I'm looking seriously at buying a Satoh/Mitsubishi S470 "Buck" Tractor with a FEL, backhoe, box scraper and rock rake. The price is very cheap. Only problem is the engine is starting to knock. Parts are readily available, but the wife doesn't want me to get tied up in another long-term project (Gee--I don't understand why she would feel that way!!???).
So rather than rebuild the engine, I'm looking for a good runner that will fit in it.
I understand that the Mitsi K3As are the same block and can be used though they're less hp. I have a source for them, but don't want to use it unless I can easily tweak the fuel system and get some more hp from it.
I know the same engine was used in the Bolens HDT1000, and some of the Iseki-Bolens tractors IIRC. Toro also used K3-series engines in their mowers--the 325D is one that comes to mind.
So, I need to find a price on a good running K3B, or any of the newer K3-series engines if they will work without major modification--I don't mind swapping out bell housings, etc.
Please let me now what you have and what you want for it.
