In an exemplary embodiment, a compact lawn mower that includes at least a shroud positioned a fixed distance from a lawn, by a common rear axle extended between and supported by a pair of rear wheels, is provided. The exemplary embodiment further includes a motor adjustment member confined within and supported by the shroud. The motor adjustment member interacts with a motor, which includes a cutting member attached to a motor shaft of the motor. In the exemplary embodiment, by manipulating the motor adjustment member, the height of the cutting member relative to the surface is set. That is, the motor adjustment member is rotated in a first direction to move the motor closer to the lawn, and in the opposite direction to move the motor further from the lawn, allowing the grass to be cut to a desired length, while the shroud remains a fixed distance from the lawn.

What is claimed is: 1. A lawn mower comprising: a shroud positioned a fixed distance from a surface by a rear axle supported by a pair of rear wheels; a motor adjustment member confined by the shroud; a motor in sliding communication with the shroud and communicating with the motor adjustment member; a cutting member coupled to the motor, wherein a cutting height of the cutting member relative to the surface is set by manipulation of the motor adjustment member to fix a vertical position of the motor relative to the shroud; a pair of front wheels mounted on opposing ends of a common front axle; a steering tongue enclosing the common axle and disposed between and adjacent to the pair of front wheels; a pivot mechanism pivotally securing an attachment member of the steering tongue to the shroud; and a push handle comprising a pair of rotatable connecting members, in which each connecting member is attached to the common front axle and positioned adjacent opposing ends of the steering tongue, while being disposed between a corresponding wheel of the pair of front wheels and a corresponding end of the opposing ends of the steering tongue, and wherein the front wheels pivot into misalignment relative to the rear wheels to turn the lawn mower in response to an applied steering force. 2. The lawn mower of claim 1, further comprising an energy source communicating with the motor and providing energy for operation of the motor. 3. The lawn mower of claim 2, further comprising a cutter hub attached to a distal end of a power shaft of the motor and offset from a bottom side of the shroud, and in which the power shaft includes an axis of rotation and wherein the cutter hub with the cutting member attached thereon rotates about the axis of rotation of the power shaft in response to the rotation of the power shaft. 4. The lawn mower of claim 3, in which the power shaft and cutter hub with attached cutting member rotate at substantially the same speed in response to the activation of the motor. 5. The lawn mower of claim 4, in which the cutting member is selected from a group consisting of a cable, a filament, a polymer blade, and a rigid blade. 6. The lawn mower of claim 5, in which the selected cutting member is a rigid polymer blade. 7. The lawn mower of claim 6, in which the motor is selected from a group consisting of an AC motor, a DC motor, a stepper motor, and an internal combustion engine. 8. The lawn mower of claim 7, in which the energy source is selected from a group consisting of AC power, DC power, fossil fuel, natural gas, and ethanol. 9. The lawn mower of claim 5, in which the selected cutting member is a filament comprising material selected from a group consisting of a polymer and a metallic. 10. The lawn mower of claim 5, in which the selected cutting member is a rigid blade comprising a material selected from a group consisting of a metal, a ceramic, and a composite. 11. The lawn mower of claim 1, in which the shroud is formed from a material selected from a group consisting of an impact resistant polymer, a non-metallic composite material, and a metallic material. 12. The lawn mower of claim 11, in which the push handle further comprises: a bridge portion disposed between and supporting the pair of rotatable connecting members; an extension handle with a pair of connecting legs, wherein each of the connecting legs is pivotally secured to a corresponding rotatable connecting member of the pair of connecting members; and a locking member disposed between and rotatably attached to the pair of connecting legs, wherein upon rotation of the locking member in a first direction the locking member lockingly attaches to the bridge portion to maintain each of the pair of connecting legs in a position which extends a push bar of the extension handle in a direction which maximizes the distance between the push bar and the common front axle. 13. The lawn mower of claim 12, further comprising a cutter hub with attached cutting member, the cutter hub attached to a distal end of a power shaft of the motor, offset from a bottom side of the shroud, and rotates in union with the power shaft in response to an activation of the motor. 14. The lawn mower of claim 13, further comprising an energy source communicating with the motor and providing energy for operation of the motor, and in which the power shaft and cutter hub with attached cutting member rotate at substantially the same speed in response to the activation of the motor. 15. The lawn mower of claim 14, in which said energy source is selected from a group consisting of AC power, DC power, fossil fuel, natural gas, and ethanol. 16. The lawn mower of claim 15, in which the cutting member is a mower blade comprising a material selected from a group consisting of a metal, a ceramic, a composite, and a polymer.
