My tractor serial # is 800181, a late one compared to yours! What is different about mine though is that it has no threaded holes in the casting on the transmission for floor boards. Even after sandblasting and digging I cannot find any. I have 3 80 standards and a couple 1931 parts tractors and they are all the same. My whole transmission cast is different slightly around the drawbar as well. I am picking up new fenders at Lancaster to complete my restoration but I think I am going to have to make my own mounting system for the floor boards. I checked the row crops as well and they too are different. I have no implication in the serial 3 as to a differnt trans. It has me stumped. I've looked at 2 dozen 18-28's and a half dozen row crops and I am still baffled. I think I know your tractor, got some nice pictures of it at Midland and maybe Canandaigua. I live 15 min from Canandaigua. Hope to feature Hart Parr again there soon. Maybe get better luck with the weather.Thanks for the info though, guess I got a regular 18-28. Taken me 5 years to restore the damn thing,(I'm not done yet) had it for 18 years now. F&amp;H rear wheels were rotted off and I had to find steel and a manifold, waiting paid off though, picked up a beautiful manifold 5 yrs ago with carb for $100. These things just take a while is all. 
Thanks again, Adam


   [quote:2fy8dwoc]What is the serial # of your 1930 18-28? If it is 800075 or earlier, it would be a 2-3 plow tractor, rather than an 18-28. Some confusion with these tractors, the first 75 were never produced as 18-28's, and there were some changes made on #76 and later tractors. I have #17, and after researching this tractor with the Charles City records, compared it to Jim Kline's 1930 18-28, the results of the research was conclusive.[/quote:2fy8dwoc]
