Hi everyone! Not sure if this is the forum I should be posting this in but here it goes. We have always run the slow down kits in our John Deere combines for harvesting edible beans. Last year was the first year we really got into yeild mapping and we saw that there were no maps for our edibles. We thought it was maybe something else but there was one field that we combined with the normal drive pulley and they registered fine. My question has anyone else had this problem and what have you done to rectify this. White beans are a few weeks away here so have some time to try to figure it out. BTW this is on S680 combines. Thanks
