Grimme moves the HMI for changing the nominal values of the 80 most important harvesting parameters from the driver terminal(s) to an extra piece of hardware – called ErgoDrive. Four rotary knobs next to a small display enable the driver to change the nominal values of the 80 most important harvesting parameters.
As the driver looks at the display at a flat angle, he will probably have difficulties to see anything on the display. He must either memorise which of the four knobs does what or bent forward. Is this really more ergonomic and easier to use than showing the direct-access parameters on the terminal screen and changing them through a special rotary knob?
Another thing is clear: Moving software functionality into dedicated hardware is certainly more expensive or less economic for the customer.
