I have a 790 4 Wheel Drive. At 150 hours all of the gears in the right side of the front axle shattered. After the dealer replaced these, 20 hours later all of the gears in the left side did the same thing. The dealer said that they checked the left side when the replaced the gears in the right side and didn't see any problems. They are claiming that JD has had some quality control issues with the heat treating of the gears. I found another string on TBN that several other people had the same problem. One of them was at about 57 hours and another at 130 hours.
The Dealer replaced the gears on warranty but is telling me that JD is still asking questions and trying to blame the problem on something else. I sent him a copy of the previous thread.
Needless to say, I am very disappointed with JD and the dealer for not replacing all of the gears at the same time and saving me the additional loss. It cost me about $800 in fuel just to deliver and pick-up the tractor both times. The dealer says that's my problem.
