Abstract:
1. A tilling implement, comprising: a front row of fluted-concave disc blades coupled to a main frame and having a front right portion and a front left portion symmetrically disposed about a centerline of the implement; a rear row of fluted-concave disc blades coupled to the main frame and having a rear right portion and a rear left portion symmetrically disposed about the centerline of the implement, the rear right portion following behind the front right portion and the rear left portion following the front left portion when the implement is displaced through a field; a plurality of bars extending downwardly from the main frame, wherein each bar is positioned adjacent to a respective fluted-concave disc blade, and each bar is configured to dislodge accumulated soil from the respective fluted-concave disc blade; a pair of wheels, each positioned forward of the main frame along a direction of travel, and proximate to a laterally outward end of the front row of fluted-concave disc blades, wherein the pair of wheels is configured to reduce motion of the main frame perpendicular to the direction of travel caused by the fluted-concave disc blades rotatably engaging the soil; at least one member providing downward pressure, the at least one member attached to the main frame at a position proximate to a rear end of the main frame relative to a position of the fluted-concave disc blades and exerting a downward pressure that reduces and dampens the motion of the main frame caused by the fluted-concave disc blades rotatably engaging the soil; wherein the implement includes no ground engaging tool between the front right portion and the rear right portion, and no ground engaging tool between the front left portion and the rear left portion; and wherein all ground engaging tools disposed on the implement are configured to rotate in operation.
