Abstract
A milling machine includes a frame carrying a rotatably-mounted drum in a drum enclosure, a primary reservoir, a pump fluidly associated with the primary reservoir and at least one auxiliary reservoir. The primary reservoir includes at least one fill port and is configured to receive fluid to be enclosed within the primary reservoir. The auxiliary reservoir is removably coupled to the frame, and includes at least one auxiliary air vent opening disposed in an upper portion. The air vent opening permits the passage of air as the auxiliary reservoir is filled and drained. At least one fluid connection fluidly coupled to a lower portion of the auxiliary reservoir fluidly couples the auxiliary reservoir to the primary reservoir. The primary reservoir and the at least one auxiliary reservoir are configured to equilibrate as the pump draws fluid from the primary reservoir.
