    JD 4120 Transmission issues

    Anyone else ever have this happen with their 4X20 tractor with a PowerReverser Transmission? When I am in C range either 3rd or 4th and get over about 1500 rpm's I get a terrible grinding noise from the transmission. Slow down and it goes away. Tractor has about 300 hours on it and a month...

    Box blade hitch ball.

    Anyone else ever use their box blade to move goose neck trailers with? I mounted a 2 5/16" ball on the back of my Frontier 5 1/2" box blade by drilling out the existing center hole to 1" and mounting the ball there. Seems to work pretty well. Any thoughts or suggestions? Grady

    Has anyone successfully modified a 4X20?

    I know it's been discuss in several threads previously, but has anyone been able to modify a 4120,4320 or 4520 for more horsepower after their warranty was up? Thanks, Grady
