ABSTRACT:
An improved coupling assembly and method of use are disclosed herein to include a tool carrier attached to a utility loader or other work vehicle and supporting a pin guide. A pin is supported upon the carrier by the pin guide and interacts with one or more cam surfaces supported by the carrier. During axial rotation of the pin, the cam surface transfers a force to the pin to assist in the extraction and/or retraction of the pin into the implement. In one embodiment, the pin has a user graspable handle which may be rotated and axially moved by an operator. A visual indication that the pin is not fully engaged with the implement is also provided. Additionally, a locking mechanism is provided which prevents a pin from disengagement with the implement.
