An evaluation of the visual field of a tractor operator was analyzed from photographs taken by a camera with a fish-eye lens. The visual fields of 11 types of tractors were insufficient for tractor operators, judging from "Visibility Arrangements" by ISO/TC 127. The visibility of a solid angle suggested that the main objects of the field that were invisible to the front were cabins, bonnets, and exhaust pipes. The operator's eye fixation was analyzed from three types of tractor operators' eye movements by an eye camera in each of four phases of operating. The operators tend to concentrate their fixations close ahead and to the sides of the roads, crawler (or wheel) , obstacles on the site, winches of the tractors, skidded logs, choker men, and attached dozers (or shovels) . In cable skidding, the operators of two crawler-type tractors face just to the rear, Iooking at the winches, but a one wheel-type tractor operator faced to the right-rear, as if stopping in the bending position of the back part. When unloading at the landing, the operator of this wheel-type tractor and one of crawler-type tractors concentrated their attentions on the skidded logs and dozers (or shovels) , as their solid angles were small, but the other crawler-type tractor operator looked at them over the rim of the dozer. The results that the solid angles for dozers (or shovels) and crawlers (or wheels) are small in spite of the operators concentrating their fixations on them, are considered a serious problem.
