Patent ID: 8342610

Claim:
A green concrete saw comprising: an undercarriage, a mainframe mounted on the undercarriage, the mainframe supporting a circular saw blade, a major adjust assembly including a ratcheting plate rotatably secured at a bottom end to the undercarriage and having a plurality of horizontal notches that are vertically stacked relative to one another defined in an engagement side thereof, selectively directly engaged by the mainframe and configured to adjust a height of the circular saw blade relative to the ground by adjusting a position of the mainframe relative to the undercarriage, a ratcheting plate biasing assembly, a fine adjust assembly including an eccentric axle, rotation of the eccentric axle adjusting the height of the circular saw blade relative to the ground by adjusting a relative elevation of the undercarriage from the ground, and a control assembly including a major adjust lever connected to the ratcheting plate via a major adjust cable; wherein the notches in the ratcheting plate are sized to receive an engagement edge of an opening defined in the mainframe, and the biasing assembly biases the horizontal notches toward the engagement edge of the opening defined in the mainframe, wherein a rear end of the mainframe is pivotally secured to a rear end of the undercarriage, and the major adjust assembly adjusts the pivot angle between the mainframe and the undercarriage, and wherein the major adjust lever is adapted such that actuation of the major adjust lever causes the major adjust cable to pull the ratcheting plate away from the engagement edge of the opening defined in the mainframe.
