Abstract
In a haymaking machine having two staggered rotors with substantially vertical axes, the tine groups on the circumference of the rotors each comprise one or more fixed upper tines and one lower tine which can yield upwardly. Preferably, the number of tine groups of the forward rotor is one half the number of tine groups of the rearward rotor and there is a single, upwardly yielding tine between every two successive tine groups of the forward rotor. Preferably, the tines extend through slots in a closed cap.
