Bob and Roger talk about working side by side in the dealership, building and repairing the tractor together, winning championships, pulling at the Iowa State Fair, and the friendships built through years of competition. It’s a story about horsepower, problem-solving, family, and the kind of determination it takes to keep showing up, even when the tractor keeps coming home broken.If you love Allis-Chalmers pulling history, father-son tractor pulling stories, and the behind-the-scenes work that goes into building a competitive machine, this is an episode you won’t want to miss. #BreakingBarriersPodcast #TractorPulling #BobMcKim #RogerMcKim #AllisChalmers #Allis180 #SuperStockPulling #PullingHistory #TractorPullingHistory #IowaTractorPulling
