  • Patent number: 10233598
    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.
    Type: Grant

  • Publication number: 20160362852
    Abstract: A rotary mixer has a mixing chamber with a rotor to reclaim the work surface. The rotary mixer has a supply container located on the frame adjacent to the front end thereof. The supply container contains an additive for mixing with the reclaimed work surface. A transport assembly connects the supply container to a distribution assembly. The distribution assembly is located in front of the mixing chamber and receives the additive from the transport assembly and deposits the additive on the work surface.
