I'm not sure just what you're asking for here friend. You want help? Help with what? Do you need information or advice? Are you hoping for a source of used parts?
Not that my opinion matters much, but if someone I know were to approach me with that as a possible transaction I would suggest that passing on it. Unless of course, you are (or happen to know of) an authority on Japanese and/or Korean built compact tractors. There very well may be some used parts out there that will interchange, but knowing which ones, and from which brand/model donor to search from might be a daunting task indeed.
