Had a bad leak in the large rubber hydraulic line from the pump to the steel line at the rear of grain tank. The steel line then runs along the tank to under the cab. At any rate, lost lots of hydraulic oil, replaced hose, refilled resevoir but now the line is making a bad howling sound and I think there is air in the system....how to get it out? The head raises and lowers fine and is not "studdering" as I thought it would do if there was air in the line.

444 head....deck plates are wore, dad went to see about new ones and he returned to say something like $190 per set times 4...WT??????????????

Don't know about the hydraulics, should purge itself of any air pretty quick. Check shoup on deck plates, I think they are $20 or so each x 8 for your head, two plates/row
 
I had that one time after replacing the hydraulic hose on a tractor. I took the new hose back off and looked in it. It had a reducer like hole down in the hose. The line couldn't give full flow. I don't know why they would make a hydraulic hose like that. I obviously bought the wrong one. Once I put a different hose on, the noise went away.
 
You know....that may be the problem.I had the JD dealer make up the hose and told them to put a swivel on the one end because I was afraid I'd have trouble getting it on this funky location.

Will it hurt anything just to leave it the way it is? I picked 10 acres before it started raining the other day and the sound never changed. Thanks for the hint.
