A cutter device is provided for being attached to an end of a movable working arm of a self-propelled vehicle for clearing and mulching trees. The cutter device includes a rotatably mounted drum with a plurality of spaced cutter teeth attached to an exterior of the drum for engaging and grinding the trees. A shield covers a portion of the drum and contains the deflection of wood debris outwardly from the drum during operation. The shield has an interior wall spaced apart from the cutter teeth and cooperating with the rotating drum to define a debris flow path through the device. At least one deflector plate is attached to the interior wall of the shield. The deflector plate extends inwardly into the debris flow path in a direction towards the cutter teeth of the drum. The interior wall of the shield and the deflector plate collectively form a mulch zone in an area between the cutter teeth and the shield and upstream of the deflector plate for slowing the movement of debris along the flow path, and deflecting the debris back into contact with the cutter teeth for being further cut and reduced in size.
