I have that option on my 2366. I never thought it was a big deal, but after having it I did adjust spacing for soybeans more as the day dried out. It's one of those things you don't know whether it's worth it until you do have it, I guess. I do have trouble binding up with dust and_or chaff though. Just blow out the adjuster with compress air once in a while. I don't remember if it was standard equipment or an option.
