Abstract: A system and method of raising and lowering a ball coupler for coupling to a ball hitch is provided. A combination of hydraulic pump and hydraulic piston are employed to raise and lower the ball coupler of a gooseneck trailer. Both custom and off the shelf parts combine to create a user friendly system to couple and uncouple a gooseneck trailer to the truck.

Varying trailer frame configurations and ball coupler sizes can be employed with the present invention. Also described and shown in this provisional is a non-rotating free end hydraulic piston device and method. Also described and shown is a coupling bushing device and method for securing a conventional coupler to piston rod.
