CA 2301783

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. Still another embodiment includes a steering mechanism which is extended from under the machine and allows the machine to turn in any direction. A lifting cradle lifts the concrete finishing machine into place over the unfinished concrete.
