Abstract
The objective of the present work was to compare two types of grape harvesting machines, one using horizontal shaking (SO) and another using vertical shaking (SV). The trials were carried out on Trebbiano Romagnolo cultivar trained by Casarsa and GDC system.
During the trials the extent of the vibrations transferred from the shaker on the effects on the products, on the plants and the final features of the wine were evaluated.
The results have shown differences between the two grape harvesting machines and to a lesser extent between the adjustments used with each machine.
The extent and the duration of the vibrations transmitted have affected the mistreatment of the vines, the harvest characteristics and the results of the enological transformation.
The vertical shaking system has allowed a better overall performance due to a closer interaction between the plant and the machine.
