Nice tractor! I had a ‘47 John Deere M a few years back and a ‘41 John Deere B. Does this one run? I flushed everything on mine with kerosene. Crankcase, transmission and gearbox. Gets all the crud out and then you can start with fresh fluids. My rear rims had been filled with fluid and completely rusted through. I cut the outer rims off and welded new centers on them. I had a sickle bar mower with mine that did well mowing the weeds out of the ditches along our road.
