I am looking to buy a new flex head for my 2188 before harvest next fall. I'm having a hard time spending so much money on another 1020. Does the 2020 work on the older combines? I have heard that they don't feed well. If thats the case i don't want to buy a problem. My local dealer has a 2003 36' Macdon flex draper. It looks OK but not sure if its worth $23,500.
