abstract
- Tests were carried out in Alentejo (Southern Portugal), with the objective of studying the influence of tree size and varieties in olive harvesting by vibration. A shaker manufactured in Portugal, mounted on a front loader of a four wheel drive tractor was used in the tests. The shaker requires a minimum of 30 kW and vibrates either the trunk, or the main branches. The results will be stated in terms of the percentage of olives harvested within the total yield, work rate and time of vibration per tree.
