Abstract
An adjustable agitator assembly having a hexagonal shaft to which is attached a hexagonal hub. A mounting block is attached to the hub at the desired locations. The mounting block has a receptacle to receive the splined shaft of a paddle. The splines allow the orientation of the paddle to be changed to many different discrete positions while at the same time preventing the paddle shaft from slipping. Seals are used to prevent penetration of the contacts between the various parts of the assembly by the media which is stirred.
