3pt Turnbuckles going loose

SCRich · Apr 27, 2008

I have a L3400 with abt 75 hours on it. Normally this has not been a problem but for some reason now after a few minutes of operation my turnbuckles go loose then widen up when using my rake and start rubbing up against the inside of the tires.

The locking nuts are tight but the buckles still loosen up and of course the rake does not work very well that loose not to mention it can't be good for the tires. Any idea how to resolve this ?

double nut the locking nuts

Simple fix, thanks I just don't think sometimes. But I also still wonder why this started happening all of the sudden, never had an issue before.

On my B7500 there were pins that went through holes on the threaded part where it screwed inside the turnbuckle. Once they were adjusted to the proper width and the pin in the hole the turnbuckle couldn't rotate. I would suspect that yours is the same. Have you lost the pins or forgotten to put them in the hole?

Nope.. my tractor did not come with any safety pins in the buckles or holes for them. I would suspect that double nuts would do much better in that case other than pins anyway. The double nuts would allow the buckle to be secured at any position while the pin idea is good it would still allow the nut to loosen to some degree.
