The paper aims to point out the characteristics of a new pick-up type harvesting machine used in hazelnuts cultivation, the dust emission in the air and the productivity of mechanized harvesting operation. The paper reports the results of a first trial in the field. The prototype "Semek 900", manufactured by FACMA s.r.l., uses a mechanical harvesting pick up and it was tested in hazelnuts cultivation. The hazelnut fruits present on the ground had been previously moved in windrows using a hand blower. Work time measurements in according to the C.I.O.S.T.A. method. Each sample of harvested hazelnut was analyzed to measure the presence of shell damages and impurities. The environmental monitoring of dust was carried out both in ambient air and close to the machine driver. The dust samples were analyzed for the mass concentration and chemical composition of inorganic species. Therefore a theoretical working capacity was obtained with an operating efficiency level of 71%. The harvesting losses referred to the product in the windrows were 20% of the total production. The average concentration of dust was 7.5 mg m-3 in ambient air and 38.6 mg m-3 close to the machine driver. Most of the dust consisted in organics and soil components. The concentration of dust appears similar to that produced by other existing machines and therefore other solutions have to be studied.
