Agricultural tilling implements are described. In some embodiments the implements are adapted for deep tilling of soil between growing row crops, in which embodiments a horizontal shield member is detachable secured to a depending shank. The front edge of the shield is sloped upwardly. The shield prevents soil from being thrown upwardly and onto the top of growing row crops during tilling between the rows. The shield also guides loosened soil around the base of growing crops in the rows. In one embodiment the implement includes downwardly depending plate members beneath the shield to urge soil outwardly from the shank to the row crops to form a hill in each row without covering the crops. In another embodiment a V-shaped ditcher is disposed beneath the shield for forming a trench or ditch between adjacent rows of crops. Both embodiments include adjustable wing members or deflectors at the trailing edge of each plate member to control the amount of loosened soil which is urged outwardly to the row crops.
