Abstract
A machine for harvesting fruits, berries and the like, from fruit trees and bushes planted in rows, the machine comprising a straddling chassis capable of moving across a field, a shaker assembly mounted on the chassis and including at least one pair of elongated shaker members which extend generally in the longitudinal direction of the machine and which are spaced transversely from one another and situated respectively on opposite sides of the central fore-and-aft axis of the machine so as to define an active shaking zone. Each shaker member is formed by a rod of flexible material. The machine further comprises a control mechanism operatively connected to the rods to drive them synchronously with a reciprocating motion in a direction extending transversely relative to said fore-and-aft axis. Each rod comprises an internal cavity in the form of a cylindrical bore extending the full length of the rod in a manner such that the weight of the rod is reduced considerably while having only little influence on the rigidity of the rod whereby the resonance frequency of the rod is increased.
