Abstract: A method for releasing a trailer from a tractor is disclosed. A fifth wheel yanker moves a fifth wheel release handle in the sequence needed to operate the release handle in the sequence used by, for example, the Yost brand of fifth wheel Jost fifth wheel safety catch release mechanisms. A yanker hook on a yanker shaft is hooked to a release handle of the fifth wheel, then twisted counterclockwise to press a yanker lever against the tractor frame to move the release handle upward and leftward onto a fifth wheel shelf. The yanker is then pulled outward, releasing a trailer from the fifth wheel. Reaching deep under the trailer is avoided, and biomechanical strain is reduced.
