I restored an old Sears. Don't laugh, this was one that was made back when Sears had a fairly decent tractor. From what I understood, it was made by Roper out of Wheel Horse parts and it had the front mule drive and looked just like a Wheel Horse. It was the 48" hydrostatic model and it was built very solid. It had a generator on it that doubled as the starter, which is sure different from the equipment we use these days.
Restoring old things gets me thinking about farming with horses back in the good old days and you don't want to get me started on that now, do you?
