1. A method of removing a bucket from a turbomachine rotor wheel, the method comprising: exposing a base portion of the bucket, wherein exposing the base portion of the bucket includes removing an airfoil portion from the base portion;positioning a puffing device radially outwardly of the base portion;connecting the base portion of the bucket to the pulling device through a linking rod;exerting a force on the linking rod, the force being exerted through the pulling device, the force being directed radially outwardly of the rotor wheel, the force forcing the linking rod radially outwardly from the rotor wheel into the pulling device; andremoving the base portion from the turbomachine rotor wheel. 2. The method of claim 1, wherein connecting the base portion of the bucket includes forming a bore into the base portion. 3. The method of claim 2, further comprising: forming a plurality of threads along the bore. 4. The method of claim 1, wherein positioning the pulling device includes supporting the pulling device on a rotor ring surrounding the turbomachine rotor wheel. 5. The method of claim 1, wherein positioning the pulling device includes supporting a ram radially outwardly of the base portion. 6. The method of claim 1, wherein exerting the radially outwardly directed force includes directing a hydraulic fluid into the pulling device. 7. The method of claim 1, wherein exerting the radially outwardly directed force includes operating a screw in the pulling device. 8. The method of claim 1, wherein removing the base portion further comprises: breaking the base portion into multiple pieces; andremoving each of the multiple pieces from the turbomachine rotor wheel. 9. A method of removing a bucket from a rotor wheel comprising: exposing a base portion of the bucket, the exposing including removing an airfoil portion from the base portion;positioning a ram radially outwardly of the bucket;connecting a base portion of the bucket to the ram;exerting a radially outwardly directed force on the base portion, the exerting the radially outwardly directed force on the base portion includes forcing a linking rod radially outwardly from the rotor wheel into the ram; andremoving the base portion from the rotor wheel. 10. The method of claim 9, wherein connecting the base portion of the bucket includes forming a bore into the base portion. 11. The method of claim 10, further comprising: forming a plurality of threads along the bore. 12. The method of claim 11, wherein connecting the base portion to the ram includes establishing a threaded connection between the ram and the plurality of threads. 13. The method of claim 9, wherein positioning the ram includes supporting the ram on a rotor ring surrounding the rotor wheel. 14. The method of claim 9, wherein forcing the linking rod radially outwardly includes directing pressurized fluid into the ram. 15. The method of claim 14, wherein directing a pressurized fluid into the ram include urging hydraulic fluid into the ram. 16. The method of claim 9, wherein exerting the radially outwardly directed force includes directing an electrical current to the ram. 17. The method of claim 16, wherein the electrical current powers a screw. 18. The method of claim 9, wherein removing the base portion further comprises: breaking the base portion into multiple pieces; andremoving each of the multiple pieces from the rotor wheel.
