AVP_Matt - 10/18/2022 08:08 Gearboxes aren't even the same from an early to a late 2200. There's a serial# break somewhere around 2004 that updated the gearbox. It would include the last few HAJ #s and all the CBJ #s if anyone is shopping. We just got a 2208 with the late gearboxes and second iteration of the row unit slip clutch and its been trouble free so far. It has the full Calmer kit now and for the most part I love it. About the only issue we're having is it's leaving things a bit scraggly in goosenecked corn. I was also told ahead of time the Calmer rolls work best when the stalk either has life yet or completely dry. They'll be a little subpar when the stalk is rubbery after a killing frost. So far I'd say it's pretty accurate but not as bad as I was prepared for. Anything above where the stalk is cut off is still obliterated.

Baby Robin - 10/17/2022 23:44 I’m with Baby Bull on 2208 series head ranking as 1 of the worst heads. If your terrain allows your 2388 to shell 200+ bushel corn at 7-8 mph, maybe… just maybe they fit. They head shell something fierce with corn less than 17-18 percent because there is only fast and super fast setting in the gearboxes off the feeder house shaft. We snapped off the driver sprockets on the snap roll gearboxes all the time - maybe 2-3 a season in the cold weather. They were a new Holland head that was painted red…. New Holland’s have variable speed feeder house drives like the old 6600 and 7700 series John Deere combines….. if you could vary your feeder house speed with an 88 like their yellow siblings- they might work. They are cheap for a reason…..
