One of the most popular Our Gang shorts has been 1936's "Divot Diggers", which contains the Little Rascals and a pet chimpanzee being hired by a group of golfers as caddies while they try to play a game of their own.

I have been looking for a copy of this. Somebody from Russia uploaded a copy of the film on YouTube:

So why do I bring this up? Pay attention to the chaotic ending of the film. It involves the chimp in a chase with a tractor. The question is, can anybody identify this tractor? I'll post as many pictures of it as I can.
