Heres what I know, nine new models with two more coming later for a total of eleven new models. All will have high drive like the row crop, horespower will be smaller than the 35 challenger and go up to 500 hp. Will have finger tip control hydraulics like the deere. suspension will oscillate in the front end like steel track tractors.lots more electronics . Have not seen any pictures and cat is really being secretive. As a dealer mechanic I am excited about these coming new tractors. As far as the wheel tractor rumor goes ,caterpillar may have bought out Fendt or are working out a deal with them for their line or a line of tractors. Maybe simalar to the cat_claas aliance.
