Charlie,
Looks a lot like the buzzsaw I have, except I've got paint on mine.
Used to use my Farmall A to run it, but that tractor died a few years ago and I never used it again except for parts for my Super A that I use for mowing.
Last time I ran the saw I used my Field Marshall tractor to power it as it is the only running tractor I have that has a flat belt pully.
Might have to try running it from one of my stationary engines some time.
