A turf slicer includes a gang of six slicer wheels that "walk" through the turf in response to the forward motion of the turf slicer. In the meantime, the power takeoff from the tractor vertically oscillates the slicer wheels out of phase with one another, so that every sixth wheel is being thrust downwardly to bear most of the weight of the turf slicer as the other five wheels in the gang of six are either being withdrawn upwardly or moved downwardly and do not bear much weight, so that the weight of the turf slicer is concentrated on the downwardly moving slicer wheel that is approaching bottom dead center of its movement, thereby amplifying the effective weight of the turf slicer against the turf below.
