Abstract
A planting tool for plants comprises a tube having a fixed beak half at its lower end. A hinged beak is hinged to the tube such that the fixed and hinged beak halves together form a beak capable of being pressed into the ground. The beak is then opened to make a hole in the ground for the plant, and is latched in the open position by the drawbar of a latching mechanism. The drawbar is attached to the hinged beak half and arranged to slide along an outside surface of the tube as the beak is opened and closed. The drawbar slides within a protective rail that is affixed to the outside of the tube to avoid being damaged or obstructed. The upper end of the drawbar extends above a reference edge of the rail when the beak is closed, and extends below that edge when the beak is open, thereby providing a visual indication of the condition of the beak. A handle for lifting and aiming the tube is adjustably attached to the rail to be adjustable to the height of the operator.
