Abstract
A work machine includes a machine frame, an attachment mounting frame, and a milling attachment. A hydraulic tilt cylinder is configured to tilt the milling attachment about a tilt axis relative to the attachment mounting frame. A hydraulic circuit is connected to the hydraulic tilt cylinder and is operable in both an active tilt mode where hydraulic fluid under pressure is applied to the hydraulic tilt cylinder to tilt the milling attachment, and a floating mode in which the hydraulic tilt cylinder does not apply any tilting force to the milling attachment, the hydraulic circuit being configured to be switchable between the active tilt mode and the floating mode during milling of a ground surface by rotating the milling drum.
