The Pneumatic Tree Limb Shaker (also called a hook shaker) is designed to facilitate tree fruit and nut harvesting. The tool includes the hook shaker that screws into the end of a fixed-length (5-, 61/2-, or 8-foot) or a telescoping (2X) pole. To use, one puts the hook around a limb and squeezes the trigger on the pole. A violent shaking motion causes the fruit/nuts to dislodge and fall to the ground. (Requires portable air or inert gas compressor and hose.)
