    1025R backhoe boom/swing control sticky and jerky

    Hi folks. Just picked up a 68 hour 2015 1025R FILB last weekend. Used it last week to mow and this weekend to remove and replace a small channel drain beside our driveway.

    My left control stick (which controls left/right swing and boom up/down seems to be sticky and it makes it very difficult to precisely control these movements. I sprayed some lube on the ball/clevis linkages but that didn't help.

    It looks like a little gasket is missing where the pushrod goes into the control valve -- see below. Three of the four rods have a gasket and the one doesn't. Would that matter?

    Any other ideas/suggestions?

    Tractor was purchased from an out of state dealer, very clean, lightly used. Still under warranty so I can certainly take it to my local dealer. Just wanted to avoid the hassle.

    Thanks!

    I will take a good look at mine tonight but I'm thinking that this is a wipe so debris doesn't get down into the controls. The biggest reason mine was jerky was because I tried to operate it at full throttle thinking that's what I needed. Actually if you move the throttle to IDLE and run it its much easier to control. Still not as smooth as I like it but manageable.

    I run around 1900 rpm and it behaves much better.

    Yes, I tried a few different RPMs. The problem is mainly a mechanical "stickiness" -- meaning that once I move the lever, say, to lower the boom, if I let go of the lever, it doesn't recenter. I have to pull the lever back into neutral and to overcome the "stick" I have to pull hard enough that it then nudges the other direction.

    I didn't use my backhoe at all this year. It sat outside in the elements uncovered. I know this is sad but just don't have the room for all the implements to store indoors. I went to use it a couple weeks back to remove a stump and I know exactly what your talking about. Mine appeared to have a mind of its own but I noticed it when I was actually hooking it up to the tractor which can be dangerous. But anyways out of frustration with the tractor off I grabbed the controller and moved in back in forth in all directions as fast as any mad man freed from a loony bin would. With luck mine came back to normal. I'm guessing it was a bit sticky from lack of use and by moving it back and forth it was re-lubricated as it should be. It also appears that the one you show as a missing part looks just like mine. So either we both are missing it or it doesn't come with it. I guess at this point without taking the valves apart I'm not sure what else to suggest.

    Seems like all the control valves are the same in terms of seals. I don't see a specific part number for the item referenced in the picture but it looks like they would be the last ring on the spool valve itself (Right most groove as pictured).

    A lot of threads on this, all seem to be a little different in how they happen but same issue. I still get mine sticking every once in a while, no rhyme or reason except that it only does it when the stabilizer is down with pressure on it. I've been doing alot of stumps lately and it has not happened, so who knows.

    The boom control spool valve is not like the others. What you have pictured is normal.
