1. 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 first drive shaft and a plate adapted to be coupled to the first drive shaft and extending perpendicular to the first drive shaft, the first drive shaft and plate adapted to spin together at revolutions per minute corresponding to the speed of the variable speed motor;
e. a pad of a preselected type attached to a floor facing surface of the plate and adapted to spin together with the plate;
f. an indicator member identifying the type of pad attached to the 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 plate, wherein the controller adjusts the maximum speed at which the variable speed motor operates based on signals received from the sensor.
