Tbf when buying a 155, 50k doesn't come into the picture as they never came with it, air is rare and it's 05 model so a sauermann push out would've been out of the question unless you find one with it fitted after but I agree. Could find a good t6080 or t70 series in that price range and for what they are looking for it, makes timmins seem cheapBig enough price relative to paying a bit more and buying g a fresher lower houred tractor.
in practical terms
Has the old swing back hitch
The head would need doing on a preventative basis if not already done
And has 10,000 hours if being bought as a frontline tractor.
the above things are not a reason not to buy it but at €43k you are a lot of the way to something like a T7.200, loader aside.
