Tillage implement with on-the-go angle and depth controlled discs

摘要

A tillage implement adapted to be towed by a tractor. The tillage implement having on-the-go angle adjustable disc blades which enables the farmer to vary the amount of crop residue left on the surface of the soil. The implement is comprised of a main frame, a ground wheel assembly operably and pivotally connected to the main frame, a first actuator for pivotally raising and lower the ground wheel assembly with respect to the main frame. The tillage implement further comprising a plurality of disc blade assemblies, the disc blade assemblies arranged as a disc gang. The disc gang being pivotally connected to the main frame such that a second actuator can act to raise and lower the disc gang with respect to the main frame. Each of the disc blade assemblies having first and second disc blades rotatably mounted on disc blade axles fixed to first and second interlocking members. Whereby activation of a third actuator operably connected to the main frame and one of the interlocking members of each disc assembly causes rotation the first and second disc blades such that the angular orientation of the disc blades with respect to the direction of travel of the implement is adjustable while on-the-go to vary the amount of crop residue left on the surface of the soil. The main frame of the tillage implement may further support a plurality of deep tillage shanks. Each of the shanks are positioned rearwardly and longitudinally in line with one of the plurality of disc blade assemblies of the disc gang.
