Hello, Fellow JD tractor owner here. Grew up on dairy farm in Northern Wisconsin. We farmed with JD B, A AR, 60 and Farmall M. Quit and sold farm in 1979 (why the tractors are so old). Now many, many years later I have a couple acres of land and play around with a 2004 JD 4310, 430 FEL, 48 BH, Howse box blade, 5' Bush Hog, couple of 6' rear blades.
