MF 6290 - electronic linkage gone feral

Hi All, MF6290 2001.
The linkage sometimes suddenly starts raising and lowering by itself. It can be a bit scary when it does it while you're on the road and suddenly the implement starts bouncing violently up and down making the tractor bounce wildly, and it drops the tedder onto the tarmac!

Has anyone had that happen and knows what it is?

I do have a residual 3-6 fault on the ELC, which I believe is the intermix potentiometer and classed as non-serious.

Thanks in advance.

I had a 3070 that did that. the cause was the draft sensing lower pin that had become loose enough to damage the wiring from it.

Turn the dials to position control and minimum sensitivity, sounds like the draft sensors. You can also disconnect them to see if it makes a difference.

As said hyd cross shaft moving side to side is another thing to check.

Thanks for the replies. Can the lower link sensors or the cross shaft position detector be tested using the plug-in diagnostic software?
Is there any other way to test them?
