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.
