Was working on a tractor and this appeared on a trailer......

My friend Frank brought us a gift! A buddy was junking it!! The rear was "seized" and was parked two years ago. I got under it with hammer and screwdriver, hit brake and was moving! ;)
Tried fast to fire it up, no go as I did not want brake to seized again and safety is operational. Another to work on! Seems to be a good machine!
