with the kuchar plates you don't have to take them out for beans, however I have got in the habit of taking them out after corn (time permitting) due solely to the fact of not having to worry about dust build up - I usually have some milo to cut and if the fillerplates have any dust trapped that's when vibration becomes a problem when I speed the cyl. back up for milo - if you have beans only after corn you will see very little difference in performance with them in or out. Cylinder vibration in beans with the kuchar plates is way less than with deere fillers, but you will still have some.
If you have a cordless elcetric impact, it takes about an hour and a half to pul the plates out. I prefer to pull the feed plate and hinge for easier access.
I'm near Liberal, MO - most corn is 3/4 stand at best but looks ok for what it is - beans are looking good and the milo I have to cut looks good.
