I can't imagine it being worse than having a clogged round baler; especially baling Maze stalks.
My 1209's (had 2 over the years) never were a problem in that regard. Would pick up a little on the far side between the frame and the wheel, but no problem to dislodge. But:
My peeve was sickle bar related: loosing sections, crawdad mounds, stem juices making a wad of cut material right at the base of the cutter which had to be cleaned out rather frequently so that the cutter could cut, and last but not least by any means, removing and reinstalling the sickle bar.
Thanks for your reply,
