New Holland T4.75 power star hydraulic problem

[NCJim919]

New holland said the filter base was probably cracked so I replaced it and we inspected the suction pipes again . We saw no cracks in the pipes replaced the filter again . It still jerks on the loader when it gets warm . I removed the loader and baled hay for 4 hours and you can fill it jerking on the small door lift cylinders on the baler . talked to several new holland people they don’t know what is wrong with my tractor . Everything has been replaced the pump, lrelief, loader controls, filter base . Is there something in the remotes or 3 point hitch controls that will act like it is loosing pressure for a second like air in the system

I wonder if your 3 point is miss adjusted and trying to lift to high and bumping up against the 3 points internal relief valve. If you lower your lift arms to about 1/2 or 3/4 full lift height does it bother.

I don’t really know next time I get it out and get it hot I will try that and see if that makes a different Thanks I will let you know

Sound like your 3 pt piston is leaking by to me.
