If the paddles were timed right it wasn't a problem they fed and worked like a charm and lasted for thousands of hours. In severe wrapping conditions you would add 2 paddles per paddle and that would eliminate the wrapping. It was the best feeding system out there simple and maintenance free. We still have an old 860 as a second combine and with over 3000 hrs those paddles have NEVER been replaced.
Curiosity has me, how was the drive chain life? If memory serves me right it was double 50 on a 850 massey.
Thanks! Things like that drive my interest
