I would go with the Case. There has to be a reason that there are rows of JD rotors on the lots and the walkers disappear immediately. The Case has been proven since the late 70's.
We run a combine rotation and we get a new one each year and run a 3 year old We have never had any trouble in 8 years of this with the combine and the 3rd year is always minimal Im very happy with the 2388's and its really hard to beat something that reliable. I do wish they would get a bigger hopper uptop but i'll live either way
