A large stump knocked off the rubber hydrolic line connection on my TC 35 while I was mowing a deer lease.
Lost PTO power and all lift. Left the mower in the field and drove the tractor home. I replaced the rubber union and replaced the hydrolic oil filter since it was about time and added lost oil. The 3pt hitch only lifts when the engine is reveved up. And it lifts in spirts.
Any suggestions as what to do next, my mechanic told be I do not need to bleed the hydrolic system.

Certainly does sound like an air problem, check that it is still full now that it has run a bit, if it is then try running it a little more and cycling it up & down to blow the air through the system.
If you only took a line off I can't see much else that it COULD be. There's a really slim chance that the hydraulic pump got starved of fluid enough to heat up and damage seakls but I've never seen it happen, and I 've seen some REALLY empty reservoirs in my time.
Best of luck. ....

Try removing the mower and raise the hitch full up to full down several times to purge any air that may have entered the system. If this does not work, the pump may be hosed like Murf said. ....

Was it the suction line? If it was, I don't know how driving home with the pump running without an oil supply might affect it. Hope it turns out to be an easy fix.
No matter if it's suction or pressure side, I'd check for obstructions that might have entered the system through the break. On the pressure side, a disconnected quick-connect would likely close the line and open the relief valve. Driving for very long in that condition wouldn't do the pump any good either.
