I hear good things about the New Idea design cutterbar which,I'm thinking, might have been in the 5408 Agco and Hesston 3309.Hopefully,someone will correct this if it isn't right.
New Holland 616 is.I think,a Kuhn made cutterbar.I believe that is the number of the disc mower we had once.Cut well but could never get it to cut high enough stubble to suit us.Don't know if high skids were available or not.Kuhn design uses a common sump and you would need to let the fluid flow back to the end cutter when lowering from vertical before engagement of the PTO to keep from running it dry.I think the New Idea had individual pods.
