Bought this 440 a few weeks ago. It is odd in the fact that all of its ag components were removed and a large generator was added. No PTO, no 3 point, no drawbar. It has a brass tag that says "chev" Indianapolis indiana with a ID number.Generator works good.Went to replace the fan belt and found a 6 blade fan that seems to be a pusher.... I don't think this is right. Turned the fan over and now it doesn't move any air. Fins are not orientated for rear flow. I think the original fan is a 4 blade fan with rear pull toward the operator. Has anyone seen this machine before. I suppose it was built by a maintainence shop for a factory for remote power source. Here are some pictures.
