ABSTRACT:
An ergonomically designed earth perforating tool consisting of a rectangular top plane and a convexly bowed base from which protrudes a plurality of spikes or times. A length of strap or rope is attached to each short end of the rocking plane to assist user balance. When stood upon and rocked side to side the spikes on the underside of tool easily penetrate the earth and hundreds of small holes are made at one time for aeration purposes or for the introduction of seed, fertilizer, herbicides, or any other matter. The user's centered body weight enables maximum use of centrifugal force effectively eliminating most of the physical strain associated with manual earth perforation and puncturing tools.
