A mower provides a frame intended to be implemented on a tractor, or to form a structure of a trailer. The mower provides a plurality of cutting units (6), at least six, generally disposed side by side, each cutting unit (6) comprising at least one roller (44) intended to roll on the ground. The mower provides a lift assembly linking the cutting units (6) to the frame and configured for articulating the cutting units (6) between a mowing position and a non-mowing position. In the mowing position, the lift assembly is configured for pressing the cutting units (6) against the ground in order to distribute, at least partially, the mower's weight on the ground via the rollers (44) of the cutting units (6). The mower provides lateral articulated beams (10) linking the cutting units (6). The beams (10) are foldable inwardly and forwardly.
