As far as I am aware Fendts are probably the Rolls Royce of tractors. That said, I would be asking "why has this tractor had a recon: at 7000hrs?" It should easily have gone 10000 hrs on normal use.
PS. My brother in law has just arrived. He has been driving Fendts for years. (He has also been drinkng for years). His first Fendt was a brand new 312; it was a first class tractor, and is still in the team. He is now on his fifth Fendt. The 312 has never had an overhaul. It has around 20000 hours on the clock of which half were spent operating a four metre power-harrow-combination drill.
This tractor is one of four 312's acquired at that time. All of which are in their mid teens; about 13000 to 15000 hrs without problems. They are all doing heavy pto work.
PPS. He doesn't drink much, really.
