A novel mobile orchard platform and method of operation for preferably harvesting apples on trellised tress is introduced herein. An exemplary embodiment herein utilizes an articulated lifting arm which manipulates a catch frame and an apple harvesting attachment. The catch frame is configured with at least one but more often a multi-layer design of catch pans, which are inserted into the tree canopy wall lying under a trellised branch using the manipulating arm. An eccentric Dual Motor Actuator (DMA) coupled to support shafts is preferably utilized to provide shaker harmonic patterns and energy to one or more points on coupled trellis wires or one or more points of the branches of the trained trees residing in an orchard. The removed apples are caught using the catch pans.
