ABSTRACT:
A haymaking machine has a substantially horizontal main frame beam with lateral carriers which are pivotable upwardly and downwardly relative to the main beam. The pivots define horizontal axes and pivoting takes place between a working position in which the beam and carriers are substantially horizontally aligned, and an inoperative transport position in which the carriers are turned upwardly relative to the frame beam through 90.degree. or more. Breakage of, or other serious damage to the drive transmission to rotary rake members of the machine is prevented by drivingly connecting a rotary shaft within the main frame beam to the rotary shaft segments housed within the carrier by double universal couplings which still allow the shaft segments to be driven when they are inclined to the main beam at 90.degree. or more. Also, the carriers mount crop guides that can be pivoted about horizontal axes and/or displaced relative to the rake members so as to function during either tedding or swath forming. The carriers can mount latch pins that are engaged by respective latches on the main beam and the latches have recesses that prevent excessive pivoting as well as retain the carriers in transport position.
