Skyline and grapple yarding, however, require more complex, and expensive equipment. A traditional high lead or gravity system will function with just two cables, a skidding line. As the names imply the skidding line is used to drag the logs in, and the haulback line is used to drag the skidding

The yarder itself is located on a landing, a flat area on top of the ridge that is being logged. After the trees are retrieved by the yarder, the limbs are bucked (removed) and the logs are then placed in piles awaiting transport.
