drooping hydraulic arm

[jam2004]

Each time after leveling the right hydraulic arm, it droops an inch or two. Then I tighten the turnbuckle to level it, cut grass for about an hour and it droops again. I have a Pat's Easy Attach mounted to it, but no other heavy implement. It seems to me that if there was a nut on the bottom as well as the top I could stop it from slipping down. Is there something I missing here?

Are you saying that your turnbuckle arm is unscrewing itself during use?

I've seen them with a lock nut.. and also with a clamp that holds the crank in place. Maybee you could rig a bunji cord to hold the crank?

Yep. It unscrews itself downward leaving the right arm significantly lower than the left. There is no nut below the turnbuckle to keep it from creeping down.

Jay,
Mine has the crank arm that locks into place and holds good. My center arm has the locknut though and was always getting loose and expaining the arm.
For me tightening the locknut more worked, i really have to tighten hard but does not come loose now. why don't you take out the threaded screw part and add a nut and tighten both then that should work also.
I do not have you exact same model so maybe someone else that has you're same setup will have better solution.

You only need a locknut on one side of the turnbuckle (adjuster). The ends of the threaded shafts are pinned to the lift arms and can't rotate. Since neither top nor bottom can move, the adjuster must be turning. Use two wrenches and make sure the locknut is jammed tight against the adjuster. Try marking everything with chalk or crayon and you'll be able to see exactly what's moving. This assumes there are no bending, stripped, etc. parts.

Harry C.,

I went out and checked just what you said and I noticed the threads are completely stripped off for about .5 inches where the turnbuckle slides down. The way it's designed, it looks like the only thing I can do is to replace the entire piece.

Jay, Which part is stripped? You can get the individual parts from Kubota. If it's one of the threaded rods (not the adjuster) you can probably unpin one end and by turning the adjuster, and rods independently, move it to an unstripped section. Screw one in and one out 'till you get on good threads. Then just hook it back up. Keep in mind, one end is left hand theads, the other is right hand.

tractorsmart.com used to provide free parts manual downloads and also provides pretty good prices on these parts.
I say this because you're probably gonna have to order the down link thats stripped.
Once you lock down the lock nut on the adjuster, it should stay good and tight at the same position you locked it at. The down link is probably stripped at the very spot that keeps the entire assembly square.
FYI, theres been a few folks that put adjustable downlinks on both sides so ordering just the adjustable down link is possible.
Good luck

The threads just below the lock nut and just above the turnbuckle appear to be stripped. It's about a .5 inch gap. I talmost looks as if the threads are stripped to the core.
