saturday, I bought a AC tractor wearing the CA decals. I took the serial number home with me, and looked on the serial number section, of the YT site, and think that I have a 48-49 C. Would someone double check for me? The number is C64461. It has a 3spd tranny, not the 4 spd one that I have been told that the CA has, and the drawbar is simular to the one on my 52 B, and not the snap coupler, which I have been told that the CA is supposed to have. It has an adjustable front end, and a 1 bottom plow hanging on the rear, which looks simular to the B type of mounting, with the little single cylinder doing the work, to raise the plow. The tractor seems to run ok, but needed gas and a battery, and air in the right rear, before I could load it.It has completely dent free sheet metal, two working lights, and what suprised me was the complete shutter system was still on it, and not froze up. I am now in the market for a set of cultivators, to put on it. All my tractors have to earn there keep. Please give me a shout, on the tractor size, and year. Thanks Ralph
