Abstract
A wheeled strike-off apparatus is movable over a surface of uncured concrete or subgrade materials and is operable to establish a desired grade of the uncured concrete surface or subgrade surface. The apparatus includes a wheeled support and a plow assembly. The plow assembly may be adjustably mounted to a front frame portion and may be vertically adjustable relative to the frame portion. The plow assembly may include a plow member for engaging and establishing the desired grade and/or may include a vibrating member for vibrating and smoothing the concrete after the plow member establishes the desired grade. The apparatus may include a user input that is adjustable by an operator to adjust a down pressure of the plow assembly at the concrete when the wheeled support is moved in a rearward direction.
