RT Journal Article SR Electronic A1 Honsa, Jan A1 Neruda, Jindřich T1 Analysis of factors of the quality of logs produced by harvesters JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 57 IS 5 SP 131 OP 140 DO 10.11118/actaun200957050131 UL https://acta.mendelu.cz/artkey/acu-200905-0015.php AB Increasing demands of the present society lead to an effort to rationalize logging operations in forest management. Therefore, multi-function logging machines are increasingly used in the course of timber harvesting. Nevertheless, the economic effectiveness of these machines is affected not only by their productivity or environmentally friendly operations but also the quality of performed work. It can be evaluated by the assessment of the quality of produced assortments. Decreasing quality of produced logs can result in the reduction of marketability and wood price. Thus, the aim of this paper is to determine some defects originating at the harvester production of assortments and specification of their potential causes.
