JD 4110HST
I have a JD 4110hst with a hitch problem. There is a lever on the right hand side (as you sit in the seat) that raises and lowers the three point. There is also a sliding stop to facilitate maintaining a certain height for the attachment, if need be. The lever travels about 7 inches (+ or -) When new, the lever could be stopped anywhere along the route of travel and the implement would hold. As time went by, the "active travel" distance got smaller and smaller. In other words it took a shorter distance to be all the way up (or down) It is now about two inches. It still goes all the way up and down, but the adjusting distance is getting very touchy. I have a service manual and have done all the adjustment possible. Does anyone have any clue as to what might be the problem and/or fix?

PK,
Mine still works normal-I've not experienced or heard of anything like that before on these machines. I'd have to think something in the control valve is amiss since you've done the external adjustments.

I'd take a REAL close look at all that feedback linkage again and see if one of the pivoting cams are frozen in place. When they do it acts just like what you're experiencing.

Thanks Oldtink. I am afraid you lost me with "feedback linkage" and "pivoting cams" I don't see any linkage or cams or are they internal?

thanks Kenny. I will keep a close eye on it.

I'll guess something is not adjusted correctly with this linkage.
