Actually, White Farm did engineer that rotary combine, but MF had one in R&D that looked about the same, White filed a lawsuit against MF for patent infringments, when White ran into to financial trouble, MF took over the White combine factory, combine the two designs, and what they came up with is the forerunner of the MF combine there building today. Is'nt Caterpillar changing from Claas to AGCO something?
On the Cat Compacts, I think the Cat dealers buy those directly from AGCO with the Challenger name.
