ABSTRACT:
This invention provides a planting apparatus which includes a mobile frame mounted on wheels or the like and adapted to be towed over the ground. An arm is swingably mounted to the frame and extends rearwardly from the mounting location. The arm carries a dibble on its moveable end, which is adapted to cut into the ground during forward travel of the mobile frame. A planter is carried by the arm rearwardly of the dibble and is adapted to support a seedling for planting in the cut made by the dibble. Means is provided to dislodge the seedling from the planter into the cut. Detection means is provided for detecting when the dibble has cut to a predetermined depth into the ground, and for activating the dislodging means whenever that depth is reached. The arm is swung regularly toward and away from the ground, such that the dislodging means fails to operate if the dibble achieves less than the pre-determined depth due to an obstacle. Thus seedlings are planted only where no obstacles are located.
