Whole body vibrations during field operations in the vineyard

Human exposure to mechanical vibration can be a significant risk factor for exposed workers and this also occurs in the agricultural sector, in particular with reference to the driver of the tractor during field operations. The aim of this paper is the evaluation of Whole Body Vibrations for the operator driving tractors during the field operations in the vineyard. The experimental tests were performed using a wheeled and a track-laying tractor. They were coupled to four different machines: rototilling (RT), chisel plough (CP), flail mowers (FM) and vibro farmer (VF). Two homogeneous plots of vineyard, about 200 m long, were identified different only for slope: 0% and 30%. The tests were pe…

Evaluation of hand-arm vibrations during the use of portable olives harvesters

The use of portable shakers in olives harvesting is becoming increasingly, especially in Sicily, both to reduce the costs of production and to assure the oil quality. Nevertheless, it’s well known that the use of such tools may involve risk of exposure to hand-transmitted vibration. Such exposure to vibrations is a potential cause of muscular/skeletal pains in hand–arm system, and specific pathologies such as Vibration-Induced White Finger (VWF) and Carpal Tunnel Syndrome (CTS), Hand–Arm Vibration Syndrome (HAVS). The aim of this study was to assess the level of exposure to hand-arm vibration of the operators during the use of portable shakers for olives harvesting. Two different commonly u…

Soil management effect on soil penetration resistance in the vineyard

In environments characterized by steep slopes or arranged in terraces, among the shallow tillage systems, rototilling is extensively used. However, the effect of the repeated use of rototilling has a considerable influence on soil characteristics; it appears finely powdered, soft and without structure. In order to limit these inconveniences, an innovative self-propelled machine equipped with working tools as a spade, to be used in steep slopes or arranged in terraces areas, was designed by the Mechanics Section of the SAF (Scienze Agrarie e Forestali) Department of the University of Palermo in cooperation with Agrotec company, Padua, Italy. The aim of this study is to compare the effects of…
