Hi Grantj, if you look at the track frame mine had 2 rollers thet where taken off and capped and the single field changeover fitted as per the parts book.

Why do some of these RD4s have single upper roller? I thought that they changed to single after they started calling them D4. I realize that the history of the timing from RD4 to D4 is a bit foggy, but I thought the double uppers were only on the RDs? There is a lot that I DONT KNOW, so maybe someone can straighten me out. Grant.

This is my 1937 RD-4 4G3317W she has 20" track pads and a Letourneau blade. I purchased at an auction with no info but it looks to be an older restoration on a machine with almost no wear showing. The pre-,cleaner is missing and the left and right floor plates but I have a parts machine to rob from for those. A seat would be nice.
