(57) A chute rotation system (112). The chute rotation system includes a chute (105), a handle assembly (115), and a drive assembly (135). The handle assembly includes a handle rotatable about a first axis and a second axis, and a bracket configured to inhibit movement of the handle about the first axis. The drive assembly (135) is coupled to the handle assembly (115) and includes a chute drive, a transverse gear, and a friction brake. The brake is configured to prevent movement of the chute (105), as a result of friction, when the friction -brake is engaged with the chute drive.
