John Deere 820 Tractor.
Rebuilt the carburetor on the pony engine for this old John Deere 820 tractor.
The tractor is a big, twin cylinder diesel. A tiny, V4 gas engine is mounted on top. The pony engine is started with an electric starter and once it is up to speed, a clutch is engaged to turn over the big diesel engine.
I think Rube Goldberg might have been employed at John Deere.
