A tree-shaking apparatus includes a vibration mechanism of conventional design mounted on a movable, tilted frame support that serves to deflect falling harvest onto a conveyor and collection assembly, which is mounted on a separately movable frame support. The shaker assembly has a peaked configuration with grooves extending away from the peak and toward the shaker. A pair of upwardly inclined walls flank the peaked walls at their outer edges, preventing harvested material from rolling or bouncing off the sides of the frame. Uniting the two units are a series of cooperative, pivotable guides extending from each of the units. When extended during collection, the guides from the shaker assembly overlay the guides from the collection assembly, forming a substantially continuous downward path from the shaker assembly to the conveyor. At the completion of a collection cycle, when the units are to be moved to a different tree, the guides flip to a vertical or rearwardly inclined rest position that prevents them from shearing against the tree. The apparatus also includes a series of selectably engageable barrier projections along the front edge of the shaker assembly. When drawn into an upright position, the projections retain whatever harvest remains on the shaker assembly after shaking, and which would otherwise be lost as the shaker assembly moves to a new tree.
