My '67 4020 PS does the same thing only to the left. Doesn't seem to do it as often when only running about half throttle. Only does on the road. Thanks for the advice, Tim.

This is a common problem,,and mainly because the most of them have never been resealed,, they have done a "Lot" of steering the last 40 years. Deere offers a kit, but it doesn't include the large lower pinion seal, they can be ornery to repair if it's your first one, when any of you guys get ready to do one I'll post some pics and hints on doing them,,don't wait too long to do them as they can put you in the ditch or worse yet oncoming traffic...

Our 4020 pulls to the right expectantly in road gear too. I would appreciate any hints you have to fix it. Thanks.

Larry, it"s usually the steering motor, down front, when the seals get worn the pressure that normally holds every thing tight leaks off causing a void or low pressure in one of the cylinder sides this lets the wheel dart one way or the other, it won"t show up as much in the field because you are correcting your steering more often and this compensates for the leak off. Deere offers a re-seal kit but they don"t include the large lower seal in the kit,it"s not a bad job to repair, when you get around to doing it I will walk you through it with some helpful hints.
