Abstract
Because no manufacturing standards provide it, the major part of the tracklaying tractors sold before 1990 in Italy are not equipped with protective structures and safety belts. Nevertheless, some EC Directives provide that in a farm the highest safety level on the agricultural machinery should be assured. The fitting of protective structures on tracklaying used tractors is to be carefully evaluated, considering the technical validity of the different fastening systems, due to the high variability of the shape of the machine rear part. The trend of the used tracklaying tractor fleet consistency in Italy was ascertained in the period 1982-1998; 12 tractor models were then selected, representing 85-90 % of the total consistency. A four-posts protective structure was proposed, verifying its suitability as through a real strenght test (according to OECD code 8), as thanks to a dedicated software produced by the Spanish University of Navarra. For each of the 12 tractor models selected a suitable form will be created, in order to offer at a maximum extent the technical characteristics of the most suitable protective structure and 2-points anchorage safety belt possible solutions.Pubblicazioni consigliate
