Which deflectors are you talking about? The ones on the side that are adjustable? I too was disappointed last year in soybeans with the spread pattern. We've got the tailboard adjusted all the way up & the rotor discharge panel updated. They also installed the rubber deflector/flap from the shoe to the top of the chaff spreader. Keep us informed with all your updates as our combine is a 2012 & feel that we are the ongoing prototype test machine.Take the deflectors out at the rotor discharge, it will spread like a banshee!!!
