I was just curious if anyone has done a side by side between these 2 class size combines in soybeans. I think in corn (below 20%) the clean grain elevator is the limiting factor so I don't see the advantage of the extra power. If you were cutting 50 to 60 bushel soybeans with a 30 foot draper, could the 2588 (6088) pick you up an extra mile per hour? We bought a performance chip, but I think that these chips are very overated. I am assuming that the 30% is actually only giving us an extra 20 horsepower. We can pick up almost .5 mph with the chip in the 30% position. Maybe I was expecting too much and the extra horsepower just doesn't go that far.
