ABSTRACT:
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.
