ABSTRACT:
A system and method to allow a paving machine to form tight radii in continuous extrusions such as curbs and gutters is disclosed. A shift cylinder is used with the steering mechanism of a typical paving machine to allow sharp radius turns. The steering cylinder is used to pivot the track of the paving machine about its leg and the steering cylinder is used to pivot the leg relative to the frame of the paving machine. A hydraulic circuit is operator activated to allow fluid flow through a flow divider to ensure each cylinder operates in concert.
