They often call me to find out what authentic part will fit a particular year of tractor. Some days, as many as 25 to 30 people come to the farm, to visit the museum, to buy parts, or to conduct other tractor-related business. From July through September, Fossum and Harriet are gone nearly every weekend, hauling tractors to parades, promotions, or other exhibitions. His collection has been featured in seven books about antique tractors. I particularly like helping young enthusiasts, young hobby farmers who want to learn more about these tractors.
Some business transactions involve shipping parts or tractors overseas.
For instance, Fossum shipped steel wheels to a collector in Australia, and he sent a rare 1924 Fordson tractor-mount plow, a Ferguson Duplex Hitch plow, to England. A similar model remains in his collection. A Model 2N sugar cane and cotton special. Model 8N with Bombard tracks. The tractor he treasures most in his collection is the Ford Model 8N that his father bought in 1950.
