Beschreibung
Zusammenfassung:	A milling machine includes a cutting rotor accommodated in a rotor enclosure having side plates that are vertically adjustable with respect to a machine frame. To adjust the vertical elevation of the side plates, a plurality of sensors is mounted on the machine frame and associated with an electronic controller that measures and processes the vertical distance between the side plates and work surface. The electronic controller operates a hydraulic system to adjust the vertical distance between the side plates and the work surface. To accommodate changes in work surface topography, the hydraulic system includes a float circuit with an accumulator.
