This channel is about our 7172 Duster we played with for a few years , then got into tractor pulling, my son Nick liked the pulling better than he did the racing and sold his Duster. We tore the tractor down in Jan.2012 and completely rebuilt it 20 months later we had our HOT FARM CUMMINS 466 3000 RPM . as of this date we have made 10 hooks with the new setup. 1 5 2015 We are still tuning and gettung seat time to learn how to drive his thing.
