Abstract
The invention is directed to an improved mixing arrangement for securing the blade to the shank of a mixing apparatus. The blade includes a borehole which overlies and surrounds a substantial portion of the shank so as to substantially reduce direct abrasive contact of the shank. Accordingly, the shank has longer life. Further the blade is mounted and secured by a single bolt which when unsecured allows the blade to be axially moved off the shank from an upright position which is most easily accessible by a person performing maintenance on the mixing apparatus.
