Pretty cool! Way to breath some real life back into a worn out toy. Your son is going to beg for his tractor back, though.

I'd be curious to see more details on your PVC axles, and how you mount the pinion and ring gear inside of them. Kind of cool that you'll be able to tune the differentials for a limited slip action. I had thought about running some 1/8 scale buggy differentials in my tractor build.
