We were able to speed up the sickle by changing the pulley on the driveshaft to the wobblebox. Found the pulley in the salvage yard off an older series III header. Also we were running SCH pro drive box. This box can stand a few more rpm than the standard wobblebox.It helped in drought beans at high ground speeds(6 mph). If you are feeding good at 3 mph the standard box should be plenty fast. As far as the air reel goes it will feed better but will increase the load on the feeder house clutch. We got two before we figured that one out. I would think the 40 would handle a 20 ft. at 3 mph ok unless the beans were green stemed real bad.
