ABSTRACT:
A riding-type surface working machine includes a pair of rotors each of which carries a plurality of trowels or surface working members. Each rotor includes a transmission unit and power from the engine is transmitted through each transmission unit to rotate the individual rotors. To provide directional movement for the machine, the upper end of each rotor includes a shaft that is connected to the respective transmission unit. The shaft is mounted for universal tilting movement with respect to the frame of the machine. An eccentric is mounted on each rotor shaft and is rotatable in a fixed sleeve. Each eccentric is connected through a chain drive to a vertical control stick and the control sticks for the respective rotors are mounted concentrically on the machine. Through manual operation of the control sticks the eccentrics can be individually rotated to thereby tilt the rotors to cause directional movement of the machine. To enable the machine to be transported, a group of wheels are connected to the protective guard that surrounds the rotors and can be pivoted between an upper storage position and a lower transporting position.
