Does anyone have experience with Gorden rotor bars on a 2388? We harvest wheat with interrupter bars in the first concave and where the returns come in on the third concave but have to have the concave and shoe settings reasonably close to get an acceptable sample. Also with asian raddish we put whole pods out the back even though we have the concaves blanked off and zeroed to the rotor and the vanes on fine. We are now thinking off putting either a standard rotor in or these gorden bars to improve effeciency of the combine. Any comments would be well received.thankyou
