Starting Dave and Dick Krueger's F-20 narrow on steel. It's been sitting for about four years and the fuel line is plugged, so it runs lean shortly after starting, but what a sound!
In 1955, I was 7 yo, and my Grandfather had an F20. It looked very much like this one, except it had taller, skinnier steel-spiked wheels, like the ones on the F14 and F20 "wartime" A's on these YouTube Videos. It also had pneumatic tires in the front, and it ran on "tractor fuel", which I believe was kerosene, from the smell I remember. The coolest sight was to see those shiny steel spikes sparkling in the bright sunlight when coming in from the field for the day. I remember that huge front frame and steering box, the huge air cleaner, the steering shaft running straight on top of the engine cowling, and the sound of that engine with no muffler. A "REAL" machine ! That same year, I learned to drive on a Cub, and a WW2 vintage "real" Willys Jeep. I had a hard time reaching the pedals on the Cub at 7 yo, and I had to use a stick to push the gas pedal on the Jeep, which made for some rough riding on farm roads. My Grandfather figured I couldn't hurt anything on the farm. But, at 10 yo, I was plowing with the Cub. So thank you for refreshing wonderful memories !!!
