Concrete finishing apparatus

A method for smoothing and leveling partially set-up concrete at a support surface, said method comprising:

• providing a concrete finishing apparatus having a first concrete working member and a second concrete working member, wherein said first concrete working member comprises a ring shaped member that has a circumferential concrete engaging surface for engaging the concrete surface substantially circumferentially around said first concrete working member during normal operation of said concrete finishing apparatus, and wherein said second concrete working member comprises at least one concrete engaging surface for engaging the concrete surface during normal operation of said concrete finishing apparatus;
• rotating said first concrete working member about a first axis of rotation to process the partially set-up concrete surface with said circumferential concrete engaging surface, wherein said first axis of rotation is generally vertical when said first concrete working member is supported at a generally horizontal support surface;
• and
• rotating said second concrete working member about a second axis of rotation to process the partially set-up concrete surface with said at least one concrete engaging surface, wherein said second axis of rotation is generally vertical when said second concrete working member is supported at a generally horizontal support surface.

A method for smoothing and leveling partially set-up concrete at a support surface, said method comprising:

• providing a concrete finishing apparatus having a first concrete working member and a second concrete working member, wherein said second concrete working member comprises an inner ring-shaped concrete working member and wherein said first concrete working member comprises an outer concrete working member disposed around a periphery of said second concrete working member;
• rotating said first concrete working member about a first axis of rotation to process the partially set-up concrete surface, wherein said first axis of rotation is generally vertical when said first concrete working member is supported at a generally horizontal support surface;
• and
• rotating said second concrete working member about a second axis of rotation to process the partially set-up concrete surface, wherein said second axis of rotation is generally vertical when said second concrete working member is supported at a generally horizontal support surface.

A concrete finishing apparatus for smoothing and leveling partially set-up concrete at a support surface, said concrete finishing apparatus comprising:

• a frame portion;
• a first concrete working member disposed at said frame portion and rotatable about a first axis of rotation that is generally vertical when said first concrete working member is supported at a generally horizontal support surface;
• a second concrete working member disposed at said frame portion and rotatable about a second axis of rotation that is generally vertical when said second concrete working member is supported at a generally horizontal support surface, wherein said second concrete working member comprises an inner ring-shaped concrete working member and wherein said first concrete working member comprises an outer generally ring-shaped concrete working member disposed around the periphery of said second concrete working member;
• and
• wherein said first and second concrete working members engage the partially set-up concrete surface at the support surface and rotate about said first and second axes of rotation to process the concrete surface.
