ABSTRACT:
A wear shin for a shank of a tillage tool such as a ripper includes a profile having a narrow leading edge with forwardly concave sides extending rearwardly and outwardly from the leading edge to sides generally aligned with the sides of the shank. Upper and lower ears extend on opposite sides of the upper and lower portions of the shank, and fasteners extend through the ears and shank to releasably secure the shin to the leading edge of the shank. The shin has a narrow profile with width approximately equal to the width of the shank other than at the connecting ears. The narrow leading edge of the shin provides good soil shearing characteristics so the implement slices through the soil, while the forwardly concave sides provide an increasing rate of soil deflection in the rearward direction for better wear, better soil and trash deflection characteristics, and reduced draft requirements.
