The device comprises a transverse frame member having depending border disc mounts. The transverse frame member also has a hitch extending forwardly therefrom for attachment to a three point hitch on a tractor. The water stop attachment has a ladder type framework with one side of the ladder frame pivotally attached to the border disc transverse frame member. A spaced parallel frame member of the ladder frame is attached to a plurality of stop plates which are located directly behind the depending border disc mounts. A single hydraulic cylinder extends between a raised portion of the three point hitch and a central member of the ladder frame for raising and lowering the stop mechanism upon actuation of a hydraulic switch or valve located in the cab of the tow vehicle.
