ABSTRACT:
In the agricultural industry, one cultivator wheeled cart cultivator implement has a vertical ripper blade for use in ripper cultivating the soil usually between rows of growing crops. The vertical blade has its front edge sharpened. There is usually a lower point to the blade. Such sharpened front edge portion of the blade which is drawn through the ground, as well as its lowermost point, wear out rapidly, as a result of cultivating in gravelly or hard soil, and have to be replaced often on comparatively small use. Such replacement heretofore required the use of complicated bolt securement of parts, at the front edge and lower ends of the cultivator ripper blade, and the parts to accomplish that replacement are needlessly numerous and complicated and expensive.
