Nut-Shaker - S1.E11

1997 F-150 Ford Pickup Truck / Tree-Shaker No, this machine shakes nuts (and fruit) from trees. Using a hydraulically powered clamp and rotating mass device, this harvesting device latches onto a tree, shakes vigorously, then collects the falling nuts in an umbrella — all without damaging the tree. Able to shake up to three trees a minute, this machine has revolutionized the agricultural industry.
