I'm no pro, and I've only cut wheat and a bit 'o mustard, but here's what I've learned: On a stock cage (P1 cylinder) in wheat, we weren't able to run with the cage sweep system disconnected. loewen Mfd (www.loewenmfd.com) makes a P3 style cage for the N series. Not sure of the price, I'm inquiring about that (tyler@loewenmfg.com is the person I've been talking to.) I only jammed the dist. augers if I ran too much material in there. If jams are happening, you may be breaking the crop up too much, and instead of going out the back of the combine, it's running back up into the accelerator rolls again. Slow the cylinder_open up the concave, and maybe close down the top sieve if your not loosing too much grain. We put stands in the grain tank that holds the auger up about 1_2" from the "full bin" switch, keeps the u-joint on that auger from wearing out as fast.
