What is claimed is: 1. A utility transport comprising: a self-propelled transport assembly; a receiver; attaching means to removably attach said transport to a device having wheels and an outwardly extending projection which is to be moved; whereby said attaching means which may be removably connected to said device, and may be folded out of the way when not is use; said transport assembly comprising at least two motors and drive wheel units; means to raise and lower said motor and drive wheel units; at least two castering support wheels; at least one housing; at least one handle; means for controlling said assembly; at least one releasable hitch, and an at least two-piece articulated frame. 2. A utility transport comprising motor and drive wheel units according to claim 1, wherein each comprise a variable speed reversible electric motor and a wheel. 3. A utility transport according to claim 1, wherein said handle which allows a user to move said assembly unit exclusive of its electric motors. 4. A utility transport according claim 1, wherein said two-piece articulated frame comprises a vertical frame and a lower frame. 5. A utility transport according to claim 4, wherein said vertical frame provides means for mounting all components. 6. A utility transport according claim 4, wherein said lower frame is free to move up and down on said vertical frame in order to lift said assembly. 7. A utility transport comprising: a self-propelled transport assembly; a receiver; attaching means to removably attach said transport to a device having wheels and an outwardly extending projection which is to be moved; whereby said attaching means which may be removably connected to said device, and may be folded out of the way when not in use; said transport assembly comprising at least two motor and drive wheel units; means to raise and lower said motor and drive wheel units; at least two castering support wheels; at least one housing; at least one handle; means for controlling said assembly; at least one releasable hitch, and an at least two-piece articulated frame; second mounting means for mounting said assembly to a lower sub-frame assembly which can be raised and lowered; at least one mechanical linkage and at least one pneumatic air bag controlled by a controller. 8. A utility transport according to claim 7, wherein said two castering support wheels provide support for the unit when it is not moving said device. 9. A utility transport according to claim 7, further including batteries which are rechargeable. 10. A utility transport according to claim 9, further including charging means which may be plugged into any electrical outlet and will provide means to recharge the batteries. 11. A utility transport according to claim 7, further comprising a compressor which provides pressure to inflate said air bags sufficiently to lift one end of an object weighing up to 3,000 pounds. 12. A utility transport according to claim 11, further comprising electrical wiring and pneumatic plumbing sufficient to control operation of said assembly. 13. A utility transport according to claim 7, wherein said means for controlling said assembly comprises at least two separate joystick units. 14. A utility transport according to claim 13, wherein said means for controlling said assembly comprises a first joystick having control means to control the speed, direction, and forward or reverse motion of the unit. 15. A utility transport according to claim 14, wherein said first joystick includes control means to allow very small incremental motion to properly move heavy equipment. 16. A utility transport according to claim 15, further including a second joystick unit which allows the user to move said utility transport when it is not connected to a piece of equipment. 17. A utility transport according to claim 7, further including a releasable hitch which provides means to pull or push said device by means of said receiver. 18. A utility transport according to claim 7, further including a releasble hitch which, one closed, prevents said received from coming detached.
