I am wondering how much difference a change of tire size would make on a 1947 WC. It seems bit fast geared and I have to slip clutch alot especially in close quarters.
To do the math I need to find the numerical gear ratios for the tranny gears and for final drive. One search found suggestion that final drive is 4:1. Is this correct? Also what is modern equivalent size of original tires that originally came on this tractor?
