L3710 rocker shaft won't go up or down

[Rat4020]

New to your forum Thanx for letting me on board
The problem I have is all of a sudden the rocker shaft quit working up nor down .. The speed selector valve makes now difference . Any clues

If it was a sudden onset issue, could be a pump issue, filter or suction line issue.

Does that pump supply to the loader also because the loader works as it should
And yes it happened all at once

to be clear, we are talking about the up / down function of the 3 pt hitch, right?

in another thread I read about the internal parts of the relief valve sticking closed. if that's a possibility there were solutions to that issue posted in other threads. I don't have a link, but google does.

Yes the up down of the rocker shaft or three point . I checked the slotted flathead screw on the valve under the right floor board and it's were supposed to be ..like I said the loader functions like it should..
I'm leaning towards the control valve.

Found the problem lol I didn't say this was my tractor mine is a b7200hst the l3710 is a guy I knows
Here's a pict of the problem

is that the head of a piston? how did the rod wind up going through it?

Pretty unusual for that to happen.
I would say he was either lifting too much weight too often, or loading it heavy and bouncing the weight on the three point.
