ABSTRACT
In the Czech Republic, harvester technologies represent the second most-frequently used technology. Demand for high efficiency in this type of technology is conditioned by the need to cover acquisition and operation costs. The aim of this study is to monitor operation time of a high-powered Ponsse Ergo harvester. Felling process in the course of salvage felling was analyzed with the help of continuous chronometry. The analysis was conducted for harvesting of spruce ranging from 0.05–2.00 m3/stem. Operation time consumption for the processing of a tree ranges from 62 s to 171 s in relation to the respective tree volume, which represents 0.02–0.24 h/m3 of operation time.
Key words: harvester, operation time, productivity.
