  • Patent number: 4209903
    Abstract: A cutting device for trimming grass and removing soil and debris from around a sprinkler head. The device includes a shaft with a handle mounted at one end to permit the user to push down and turn the device at the same time. A tubular cutting member is mounted at the other end in combination with a foot stand for enabling the user to initially push the cutting member into the ground by standing thereon. A pair of projecting blades extend from the inner surface of the tubular member and are limited in length to permit passage of the sprinkler head therebetween. These blades are also slightly pitched to develop a digging action upon rotation of the device in the ground around the sprinkler head and attached pipe. After the device is inserted into the ground and appropriately rotated, it is withdrawn with the enclosed grass, soil and debris.
