An agricultural tillage system including a carriage frame assembly, a plurality of tillage elements coupled to the carriage frame assembly, an actuator and a residue reactive system. The actuator is moveably coupled to the tillage elements, and is directly in control of a soil contact depth of the tillage elements. The residue reactive system is in controlling communication with the at least one actuator. The residue reactive system reduces the soil contact depth of the tillage elements when the residue mass on the soil is reduced and/or the slope of the soil is above a predetermined value.

A striptill row unit includes a trash cleaner assembly, a coulter assembly, a knife assembly, a berm disc assembly, and a firming wheel assembly. The berm disc and firming wheel assemblies are independently movable between a raised transport position and a lowered field position. The knife assembly includes downwardly angled wings with leading edges extending substantially perpendicular to the line of travel of the row unit. Up/downforce systems are provided for various assemblies, with an independent actuator for each system. The berm discs are adjustable vertically, laterally, and angularly.

A row crop cultivator row unit (20) includes a frame (22), two front sweeps (24, 26) attached to the frame (22), and a rear sweep (28) that is attached to the frame (22), positioned rearwardly, and between the two front sweeps (24, 26). The two front sweeps (24, 26) are uniform in size, each having a maximum width identical to the other, and the rear sweep (28) has a maximum width that is larger than the front sweep maximum width. In an alternative embodiment, the row crop cultivator row unit includes a frame and a sweep attached to the frame. The attached sweep has a maximum width dimension in the range of 9-36 inches, a maximum height of 25 millimeters, and a sweep pitch angle in the range of 0 to 12. In another alternative embodiment, the row crop cultivator row unit includes a frame and two sweeps attached to the frame. The two sweep have identical dimensions and each has a maximum width dimension in the range of 5-7 inches.

A machine that allows for processing the plant as much as the area where the plant requires and makes the seed bed ready for planting at once and in a single process, for plants planted in the range of 45-70 cm, such as corn, cotton, beet, sunflower, and beans in agricultural areas.
