Abstract
A lawn comber or thatcher comprising a drum carrying a multiplicity of rows of radially extending tines extending from the surface of the drum, each row extending in a generally angular or helical path along the drum and being spaced such that at least one tine is always in contact with the ground to provide a driving force for the thatcher, each tine having a torsion or helical spring portion at a position adjacent the inner most end of each tine.
Claims15
An implement for removing material lying on the ground comprising a drum supported for rotation in a generally horizontal orientation, said drum carrying a multiplicity of rows of radially extending tines extending from the surface of the drum, each row extending in a generally angular or helical path along the drum, each row being so spaced from its adjacent row that at least one of said tines is substantially always in contact with the ground in use whereby the tines act as a driving mechanism for the implement, each tine being formed such that it is resiliently flexible intermediate its ends.
An attachement for an existing driven implement comprising a drum having a multiplicity of rows of radically extending tines extending from the surface of the drum, each row extending in a generally angular or helical path along the drum, each row being so spaced from its adjacent row such that in use one of said tines is substantially always in contact with the ground in use whereby the tines act as a driving mechanism for the implement, each tine being formed such that it is resiliently flexible intermediate its ends.
An implement for removing material lying on the ground comprising a support mounted for rotation in a generally horizontal orientation, said support carrying a multiplicity of tines extending therefrom, each tine comprising a length of spring wire formed with a spring loop portion adjacent one end of the tine, said support having a multiplicity of bores, each of which receives said one end of a tine, and a clamping means for engaging one end of said tines in said bores in a manner which deforms said one end to positively retain said tines in said bores.
