When I adust the tilt link adjustment, AND lock the assembly with the locking nut, the assembly will move a LOT during normal brush hog use - allowing the right side of the mower to drop 3-4 inches in an hour of use. If I use a HUGE wrench (14") to really clamp the locking nut to the top of the adjusting cylinder it will stay - but this is a huge amount of force to have to deal with all the time. Does anyone else have this problem and what did they do to stop the creep? I don't need to adjust it that often so a hydraulic adjust isn't warranted. But it gets very annoying having to constantly adjust it under normal operations.

I fought the same problem. Surplus Center, Surplus Center - Hydraulics, Engines, Electrical and More, has one with a tee handle in the middle of the barrell and a locking dog on one end. I just ordered one. A friend said that was the way to go. As far as I know no one else has one that short. Kubota is unique on that. I had bought a longer one but it wouldn't go short enough for some adjustments. My dealer says "what's wrong with a factory approved assembly"? He doesn't have to do this stuff in the mud, snow, snd rain.

The locking nut has always worked for me. But I do like the last method of fix. A quick and easy job with a peice of wire or something.

If they did not secure their catalog I would send you a copy, and if I could figure out to add attachments to this forum.
Mine will be here next week and I will post an opinion. Surplus Center is a great place to shop. Their Tech people are very helpful on the phone.

Is it possible this is a symptom of too much vibration, like maybe the PTO shaft is bent or out of balance, or a cross joint is badly worn?
Does the cylinder separate from the nut, or are both moving together? If they're moving together you could either use a locknut in place of the existing regular nut, or put a second nut on and jamb the two nuts together so they provide the resistance to turning. If the cylinder and nut are separating, then safety wiring would probably be the way to go.

If you dont adjust it often, what about using blue threadlock?

So you use the toplink for the side arm link? I am confused.
I don't use it often during operation of the equipment (like those that talk about continuously needing to adjust tilt for grading) but I use it when I hook/unhook, make occasional operating adjustments, etc. It doesn't matter which equipment I use it on (whether just being dragged like a grader box or mowing with PTO use) it will creep the same amount. I think the link has become looser as I use the tractor, most of the time with 3 pt mounted equipment (about 600 hours on tractor). The locking nut stays in one location and the adjuster cycles away from it. I had the same problem on an old tractor that had the crank handle type adjuster but that was easily fixed with a piece of twine holding the crank handle in place (you could tie it to the upper lift arm so the whole thing would raise/lower in unison). I would think the wire solution would twist itself on tight with the adjuster's rotational effort. I think I am going to try the lock washer next (never thought of that till someone suggested it) and see if that helps. I don't mind dragging out a reasonable side wrench to lock it in place but there is not place to use a regular wrench on the adjuster itself and it needs to be a pipe wrench to get a good grip. then with the pressure I must apply it will really start to mark the adjuster up....

My discussion was all about top link and that is what the part is far. I am looking into something similar for the side sway tutnbuckle as that is also a pain when you are down in the mud and snowand have to make a fine adjustment for the inplement being attached. On my BX25 that is a 1/2" pin connection each end to eliminate the turnbuckle and clevises. Any ideas out there. I now have quick hitch unit so that adjestment is more rare. Us old guys don't do well down on our knees even in the dry.
