Sažetak

In Italy, where conventional forests have a protective rather than productive purpose, some silvicultural operations as first and second thinning could be carried out in an economic way adopting systems based on small scale mechanization. Authors tested a system based on small scale mechanization for bunching and skidding operations, using an All Terrain Vehicle (ATV), a compact, agile and versatile vehicle that adapts well to dense and rather inaccessible forests, such as forests of artificial origin where no kind of intervention, particularly thinning, had ever been carried out. The vehicle was used for bunching, using an electric winch, and for skidding whole trees. The use of the ATV showed that it is a competitive vehicle with both traditional and cutting edge vehicles, performing a traction power average of 313 daN and PHS0 productivity variable from 1.20 to 3.05 td.m.h-1. Such figures confirm how in first thinning, on level ground but also on slopes (max 50%), over distances not exceeding 200 m, the ATV is a perfectly suitable vehicle. Furthermore, the impact of the vehicle on the ground and especially on the shallow soil horizons was negligible and had no effect on tree roots.
