JD 4300 HST
As the subject says the forward control rod broke right where it threads into the ball joint. I can just touch the bolt but I don't see any way to replace the rod without splitting the tractor as stated in the manual. Does anyone know of a way to replace the rod without splitting the tractor or is that the only way to get to it?
Thanks in advance for any and all help.

Would you post a photo of the rod showing the place where it broke.

Do you have the part number?

Or the section in the manual?

Is that control rod in this schematic? maybe key 50?

If you can hold that ball joint immobile then you can possibly drill out the broken part with a left hand drill. Using a left hand drill often will cause the part being drilled to unscrew. If you need a long drill and can't find one then a drill extension is easily made. I can tell you how to make an extension if you need me to.

Thanks for the idea, but that is the problem. The other ball joint is tucked up in the tunnel in a challenging spot. The manual calls for splitting and I don't see a way around it. Even if I could reach it with a drill extension there is no way to attach the new rod without unbolting the ball joint which is the real problem.

Well that sucked. It did indeed require splitting.
