Could not tell you about the JD draper, but have lots of experiance with the McDon. We use a 36 ft. McDon on our 9600, harvesting peas, wheat, barley, flax, oats, etc. We have pick up reels and also lifters on this header. The feeding of crops is excellant with this header, giving the cylinder an even feed. As for moving parts, you have to grease every day to be safe. If doing a lot of tough conditions with 36 ft., would suggest a double knife system. Up here in Sask. and Manitoba they are more common than the JD 930 ridged
