I'm having trouble lifting round bales with a long 445, 3 pt hitch. Could there be an air pocket or what?? Trans hyd is full and 3 pt raises with any pressure on it. I would like to know how to blead the lines...if possible??

Generally tractor hydraulic systems don't require bleeding. Any air is pushed through the system back to the reservoir where it bubbles out of before it enters the pump again.

Clogged hydraulic filters and screens are usual culprits when hydraulics have reduced power and I'd change them if there's any doubt about their condition.

I don't know the tractor but you might indicate its HP and also how much the bales weigh. Tractortips says a 460 is around 40 engine HP with 18gpm hydraulics. If it's around there the tractor should be capable of getting most round bales at least off the ground. If it's much smaller the problem may be that the bales weight too much and the hydraulics are stalling. If that's the case you should be able to hear a relief valve opening.
