My father got this cat from his father who owned a small sawmill.  Dad says that it was the first ones made.  It has had changes made as it was a working cat.  Wider tracks and has newer rails.  Last ran in 2009.  

New photos showing 1925 date.
Wide tracks, straight front blade.
Dad says the starting engine is gas and is in great shape!

Welcome to the group, we always like pictures. Probably as many if not more old Cats working than all painted up for show tractors.

Welcome! Heck, don't keep us in suspense, tell us some more about the RD4 please. If you don't, I'll have to bore some folks here with one of my own stories, and they wouldn't like that much! JM

My grandfather used it for his sawmill which was used to cut timber.  He made some changes because it was necessary for the job it was doing.  He replaced the narrow tracks with wider ones.  It has a straight blade on it.  He had just replaced the rails a short time before he passed away.  He had told my dad that that cat model was from the first of that model.  That he had bought it the year it came out.

Dad moved it from the mill to his property in 2009.  He drove it onto a trailer and drove it off again.  It has not been started since then, but it was working.  Dad said that it has a good gas starting motor on it.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
