ABSTRACT:
A machine for opening the joints and random cracks in pavement preparatory to placement of a filler-sealer material therein. The machine includes an open carriage having an opposed pair of side wheels and a shroud mounted in the carriage intermediate the side wheels. A cutter wheel is journaled in the shroud for rotation about a horizontal axis, and the cutter wheel is driven by an engine mounted atop the shroud. The shroud is pivotably coupled to the carriage for raising and lowering of the cutter wheel by moving the axis of the cutter wheel in an arc which passes through the axis of the carriage wheels.
