It looks like it snagged a truck or something solid a road speed to bend the LH wheel like it did and cracked / split the case.
These were good solid tractors and the parts are not that bad from salvage. Same parts as 574/584 IH. I think for $500-1000 more you could have a decent tractor.
If I needed one, I would take the deal but always try to get it for less as you will have to buy a new case and wheel as well as some of the internals.
Good luck!
