4110- 3 pt hitch wont raise

[Gumby542]

So I've got his tractor all back together. However, I do not have any control of the 3 pt hitch or mower deck. The rockshaft valve was out of it, and in pieces when I got the tractor. I rebuilt the valve with new seals and reinstalled it. When I go raise the deck or hitch, it doesn't move at all. Also, when I run the FEL at idle, it causes the throttle to surge up about 300 rpm. Not sure if the two are related or not. Hopefully someone has dealt with these before.

Check the rate of drop valve/knob below and in front of the seat and make sure it is at least turned in. Whoever took the rockshaft out might have backed it off all the way.

I tried opening and closing the valve. It didn't do anything. Wondering if maybe a bad component in the rockshaft valve itself? It bought he reason it was apart was because the seals were bad. Maybe it was a component too.

There could be a huge air bubble in the system that needs to be worked out.

Go here and read one way on how to bleed the system

I think rate of drop screw only controls lowering not raising of 3 pt.

What about the sensitivity screw adjustment...was the screw locknut position moved?

 

[Gumby542]

Is that the Allen screw with the lock nut on it? Anything is possible given it was in a small Rubbermaid tote. Do you think the FEL changing the rpm is even possibly related?

Yes, that's correct, but I can't recall without going out and starting mine to check, if, when backed out all the way the 3 ph doesn't do anything.

I would think if it were closed, the hitch wouldn't do anything as no fluid could pass through. That's why I tried playing with it as a first step

No, with it closed all the way nothing happens, but I can't recall right off if having it open all the way will cause the 3 ph to not do anything either.
