  • Patent number: 5871058
    Abstract: An apparatus for manually moving, turning, and loosening earth and soil and which is particularly adapted for turning and loosening soil in a garden. An interchangeable implement head, preferably a fork, is configured for penetrating the earth. The implement head is connected to a shaft which supports a handle. The shaft includes upper and lower segments with the upper segment being angled away from the user's body. Positioned adjacent to the implement head, and connected to the shaft, is a structure for receiving the foot of the user. The structure for receiving the foot of the user preferably surrounds the circumference of the foot and loosely holds the foot in position to allow the user to push downwardly with the foot so that the implement head penetrates the earth. A lever arm adapted for extending the fulcrum point for the implement away from the back side of the implement head provides the user additional mechanical advantage.
