I can't agree with that. From what I've seen, the feed accelerator works very well and doesn't crack grain. In Canada we also harvest dry peas and chickpeas, and I haven't heard an STS owner complain about splits or seed coat damage. If a guy is worried about it, it does have a two speed, and I think you can get smooth wear strips. When the goin' is tough, it still manages to feed the cylinder evenly. I've never talked to a Massey XP rotor owner, so I'll be quiet about it, but I know the Case screw_auger impellers throw everything off to one side and it forms a big rope before going in. That is why you hear that "thump,thump,thump" underneath your feet when in tough conditions operating axial-flows. That is the big elephant ear grabbing and pushing it into a wad in the transition cone. That is also why the transition cones wear out three times as fast on the left side than the right. Slug feeding never did much for seed quality. I also don't get the "the distance between the top opening of the feederhouse and the fast system" causing damage comment. The fast system is undershot. Crop comes in along the bottom of the feederhouse, goes under the accelerator beater, then onto the ramps into the cylinder. There really isn't any opening at the top, and grain can't get up there anyway.
