<p>The running wheels (4) of the carriage frame (1-4) are arranged in the intermediate space between the pair of neighbouring swath circles (17,18) and the staggered pre-arranged swath circles (19,20). The running wheels may be directionally adjustable in known ways. The swath circles may be invertable in known ways in its rotary direction. The pairing of neighbouring swath circles may be slidable and firmly set in its spacing to one another, such that its pronged circulation tracks (25) may have a large swath assembly in a central region between its intersection or its spacing.</p> |
