My experience with 8460's and the Claas 108Sl Maxi is that they will easily outperform the Deere 9600 in small grains due to larger cleaning and separation area. In corn they were particular for quality due to the smaller diameter cylinder but if set-up right would then also outperform the Deere. Grain tank size was always a challenge in high yielding crops. Fuel economy always goes to the Claas designed product by a wide margin.
