Abstract: A rotary cement or concrete finishing trowel has an operating head at one end of the apparatus that includes at least one cement finishing blade rotatably mounted for movement in a horizontal plane for smoothing a concrete floor surface. A drive motor, e.g., a 2-cycle gas engine, is provided at the other end of the apparatus. An elongated frame element is connected between the motor framework and the operating head and is preferably rigidly connected between them. A drive shaft extends diagonally between the motor and the operating head for imparting rotation to the finishing blade. The elongated frame element can be a tubular housing that surrounds the drive shaft and is connected at one end to the motor framework and at the other end is connected to the operating head so that the operator is able to use the frame element as a handle for lifting the entire apparatus over obstructions during operation as the weight of the motor at least partially counterbalances the weight of the operating head.
