  • a frame;

    a ground engaging member adapted to interact with a road surface;

    a retracting vertical actuator system disposed between the frame and the ground engaging member to raise and lower the frame;

    a housing including a vertical wall movable relative to the frame and having a bottom edge that abuts the road surface, and a position detector configured to determine a relative vertical distance between the vertical wall and the frame;

    a drum enclosed within the housing and arranged to rotate about a drum axis, the drum is connected to the frame and configured to plane the road surface during operation;

    a spray bank disposed inside the housing arranged to spray a fluid directed at the drum; and

    a controller configured to automatically actuate fluid spray via the spray bank based on determining that the relative vertical distance is above a first threshold height value.
