444 3pt hitch

metalmender · May 23, 2014

as my 444 warms up, the 3pt lift arms start to lift very slowly and this usually takes place after an hour or so of running, steering does not seem to be affected or the hydraulic remotes. are there "O" rings on the piston inside the top cover to actuate the 3point hitch? can this piston be removed out the front of the top cover to change the "O" rings? the hydraulic system is currently using IH Hy-Tran fluid
thanks in advance

Hi, Does your 444 have dual hydraulic pumps or single pump with a priority splitter valve for power steering. There is also two valves on the 3pt control valve body on front of hydraulic housing by front of the seat. One valve in a 3pt shut off valve and the other is a flow rate valve for 3pt, push in a turn a half, reduce flow to 3pt to 3 gph, valve out allow 6 gph to 3pt. There is also a hydraulic suction line filter in the hydraulic housing that could be restricting hytran flow.
