A B S T R A C T The present invention presents a novel concrete floor finisher comprising a body which supports rotatable trowels with trowel blades through radial support members so that the trowels can revolve around a central shaft of the body, the body being equipped further with a driving means of the rotatable trowels, a range of equipments and a traveling means of the finisher, characterized in that the driving means of each of the rotatable trowels is a hydraulic motor connected to an engine-powered unit, and each of the motor is connected in series by hydraulic piping to be driven equally, and also discloses construction of components in detail to improve its mechanical construction adaptable to various conditions of concrete to finish. The main features of the finisher according to the present appears in the driving system to convert the driving of the rotatable trowels by electric motors or by gasline engines of prior art into a driving of hydraulic motors to eliminate their drawbacks, and moreover, following to the experiences in practical works, in utilizing of the second driving hydraulic system in adjusting the contact pressure on the surface of concrete by raising and lowering the trowels, and as well as controling the revolution of the body around the central shaft positively. That all accom- plish the machine to contribute to the workability and offer a construction of the machine from various aspects of the technology. Also in the present invention, according to disclo- sures of embodiments, various applications and combinations are available within the scope of technical concept.
