John Deere 4640 pto wont stop Problems

Just finished a major overhaul of this Project John Deere 4640 tractor. I can’t stop the PTO, the dashboard lever does nothing, the book shows some pressure test if it doesn’t turn. Personally, I think something has stuck from setting up for years. Any ideas.

It was the Powershift 8 sp tractor that was dead when I received it visually the connection is fine.

If it’s a series of Quad Range and you had a split on the clutch housing, it is possible that one of the PTO clutch plates has slipped off the hub and got pinched.
