Abstract A spring cushion shank mounting assembly for an earthworking tool including a bed bracket, a shank support assembly, a shank, and a spring assembly. The bed bracket, which is formed from a steel plate, includes a center section attached to an implement frame, a transversely extending depending rear flange with an aperture and two spaced depending front flanges. A shank support is positioned adjacent to the center section of the bed bracket with an arcuate rear section in contact with the transversely extending depending rear flange at each side of the aperture and an elongated guide member limited to vertical movement in the slot formed by the two spaced depending front flanges. One end of a shank passes through the aperture and is connected to the shank support. The spring assembly biases the forward end of the shank and the shank support toward the bed bracket.

A spring cushion shank mounting assembly for securing an earthworking tool to the frame of an earthworking implement characterized by a bed bracket with a center section adapted to be attached to an implement frame, a transversely extending depending rear flange with an aperture, and a pair of transversely spaced depending front flanges; a shank support including an elongated center section positioned adjacent to the lower surface of the center section of the bed bracket, an arcuate rear section in contact with the transversely extending depending rear flange at each side of the aperture, and an elongated guide member attached to the forward portion of the elongated center section of the shank support at substantially a right angle to the elongated center section of the shank support and positioned between the transversely spaced depending front flanges of the bed bracket and extending substantially from one flange to the other thereby limiting the elongated guide member to vertical movement relative to the bed bracket; a shank extending through the aperture in the transversely extending depending rear flange of the bed bracket; connecting means for connecting the shank to the shank support; and resilient means for biasing the forward end of the shank support toward the center section of the bed bracket.
