1850 3 point

[too many interests]

Evening all,
A week ago our family"s 1850 3 point quit working correctly. My grandfather had a winch on and it all of a sudden would not lift it, but the loader still worked strong (plumbed through the remotes). With no load on the 3 point, it raises real slow and will not support a person standing on the arms. My question is what is the most likely cause. I am going to start tearing into it tomorrow. I have a repair manual but would like opinions.
Thanks
Chris

I would check releif valve on lift cylinder and the elbowits threaded into. If no problems there check likage and servo valve.
