Abstract
A hay-making machine comprising motor-driven working members which rotate about upwardly orientated shafts. The working members are divided into three groups arranged in rows extending transversely to the direction of travel of the machine. A central group is at the rear of the machine and two outboard groups extend outwardly from a location forward of the central rear group in such a manner that the inner working member of each outboard group overlaps (as seen in the direction of travel) the outer working member of the central rear group. The machine includes a frame on which the three groups of working members are mounted. Each group includes four working members. The outer two working members of the outboard groups are foldable to a position over the two inner working members of each of these groups about horizontal axes. Then the outboard groups, as so folded, can be pivoted about vertical axes so that they are positioned along side the frame. The outer working members of the central rear group can be pivoted about horizontal axes extending in the direction of travel of the machine by ninety degrees whereby the machine, in its transport position, is less than about three meters in width compared to its working width of about twelve meters in width.
