Well, it's IH built. So you can put that on your list of "pluses". Good running twins are hard to come by, so that's a plus too.
On the tubes: #1 I have tore down so many tires it isn't funny, if you actually can get the tires off the rusty rims, you will most surely rip the tube. #2 I think you will find the rear tires fluid filled. Rust on the R.H. rim is at the valve stem. I'm pretty sure they have fluid in them.
Looks like a good parts tractor at least!
