A haymaking machine comprising at least one rotatably mounted rotor assembly a plurality of tine assemblies pivotally mounted on the rotor assembly eccentrically of the rotational axis thereof, linkage means coaxially mounted at one end on the tine assemblies and pivotable relative thereto, and to the rotor assembly, actuation means on the rotor assembly, and connecting means extending between the actuation means and the linkage means, the linkage means being connectible in at least one operating condition to the tine assemblies so as to be movable in unison therewith, the arrangement being such that in that operating condition the actuation means cause the tine assemblies to pivot from extended, crop-engaging positions to retracted, crop-releasing positions and vice versa.
