I just purchased my first Gleaner with a turret and would not buy another with a swivel auger. The turret clears my trucks and carts and don't have to worry about the swivel auger hitting the side. True, the turret is very noisy, however, I rented a 9650STS when my machine was broke down last fall and the auger was as noisy or noisier than the turret on this Gleaner. I guess that's why they make both the turret and swivel, you can have whichever one you want.
