Most likely the tax credits for "wind energy" ran out of this division making it an ideal time for Deere to sell this business.

We've probably seen the end of new wind energy projects in the near time, with lots of trading back and forth of current wind farms. If not the end of new wind energy projects, certainly a lot fewer.
