A single roller concrete finishing machine for finishing a concrete surface includes a primary motorized unit and a secondary unmotorized unit disposed on each side of a surface to be paved, with a single roller disposed on the unfinished surface which connects the primary unit and the secondary unit. The primary unit includes a first base having an elongated first handle having two ends, one end of the first handle being connected to the first base, and the other end of the first handle being connected to handlebars, below which an engaging lever is disposed. The secondary unit includes a second base with an elongated second handle similar to the first handle, but without the engaging lever. The handles of each of the primary unit and the secondary unit are swingably adjustable in a horizontal plane to aid in the leveling of the concrete surface to be finished. The primary unit has an engine mounted on the first base, and a mechanism to rotate the roller. When the engine is turned on, the roller does not rotate. Only when the engaging lever is pressed, does the roller tube rotate, in order to drive the primary unit forward, bringing the secondary unit with it, so that the forward motion of the concrete finishing machine, coupled with the pulling backward motion of the operator and helper, can level the concrete.
