Stupid? I like the design. Keeps "casual observers" out.
Right... in an effort to make everything tool-less... you now need a "tool" to open the hood. Can I get a "Hey Yeah!" for the JD engineers?
Not that I agree with nanny state, however I think this "key needed" to open the hood is due to wanting to keep you from opening the hood with the engine running, the key needs to be removed from ignition to open the open the hood.
