Patent ID: 8511398

Claim:
A tilling implement, comprising: a front row of disc blades coupled to a main frame and having a front right portion and a front left portion, wherein the front right portion extends across a right tilling path on a right side of a centerline of the implement, and the front left portion extends across a left tilling path on a left side of the centerline of the implement; a rear row of disc blades coupled to the main frame and having a rear right portion and a rear left portion, the rear right portion following behind the front right portion in the right tilling path and the rear left portion following behind the front left portion in the left tilling path when the implement is displaced through a field, wherein at least a portion of the disc blades comprises fluted-concave disc blades; 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 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 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 each ground engaging tool in the right tilling path and each ground engaging tool in the left tilling path is configured to rotate in operation.
