16 Claims

Claim.—1. In a cultivating blade and carrier combination, an elongated carrier, said carrier and blade each being divided into two sides by a longitudinal vertical plane extending through each. one side being the advancing side and the other the trailing side, the upper surface of the advancing side of said carrier inclining forwardly and downwardly, said blade being secured against the forwardly and downwardly inclining side of the carrier at a forward and downward inclination with the advancing side of the blade projecting beyond the leading edge of said carrier, the trailing side of said carrier extending rearwardly beyond the trailing edge of said blade and inclining rearwardly and downwardly.

4. In a cultivating blade and carrier combination, for the cleavage of a topsoil layer, an elongated carrier, said carrier and blade each being considered as divided into two sides by a longitudinal vertical plane extending through each. one side being the advancing side and the other the trailing side, said blade having an undersurface and a scouring surface, said blade and carrier being designed to pass wholly under said topsoil layer after the cleavage thereof and thereafter allowing the same to settle unreversed on the soil beneath, said blade being secured to the upper surface of the advancing side of said carrier at an angle to the ground and in overlapping attachment such that the scouring surface thereof is elevated above the upper surface of the advancing side of said carrier, the advancing edge of said blade projecting ahead of the front edge of said carrier.

6. In a cultivating blade and carrier combination a cultivating blade carrier substantially elongated in relation to its transverse cross section, said transverse cross section being seen to be of inverted. V-shaped configuration at least upon the upper surface thereof, said blade being secured to said carrier so as to project in advance thereof to cleave a top-soil layer as herewithin defined, said carrier configuration permitting the passage thereof and said blade wholly beneath said layer following the cleavage aforesaid, and the subsidence thereafter of the layer unreversed upon the ground beneath.

13. In combination with a wheeled cultivator framework or superstructure, at least one standard carried thereby and depending therefrom, an elongated blade carrier, said carrier being considered as divided into two sides by a longitudinal vertical plane, one side being the advancing side and the other the trailing side. said carrier being secured directly to said standard at a locus on said trailing side. and an elongated cultivating blade removably secured to the advancing side of said carrier, all for the cleavage of a topsoil layer as herewithin defined and passage thereunder after cleavage while allowing said layer to settle back thereafter on to the soil beneath without reversal, the leading edge of said blade projecting in advance of said carrier and lying in a horizontal plane coincident with or below the leading edge thereof, said carrier leading and trailing sides being so mutually disposed that said blade is supported at an angle of not more than 55° from the horizontal when regarded in cross section, and overlies at least the portion of said carrier trailing side which is contiguous, with the leading side thereof.
