No matter, either model will out perform anything but a larger lexion. Three grates through the rock trap is it for the most part. And they weigh only about 15lbs a piece, unlike other grates. You leave the main threshing concave alone and only change out the pre-concave segments. Raise the feeder house and open the rock trap and concave all the away and they are right in front of you. It might take you 15 mins. the first time, after that, 5 mins., 10 tops. Lexion has a couple more add-ons to the concave if in really tough conditions but, between the wheat pre-concaves and the lever operated concave filler plates, you should do fine.
