  • Publication number: 20110186313
    Abstract: A dirt hole closer is attached to the front of a skid steer, or to a tractor, forklift, or the like and consists of a frame, a push blade, a left arm, and a right arm. The frame is removably attached to the lifting mechanism of the vehicle. The push blade, the left arm, and the right arm are attached to the frame and have coplanar lower edges. Both the left arm and the right arm can be manipulated, by means such as hydraulic actuators. The dirt hole closer provides a novel method of planting trees or setting posts or poles and utilizes both linear and angular motion to push excavated dirt into the annulus of hole surrounding the object being planted.
