7720 that is a grain only machine,the main cylinder dose not have triple option speed sheeve, IE corn,bean machine, wanting to harvest blackeyes,even with a slow down kit JD dealer says that with this slowdown kit it can only get it down to about 300 rpm, need to get it down to about 175-250 rpm, can buy a triple option cylinder drive but dealer says would cost $2-$3000 any other options, a freind has a 6620 it has the triple option drive on it and he is running it in the high speed slot and can get down to 170 rpm? any help would be app, thanks.
