Thinking about trading choppers currently have a 10 series deere looking at moving to probably a 6850 have had 2 dealers suggest an 840 claas instead both have 24 knives. Was wanting a deere with 56 knives for earlage. One dealer said has adapter for running my 4500 kemper on claas and the othe one has 450 claas head which head is better. Any problems with the 840
