I've admired Shaw Du-All tractors at shows for years but have never had one nor know much about them...I'm eager to learn though!
I was contacted recently by a gentleman offering me an R-7; what I'd say is a project tractor. The way he described it is that it's all there but has a replacement engine in it.
-When were the R-7's manufactured?
-What was the original engine used in an R-7; Briggs ZZ?
-Were hoods an option? (He mentioned that this tractor doesn't have a hood.)
What were the various Shaw Du-All models? I've heard of an R12 with a twin cylinder Wisconsin engine, R6, R8 and now this R7 but honestly don't really know the differences between any of them.
Thanks in advance for any education!
