Abstract
A method of establishing a desired grade of an uncured concrete surface or subgrade surface includes providing a wheeled apparatus having a wheeled support and a plow assembly, which may include a plow member for establishing the desired grade and/or a vibrating member for vibrating and smoothing the concrete. The down pressure of the plow assembly may be adjusted when the wheeled support is moved in a rearward direction. The elevation of the plow member may be controlled when a direction signal is indicative of the wheeled support stopping and/or moving in the forward direction. The rearward speed of the wheeled support may be reduced in response to a detection of a surface irregularity of the subgrade, and the frame portion and/or the plow assembly may be controlled to substantially maintain the plow assembly at a desired orientation when the wheel engages the detected surface irregularity.
