robexel:All the problems you mention seem to be transmission related. It sounds to me like bad driving, or at least operating with excessive speed. If you're going to push a machine to its limits, you have to expect this type of wear.
The only alternative I can suggest is a Unimog, they are the only "tractor" built for road work, and will work well on grassland ops too.
hmmmm where to start??? we have just got rid of a 6920, 55plate, in its time we have had 3 lots of brakes, a new radiator and all sorts of capers, bad driving NO.
At first it was the at 431 hours then at 1200 then it had a break until 4000hrs. At first it was under warranty but the 2nd time which was 6 months later the leader demanded John Deere themselves come out as the local dealer tried to bill us, in the end we went 50/50.
The last time we refused to pay and as we have a new tractor every year we told JD we was going back to Case unless they played ball, what they did was as it was a 40km unit put a brake server for the trailer brakes that was standard on the 50km units therefore the trailers brakes would pull the tractor back too and replaced all the warped brake system. All our trailers are 3 years or less Bailey trailers with dam good brakes. Some are 14ton others 16 tonners so we know its not them.
The first thing we noticed was the oil (transmission) going black and overheating then stop lights, then complete drive loss, this was when it went in, the 2nd time again the sightglass was going black, this time JD replaced the radiator as they said it was faulty (privately saying there was a design fault) as although it was cooling the engine it was not cooling the hyd/trans oil down and to quote JD cooking the oil and therefore lose all its protective properties and allow the brake and transmission systems to fail.
Before the tractor went again we swapped it in for a 6930 in november.
Although JD did come good in the end, they were very reluctant and when threatened with future sales they played ball. Bad driving NO
I'm tired of political jokes, ive seen too many of them get elected....
