Additional information

it shows 95% shaking effectiveness, which however decreases along with tree size because horizontal and pendular branches are worse at transmitting vibrations than upright ones. There exist models where the machine has a big umbrella below it in order to gather in the falling fruits, the reason why it is also called a "harvester".
