1. 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 left portion and the front right portion are positioned at an angle of about 18 degrees with respect to a line perpendicular to a centerline of the tilling 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 and the rear left portion following behind the front left portion when the tilling implement is displaced through a field, wherein the rear left portion and the rear right portion are positioned at an angle of about 18 degrees with respect to the line perpendicular to the centerline, and at least a portion of the disc blades of the front row, at least a portion of the disc blades of the rear row, or a combination thereof, 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 respective 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 tilling implement includes no ground engaging tilling tool mounted between the front right portion and the rear right portion, and no ground engaging tilling tool mounted between the front left portion and the rear left portion; and
wherein all ground engaging tilling tools disposed on the tilling implement are configured to rotate in operation.
