An apparatus for breaking up the hardpan subsoil layer of agricultural land has a wheeled frame adapted to connect to a tractor. A roller is rotatably mounted within the frame. A plurality of spike members are attached to the circumferential face of the roller and extend outwardly therefrom beneath the frame for penetrating engagement with the hardpan subsoil layer, to thereby break up the hardpan.

Provided is an earth conditioning system/apparatus which removes/break-ups rock in the ground and has a front drawbar, a ground engaging tool arrangement and a rear rotary device (drum). A ground engaging tool arrangement includes a frame supporting ground engaging tools each mounted at a pivot. Actuators raise/lower the ground engaging tool(s) for desired depth control of the ground engaging tools. The rotary device slotted or ribbed drum acts as a crushing drum rolled over earth that has been broken up by the ground engaging tools. Actuators, provide height adjustment of the ground engaging tools relative to the ground engaging tool support frame and by adjusting the height from the ground of the ground engaging tool arrangement by operating the at least one adjuster acting between the rotary device and the ground engaging tool arrangement.

A tillage apparatus for selective primary tillage and seed bed preparation makes use of a selectively moveable primary tillage shank to provide seasonal, in-field and/or on-the-fly flexibility of tillage operation. The tillage apparatus has a cultivator frame, at least one secondary tillage tool mounted on the frame and a primary tillage shank mounted on the frame, the primary tillage shank selectively moveable between a lowered soil engaging position and a raised disengaged position. In a method of tilling or preparing a seed bed, the tillage apparatus is dragged around a field with the at least one secondary tillage tool engaged with the field when secondary tillage of the field is desired, and the selectively moveable primary tillage shank lowered to be engaged with the field when the field is in need of primary tillage or raised to be disengaged from the field when primary tillage is not desired.

The field cultivating sweep includes a body with wings extending from a center line in opposite directions, and a conditioning element extending downwardly from the wing body. The conditioning element may be a blade extending vertically downwardly along the center line of the body and having a leading edge sloped rearedly from front to back. In alternative embodiments, the conditioning element may have a triangular or rectangular shape or may be in the form of a fluted coulter. The conditioning element acts to till the ground vertically and break up compacted soil as the sweep is drawn along the ground.

A tillage point configured to produce a uniform subsurface soil profile. The tillage point includes a main body having a leading edge, a top surface and a bottom surface. Wing sections extend laterally from the main body.
