with all the talk of high horsepower tractors, I'm thinking the diffs might not be able to take all the power. SO, what if some brackets were created to install full size 12bolt gm truck differentials into a tractor. (I'm even thinking about having a dually tracker)
The wider axles will keep the tires further out to prevent rubbing in turns. Think how much fun a 6x4 tracker would be, on 6- 33 inch tires
