Are you saying this site is only for discusion of Cat-Claus combinesIJ At the Ziegler (cat dealers) open house in Jackson Minnesota we saw no lexions, nor were they discussed in the 3 days of presentations. We toured the Challenger Tractor factory there and looked at the Challenger 660, 670, 680 combines. Hope this doesn't offend you but just looking at this site it appears the 680B is discussed here more than on the Massey site. Farm Fest at Redwood Falls is Aug 1-3 Maybe we will see What the Cat dealers have on their lot there.
