Abstract
In a cold planer, a rotor housing partially enclosing a rotor may have a rotor housing side wall with retention plates defining a space in which a rotor housing side plate disposed so that the side plate can translate and rotate relative to the rotor housing. A pair of side plate lift cylinders may operate to vary a vertical position of the rotor housing side plate and a rotation of the rotor housing side plate about a horizontal axis relative to the rotor housing. The cold planer may use information from one or more distance sensors to identify contours in a work surface over which the cold planer is propelled, and actuate the lift cylinders to adjust the position and orientation of the rotor housing side plate to closely track the contour of the work surface and substantially prevent ground material from escaping from the rotor housing.
