  • Patent number: 4932339
    Abstract: A bulb and bedding planter for the manual planting of bulbs, seedlings, and bedding plants in soil, comprising an elongated hollow tube with a handle at its upper end, and a substantially enclosed hollow plunger enclosure attached to the other end. The lower end of the enclosure terminates in a tip adapted to easily penetrate the soil; its upper end extends laterally, terminating in flanges which provide a foot rest for the operator. An elongated rod with a plunger handle at its upper end and a plunger at its lower end is slidably contained within said tube. Both the plunger handle and the plunger are of diameter slightly larger than the interior of said tube, thus limiting the motion of the rod within the tube. The planter can be used rapidly and efficiently by a standing operator, thereby reducing the bending and kneeling usually associated with this activity.
