Abstract
A deep tillage ripper point includes an aggressive long, narrow leading point portion with a top surface that forms a steep angle of approximately 40-50 degrees with the horizontal. An intermediate portion has a top surface and wings extending at a relatively shallow angle of about 15 degrees relative to the horizontal. A centrally located vertical fin having a width of about half the width of the leading point portion and approximately equal to the width of the ripper shank extends upwardly from the leading point portion rearwardly and above the forward edge and forwardly of the leading edges of the wings. Pre-fracturing action of the fin initiates substantial lateral displacement of the soil prior to the soil contacting the wings. The fin reduces violent vertical eruption of the soil when contacted by the wings and provides improved soil profile.
