ours will do 7000 hours over 4 years , some have been bought as low houred second hand and run on longer
the jd engines gave head gasket problems teir 2 were good teir 3 was a disaster anything worked hard was looking for gead gasket at 3000hrs
the teir 4 on seem ok had an injector in 1 another 1 liked to regen the dpf 3 times a day till we took the power washer to it .
gear boxes generally been ok other than the odd solinoid and switchs . beveled washers in clutch packs had a tendancy to crack ,
jd would be having these engine issues plus they were having turbo problems as well . and mf would be having the same gearbox but both companies well establised where as claas kept on there dealers and a lot of the renault boys got the boot .
we did once have a ter 3 claas 640 cebis that i recon was put together by hungover apprentices using warranty returns
