MILLING ATTACHMENT WITH ADJUSTABLE COVER
A work machine (20) includes:a machine frame (24);an attachment mounting frame (38) on the machine frame (24);a milling attachment (22) configured to be mounted on the attachment mounting frame (38) so that the milling attachment (22) can be manipulated relative to the machine frame (24), the milling attachment (22) including a milling drum housing (52) and a milling drum (54) rotatably mounted about a milling drum axis (146) within the milling drum housing (52), the milling drum housing (52) being pivotably mounted on the attachment mounting frame (38) such that the milling attachment (22) is tiltable relative to the attachment mounting frame (38) about a tilt axis (144) extending perpendicular to the milling drum axis (146);a hydraulic tilt cylinder (148) configured to tilt the milling attachment (22) about the tilt axis (144);a hydraulic circuit (300) connected to the hydraulic tilt cylinder (148) and being operable in both an active tilt mode where hydraulic fluid under pressure is applied to the hydraulic tilt cylinder (148) to tilt the milling attachment (22), and a floating mode in which the hydraulic tilt cylinder (148) does not apply any tilting force to the milling attachment (22).A method of operating the milling attachment (22) a comprises steps of:(a) milling a ground surface (28) by rotating the milling drum (54); and(b) during the milling step switching the hydraulic circuit (300) between the active tilt mode and the floating mode.
