Hello how long do the tractors keep on the average today??? given this thread–>http://www.motor-talk.de/…/…recker-an-hour-runter-t2301969.html I asked myself the question what do you calculate, because the models are today quite high-equipped high-tech machines with electronic and hydraulic stuffed up to the stop?? how many operating hours should be possible until the maintenance exceeds the value??? the old models last longer than the new ones? m fg Andy
