allow the excavator tool to move in at least one plane relative to the drive unit when the excavator tool is mounted on the mounting device and thereby allow the excavator tool to oscillate in the at least one plane.
