I've never seen a Bison II, but from your description it sounds like it's nearly identical to the S630, Satoh Bull. I had one, very good little machine. Uses a 25hp Mitsubishi diesel, while the Bison (650g) used a Mazda gas engine, also common on some forklifts. these were made for the North American market, so English manuals are available, at least for the Bull and Bison, Not sure of the Bison II.

Much more noise and vibration than the later 3 cylinder versions from Mitsubishi, and Yanmar.]]
