There is no doubt that John Deere is trying to control maintenance information for their products. Why? They can say all they want about safety but it's all about the benjamins. Look at cars, how easy would it be to work on anything current without at least a code reader? Same thing. What fascinates me is that the best way to correct this is for users to quite buying JD equipment. But when you have a company that not only sells equipment but gloves, hats, shovels, and flashlights, AND PEOPLE BUY THEM, you no longer have company loyalty, you belong to a cult.
