A mowing device has an elongate frame with opposing longitudinal ends and two mowing units disposed on opposite longitudinal sides of the frame. Each mowing unit has an elongate support with a first pivot joint (G1) by which a first of the opposing longitudinal ends of the support is hinged on one of the longitudinal sides to pivot about a horizontal rotational axis (A) extending in the longitudinal direction (LR1) of the frame. A bar-shaped mower is hinged on a second the opposing longitudinal ends of the support in order to extend, in a working position, longitudinally horizontally and transversely to the longitudinal direction (LR1). A second pivot joint (G2) provides a rotational axis (A2) that extends vertically, transversely to the first rotational axis (A1) to allow for mower pivoting to a transport position.
