A ditching implement especially adapted for the construction of irrigation ditches having flat bottoms and divergently inclined side walls. The implement includes a plow-like main frame having elongate wings diverging rearwardly from each other in a V-shaped configuration. A hitch frame for coupling the implement to a three-point tractor hitch is slidably mounted for forward and rearward movement to the main frame along the longitudinal center line of the main frame. When a hitch frame is located at its forward limit of movement relative to the main frame, the hydraulic cylinder of the three-point hitch is operable to tilt the implement into a transport position clear of the ground.
