you need 3 cylinders on the feeder house if you don't already. And you'll need weight in the back. maybe not as much if you have rear wheel assist. they also put an updated or 'heavy duty' feeder jackshaft tightener as well as feeder house drive tightener. it may be standard equipment on 2388, though?our 2188 has two sprocket choices on the clean grain elevator, if yours does, make sure it's on the faster one. i'm no expert, but these are the things i've dealt with so far. if our 2188 does it, i know yours will. good luck to you.
