    Abstract: This invention is a mechanical harvesting device which uses a novel approach to cut stems on agricultural products such as apples. The device is comprised of a system including levers and a unique cutting blade profile which allows for directional transfer of force from the wrists and forearms to effectuate cutting. The device is designed so that the cutting of stems on agricultural products can be performed separately and autonomously by both arms, thus offering improvements in efficiency and safety over other harvesting practices where the cutting is performed using both hands together. Current improvements include revisions to the product interface and safety guide as well as new versions of the device, employing many of the same design elements but having as the main difference a powered motor to actuate the cutting sequence in place of levers. Future improvements include options for data generation using electronic signal processing to tabulate periodic count totals on harvested product.
