ABSTRACT:
A soft landing control system for a screeding device is operable to automatically lower a vibrating member relative to a grade setting device after the grade setting device is lowered to the desired grade. The control may be operable to delay lowering the vibrating member relative to the grade setting device at least until the control receives an input indicative of at least a portion of the screed head assembly being moved to a position generally over a newly placed concrete area.
