It was an impressive machine. But it was too big to be usefull for us. We already run a 9000JD which is hardly used. We rather need more flexible machines like the JD8000, Fendt 900 or Claas Axion.
We didnt run it long enough to say something about reliability. It had a good driving comfort and pulled everyting we hang behind it. Engine and gearbox seemed fine, we had nothing to complain about...
But this impression alone isnt a reason to buy it.
Btw, it was a Xerion 4000. Nor the big 5000.
here the machine is mostly used by custom farmers. See what they do with it:
