Abstract
A single action agitation element for a washing machine appliance is provided. The agitation element includes a shaft, a first fin, and a second fin. The first fin and second fin each extend outwardly from the shaft and around the shaft. The first fin extends generally in a first fin plane defining an angle greater than zero with a reference plane of the shaft. By contrast, the second fin extends generally in a second fin plane defining an angle less than zero with the reference plane of the shaft. Such a configuration may more efficiently move clothes or other articles within a wash basket of the washing machine appliance downwardly along a vertical direction during certain washing machine operations.
