Cleaning works in Croatian forestry are performed with chainsaws (so-called silvicultural chainsaws) and simple hand tools (billhook, machete, sickle). Cleaning of a young stand is work that causes great physical strain on workers. Working conditions are extremely unfavorable (work with dangerous tools, dense vegetation, insects, high temperature and humidity, bending). With the development of battery technology and the increase of energy autonomy, tools that can be used in cleaning works are increasingly appearing on the market. This research seeks to determine first of all the ergonomic, and then the energetic and economic suitability of battery tools in the cleaning of the even-aged stands. The ergonomic assessment methods used are based on recording the effective work using a video camera, measuring the vibration levels on the observed tools, measuring the heart rate of workers, and assessing body position. For energetic and economic assessment energy consumption and performance were recorded. An unmanned aerial vehicle was also used for the purpose of visual control of the execution of works. The results of the research confirm that the daily exposure to vibrations is lower when working with battery tools compared to conventional equivalents. Physical load is less in both earlier and later cleaning when working with battery tools compared to conventional tools. REBA assessment of postural load when working with the observed tools showed that battery chainsaws cause higher postural load than regular chainsaws, while battery shears cause less postural load than hand tools. Battery chainsaw requires less energy than a regular chainsaw, and costs are also lower when working with a battery chainsaw. The performance difference between battery shears and hand tools is less than 10 %, while performance difference between battery chainsaw and regular chainsaw is greater than 10 %. Orthophoto images of the site taken by the drone on three occasions enabled visual control of the execution of works. Theresults of the research are intended to better understand the techniques and methods used in cleaning works, the problems that arise, and potential solutions and improvements.
