I put contacted Joe Boggs at Mid West Equipment ( www.tracksandtires.com
) about 3 years ago...bought a set of the Solideal/ Camoplast "Crossfix" or "Crossfit" tracks. ....can't remember exactly what they are called. ...ran them pretty hard for concrete removal and excavation work....just work them out, ordered another set with out a second thought. One of my friendly competitors has switched his fleet of 4 Takeuchi CTL's over to these tracks as well. Good price for a GREAT track.
