ABSTRACT A power transmission system for small vehicles or machinery having a principal forward speed and variable forward and reverse speeds capable of providing lower variable speeds is disclosed. The transmission system includes a primary transmission and a secondary transmission connected in series. In one of three positions, the two transmission housings and primary output shaft are keyed together. This results in a non-variable output, principal forward speed with a 1 to 1 ratio between the speed at which the engine rotates the primary transmission housing and the speed of the output shaft. In a second setting, the secondary transmission hous- ing is keyed only to the output shaft from the primary trans- mission. This results in a forward speed having a variable output depending upon the load placed on the input shaft to the primary transmission. In a third position, the housings for the primary and secondary transmissions and the output shaft from the primary transmission are each disengaged from each other. In this setting, the secondary transmission functions to reverse the direction of the output shaft while the primary transmission functions to provide a variable gear ratio depending upon the load placed upon the input shaft to the primary transmission.
