Engineered for maximum production and service life The D8T mainframe is built industry-leading tough – heavy steel castings, full box section frame rails and continuous rolled sections on top and bottom frame rails provide the strength to absorb high impact shock loads and twisting forces. The D8T pivot shaft runs through the mainframe and connects to the roller frames, allowing independent oscillation. The full-length pivot shaft distributes impact loads throughout the case, reducing the bending stress on the case. The Tag-Link brings the blade closer to the machine for more precise dozing...
