Claim 15:
16. A floor treating machine comprising:
a. a chassis adapted to be moved along the floor;
b. a variable speed motor affixed to the chassis;
c. a controller coupled to the motor and adapted to control the speed of the motor;
d. a drive driven by the variable speed motor, said drive comprising a motor shaft, a first drive shaft, a first plate adapted to be coupled to the first drive shaft so that the first plate extends perpendicular to the first drive shaft, a second drive shaft, and a second plate adapted to be coupled to the second drive shaft so that the second plate extends perpendicular to the second drive shaft, wherein the first drive shaft, first plate, second drive shaft and second plate are all adapted to spin together at revolutions per minute corresponding to the speed of the variable speed motor;
e. a first pad of a preselected type attached to a floor facing surface of the first plate and adapted to spin together with the first plate, and a second pad of a preselected type attached to a floor facing surface of the second plate and adapted to spin together with the second plate;
f. an indicator member identifying the type of pad attached to the first plate; and
g. a sensor adapted to interact with the indicator member to send a signal to the controller indicative of the type of pad attached to the first plate, wherein the controller adjusts the maximum speed at which the variable speed motor operates based on signals received from the sensor.
