Abstract
A rotary ditcher attachment is selectively mounted onto the bottom of an excavator implement. The rotary ditcher attachment has an attachment frame including a mounting bracket for releasable mounting onto a tool mount on the boom of the excavator implement. A rotary disc assembly on the attachment frame includes a rotor supported for rotation relative to the attachment frame about a disc axis, and a plurality of blades supported on the rotor for cutting into the ground as the rotor is rotated. A drive motor for driving rotation of the rotor relative to the attachment frame is supported on the attachment frame so as to be releasable from the boom together with the attachment frame.
