Abstract: Apparatus for automatic harvesting of fruit such as olives, nuts, almonds and/or the like, including a vibrating device provided with a pair of driven wheels with eccentric masses and driving pulleys adapted to rotate independently the wheels. The pulleys are actuated by means of a pair of substantially vertically opposed hydraulic motors fixed to the frame of the apparatus. The pulleys cooperate operatively with said driven wheels to produce vibrations of a frequency variable through an angle of substantially 360.degree.. Fixing articulated means for the jaw members act to tighten and shake the trunk of a tree and provide an autocentering couple. A catching member is associated to the jaws.
