There are two heads available.  Both were put together by Clarke in South Dakota.  40 series units w/ fluted rolls.  One head has short poly the other has long poly.  These heads have been well maintained.  New chains, sprockets, and idlers before fall harvest 14'.  Heads are set up with telescoping small 1000 drive lines and have been run on 9660 walker combines.  There is a head trailer available as well...  Upgrading to larger heads to accommodate row pattern needs.  Thanks for looking.
