Conventional vertical axis clothes washers use a mechanical transmission to oscillate the agitator when the motor rotates in one direction, and to spin the basket and agitator together when the motor rotates in the other direction. A mechanically simpler drive system uses a motor which can reverse direction rapidly for agitation and rotate in one direction for spin, but a mode shifting device is still required to decouple the basket from the agitator during agitation and to couple them during spin. This is a simple mode shifter that uses only 2 or 3 more parts than are required to attach the pulley to the agitator shaft. It can be used either with a belt drive system or a direct drive system.
