Abstract: Shallow angle furrows between crop beds are reshaped and cleaned in one pass using a tractor-towed implement having angularly even-spaced cutter blades mounted in tiers on drums for rotation about generally vertical axes, perpendicular to the furrow walls on opposing, angularly adjustable decks. The blades of the lower tier are angled to cut into the wall material laterally, parallel to the wall slope, without destroying the root structure of protective sod covering. The cut material is lifted up to the upper tier blades which are offset and lagged so as to eject the cut material up and beyond the furrow wall edges following cutting, in one continuous operation. Plates and pivotal deflectors mounted at the edges of the decks, direct the discharge of cut material. A bell crank and pivotal linkage provides for hydraulically assisted raising and lowering of the apparatus from and into ground contact.
