The JD moly for the loader (or hoe),and the poly for everything else. I can't find where I read it ,but JD does NOT recommend mixing these. Once you use it,stay with it.

I researched the mixing of polyurea and other greases a while back and while I found that warning with generic or other brand greases I recall that Deere said mixing with their own greases was OK. If you could find that non-mix info it would be helpful for us to look into it.
Polyurea is their most expensive grease and as I noted, is green in color and not messy. It would not provide the best shock resistance for a loader so I wonder if Deere suggests it on small loader tractors because it IS green and pretty. Most small tractors aren't going to be using their loaders for severe use and want it to look pretty and not greasy.
For bigger Deere tractors, they suggest moly-lith for the loader and lith-coplex for everything else. Polyurea is mentioned only for the axle bearings that are on a 300 hour grease schedule.
I stopped using polyure after my grease search of a couple years ago decided it was not the right grease for my loaders. Suggesting poly for small loaders must be a new thing since my JD790 loader manual suggests lith coplex for mild use and moly-lith for severe use. If anything has changed, I'm all ears.
For those new at this, there are basically three types of grease.
1--lithium complex for everything including car wheel bearings.
2. Lithium with a few percent molybdenum for shock resistance applications. Lith-moly.
3. Polyurea for certain bearing applications that require a thickened grease such as mower gearboxes and certain bearings operated at temperatures outside the normal operating ranges of most equipment.
