ABSTRACT:
The present invention is a lawn-aerating and weed-pulling apparatus for use in aerating the ground and removing weeds. The apparatus comprises a substantially horizontal foot plate having a first side and a second side. A coring mechanism and a resilient biasing mechanism is secured to the second side of the foot plate. When the resilient biasing mechanism is compressed and then released it urges the foot plate and the coring mechanism which is secured to it in a generally upward direction. Upon exertion of a generally downward force on the foot plate, the resilient biasing mechanism is compressed, allowing the coring mechanism to penetrate the ground. Upon release of the generally downward force on the foot plate, the resilient biasing mechanism urges the foot plate and the coring mechanism which is secured to it upward, away from the ground, thereby removing a core of ground with substantially reduced or diminished effort on the part of the user.
