Abstract: 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.

Abstract: A bi-directional concrete finishing machine finishes a concrete surface in both a forward and a reverse direction, and includes a leading finishing roller and a trailing finishing roller which rotate in a first direction, and two tramming rollers disposed between the leading and trailing finishing rollers, which rotate in a second direction, such that the tramming rollers can be driven in the second direction to move the concrete finishing machine forward and, with the trailing finishing roller disengaged, the leading finishing roller can rotate in the first direction and level the concrete to grade. When the machine is reversed by driving the tramming rollers in the first direction, the leading finishing roller is disengaged, and the trailing finishing roller is driven in the second direction and levels the concrete to grade. Another embodiment of the machine includes a concrete auger for roughing the concrete and spreading it out evenly, which is added as a fifth roller to the machine.
