Yeah, Laitch, been there.......I'd take a K75 motor, probably better match, seeing a URAL is only 50 hsp. at best. But would have to transplant the whole drive train fo it to work....wouldn't trust the URAL drive. Have you looked at the URAL frame.....I think they use the same one on the URAL tractors! Actually, this motor swap shouldn't be that hard into a URAL.......hmmmmmmmmmmm.
