"Every time I get near may tracter the desire to play makes me forget about crawling around the rear wheels looking for numbers."
So have I...until I read your message! I headed outside and check...there IS a stamping on the wheel--Japan, tire size, then 3 numbers-"283" in my case. Wheels made in Feb. 1983? Mind you, this is assuming tractor is still "whole". I figured with my serial # it to be about a 1984, but I suppose 1983 isn't out of the question. Any further thoughts?
