    Big CPT Push Power

    in a

    Compact Package

    The compactness of the machine and its light weight make it convenient to mobilize to project sites.




    The compactness of the machine and its light weight make it convenient to mobilize to project sites. Larger pads on outriggers provide increased support when pulling tools in soft conditions. The newly designed, easy-to-use control panel gives the operator timely useful feedback.

    Features, Options & Accessories
