Sorry it took soo long to reply, (sugar beet harvest). We raise pinto and Great Northern beans. We windrow 12r30" together and use a Sund pickup to harvest with, going from 2 (really tough heavy beans) to 5.5 in moderate windrows. We don't raise any soybeans in our area which is in Western Nebraska. As far as attachments, this rotor had "shark fins" inbetween the cylinder bars in certain places, which where movable to many postions. Very impressed with it in the tough conditions, no rotor rumble at all. Corn is a week or so away, will keep you posted on its' performance.
