【 摘 要 】

This study deal with the productivity of felling-bunching machine for differently aged forest when using conventional logging heads (CH) and multiple-tree accumulating head (AH). Experimental studies of logging technological processes using AH and CH-based felling-bunching machine were carries out for harvesting of large-sized and thin tree. We used total number of thin and large-sized trees in the working zone, 6..10 and 1..5 trees, respectively, and the average volume of thin and large-sized tree stick, 0.0042..0.096 and 0.26..2.26 m3, respectively, as independent variables. It is shown that the felling-bunching machine productivity per shift increases with the number of trees within the working zone. At the same time, with increase of total number of trees within the working zone, the productivity decreases. The highest productivity of the machine is in the harvesting only large-sized trees. In practice, it is possible to recommend joint harvesting of large-sized and thin trees, when the average volume of the large-sized tree stick does not exceed the two volumes of thin trees.
