A study conducted by researchers from the Universities of Florence and Palermo, together with the CNR–IRET (National Research Council – Research Institute on Terrestrial Ecosystems), compared the performance of battery-powered chainsaws and professional petrol chainsaws from the Stihl brand under real operating conditions. Two Italian worksites served as test sites: a thinning operation in a Douglas fir stand in the Vallombrosa forest (Tuscany), and a clear-cut of Scots pine on the Montebello estate (Emilia-Romagna). Two experienced operators alternated daily between the two types of machines, allowing precise timed monitoring of working times, output, and consumption levels.
The results show operational equivalence between the two technologies: the net productivity levels recorded were comparable, and even higher for battery-powered saws on some days. Productivity is therefore not limited by the type of engine, but by stand conditions (diameter, density, accessibility). Economically, the initial investment in battery-powered equipment remains three to four times higher, owing to the fleet of batteries required to cover a full working day; however, the cost per unit of output falls at an intermediate level between standard fuel and two-stroke mix. The benefits in terms of reduced noise, vibration, and emissions remain decisive for use in sensitive or protected areas.
The authors conclude that electric power constitutes a realistic prospect for forestry operations, provided that battery life and weight are improved.
