Claim 4:
5. A toy lawnmower assembly for facilitating a child to safely trim a lawn, said assembly comprising:
a housing having structural features being molded into said housing to define a motor portion of said housing extending upwardly from a deck portion of said housing wherein said housing is configured to have the ornamental appearance of a push type lawn mower, said motor portion having a top wall, said housing having a shaft receiver extending downwardly from said top wall of said motor portion, said shaft receiver having a distal end with respect to said top wall, said distal end having a shaft well extending toward said top wall, said deck portion having an upper wall and a perimeter wall;
a plurality of wheels, each of said wheels being rotatably coupled to said housing thereby facilitating said housing to be rolled along a support surface, each of said wheels being positioned on said perimeter wall of said deck portion of said housing, each of said wheels being aligned with a respective one of four corners of said perimeter wall;
a handle being coupled to and angling upwardly from said housing wherein said handle is configured to be gripped by a child such that the child can push said housing in the convention of a lawn mower, said handle having a central portion being perpendicularly oriented between a pair of outward portions, each of said outward portions having a distal end with respect to said central portion, each of said outward portions being engaged to a respective engagement point on said upper wall of said deck portion of said housing at a point located adjacent to said distal end of said outward portions;
a drive unit being movably integrated into said housing, said drive unit being in mechanical communication with at least one of said wheels, said drive unit being rotated when said at least one wheel is rotated, said drive unit comprising:
a primary gear being positioned around an axle extending between a rear pair of said wheels such that said primary gear rotates about a rotational axis of said axle when said rear pair of wheels rotates, said primary gear having a front face, said front face having a plurality of teeth extending away from said front face, said teeth being spaced apart from each other and being distributed around a perimeter of said front face such that said teeth encircle said rotational axis of said axle;
a first pulley being rotatably disposed on a bottom side of said upper wall of said deck portion of said housing;
a shaft having an upper end and a lower end, said shaft being rotatably disposed in said shaft well in said distal end of said shaft receiver, said upper end being positioned within said shaft well, said lower end being spaced downwardly from said distal end of said shaft receiver;
a second pulley being positioned directly around said shaft such that said second pulley rotates said shaft about an axis extending through said upper end and said lower end;
a belt extending around said first pulley and said second pulley such that said second pulley is rotated when said first pulley rotates; and
a secondary gear having an upper surface and an outer surface, said upper surface being coupled to said first pulley, said outer surface tapering inwardly from said upper surface, said outer surface having a plurality of teeth being integrated into said outer surface and being distributed around said outer surface, said plurality of teeth on said outer surface engaging said plurality of teeth on said front face of said primary gear such that said secondary gear rotates said first pulley when said primary gear rotates; and

a trimming unit being coupled to said drive unit, said trimming unit being rotated when said drive unit is rotated, said trimming unit being directed downwardly on said housing wherein said trimming unit is configured to trim the lawn when said housing is pushed along the lawn, said trimmer unit comprising:
a trimming head having a top surface and a perimeter surface, said top surface being coupled directly to said lower end of said shaft such that said trimming head is rotated when said shaft rotates, said shaft being centrally positioned on said top surface; and
a plurality of filaments, each of said filaments being coupled to and extending away from said perimeter surface of said trimming head wherein each of said filaments is configured to strike grass growing in the lawn when said trimming head is rotated thereby trimming the grass.
