A screeding machine for screeding an uncured concrete surface includes a wheeled unit having a plurality of wheels for moving the wheeled unit over a support surface. A screed head assembly includes a grade setting device and a vibrating member and is movable over the concrete area via the wheeled unit. The grade setting device includes an at least partially cylindrical concrete engaging surface, such as a roller that is rotatably mounted at the screed head assembly and rotatably driven about its longitudinal axis. The screed head assembly may include a wiper element disposed along the roller and configured to wipe or remove excess concrete from the roller during rotation of the roller about its longitudinal axis. The grade setting device or roller plow assembly may be provided as an aftermarket kit for attachment at a screed head assembly of a screeding machine.

1. A roller plow kit for attachment at a screed head of a screeding machine to provide a roller plow at said screed head to establish a grade of uncured concrete in front of at least a vibrating member of said screed head, said roller plow kit comprising: a roller plow assembly comprising a motor, a roller plow frame, end brackets and a roller configured to be rotatably disposed between said end brackets;wherein said end brackets are configured for attachment at said screed head;wherein said roller is attached at said end brackets via respective axle ends of said roller and respective support bearings and is rotatable about a longitudinal axis;wherein said motor is disposed at one of said end brackets and is operable to rotatably drive said roller relative to said end brackets;wherein, with said end brackets attached at said screed head, said motor is connectable to a control system of said screeding machine so that an operator of said screeding machine can control said motor to rotate said roller plow while screeding uncured concrete with said screeding machine, and wherein said motor of said roller plow assembly is operable independent of said vibrating member of said screeding machine. 2. The roller plow kit of claim 1, wherein said roller comprises two longitudinally aligned rollers, each having an outboard end supported at respective support bearings of respective end brackets and an inboard end supported at a central bearing of said roller plow kit, wherein said central bearing is configured for attachment at said frame of said roller plow assembly. 3. The roller plow kit of claim 1, wherein said end brackets are configured to pivotally attach at said screed head and wherein, with said end brackets pivotally attached at said screed head, said end brackets are pivotable to movably position said roller at one of a use position, where said roller is positioned generally in front of said vibrating member of said screed head, and a non-use position, where said roller is positioned away from and generally above and forward of said vibrating member of said screed head. 4. The roller plow kit of claim 1, comprising a wiping element disposed along said roller and configured to wipe concrete from the outer surface of said roller during operation of said roller plow assembly when said end brackets are attached at said screed head. 5. The roller plow kit of claim 4, wherein said wiping element is adjustably disposed at said frame of said roller plow assembly to adjust a clearance between said wiping element and the outer surface of said roller. 6. The roller plow kit of claim 5, wherein said wiping element is pivotally mounted at said frame and is pivotable between a use position, where said wiping element is positioned at or near said roller for wiping concrete from the outer surface of said roller, and a non-use position, where said wiping element is positioned away from said roller for access to said wiping element and said roller. 7. The roller plow kit of claim 1, wherein said end brackets are adjustable to allow for vertical adjustment of said plow relative to said vibrating member when said end brackets are attached at said screed head. 8. The roller plow kit of claim 7, comprising shim plates at at least one end of said roller to adjust a height of said support bearing at said at least one end of said roller. 9. The roller plow kit of claim 7, wherein said motor is at least one of (i) electrically connectable to an electronic control system of said screeding machine and (ii) hydraulically connectable to a hydraulic control system of said screeding machine. 10. A method of providing a roller plow kit at a screed head of a screeding machine, said method comprising: providing a screed head comprising a vibratable member and an auger device disposed in front of said vibratable member in a screed pass direction;providing a roller plow kit comprising a roller plow assembly having a motor, a frame, end brackets and a pair of rollers configured to be longitudinally aligned and rotatably disposed between said end brackets, wherein said rollers are rotatable about a longitudinal axis, and wherein outboard ends of said rollers are attached at respective support bearings at said end brackets and inboard ends of said rollers are attached at a central support bearing of said roller plow assembly;attaching said end brackets and said central support bearing at a frame of said screed head, wherein, with said end brackets attached to said frame of said screed head, said rollers are disposed in front of said auger device in the screed pass direction; andconnecting a motor of said roller plow assembly to a control system of at least one of said screed head and said screeding machine, wherein said motor, when connected to said control system, is operable to rotatably drive said rollers relative to said support bearings and said end brackets, and wherein said motor of said roller plow assembly is operable independent of said vibratable member of said screeding machine. 11. The method of claim 10, wherein attaching said end brackets comprises pivotally attaching said end brackets to said frame of said screed head, wherein, with said end brackets pivotally attached to said frame of said screed head, said end brackets are pivotable to movably position said rollers at one of a use position, where said rollers are positioned generally in front of said auger device, and a non-use position, where said rollers are positioned away from and generally above and forward of said auger device. 12. The method of claim 10, wherein said roller plow assembly comprises at least one wiping element disposed along said rollers and configured to wipe concrete from the outer surface of said rollers during operation of said roller plow assembly. 13. The method of claim 12, wherein said wiping element is adjustably disposed at said frame of said roller plow assembly to adjust a clearance between said wiping element and the outer surface of said rollers. 14. The method of claim 12, wherein said wiping element is pivotally mounted at said frame of said roller plow assembly and is pivotable between a use position, where said wiping element is positioned at or near said roller for wiping concrete from the outer surface of said rollers, and a non-use position, where said wiping element is positioned away from said rollers for access to said wiping element and said rollers. 15. The method of claim 9, comprising vertically adjusting said rollers relative to said end brackets when said end brackets are attached to said frame of said screed head. 16. The method of claim 9, wherein connecting said motor of said roller plow assembly to said control system comprises at least one of (i) electrically connecting said motor to an electronic control system and (ii) hydraulically connecting said motor to a hydraulic control system.
