The first shredder head is movable between elevated and lowered positions for clearing brush and trees in a first band. A second shredder head is operatively connected to the second side of the frame. The second shredder head is parallel to the first shredder head and is spaced apart therefrom. The second shredder head is movable between elevated and lowered positions for clearing brush and trees in a second band spaced apart from the first band. Thereby, the tractor leaves between the first and second bands a residual band of brush and trees.
