Thank you for your good words on such a wonderful class of combines! I love the TR's as much as any. You are right about the passing years. it doesn't seem like that long ago, when i first read about a new rotary combine in Farm Journal in 1975, the year the TR 70 made its debut. Actually, I was drawn to the article because at the height of new fuel efficiency concerns and a certain make of car new to America, I thought it was a combine with a rotary engine. I first saw the TR 70 in real life, at a farm show in 1977. I was really impressed. When another leading rotary came out later the same year, it was an odd-looking combine, leaving the TR to be the only rotary that still looked like a combine. When still yet another rotary of another color debuted in 1979, it sure made that red rotary look pretty good [appearance]. I would like to see more of the original TR 70 owners speak up, both pro and con. I once heard of some big farmer who had about 20 of them, but never contacted him. I agree on the naming of the combines as to the loss of the "TR" designation. Does this mean a new single-rotor unit as opposed to dual rotorsIJ
