Satoh tractors?

Iv got a friend that has found a satoh
tractor really cheap. I think it a s650g but
don't really know it looks like a david
brown. What was we wad Wondering is are
parts hard to find for them and are they any
good. Thanks in advance

Parts are hard to find, out sourcing by Carquest, Napa, etc helps. For runners of the small tractor boom and decent machines.

Sato was advertised as the only Japanese tractor with a gasoline engine. It is a Mazda engine. Parts are expensive. The problem area I have seen is the governor wears out and is not repairable.

When I had a S550G, I tried to have my son who lives in Japan get parts for me, but he found that in Japan, parts could only be purchased by a licensed mechanic or a farm co-op.

A very good little tractor. They were made to look like a DB. We took in lots of 8N's on them. Lot's of parts available.

They are a good small tractor about the size of a 8N.
I have one that I have to get rid of as I can't take it with me.
It just needs work on the distributor.

"Lot's of parts available."

Where can you get these parts, and how?

Everyone else has said that parts are difficult to come by, and expensive.

Do a simple Google search ..... maybe "Satoh tractor parts" ....... you will get a good number of eBay links (so lots of stuff for sale there) and probably a couple of parts suppliers too. Yes, your tractor has an "uncommon" Mazda truck engine so don't think your local Mazda dealer is going to be anyh help, specifically one from an Australian Mazda truck version call a Goolagong or Boolabong from the early 70's I think. I think it's 1000 cc and parts are expensive, I paid over $100 Cdn for a simple carburetor kit. Check the four bolts holding the solid draw bar frame (not the three point) onto the bottom of the tractor, those can strip easily in the casting and are sometimes shimmed with shim stock from previously coming loose.

Type ..... Satoh-650G.com ..... into your address bar. Some info and specs, etc in there. Here's some info from that site on your engine ....

The Mazda engines used in the Satoh Bison S650G was also used in a variety of vehicles and equipment. When searching for parts at an auto parts store these vehicles may be of benefit.

The Satoh S650G shares its engine with numerous vehicles from around the world. Unfortunately many were not available in the U.S. but knowing them may still be of benefit when searching for parts.
