ABSTRACT:
A combined scarifier and branch slashing and crushing implement is disclosed. The implement comprises a rectangular frame, a cylindrical roller rotatably mounted in the frame and extending longitudinally of the frame, plural rows of longitudinally spaced scarifier teeth projecting from the roller for working the soil, and stationary teeth mounted on both the front and back longitudinal portions of the frame and projecting between the scarifier teeth. Each scarifier tooth has a hook member projecting laterally from the tooth in the direction of movement of the implement to engage branches, roots and other plant growths for slashing, crushing and cutting them against the stationary teeth which have cutting edges facing the hook members so as to provide a pulverized mixture which is thereafter mixed with the soil.
