Can I use the John Deere Multi Purpose HD Lithium Complex grease as an all purpose grease for my new 2038R. The manual lists this and the Polyurea as the recommended greases, but doesn't say much more. After reading through the past grease questions on this site, it seems that a lot of people use many different greases for different parts of the tractor. One grease for everything sure sounds nice! I already bought a case of the HD Lithium and now I'm wondering if I still need to buy other types of grease. Thanks guys.
