Good point dds,
Also notice the track center drive band and how it is driven buy the front pulley, instead of sprockets driving aginst the grouser bars. Any bets on how well it drove the tracks? I was thinking on the other one, maybe the center drive band in the track was notched for a bar inside of the driver pully. Nope, just serations inside of the pully tograb the tapered sides of the drive band. These track rubber parts would have been unique, and thankfully they changed them later, or today replacments would be MUCH harder to find. As it is on the later machines, the steel parts and some grain leg belting is all you need to replace, and freshen up the tracks. I'd have to say they did the right things on the later machines. But this one is pretty cool in that is shows the development of the track system.
It is probably a good thing it is located in Sweden, as I bet the parts are still hard to find, but MUCH easier there than anywhere else on the globe, I bet..
