We have a '03 2388 and for this upcoming year we bought a new 12r22" Geringhoff RD for it. I have heard that I will want to put a weight bracket and possibly solution in the back tires. But what other modifications are necessary to get the desired performance out of both? Does anything need to be done to the feeder house drive? What about boosting the power?

I have ran a 2588 with a 12 22 Geringhoff for Johnson Harvesting. I don't think that weights are necessary, if you have 4wd and large tires. Yes your backend is a little light, but it never bothered me with all the acres I went over with the head. If you have a tendency to stop really quick and dont like having your backend off the ground go ahead and add weights. As far as power the more the better. The more power you can get the better you will like the combine and the head.

you are going to want as much weight back there as possible. We ran an 8row 30'' geringhoff (non chopping) head on our 2388 one year and it was really light on the back end. No added weight and no 4wd... can't remember if we had fluid or not.

We borrowed our neighbors 12row 20'' head to take out a plot and our combine couldn't lift the head all the way up.

If its not a 12 row ready combine you will probably need to add another lift cylinder to the feederhouse.

We ran a 2188 on a 2212 12 row 20in head for a year and a half. We had both back tires full of fluid and eight weights on the back. In the hills you had to be carefull but it worked. We also put on a third cylinder for the feeder house.

ok, thanks for the input thus far. Sounds like weight in the back end is a must as well as a third lift cyclinder. Is there anything that needs to be done to the header drive system coming off of the combine (oil cooler, etc.)? I've heard the Deere guys have to put on a heavy duty feeder house drive and coolers. What kind of ground speed can I expect?

We ran a 2388 for 3 years with a 2208 and we had to put weights on the back for that, then we went to a 8 Geringhoff and I will say it wasnt any lighter. If your machine is a twelve row ready you are lucky, otherwise I would even add an extra lift cylinder under the feederhouse. I know I could still get the back of the machine up in the air if I stopped suddenly or even drove though a steep water way.

If you get a chance to put the cone, or funnel over the clean grain auger under the bottom sieve it will help with the extra volume of corn going to the elevator as well as improving the grain quality. 12 row ready 2388 machine already have it installed.

Make sure that your lower drive belt on the feederhouse is tightened all the way and a little more. This will help some when conditions get tough.
Your speed will depend on the corn itself (height, stalk strength, yield). The Geringhoff RD heads like green stalks. Your speed will be dependent on the combines power as well.

We have ran a JD1293 (12 row 30in.) the past 3-4 years. We added a set of front-end weights from a magnum (1800lbs) and put fluid in the tires. You really have to try to get the tires off the ground. with 3 cylinders, lifting is no problem. They put a heavier spring on the feeder drive belt on the right hand side of the combine, just in front of the right wheel. Don't know if weight is as much as a 12R20in. G-off, but that's what we do, and it works well.
Also, someone mentioned the cone or cylinder under the shoe, never heard of that, but maybe something i should do.
