The invention claimed is: 1. An agricultural seeding machine, comprising: a mechanical drive providing primary power; a seed meter, including a driven shaft; a planetary gear set including an input shaft connected with said drive, an output shaft connected with said driven shaft, a ring gear, and a motor coupled with said ring gear, said motor providing a secondary power resulting in regulating movements to said ring gear to thereby regulate a speed of said driven shaft. 2. The agricultural seeding machine of claim 1, wherein said planetary gear set includes a sun gear and a plurality of planetary gears interconnecting said sun gear and said ring gear, said input shaft being coupled with said sun gear. 3. The agricultural seeding machine of claim 2, wherein said output shaft is coupled with said planetary gears. 4. The agricultural seeding machine of claim 1, wherein said drive includes one of a flexible shaft and a chain connected with said input shaft. 5. The agricultural seeding machine of claim 1, wherein said drive includes a ground driven main shaft and a flexible shaft coupled with said main shaft, said flexible shaft coupled with said input shaft of said planetary gear set. 6. The agricultural seeding machine of claim 1, wherein said motor is an electric motor having a drive shaft coupled with said ring gear. 7. The agricultural seeding machine of claim 6, further including a controller coupled with said electric motor, said controller controllably operating said electric motor to speed up or slow down rotation of said ring gear. 8. The agricultural seeding machine of claim 7, further including a sensor coupled with said controller, said sensor positioned to sense a speed of said seed meter associated with said driven shaft. 9. The agricultural seeding machine of claim 6, wherein said electric motor has a worm gear attached to said drive shaft and coupled with said ring gear. 10. The agricultural seeding machine of claim 9, wherein said ring gear includes a plurality of teeth on an outer periphery thereof, said worm gear being engaged with said plurality of teeth on said outer periphery. 11. An agricultural seeding machine, comprising: a seed meter, including a driven shaft rotating at a speed being driven by a primary power source; and an electromechanical variable speed drive for said seed meter, including a planetary gear set having an output shaft connected with said driven shaft, a ring gear, and a motor coupled with said ring gear, said motor moving said ring gear to adjust said speed of said driven shaft, said motor producing secondary power. 12. The agricultural seeding machine of claim 11, wherein said planetary gear set includes a sun gear and a plurality of planetary gears interconnecting said sun gear and said ring gear. 13. The agricultural seeding machine of claim 11, wherein said motor is an electric motor having a drive shaft coupled with said ring gear. 14. The agricultural seeding machine of claim 13, further including a controller coupled with said electric motor, said controller controllably operating said electric motor to speed up or slow down rotation of said ring gear. 15. The agricultural seeding machine of claim 14, further including a sensor coupled with said controller, said sensor positioned to sense a speed of said seed meter associated with said driven shaft. 16. The agricultural seeding machine of claim 13, wherein said electric motor has a worm gear attached to said drive shaft and coupled with said ring gear. 17. The agricultural seeding machine of claim 16, wherein said ring gear includes a plurality of teeth on an outer periphery thereof, said worm gear being engaged with said plurality of teeth on said outer periphery.
