A self-propelled lawn mower and sulky device. The self-propelled lawn mower comprises handle bars and an operator console that are positioned between the front end and rear end of the lawn mower. A securing bar and a placement bar are designed and situated an a angle to one another to appropriately position the handle bars and operator console. The sulky device comprises an operator platform, a pair of sulky arms, a pair of caster wheels, and a hitch bar. When the sulky device is mounted to the self-propelled lawn mower, a first hinge means is used for attaching the operator platform to the hitch bar, a second hinge means is used for attaching the hitch bar to the lawn mower, and a third hinge means is used for attaching the caster wheels to the sulky arms.

1. A sulky for attachment to a self-propelled lawn mower having a front end, a rear end, a left side, a right side, a pair of front wheels situated at the front end and a pair of rear wheels situated at the rear end, comprising: an operator platform having a proximal end and a distal end;a pair of s
1. A sulky for attachment to a self-propelled lawn mower having a front end, a rear end, a left side, a right side, a pair of front wheels situated at the front end and a pair of rear wheels situated at the rear end, comprising: an operator platform having a proximal end and a distal end;a pair of sulky arms fixedly secured to the operator platform;a pair of caster wheels, the pair of caster wheels each having a front, a middle, and a rear, the middle equally positioned between the front and the rear;a hitch bar having a proximal end and a distal end and a pair of opposed hinge arms;a first hinge means for releaseably attaching the proximal end of the operator platform to the distal end of the hitch bar and permitting the operator platform to pivot about a first axis of rotation in relation to the hitch bar;a second hinge means for releaseably attaching one of the opposed hinge arms at the proximal end of the hitch bar to the left side of the self-propelled lawn mower and the other of the opposed hinge arms at the proximal end of the hitch bar to the right side of the self-propelled lawn mower, the second hinge means positioned adjacent to each of the rear wheels, the second hinge means permitting the hitch bar to pivot about a second axis of rotation in relation to both the left and right side of the self-propelled lawn mower and adjacent to the pair of rear wheels;a third hinge means for attaching the caster wheels to the sulky arms, the middle of the caster wheels situated in substantial alignment with the distal end of the operator platform, the third hinge means permitting the caster wheels to pivot about a third axis of rotation in relation to the sulky arms; andwherein the first axis of rotation, the second axis of rotation, and the third axis of rotation are each different than one another. 2. The device of claim 1 wherein the first axis of rotation is about a first horizontal axis. 3. The device of claim 2 wherein the second axis of rotation is about a second horizontal axis, the second horizontal axis substantially perpendicular to the first horizontal axis. 4. The device of claim 1 wherein the third axis of rotation is about a vertical axis. 5. The device of claim 1 wherein the first hinge means comprises a shaft having a shaft hole, a tube, a means for securing the tube to the operator platform, and a first pin securing means for releaseably securing the shaft to the tube. 6. The device of claim 5 wherein the first pin securing means comprises a pin, a wheel, and a fastening member. 7. The device of claim 1 wherein the second hinge means comprises the hinge bar having the pair of opposed hinge arms, each hinge arm providing a hinge hole, a mounting bracket, an interconnecting bracket, and a second pin securing means. 8. The device of claim 1 wherein the third hinge means permits the caster wheels to pivot substantially three hundred and sixty degrees about the third axis of rotation in relation to the sulky arms. 9. The device of claim 1 wherein the third hinge means comprises a tube and a yoke having a yoke shaft. 10. The device of claim 1 wherein the rear end of the self-propelled lawn mower further defines a vertical plane. 11. The device of claim 10 wherein the self-propelled lawn mower comprises at least one handle bar, the at least one handle bar positioned between the front end and rear end of the self-propelled lawn mower and forward of the vertical plane. 12. The device of claim 10 wherein the at least one handle bar comprises a securing bar and a placement bar, each formed at an angle to one another. 13. A sulky for attachment to a self-propelled lawn mower having a front end and a rear end, a left side and a right side, a pair of rear wheels situated at the rear end, and the rear end further defining a vertical plane, comprising: an operator platform having a proximal end and a distal end;a hitch bar having a proximal end and a distal end and a pair of opposed hinge arms;means for attaching the proximal end of the operator platform to the distal end of the hitch bar;one of the opposed hinge arms at the proximal end of the hitch bar affixed to the left side of the self-propelled lawn mower and the other of the opposed hinge arms at the proximal end of the hitch bar affixed to the right side of the self-propelled lawn mower;a pair of caster wheels, the pair of caster wheels each having a front, a middle, and a rear, the middle equally positioned between the front and the rear;means for attaching the pair of caster wheels to the operator platform;the middle of the caster wheels situated in substantial alignment with the distal end of the operator platform;at least one handle bar having a proximal end and a distal end and comprising a securing bar and a placement bar, the securing bar originating at the proximal end of the at least one handle bar and affixed to the self-propelled lawn mower, the securing bar extending upwardly and away from the rear end toward the front end of the self-propelled lawn mower, the other end of the securing bar affixed to the placement bar, the placement bar extending upwardly and toward the rear end of the self-propelled lawn mower, the placement bar terminating in a gear handle at the distal end of the at least one handle bar;the gear handle positioned in a substantially vertical alignment with the proximal end of the at least one handle bar and situated forward of the vertical plane between the front end and rear end of the self-propelled lawn mower;means for permitting the operator platform to rotate about a first axis of rotation in relation to the self-propelled lawn mower;means for permitting the operator platform to rotate about a second axis of rotation in relation to the self-propelled lawn mower; andmeans for permitting the operator platform to rotate about a third axis of rotation. 14. The device of claim 13 wherein the first axis of rotation is about a first horizontal axis. 15. The device of claim 14 wherein the second axis of rotation is about a second horizontal axis, the second horizontal axis substantially perpendicular to the first horizontal axis. 16. The device of claim 13 wherein the third axis of rotation is about a vertical axis.
