My grandfather's home-made lawn tractor

In 1975, my grandfather built his own lawn tractor from spare parts he had laying around. Of course, it helped that he was a master machinist with over 50 years as a tool-and-die maker. For literally NO MONEY, he made a comfortable and versatile machine for yard work and hauling loads of dirt and rock. For this episode, I'm joined by my father, Paul, who discusses my grandfather's long history in the machinist trade and the ingenious ways he used materials on hand to make a machine that lasted for decades.
