Here's a recent review from a customer with a 1025R JD tractor, which is very similar in size.
"I bought the Compact Post Hole Digger with 9 an 12 inch augers. I was surprised that they were easy to assemble on the JD1025R tractor - hoop, boom, gearbox, PTO shaft, then the auger. The hoop width was the minimum that would fit on the standard lift arm adjustment on my tractor (a wider hoop would also fit well). The hoop connected to the 2nd (from the tractor) hole in the boom, and the auger has about a 2.5 inch clearance from the ground. The gearbox was full of oil and ready to go.
I dug a few holes already, 24 inches deep, and I had absolutely no problems (in sandy soil with small and up to 6 inch stones). I was expecting to get the auger stuck as I learned to use it, but all went well for these holes. I still need to improve my skills at keeping the auger vertical, so it removes the dirt and rocks better, but the PHD did it's job well."
