Was able to get a gauge setup and checked the pressure and had zero pressure with the pto engaged. Decided to try removing the hydraulic valve without removing the entire transmission.
Removed the tire, the mmm lift linkage, diff lock linkage, and the 12 bolts through the frame rail. The frame rail has enough movement to be able to be pried out and just get the valve out.
Once the valve was out there was a small piece of silicon gasket in the 1mm flow hole. Removed that and verified it was clean and reassembled the valve and 12 bolts, started the tractor and tried the pto and nothing.
Disassembled the valve again and more gasket material. Reassembled it again and again nothing. The third time disassembling and cleaning and all is well. The pto is working like normal just like it has up till now. When I get time in a few weeks I’ll probably drop the trans fluid out and change the filter and clean the screen. Disappointed it took all of this but glad it wasn’t a major failure.
