Abstract
Abstract This invention relates to soil penetrating implements of the kind for removing soil plugs of earth for the purpose of aerating, watering and fertilizing the soil or for any other agricultural purpose of treating the subsurface, and the particular improvement resides in the manufacture assembly, repair and operation of the several parts of the implement in a more efficient manner. The features are accomplished by, clamping the flexible steel ground engaging rim with its coring elements around separate spaced apart parallel wheel supports which are loosely mounted on a shaft journaled in a frame which may be coupled to a tractor and raised or lowered by the tractor hydraulic mechanism.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
214 words
A soil penetrating and coring implement adapted to be connected to and pulled over the ground surface by a tractor and including means connecting said tractor and said implement for transferring a portion of the weight of the tractor to the implement, said implement comprising, an axle and a frame connecting said axle to the rear of said tractor, a cylindrical member rotatably mounted on said axle and freely rotatable with respect thereto whereby as said tractor is moved said cylindrical member rolls along the ground surface behind said tractor, a plurality of hollow soil coring elements mounted to said cylindrical member whereby as a portion of the weight of said tractor is transferred to said cylindrical member and said cylindrical member is pulled along the ground surface by the tractor said coring elements penetrate the ground surface and remove a plug of soil therefrom, said weight transferring means comprising hydraulic means connected with said tractor and having an arm rotatable about an axis between an up position and a down position, said hydraulic means being operable when actuated to move said arm from said down position to said up position and means connected between said arm and said implement and translating upward force on said arm to a downward force on said implement.

Claim 3
Dependent Claim
69 words
The combination as defined in claim 1 and in which said cylindrical member comprises a pair of spaced apart wheels freely rotatable on said axle, a flexible spring steel band rim clamped to the periphery of both of said wheels to hold them in spaced relation, a plurality of spaced apart elongated openings formed in the surface of said rim and said core elements pivotally mounted in said openings.
Claim 4
Dependent Claim
37 words
The implement as defined in claim 1 and in which said connecting means comprises a chain connecting said arm to the underside of said frame and a sprocket engaging said chain intermediate said arm and said frame.
Claim 5
Dependent Claim
16 words
The combination as defined in claim 3 and including spring means for urging said frame upwardly.
Claim 6
Dependent Claim
27 words
Apparatus of the character described in claim 1 including means for positively preventing lateral movement of said elements relative to said elongated opening in said steel rim.
