ABSTRACT:
The apparatus consists of a shaft in vertical position, the upper portion attached to blade mounting pad under the engine of a power lawn mower. At the lowest end there is a circular disk with cutting teeth around the periphery. The cutting disk is suspended below the power lawn mower by the length of the shaft and with the mower in normal operating position the cutting disk is below ground level. When the mower with engine operating is pushed over a tree stump, the cutting disk is forced into the stump below ground level and cuts it off.
