I don't know how new you want but I have a 36 ft Mac Don 960 draper (1995) with transport_gauge wheels, pickup reels, and JD adapter. $14,000 I think a brand new MacDon is close to $35,000. You can try Greensburg Tractor in Kansas.
We have ran 936 D in the past on our John Deere, but I was thinking of switching over to Mac Don. Because we have ran into some trouble with the ones that we got. I just wondering how they compared. I have not ever ran a mac don header, so I was just looking for any input.
