BACKGROUND: On a summer morning in the Southcentral U.S., an equipment operator was felling a natural pine stand with a feller-buncher. The terrain was level, and weather conditions were dry and sunny, with a light wind. There was a moderate level of underbrush in the timber stand.
BACKGROUND: On a clear, dry, summer day in the South, an equipment operator was moving a skidder from one end of an old, abandoned woodyard to another. The terrain was flat, and the skidder operator was following an existing, old road.
BACKGROUND: On a clear, summer afternoon in the Southeast, a skidder was pulling a knuckleboom loader along a narrow, level woods road, so the loader could be connected to a truck during moving operations.
