Re: Can you mix 85w 140 and 90w 140 in final drive?

You can do a lot different things, several years ago my reverser box on 7720 started to leak, with 200 acres to go, I just filled up gear box with john deere corn head grease, maybe 4 tubes, and kept on.  Had no problems and replaced seals and bearing in the winter season.
