I have a 485A backhoe coming in a few days
I found the operators manual on the JD website and looking at its grease requirements JD recommends HD Moly Grease. Of course this is different than my tractor and loader which I use the JD recommended SD Polyurea Grease, I also use this grease in all my trailer wheel bearings, tie rods end, ball joints, etc as this grease is GC-LB (chassis & bearing) rated. Makes things simple.
I would really prefer to use a single grease for everything, not sure if that is possible with the moly requirements of the backhoe.
