I just bought a 1983 Ford 165 garden tractor with a 16hp Kohler engine. It has all manuals and has been very well looked after. It includes a snowblower, lawn mower, tiller and front plow blade. Does anyone have any info on this tractor? It has been very well maintained, and I feel confident that I got a good deal. One thing I'd really like to do is increase light output - any suggestions?
