An apparatus for harvesting small fruits, in particular olives, almonds, pistachios and similar fruits, said apparatus comprising: - a handle portion (6,6a,6b) at which a user is arranged to grasp a manoeuvring pole of said apparatus; - a support body; - a first and a second oscillating comb-like member (20a,20b) pivotally connected to said support body at respective fulcrum points (23a,23b), said first and second oscillating comb-like members (20a,20b) being positioned side by side and comprising, respectively, a first and a second elongated base portion (30a,30b) provided, respectively, with a first and a second plurality of rods (35a,35b); - a motor group operatively connected to said first and second oscillating comb-like members (20a,20b) by a motion transmission group, said motion transmission group comprising: - a first connecting rod member having a first end pivotally connected to an end portion of said first elongated base portion and a second end arranged to connect said first connecting rod member to a crank group operatively connected to said motor group and provided with an eccentric pivot arranged to pivotally engage in an engagement hole provided at said second end of said first connecting rod member; - a second connecting rod member having a first end pivotally connected to an end portion of said second elongated base portion and a second end pivotally connected to said first connecting rod member at a point of said first connecting rod member positioned between said first and second end (62a,63a); said apparatus being characterized in that said motor group comprises a motor shaft on which a pinion is mounted arranged to directly mesh with a toothed wheel of said crank group to transmit the motion to said first oscillating comb-like member by said first connecting rod member, and to said second oscillating comb-like member by said second connecting rod member pivotally connected to said first connecting rod member in that said crank group comprises a first part and a second part fixed at opposite sides to said toothed wheel, said first part being provided with said eccentric pivot in that said first part is connected to said second part of said crank group at respective flange portions (77a,77b) and in that at least said first part is configured to form a closed body. - a handle portion (6,6a,6b) at which a user is arranged to grasp a manoeuvring pole of said apparatus; - a support body; - a first and a second oscillating comb-like member (20a,20b) pivotally connected to said support body at respective fulcrum points (23a,23b), said first and second oscillating comb-like members (20a,20b) being positioned side by side and comprising, respectively, a first and a second elongated base portion (30a,30b) provided, respectively, with a first and a second plurality of rods (35a,35b); - a motor group operatively connected to said first and second oscillating comb-like members (20a,20b) by a motion transmission group, said motion transmission group comprising: - a first connecting rod member having a first end pivotally connected to an end portion of said first elongated base portion and a second end arranged to connect said first connecting rod member to a crank group operatively connected to said motor group and provided with an eccentric pivot arranged to pivotally engage in an engagement hole provided at said second end of said first connecting rod member; - a second connecting rod member having a first end pivotally connected to an end portion of said second elongated base portion and a second end pivotally connected to said first connecting rod member at a point of said first connecting rod member positioned between said first and second end (62a,63a); said apparatus being characterized in that said motor group comprises a motor shaft on which a pinion is mounted arranged to directly mesh with a toothed wheel of said crank group to transmit the motion to said first oscillating comb-like member by said first connecting rod member, and to said second oscillating comb-like member by said second connecting rod member pivotally connected to said first connecting rod member in that said crank group comprises a first part and a second part fixed at opposite sides to said toothed wheel, said first part being provided with said eccentric pivot in that said first part is connected to said second part of said crank group at respective flange portions (77a,77b) and in that at least said first part is configured to form a closed body. - a first connecting rod member having a first end pivotally connected to an end portion of said first elongated base portion and a second end arranged to connect said first connecting rod member to a crank group operatively connected to said motor group and provided with an eccentric pivot arranged to pivotally engage in an engagement hole provided at said second end of said first connecting rod member; - a second connecting rod member having a first end pivotally connected to an end portion of said second elongated base portion and a second end pivotally connected to said first connecting rod member at a point of said first connecting rod member positioned between said first and second end (62a,63a);
