摘要

The rake (1) has a frame (3) harnessed with a tractor (2) and provided with vertical legs (32). The frame carries a horizontal rotor (4) placed transversely at a specific angle, where the rotor has a helical profile. The rotor has a shaft (40) that is provided with a set of teeth (41) in radial directions or directions radial to an axis of the shaft. The teeth are attached to the shaft by fixation units e.g. flanges (42), that become partially inactive under the effect of torque, with a predetermined value, exerted on the teeth for permitting retraction of the teeth.
