The foundation of the circular beater is a cold-rolled, steel shaft securely fastened at each end of the rear of the spreader box. This shaft does not revolve, but forms a sort of a curved axle on which the beater revolves. The great advantage of the circular beater is that it spreads more than twice its own width — away beyond the wheels on each side. The circular beater is imitated as closely as the patents allow but none of the imitations will give you the positive, uniform, wide, even spread of the Fearless.
