Hello there, dont be hoaxed into buying a new rotor and all the hype and b.s. That machine you have will do a perfect job on edible beans just the way it comes out of the factory. We cut a bundle of edible beans every year and in the past we used the 1440 and 1460 for the edbile beans. Now i run my 2388s in beans and they still do a fine job but not the perfect job like you will get from the smaller rotor combine. If you have any questions feel free to contact me. Good luck to you on next harvest...Where ya located atIJ
