An inter-row crop cultivator for use particularly in severe residue conditions such as in minimum tillage conservation applications is disclosed. A leading gauge wheel providing support and soil surface tracking is immediately trailed by two laterally displaced discs which cut away from the row. Aft of the two cutaway discs and directly to the rear of the gauge wheel is a stabilizing and cutting coulter which prevents side to side sway while cutting and reducing residue ahead of a sweep shank which directly trails the cutting coulter. By severing and dividing the residue, the cutting coulter permits the residue to flow over the sweep and around the shank. The shank is adapted to receive an anhydrous ammonia applicator and knife assembly which may be easily and securely mounted to the shank. A plurality of such inter-row crop cultivators may be mounted on a tool bar. A winged ridger/bedder may be either positioned above the soil on the shank or slid down the shank in contact with the soil for forming the loosened soil and residue into parallel ridges over the newly formed rows in preparing a seed bed for later planting. Various selectively adjustable controls are provided for setting gauge wheel height, stabilizing and cutting coulter height, cutaway disc separation and height, the downward pressure applied to the working implements, and implement deflection cushion tension permitting implement deflection upon impact with an obstruction.

A cultivator mounted on an agricultural tool bar pulled by a traction vehicle for working the soil between adjacent crop rows with a plurality of implements and forming the thus worked soil into ridges along said crop rows, said cultivator comprising: a frame rigidly coupled to said tool bar; a gauge wheel for supporting said frame; first and second disc blades coupled to said frame and positioned aft of and laterally with respect to said gauge wheel, each disc blade having a concave work surface for clearing a strip of top soil and trash, mixing them and displacing the mixture laterally between said disc blades; a cutting coulter coupled to said frame and positioned aft of said first and second disc blades and in line with said mixed soil and trash for dividing said trash; a sweep coupled to said frame by means of a shank and positioned aft of and aligned with said cutting coulter for engaging and breaking the soil in undercutting and exposing weed roots in said soil; and a ridger implement mounted to said shank immediately above said sweep for engaging the soil in forming the soil and trash mixture into a pair of parallel ridges located on each side of said shank and positioned along the adjacent crop rows.
