ABSTRACT:
A cutting machine for cutting material from a crack that is present in a paved surface. The cutting machine has a circular cutting blade. The cutting blade has an axis of rotation and a mid-axis that is perpendicular to the axis of rotation. A wheeled platform is provided having wheels that are configured and oriented to cause the wheeled platform to turn about a predetermined point when the wheeled platform turns. A mounting arbor is supported under the wheeled platform. The mounting arbor retains the circular cutting blade in a position where its mid-axis generally aligns with the predetermined point around which the wheeled platform turns. The mid-axis of the cutting blade therefore remains in a fixed position when the wheeled platform is turned in a new direction. This allows the cutting blade to remain within the paved surface.
