John Deere 640D Draper Header

The 640D has a true 40-ft cutting width and the unique draper-style cutting system delivers high-capacity feeding that is required of the high-capacity STS combines.

The John Deere 640D Draper Platforms provide for increased combine productivity in small-grain and rice harvests.

The draper belt system ensures smooth, uniform feeding of crop to the feed drum and the combine feederhouse.

Durable, high quality split reel enables greater performance at larger width, helping to achieve the best process in crop flow and feeding capacity.

Ideal for harvesting crops where additional cutting platform productivity is desired.
