Have been around several yes they are building 5100 in March. About 2000 to 5000 dollars between MacDon and AGCO depending on dealers and setup. Check on all updates if you have an older head 05 will come with them.
There are very few Agco draper headers in our part of the woods in Victoria, Australia but we know of 3 of these Agco drapers that have gone up in flames during this last season, taking a combine or two with them. We think there may be a problem with dry straw packing in around the rollers or somewhere under the belts and then friction sets them on fire. Have not heard of any similar problems with the other makes. Cheers.
I saw a new 36ft Macdon flex head working in 70 bushel irrigated soybeans. I don't think the gleaner flexes as much as it floats. It would compare more to the 970 Macdon, and I don't think Gleaner or Macdon recommended cutting soybeans with their older series heads. You need to ask your dealer!
