John Deere is not constrained by the Moss Magnusson act. This act requires auto manufactures to make their vehicles available to be serviced by anyone. They have to provide documentation, tools, etc. to non-company businesses (at a cost of course). Look it up for more info.Maybe they've been talking to the John Deere people about HOW to screw people with their 'no individual repairs' contracts. The manufacturers are going insane with this, "If we don't have something new no one will buy our automobiles." Just a bunch of BS to pry money out of customers' pockets.
John Deere is fighting this law. They want to be able to have a strangle hold on their market.
