I have a 9540 witch is the FWA equivalent. I have done over 5000 hrs and other than the air conditioning have not had an issue. Hang on, I had some selector problems under warrently. Common problem but would be fixed on any tractors with the same problem by now.
It have very honest power, rated 93.5 but is better as I pull a claas varient baler rated at min 100hp required.
The trans is the 18 speed with the torque multiplyer, 3 speed.
The 16 speed trans in the John Deer 2800 were troublesome.
