A concrete finishing machine includes two finishing cylinders with two augers mounted in line with the two cylinders, forward ends of the augers being suspended by a frame which is pivotally attached to the cylinder support frame and rearward ends of the augers being connected through flexible couplings to the output ends of the cylinder shafts, allowing adjustment in the angle of inclination of the auger support frame, pivoting the two augers relative to the plane of the cylinder shafts.
