Is it just mine or do other Fendt owners of the newer type cabs have problems with Aircon. My old 2008 718 worked fine, nice and cold. But this new one just doesn't seem get cold. If temps over 20 outside I'm sweating inside. It's at dealer at moment for a check over but they can't seem find a problem but now told me newer cabs arnt as good. So why pay £120k for a tractor with rubbish Aircon. Even worse with newer cabs only having 1 door and no side windows. Just wondering if anyone else having trouble.
