Well now....
I've heard a few thoughts on this one...
The way it's done in many industrial systems is each end of the cylinder has a bleeder screw. You just crack the screws open and cycle the cylinder a few times until no air comes out.
Since I've yet to spot bleeders on any of the tractors I've looked at, I'd suggest the next best, which is to ever so slightly loosen the hose fittings and then cycle the cylinder a few times.

A WORD OF CAUTION: do a google search on HYDRAULIC INJECTION INJURY

I'm sure you don't want that type of injury! Be careful working with any hydraulic system as high pressure leaks can easily penetrate the skin!
If you'd rather try a more cautious route, you may be able to purge the system satisfactorily simply by hooking it up and exercising it a few times to its limits.
