Popis: Seven processor operations were investigated to examine the work environment of the processor operator. The invisible objects in the visual field of four processors were the jib, head, instrument for measuring logs, wiper, and cabin. The operator looked mostly at “the head of the processor” during delimbing, bucking and arranging; “the delimbed tree-length log for bucking” during delimbing and bucking; “the bucked log” during bucking and arranging; and “the sides of the road” during moving and skidding. From the frequency of fixation for each fixated object, the instrument for measuring logs and the head was found to require the most attention. The height of three processors’ steps for “mounting and alighting” were higher than the optimum value (58 cm), obtained from an anthropometric investigation of forest machine operators. The levers and pedals of four processors were arranged at suitable positions, according to JIS guidelines.
