FIELD: agriculture.SUBSTANCE: machine comprises hingedly coupled sections of frames with working tools arranged serially along its length. Frame sections are connected with a mechanism for transfer into a transport position, for instance, with a hydraulic cylinder. The hinged connection of frame sections is made in the form of a longitudinal slot in cheeks of one frame and a finger of another frame arranged in it. In the working position frame sections are additionally coupled by means of a movable joint placed in front of the hinged one and made in the form of an open longitudinal slot in cheeks of one frame and a finger of another frame installed in it. The length of the slot of the movable joint is less than the length of the slot of the hinged joint by the value exceeding the width of the slot of the movable joint.EFFECT: invention will make it possible to simplify transfer of a machine with serial multi-row arrangement of frame sections with working tools from a working position into a transport one and to exclude manual fixation of frames.2 cl, 4 dwg |
