A convertible yard tool is disclosed having an implement connected for rotation within a housing, wherein the implement and housing are operated relative to a ground surface in either a snow throwing orientation or a sweeping orientation. When operated in the snow throwing orientation and with the implement being a snow throwing impeller, the yard tool can be used to remove snow from a surface. When operated in the sweeping orientation and with the implement being a broom, the yard tool can be used to move debris from a surface to be cleaned. An adjustable handle may be provided to facilitate movement of the yard tool across various surfaces.

What is claimed is: 1. A convertible yard tool assembly comprising: a rotatable snow impeller; a rotatable sweeping broom; a housing defining a compartment, said housing being supported upon a ground surface in at least two operational orientations, wherein with said housing in one operational orientation and said snow impeller rotating within the compartment, the yard tool performs a snow throwing operation by moving snow initially rearwardly relative to a direction of forward machine motion toward a rear portion of the compartment and then upwardly away from the housing, and wherein with said housing in another operational orientation and said sweeping broom rotating within the compartment, the yard tool performs a sweeping operation by moving debris forwardly relative to the direction of forward machine motion and away from a rear portion of the compartment, and wherein said snow impeller and said sweeping broom are rotated in opposite directions relative to the direction of forward machine motion during the snow throwing operation and sweeping operation; and a handle extending from the housing. 2. The convertible yard tool of claim 1 wherein said housing includes a removable debris shield which deflects debris forwardly during the sweeping operation. 3. The convertible yard tool of claim 1 further comprising: a plurality of ground engaging elements, wherein a first element supports at least part of the yard tool on a snow surface during the snow throwing operation and a second element supports at least some of the yard tool on a ground surface during the sweeping operation. 4. The convertible yard tool of claim 3 wherein the first element is a scraper bar. 5. The convertible yard tool assembly of claim 3 wherein the second element is a skid or a wheel or both. 6. The convertible yard tool assembly of claim 1, further comprising: a control grip located at an upper portion of the handle, wherein the control grip is rotated about a longitudinal axis of the handle so that the control grip is provided in a generally similar user orientation during both the snow throwing operation and the sweeping operation. 7. The convertible yard tool assembly of claim 1 further comprising: a selectively removable dust shield which deflects debris thrown by the sweeping broom during the debris sweeping operation. 8. The convertible yard tool assembly of claim 1 further comprising a pair of support elements, wherein the yard tool is supported upon on a snow surface by one of the pair of support elements during the snow throwing operation, and the yard tool is supported on a ground surface by the other one of the pair of support elements when the housing is in a sweeping orientation. 9. The convertible yard tool assembly of claim 1 wherein the handle includes a control grip which is rotated about a longitudinal axis of the handle during a conversion between the snow throwing operation and the debris sweeping operation. 10. The convertible yard tool assembly of claim 9 wherein the control grip is provided in generally the same orientation to the user during the snow throwing operation and the debris sweeping operation. 11. A convertible yard tool comprising: a debris sweeping broom; a snow throwing impeller; a housing defining a compartment, said housing being supported upon a ground surface in at least two operational orientations, wherein with said housing in one operational orientation and said snow throwing impeller rotating within the compartment, the yard tool performs a snow throwing operation by moving snow initially rearwardly relative to a direction of forward machine motion toward a rear portion of the compartment and then upwardly away from the housing, and wherein with said housing in another operational orientation and said debris sweeping broom rotating within the compartment, the yard tool performs a sweeping operation by moving debris forwardly relative to the direction of foward machine motion and away from a rear portion of the compartment, and wherein said snow throwing impeller and said debris sweeping broom are rotated in opposite directions relative to the direction of forward machine motion during the snow throwing operation and sweeping operation; and a handle extending from the housing. 12. The convertible yard tool assembly of claim 11 further comprising a non-reversible electric motor which rotates the snow impeller or the broom. 13. The convertible yard tool of claim 11 further comprising a control grip provided at an upper portion of the handle. 14. A convertible yard tool assembly comprising a debris sweeping broom; a snow throwing impeller; a housing operated relative to a ground surface in either a snow throwing orientation or a sweeping orientation, wherein said impeller throws snow rearwardly toward a wall surface of the housing during a snow throwing operation, and wherein said broom sweeps debris forwardly relative to the housing during a sweeping operation, and when viewed from a side of the housing, said snow impeller being rotated in a counter-clockwise direction during the snow throwing operation, and said sweeping broom being rotated in a clockwise direction during the sweeping operation; a handle extending from the housing; and a control grip provided at an upper portion of the handle, wherein the control grip is rotated approximately 180 degrees about a longitudinal axis of the handle during a change from the snow throwing operation to the sweeping operation. 15. The convertible yard tool assembly of claim 11 further comprising a wheel and a scraper bar, wherein the housing is supported upon the wheel during the sweeping operation and the housing is supported upon the scraper bar during the snow throwing operation. 16. The convertible yard tool assembly of claim 11 further comprising a dust shield positioned between the broom and a user during the sweeping operation. 17. The convertible yard tool assembly of claim 16 wherein the dust shield is removed prior to the snow throwing operation. 18. A convertible yard tool comprising: a housing adapted to carry a snow impeller or a sweeping broom; an electric motor which rotates the snow impeller or the sweeping broom within the housing, said housing being supported upon a ground surface in at least two operational orientations, wherein with said housing in one operational orientation and said snow impeller rotating within the compartment, the yard tool performs a snow throwing operation by moving snow initially rearwardly relative to a direction of forward machine motion toward a rear portion of the compartment and then upwardly away from the housing, and wherein with said housing in another operational orientation and said sweeping broom rotating within the compartment, the yard tool performs a sweeping broom are rotated in opposite direction relative to the direction of forward machine motion during the snow throwing operation and sweeping operation; and a handle extending from the housing.
