Abstract
An aerating device adapted to be retrofit to existing household lawn mowers comprising a pair of wheels each having a plurality of tines extending therefrom for penetrating a lawn and removing therefrom a section of soil, thereby aerating the lawn. The tines are offset from the center of the wheel to utilize the rotational energy of the wheel and the weight of the lawn mower to penetrate the lawn without the application of additional force by the user. In this manner, a user can simultaneously cut his/her lawn and aerate the same.
Claims5
An aerating device for a conventional house-hold lawn mower for mowing a lawn on soil, wherein the conventional house-hold lawn mower has a weight, a plurality of wheel housings, a pair of front wheels connected by a front axle, and a pair of rear wheels connected by a rear axle, and wherein said device is for replacing at least one of the pair of front wheels of the conventional house-hold lawn mower and the pair of rear wheels of the conventional house-hold lawn mower, said device comprising:
- a) a wheel for replacing each wheel of at least one of the pair of front wheels of the conventional house-hold lawn mower and the pair of rear wheel of the conventional house-hold lawn mower;
- said wheel having rotational energy when rotated, a center, and a periphery with a shape being eccentric which causes said wheel to rise and fall as said wheel traverses the lawn;
- and
- b) a plurality of tines extending radially outwardly from said periphery of said wheel, offset from said center of said wheel which causes a pivot action of said plurality of tines during rotation of said wheel that together with the rise and fall of said wheel caused by said eccentric shape of said periphery of said wheel facilitates introduction and removal of the plurality of tines from the lawn and the soil by utilizing only said rotational energy of said wheel and the weight of the conventional house-hold lawn mower without application of any additional force by a user.
