A green concrete saw that allows for precise adjustment of a height of a circular saw blade is provided. The saw provides for the circular saw blade to be secured to a front end of a mainframe mounted on an undercarriage. A major height adjustment is performed by adjusting the height of the mainframe relative to the undercarriage. Further, the undercarriage supports wheels for the saw, and a fine height adjustment is performed by adjusting the height of a front end of the undercarriage relative to the ground through the use of an eccentric front axle.
