Jay Leno’s Garage welcomes every motoring-related thing regardless of its shape or function. If it has an engine, and serves a good purpose, it’s welcome. It’s even better if the vehicle has a cool history, like this Lamborghini R458 tractor. Built back in 1968 in the same factory where Ferruccio Lamborghini made the Countach and Miura, this tractor is a rare piece of kit restored enthusiastically by Bill Scott.
