There are several advantages to the dual auger system over the single auger. With side-by-side dual augers rotating into each other, it eliminates the bridging effect that is seen with single auger systems. This makes the anti-bridging device (or agitator) unneeded; reducing the hassle to operator and making the unit much safer to enter if the inside needs any maintenance. Other benefits include much greater discharge capacity, allowing the unit to be emptied twice as fast for filling exceptionally large patches versus a single auger system. Because each auger has its own drive motor, the system has twice the torque and power to break up and deliver stiff loads. Each motor, drive shaft and auger experience less stress because the workload is divided between the two; the components have a much longer life span.
