Have your TR's not been good enough for you or whatIJ If you have the money to buy a new combine, why switch brandsIJ The TR's are great, especially where gentle threshing is a must. The new CR I know from experience is several times what the TR's were, and I love Twin Rotor Combines. THe new CR has it all. The best reverser, best stone EJECTION(not trap like most combines) biggest, most comfortable cab, and all around performance, from the twin rotors to the Self leveling Shoe. The CR combines will not be matched for a long time, if ever. I know New Holland has had some problems with some of their tractor lines, but the combines are very dependable, and proven.
