Claims6
A haymaking machine comprising at least two drums;
- a flexible skirt on the lower part of each drum;
- spaced collectors on the periphery of said drums;
- means located at least partially under the skirts of said drums for raising cut fodder plants into a zone located between the drums, and wherein each collector is curved and articulated on the periphery of its respective drum by means of a shaft so that each collector can be pivoted and stopped in two different positions, one for tedding in which its outer end is practically radial and the other for windrowing in which said collector is directed toward the direction opposite to the rotational direction of its respective drum and the diameter of its trajectory is reduced.
