Abstract
A coupler assembly for coupling a work tool to a work machine. The assembly includes a body, a first locking mechanism, and a second locking mechanism. The first locking mechanism is pivotable about a pivot from a first position to a second position and is configured to be coupled to the work tool in the first position and decoupled in the second position. The second locking mechanism includes a pin having a first end and a second end, a tab coupled to the pin proximate the second end, and a spring disposed between the first end and the second end. The second locking mechanism is axially and pivotably movable about an axis such that the second locking mechanism includes a locked position and an unlocked position. As the first locking mechanism moves from the second position to the first position, the second locking mechanism automatically moves to the locked position.
