These were my Grandpa's trackers. To our best knowledge the one with the mower on it is the 1965 and the one with the plow on it is a 1966. Both are manual transmissions. The one with the mower just recently, the shifter is not shifting gears and feels loose. If I get the time I will fix it and get both of them fired up and running before a visit to see them. All I have to do is clean up the carb and install a battery. I used both trackers last year and cut regularly with the mower deck one (front yard only) and use the one with the plow every winter. They are stored in my shed year around as you can see in my pics. I also have a spare transmission that will be included as well has a spare mandrel for the mower deck.
