My buck saw. I built it for cutting up fire wood for my boiler and making charcoal for the forge and blast furnice.It is driven by my Farmal M or the H Using a 4" wide flat built.
That is similar to the saw we used when I was a kid to cut up sawmill slabs for firewood. Daddy ran it from a 1954 John Deere M (That my brother now owns and still uses) via a wide belt. Sure seems dangerous now that I am older and hopefully wiser.
