John Deere 635D Draper Header

The 635D has a true 35-ft cutting width and the unique draper-style crop cutting system delivers the high-capacity feeding required of the high-capacity STS Combines.

The 635D Draper Platforms increase 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.

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