6. The motor assembly of claim 1 further comprising:

a spring coupled with said upper motor mount and with said lower motor mount, said spring for maintaining pressure upon said upper motor mount when in said first position.

7. The motor assembly of claim 1 wherein said lower motor mount further comprises:

a first positive stop and a second positive stop to limit the range of movement of said upper motor mount.

8. The motor assembly of claim 1 wherein said motor mount assembly is operable for a user to move said upper motor mount between said first position and said second position using either hand.

9. The motor assembly of claim 1 further comprising:

a cover assembly coupled with upper motor mount.

10. The motor assembly of claim 1 wherein said drive motor is selected from the group consisting of a permanent magnet brush direct current (DC) motor, a brushless DC motor, a stepper motor, and an alternating current (AC) servo motor.

11. The motor assembly of claim 10 wherein said motor generates approximately nineteen ounce/inches of torque per ampere of current.

12. The motor assembly of claim 1 wherein said drive motor is communicatively coupled with a control component, said control component for conveying a steering command to said drive motor in response to receiving position data describing the geographic position of said mobile machine.

13. A motor mount comprising:

a lower motor mount which is mechanically coupled with a steering column of a mobile machine such that said lower motor mount remains fixed with respect to said steering column when coupled therewith;

an upper motor mount comprising an integral latching lever and which is coupled with said lower motor mount via a pivot bearing, said upper motor mount for maintaining pressure upon a drive wheel in contact with a steering wheel of a mobile machine when said upper motor mount is in a first position and for keeping said drive wheel away from said steering wheel when said upper motor mount is locked in a second position; and

a positive locking mechanism coupled with said lower motor mount and with said upper motor mount, said positive locking mechanism for locking said upper motor mount in a second position wherein drive wheel is disengaged from said steering wheel.

14. The motor mount of claim 13 wherein said pivot bearing defines a point of rotation for said upper motor mount.

15. The motor mount of claim 13 wherein said bearing limits out of plane movement of said upper motor mount with respect to said lower motor mount.

16. The motor mount of claim 13 wherein said positive locking mechanism comprises a spring loaded latching pin.

17. The motor mount of claim 16 wherein said integrated latching lever engages said spring loaded latching pin when said upper motor mount is in said second position.

18. The motor mount of claim 17 wherein said integrated latching lever further prevents moving said upper motor mount to said first position when engaged with said spring loaded latching pin.

19. The motor mount of claim 13 further comprising:

a first positive stop and a second positive stop to limit the range of movement of said upper motor mount.

20. The motor mount of claim 13 further comprising:

a spring coupled with said upper motor mount and with said lower motor mount, said spring for maintaining pressure upon said upper motor mount when in said first position.

21. The motor mount of claim 13 wherein said motor mount is operable for a user to move said upper motor mount between said first position and said second position using either hand.

22. A motor mount comprising:

a lower motor mount which is mechanically coupled with a steering column of a mobile machine such that said lower motor mount remains fixed with respect to said steering column when coupled therewith;

an upper motor mount comprising an integral latching lever and which is coupled with said lower motor mount via a pivot bearing and a spring, said upper motor mount for maintaining pressure upon a drive wheel in contact with a steering wheel of a mobile machine when said upper motor mount is operated in a first position and for keeping said drive wheel away from said steering wheel when said upper motor mount is operated in a second position; and

a positive locking mechanism coupled with said lower motor mount and with said upper motor mount, said positive locking mechanism for locking said upper motor mount in a second position wherein drive wheel is disengaged from said steering wheel.

23. The motor mount of claim 22 wherein said pivot bearing defines a point of rotation for said upper motor mount.

24. The motor mount of claim 22 wherein said bearing limits out of plane movement of said upper motor mount with respect to said lower motor mount.

25. The motor mount of claim 22 wherein said positive locking mechanism comprises a spring loaded latching pin.

26. The motor mount of claim 25 wherein said integrated latching lever engages said spring loaded latching pin when said upper motor mount is in said second position.

27. The motor mount of claim 26 wherein said integrated latching lever further prevents moving said upper motor mount to said first position when engaged with said spring loaded latching pin.

28. The motor mount of claim 22 further comprising:

a first positive stop and a second positive stop to limit the range of movement of said upper motor mount.

29. The motor mount of claim 22 wherein said motor mount is operable for a user to move said upper motor mount between said first position and said second position using either hand.
