Abstract: A dual cutter head mower attachment particularly suited for mowing beneath guard rails, and fences which can be operated at either lateral side of a support vehicle. Support arms for the cutter heads are pivotally connected to the lower ends of upstanding legs of a U shaped support frame by releasable connections facilitating repositioning of the support arms when the mower attachment is to be operated at the opposite lateral side of the support vehicle.

Abstract: A dual cutter head, self contained mower (30, 200) is provided for cutting vegetation beneath and on opposite sides of guard rails or cable barriers, and on opposite sides of rows of small trees, hedges, walls or fences. The cutter heads (52, 53 and 252, 253) are staggered to cut overlapping swathes and are adjustably biased to permit the cutter heads to move laterally away from one another when an obstacle is encountered. The outer cutter head (53, 253) can be swung to an overhead position to avoid road signs, poles or the like. The mower can be front or rear mounted and can be reversed to cut at either side of the supporting vehicle. A spray system (323) applies herbicides or other liquids to the area being mowed.

Abstract: A fork lift truck attachment having side shiftable forks which can be adjusted for side loading and which can be tilted fore and aft laterally.

Abstract: An excavating device for scraping away the high shoulder material on the road sides. The device includes a rotating drum on which are permanently attached tooth-supports arranged in a helix. On the supports are fastened spikes and teeth, different types for different terrain. Scraped earthen material can be dispersed or windrowed and by arranging the supports on opposite helixes or by reversing rotation, the material can be dispersed or windrowed right or left of the rotating drum. A frame is employed to support the rotating drum, and the drum can be articulated to various working positions by hydraulic cylinders. A retractable hood is located above the rotor and movable deflectors are provided for material flow control. Tracer wheels facilitate control of the desirable digging depth.
