The hollow tubular cutting head is driven into the ground with an operator's foot by placing weight on a foot support attached to the cutting head. A plunger disc attached to a rod within the tubular head is used to eject the thatch or core of earth from the interior of the cutting head when the cutting head is lifted from the ground. A first supple washer is provided on the plunger disc to move with the plunger disc to wipe against the inside of the hollow cutting head to wipe the inside surface clean. A second supple washer is fixedly positioned inside the tubular body and is positioned to seal the interior of the tubular body from mud and moisture when the cutting tool is used to cut a plug of soil. Inside the tubular body and above the second supple washser is a spring attached to the plunger rod to normally bias the plunger rod in an upward position. | ||||||

| 76 | Rotary weed extractor | US793539 | 1985-10-31 | US4723802A | 1988-02-09 | David G. Fambrough |
| A rotary driven elongated pointed rod member having wingnut-like projections affixed thereto. The wingnut-like projections being spaced apart sufficient distances for contacting weeds and undesired plants at interval points when the device is moved beneath the surface of the ground while being rotated. The projections grip and wind the weed about the rod and then retain the weed and its roots and carry the unwanted wood and its root system out of the soil. The projections can depend straight downwardly or can be canted to form a spiral soil entering action. Following the withdrawal of the weed the loose soil that has been pulverized and aerated is left in the hole that had been formed by the weed removing action. | ||||||

| 78 | Lawn aerator | US041543 | 1979-05-23 | US4282943A | 1981-08-11 | Joseph Leitner |
| Disclosed herein is an aerator for use in providing cylindrical holes in a lawn or similar type surface so as to provide a nesting area for fertilizer and to allow the introduction of air beneath and along the root system of botanical life to be thus treated. The device comprises an elongate shaft from which emanates along the lower portion thereof a helical type of screw provided with shelf portions and a pointed extremity at the terminus of the shaft which is so constructed that the device not only cuts into the earth, but also carries the thus loosened dirt on the shelf portions so that when the device is removed from the hole a substantially cylindrical void is provided. | ||||||
| 79 | Lawn plugger | US45274374 | 1974-03-20 | US3927720A | 1975-12-23 | RAUCH ERWIN I |
| A lawn plugger includes a tubular body with a hollow punch attached to the lower end thereof. A foot is held slidably on the punch by a spring connected between the body and the foot. In use, the punch is thrust into the ground cutting out a plug and causing the foot to slide upwardly on the punch thereby compressing the spring. As a result, the spring urges the foot against the ground around the plug being removed and, at the same time, urges the plugger upwardly to assist in withdrawing the punch from the ground. As an incident to removing subsequent plugs from the ground, the prior plugs are forced upwardly through the punch and into the body by the new plugs. Within the body, a diverter directs the old plugs out through an opening in the side of the body.
