Abstract: A mobile milling machine can be equipped with a liquid spray system to introduce a liquid spray into a rotor enclosure to reduce the temperature of a plurality of cutting tools disposed on a rotatable cutting rotor. The liquid spray system can be associated with one or more surface wetness sensors to estimate the wetness of the work surface after the milling operation. The wetness of the work surface can be used to adjust the spray quantity of the liquid spray introduced by the liquid spray system.

Abstract: A rotor position indication system for a milling machine is provided. The rotor position indication system includes a height-adjustable rotor having a plurality of cutting tools and a front impact point. During a cutting process, the rotor removes a layer from a ground surface creating a milled ground surface. The front impact point is a point on the ground surface where cutting will stop if the cutting process is terminated. Further, the rotor position indication system includes a light emitting device configured to emit a light signal. The light signal aligns with the front impact point and shows the front impact point.
