Last fall I was mowing with my Massey 1135. I stopped for a short break shutting the pto off and ideling at 900 rpm for about ten minutes. I climbed back in and flipped the pto lever it started and the stopped. No hydraulics.

The charge pump was removed and could not see any evidence of failure. It was then notice that the pto clutch pack would turn by hand. Then removed the pto clutch pack and shaft for inspection.

I put the shaft back in and could not turn it by hand. I put the shaft on the clutch pack and could not turn by hand. Then both the shaft and clutch pack were reinstalled and it felt secure with minimum play. An hour later I check it again and you could turn it by hand. Shaft and clutch were both turning. It was like the shaft was not going in far enough.

Thank you for your help

The flywheel splines MAY have failed on the PTO input shaft, and there's also a rear coupler at other shaft end at the trans-diff split joint that can strip splines too. Loose EITHER one and ALL hydraulics will stop. I'd start with the engine clutch split and hope that end is bad as that shaft will pull out the front, and the front drive coupler replaced. If the rear one is bad too, the trans-diff split will need done also..
