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??????????????
