    Patent number: 11641793
    Abstract: A mowing machine has a cutterbar oriented transverse to a travel and working direction of the mowing machine and provided with first and second ends spaced apart from each other in longitudinal direction. First cutting members are rotatably mounted on a top side of the cutterbar and rotatably driven about a vertical axis by a drive assembly within the cutterbar. A joint and drive assembly is connected to the first end of the cutterbar. A lateral cutterbar section is connected to the joint and drive assembly and has a second cutting member driven by the joint and drive assembly. The joint and drive assembly has first and second holding elements mounted relative to each other such that pivoting of the lateral cutterbar section in a cutterbar plane of the cutterbar is enabled.
