Well I took your advice and it worked. When I pressurized the rear end with air I got a small drip of green fluid so I decided the tractor had to be really sick. After a couple more attempts I got a steady run of green stuff, I hit the starter and low and behold the red stuff shot about 3 feet from the hole. I fired up the tractor and in time the brakes work, the TA works and the clutch works. It took a little more time to bleed the steering and it works also. I drove the tractor out of the shop under its own power after sitting there for 2+ years. Always appreciate good advice.
