A harvesting head utilized with or incorporated into a mechanical harvesting machine for harvesting crops. The harvesting head has a frame that attaches to a frame member of the harvesting machine. The frame defines a harvesting area sized to receive the canopy of a tree or vine and supports a picking assembly and a motion inducing mechanism. The picking assembly comprises a pair of sub-structures having a forward post member, rearward post member, a connecting member connecting the two posts and a plurality of curvilinear rods, which also interconnect the posts, that extend into the harvesting area. The motion inducing mechanism is connected to and pivots the posts of the picking assembly so as to rapidly move the rods forward and backward to engage the canopy and dislodge the crop therefrom. A conveying assembly conveys the crop to a bin.
