Shallow disc blade vertical tillage system

A ground working implement comprising:

• a front row of shallow 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 shallow 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 in a right path and the rear left portion following the front left portion in a left path when the implement is displaced through a field;
• 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;
• an adjustable pressure assembly attached to a rear end of the main frame, and a rolling basket assembly connected to the adjustable pressure assembly, the rolling basket assembly extending downward toward the tilling path;
• wherein the rolling basket assembly includes a plurality of rolling baskets, each of the plurality of rolling baskets having a rotational axis and the rotational axes of at least two of the plurality of rolling baskets are not collinear;
• wherein the implement includes no ground engaging tool in the right path between the front right portion and the rear right portion, and no ground engaging tool in the left path between the front left portion and the rear left portion;
• wherein the shallow fluted-concave disc blades have a concavity of between approximately 1.25 and 1.69 inches over an outer diameter of approximately 20 inches, and the concavity of each shallow fluted-concave disc blade is substantially identical;
• and
• wherein the front left portion and the front right portion are positioned at an angle of about 18 degrees with respect to a line perpendicular to the centerline
• wherein all ground engaging tools disposed on the implement are configured to rotate in operation.

A ground working implement comprising:

• a front row of shallow 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, the shallow fluted-concave disc blades of the front right portion and the front left portion being attached generally perpendicularly to respective front tool bars;
• a rear row of shallow 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 shallow fluted-concave disc blades of the rear right portion and the rear left portion being attached generally perpendicularly to respective rear tool bars, the rear right portion following behind the front right portion in a right path and the rear left portion following the front left portion in a left path when the implement is displaced through a field;
• 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;
• wherein the shallow fluted-concave disc blades have a concavity of between approximately 1.25 and 1.69 inches over an outer diameter of approximately 20 inches, and the concavity of each shallow fluted-concave disc blade is substantially identical;
• and
• wherein all ground engaging tools disposed on the implement are configured to rotate in operation.
