Granddad had a sawmill for many years. He started out with a Frick steam tractor for power and in later years switched to an IH gasoline engine.

Well into a set as witnessed by the stacks of lumber.
Nothing hydraulic here. Everything done by hand including turning the log.
On a good day they would mill 10,000 board feet. Dad firing the boiler.
