Can you bend it back, straight enough to get the work at your son's place done and until you can get the stabilizer bars?
I've had turnbuckles on side & toplinks "undo" themselves, just from the gentle vibration of the tractor. It has caused some embarrassing moments. As a result, I've got into the habit of socking them up good & tight with a wrench.
The stabilizer bars have been a huge improvement on our
B2320 and the
B5100.
They replace the check chains / sway turnbuckles, not the turnbuckle lifting links.
You might take a look at the crank adjustable lift links, since you're in the market.
I've seen them on some older tractors and I think AgriSupply carries them, too ...
Mark Hodge, of Stabilworks, made both and I highly recommend him, if he's still in business.
Well, just crud! I set the finishing mower off today so I could use the box blade on the L2501 with 30 hours on it now. I started backing up to the box blade and felt some resistance, so I stopped and got off to look. The adjustable thing that sets the height of the right side lift arm had come off at the top. I don't know how in the @*^$ that could happen? The hitch pin had dropped off and the ball end just slipped off the pin and fell down and of course when I started backing up it bent the you know what out of the turnbuckle on that side.
