A screeding device for screeding a concrete surface includes a support member, a screed head assembly mounted to the support member, and a control. The screed head assembly includes a grade setting device and a vibrating member, and is selectively movable in a screeding direction over and along the concrete surface by the support member. The vibrating member is vibratable to screed the concrete surface as the screed head assembly is moved in the screeding direction over and along the concrete surface. The control is operable to automatically stop vibration of the vibrating member when the support member is not moving the screed head assembly in the screeding direction and to automatically vibrate the vibrating member when the support member moves the screed head assembly in the screeding direction.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A screeding device for screeding a concrete surface, said screeding device comprising: a support member; a screed head assembly mounted to said support member, said screed head assembly comprising a grade setting device and a vibrating member, said screed head assembly being selectively movable in a screeding direction over and along the concrete surface by said support member, said vibrating member being vibratable to screed the concrete surface as said screed head assembly is moved in said screeding direction over and along the concrete surface; and a control operable to automatically stop vibration of said vibrating member when said support member is not moving said screed head assembly in said screeding direction and to automatically vibrate said vibrating member when said support member moves said screed head assembly in said screeding direction. 2. The screeding device of claim 1, wherein said control is operable to initially vibrate said vibrating member at an initial frequency when movement in said screeding direction is detected and to ramp up the vibration frequency of said vibrating member to an operational frequency as said screed head assembly is moved in said screeding direction, said operational frequency being greater than said initial frequency. 3. The screeding device of claim 1, wherein said control is operable to adjust the level of said vibrating member relative to said grade setting device, said control being operable to automatically initially lower said vibrating member toward and into engagement with the concrete surface after said grade setting device is lowered to a desired grade level. 4. The screeding device of claim 3, wherein said control is operable to automatically lower said vibrating member into engagement with the concrete surface in response to an activating event. 5. The screeding device of claim 3, wherein said control is operable to delay lowering said vibrating member relative to said grade setting device at least until said control receives an input indicative of at least a portion of said screed head assembly being moved to a position generally over a newly placed concrete area. 6. The screeding device of claim 5, wherein said control is operable to lower said vibrating member relative to said grade setting device a period of time following the time at which said control receives said input. 7. The screeding device of claim 5 including a vibration sensing device operable to sense the vibration generally at the concrete surface, said control delaying lowering said vibrating member at least until said control determines that said vibration is indicative of newly placed concrete. 8. The screeding device of claim 7, wherein said vibration sensing device engages the concrete surface when said grade setting device is engaged with the concrete surface, said vibration sensing device being operable to sense vibration in the concrete. 9. The screeding device of claim 7, wherein said vibration sensing device is attached to said vibrating member and is operable to sense vibration reaction in said vibrating member when said vibrating member is activated and partially engaged with the concrete surface. 10. The screeding device of claim 5 including a concrete contacting switch positioned in front of said grade setting device, said control receiving an input from said switch in response to said switch contacting excess uncured concrete in front of said grade setting device, said input being indicative of said switch being at the newly placed concrete area. 11. The screeding device of claim 10, wherein said control includes a timing device and is operable to delay lowering said vibrating member toward and into engagement with the concrete surface until a period of time has elapsed following said control receiving said input from said switch. 12. The screeding device of claim 4 including a vibration sensing device operable to sense the vibration at the concrete surface, said activating event comprising an input from said vibration sensing device to said control that is indicative of said vibration sensing device being located at the newly placed concrete area. 13. The screeding device of claim 12, wherein said vibration sensing device engages the concrete surface when said grade setting device is engaged with the concrete surface, said vibration sensing device being operable to sense vibration in the concrete. 14. The screeding device of claim 12, wherein said vibration sensing device is attached to said vibrating member and is operable to sense vibration reaction in said vibrating member when said vibrating member is activated and partially engaged with the concrete surface. 15. The screeding device of claim 4 including a concrete contacting switch positioned in front of said grade setting device, said activating event comprising an input from said switch to said control that is indicative of said switch contacting excess uncured concrete in front of said grade setting device. 16. The screeding device of claim 4, wherein said activating event comprises an input from a level detection system that is indicative of said grade setting device being a predetermined distance above the desired grade. 17. The screeding device of claim 16, wherein said level detection system comprises a laser plane reference system, said input being provided from a laser receiver attached to said screed head assembly. 18. The screeding device of claim 4 including a vertically movable sensing device, wherein movement of said vertically movable sensing device is affected by the type of concrete or degree of cure of the concrete at which said sensing device is positioned, said activating event comprising an input from said sensing device to said control that is indicative of said sensing device being located at the newly placed concrete area. 19. The screeding device of claim 1, wherein grade setting device comprises an auger rotatable to cut and establish the desired grade at the concrete surface. 20. The screeding device of claim 1, wherein said screed head assembly includes a plow at a forward end of said screed head assembly and forward of said grade setting device. 21. The screeding device of claim 1, wherein said support member comprises an extendable and retractable boom mounted to a movable base unit, said support member being retracted to move said screed head assembly over and along the surface of the newly placed concrete area to screed the newly placed concrete. 22. The screeding device of claim 1, wherein said control is operable to adjust the level of said vibrating member relative to said grade setting device via pivotal movement of said screed head assembly about a pivot axis extending generally along said screed head assembly and generally parallel to the desired grade of the concrete surface. 23. The screeding device of claim 1, wherein said control is operable to adjust the level of said vibrating member relative to said grade setting device via geiferally vertical movement of said vibrating member relative to a frame of said screed head assembly.
