Our 16" by 70' Bergen used a hydraulic drive swing away. Worked good and didn't have a problem matching the speeds of both augers. There was a decal on the side that said "Run 300 rpms." A tractor that was needed to run an auger that size most of the time would have adequate hydraulics and so our JD 7410 was a good fit for it. But I'm guessing most farmers wanted a gear box drive to lessen the tractor requirements.

why use right angle gearboxes for swing auger?
