An agricultural seeding machine, includes a seed hopper, a first frame member carrying a drive shaft, a second frame member carrying a driven shaft, a coupler, and a flexible shaft. The first frame member and the second frame member are foldable relative to each other between a folded position and an unfolded operational position. The coupler includes a first coupler half associated with the drive shaft, and a second coupler half associated with the driven shaft. The second coupler half and the first coupler half are configured for automatic engagement and disengagement upon movement between the folded position and the unfolded position respectively. The flexible shaft interconnects the first coupler half with the drive shaft or the second coupler half with the driven shaft.
