We have a horse farm, so this tractor is my Batwinging/round baling tractor. It's the big 'un on the farm. I hadn't seen a UOA of the JD break in oil, so I figured I would post it up here. Looks like it's a little weak in the ZDDP but has quite a bit of calcium for detergent? Is that about right? I'm kind of new to this oil thing.
