I was told at a GlEANER Performance meeting to run the Rear Feed Conveyor Chain in the Corn Setting on soybeans. This will allow more room for the beans to come in at the transition point, while at the same time allowing the chain to grasp enough of material to continue up to the rotor. Front feeder house chain is run in grain position. (Besides, those rear blocks are a pain in the tail to change anyway from Grain to Corn)I don't know if that will fix your problem. Header feeding is critical. I hear from people that an air reel helps feeding dramatically, especially in short beans. A tip for unplugging the slug between the two chains: Have your separator running, then hit the reverser while still at full throttle. At the same time, try then raising and lowering your header at different positions to see if the correct angle at the transition point can be achieved to back it out.
