I also did the break in oil change today. On my old 425 changing the oil was so easy. almost didn't need a tool. Just a 10 mm to break it open, then turn by hand. On this new tractor, while they used the same petcock design, they made it so hard to get at. Can barely get my fingers in there. Had to use a small socket wrench and could barely get that in there. A chapman would help, but I can see it's just going to be a PITA no matter what. What were they thinking? Anyone have a suggestion on best way to get at this petcock? On the positive side, the built in filter oil funnel/tube is an improvement.
