Vibration parameters assessment to develop a continuous lateral canopy shaker for mechanical harvesting of traditional olive trees

The fruit harvesting is a key factor involving both product quality and profitability. Particularly, mechanical harvesting of traditional oil olive orchards is hint by tree training system for manual harvesting, tree size and several and slanted trunks which makes difficult trunk shaker work. Theref...
