An operating assemblage to harvest agricultural crops at a peak of ripeness comprising a mobility component configured to navigate through an agricultural field at least one vacuum motor calibrated to generate necessary and sufficient suction to successfully harvest a harvestable ripe unit of a crop such as a fruit, berry, nut, or vegetable using a collection hose ending in a collection nozzle of a size appropriate to the crop the collection nozzle housing an array of sensors and a collection and storage receptacle for harvested produce. The assemblage is configured by an operator inputting parameters to calibrate the array of sensors to trigger the vacuum motor to apply sufficient suction to harvest agricultural produce at a specified degree of ripeness. Components of the operating assemblage are connected to a power source responsive to real time communication via an electronic device equipped with at least one Wi-Fi chip set or Bluetooth capability.
