<p>BFN 6611 HAND OPERATED SEED PLANTER A hand held seed planter includes a tubular body and a pair of ground-opening jaws pivotally carried on one end of the body. A seed hopper is slidably mounted on the other end of the body and a ground engaging collar is carried on the one end, surrounding the jaws and mounted for sliding movement on the tubular body. When the soil collar is placed on the ground and a downward force applied to the handle attached to the hopper, the jaws are moved downward into the soil and create a seed opening in the soil. Adjustable pins on the collar control the depth of the opening. At the same time, a seed scoop recess, carrying a seed, is brought into alignment with an opening in a tube which extends through the hopper. A seed is then transferred into the tube, passing through the tubular body and between the jaws, to be planted in the seed opening. In one embodiment of the invention, the jaws are operated by upward movement of the soil collar, while in another embodiment, the jaws are operated by rollers carried on an internal jaw actuating tube which contacts cams formed in the inside surfaces of the jaws.</p> |
