Great old tractors, and there are still plenty of them working today, although I wouldn't want to be using my old M for much these days. Both it and I are too old and cantankerous, so we probably wouldn't get along very well doing serious work. Remember these big old gassers were designed back when gasoline was 30 cents a gallon and nobody paid much attention to filling the 20 gallon tank twice a day. But getting on it sure brings back the memories and what a kick to use for a hayride!
