Well since you guys started coler bashing I will add my input to (ihc-afc"s) comment. In 10 years I have owned axial flows from a 1660 to a 2388. I now own a Deere STS. The feed accellerator does no more damage to the grain than a Case IH rock trap beater with serrated bars which is what is required to make an axial flow feed in tough conditions. Atleast the feed accellerator is easy to change from low speed to high (a belt vs.a chain and reverse of sprokets, of which the chain might last 1 year. As for the 3 stage rocket threshing system it is a rocket compared to an axial (chokeandpuke) flow. The STS has far better grain quality and more capasity, (every axial flow I owned had rotor rumble in tough conditions) standerd or specilty rotor, have never had rotor rumbel with an STS. I can think of several advantages with an STS over axil flows. A wider feeder house, concaves that are not constantly plugged with silks and leaves in corn, a larger fuel tank, larger grain bin, longer unload auger, a feeder reverser that actually WORKS when engauged, a much easyer to change roto belt(which was quite often on a 2388),more smoother responsive hydro control lever, in cab dispay of corn head deck plate spacing, A rotor speed control that will speed the rotor up in seconds under load, (compared to not at all under load),an engine air cleaner that does not require a religiuos cleaning every day, grain loss sensor pads that stay clean, (not totaly covered with trash when harvesting beans and wheat),easier to change chopper belt speed, a taller grain bin loading auger(which is easier on the grain when a bin extension is added,. To many more for me to mention. If the afx is the answer why did case ih pull it out of farm show machines befor sold last yearIJ Case ih spent to many years not improving enough on the same old design. Now that I have owened a STS Case IH will have to make alot of improvements for me to consider one.
