Just operate all your controls. Raise the rear lift up and down and the same with the loader. By doing so it will self purge.
I am replacing a damaged hydraulic line on a Bush Hog 2045. Does the same advice hold true? I'm new to this stuff and have to ask a really dumb question - but - here goes... where would someone hide the tank? I'm going out to look again...

Yes, Moot, same applies to you. Just operate the control to cycle the cylinder and the air will bleed out. As far as the tank, do you mean on your tractor or what? More info needed please...
Yes, I guess it would be on/part of the Kubota L3010. I traced all the lines on the loader and it looks to me like all the fluid is supplied from the rear PTO housing? There is a red 'oil' fill cap and a small glass site gauge. Is that it?

Yes, that is correct. The oil "tank" is the rear housing. To check the fluid level make sure the FEL and 3PH is fully lowered, the oil should be about 1/2 way in the sight glass.
I guess you do not have a manual for your tractor?
No manual... I'm still looking for one.
Thanks for the info. Out of curiosity, where does the air go? Should I leave the 'oil' cap loose? Also, I guess I'm going to have to replace some fluid. I believe it has the Kubota Super UDT. Do I have to use that?

The air get pushed pout of the cylinder seals or ends up back in the tank where it dissipates. There is no need to leave the cap open.
As far as what type of fluid-I can't answer that as a JD guy...but if you use the search feature you will find your answer I'm sure.
