The two rotors are small diameter (17 inches in the TR's and CR's up to the 970 which is 22 inches). This gives you a large amount of centrifugal force to separate the grain out of the straw mat and also this allows it to be more grain on grain threshing instead of grain on metal. With these small rotors in wheat you usually find most guys running the rotors at 1700 rpm which if you haven't run one before sounds really fast but being so small in diameter the tip of the rotor isn't going any faster than a conventional set for wheat. I know that in the years we have been running a TR we have found it to be very gentle without cracking grain.
