I will say I'd look at something that gives you the ability to have at minimum in cab row cleaner adjustment. I know about every one of the unit's I've ran I've been able to convert to air adjust with a little farmer thinking. Makes it so much nicer running in the fall in different conditions and then again in the spring time. Maybe I'm lazy but I hate getting out in the fall when the wind is whipping and its cold to go through 12 or 16 rows worth of pins or cranks.
