Re: 9860 to 8010
Not technically true. You can drive (and even harvest) without a display installed, but you have no clue what your machine is doing. It would be like driving a car with no dashboard, idiot lights, etc.
Obviously you wouldn't want to harvest without a display, but it's nice to be able to at least move the machine without the display, if you've taken the display into the house for the winter, for example.
