Feederhouse / Contour-Master™

Heavy-duty feeding for high-yielding crops

Your need for greater harvesting capacity continues to drive innovation at John Deere. An excellent example is our high-performance 4x4 feederhouse. An innovative design delivers a 15-percent increase in feeding capacity –without slugs. It sends a consistent, smooth crop mat into the combine every time. Durability was designed into this feederhouse, too. The slats are heavy-duty, heat-treated cast iron, so they can stand up to the biggest challenges your header equipment can throw at them.

And speaking of headers, this feederhouse came by its 4x4 name honestly. It can lift 4400kg (or 9,700 pounds) and carry up to a 40-foot cutting platform! All of the feederhouse components complement the CommandTouch multi-speed feederhouse drive. Designed to handle the 600C 12-row StalkMaster Chopping Corn Head, the CommandTouch drive is standard on all 9870 STS corn combines. It’s optional on all 9770 STS combines and on 9870 STS rice and grain combines.

Pivot point ensures consistent down pressure.

1. This high-performance feederhouse features a unique pivoting mid-frame and front drum design that provides constant, heavier down pressure on the crop material entering the feederhouse. This results in faster, more even feeding and increased capacity at high ground speeds. 2. The CommandTouch Multi-Speed Feederhouse Drive provides the high torque needed to operate 12-row StalkMaster Chopping Corn Heads. It’s powered through a fi ve-speed wet-clutch power-shift transmission. Select any speed from 495 to 747 RPM on-the-go. Speeds are spaced at distinct “steps” to better match gathering speed to ground speed. 3. The fi xed-speed feederhouse drive is standard on all STS grain combines. It features a 520-RPM drive to optimize combine performance. 4. The all-crop variable-speed feederhouse with Posi-Torq™ Drive is standard on 9570 STS, 9670STS, and 9770 STS corn combines. It’s available with regular, heavy-duty, or high-torque drive.

Let Contour-Master Take Control of Header Tilt

Harvest more grain at faster speeds – in any terrain. Contour-Master is a self-leveling system that allows the feederhouse and header to tilt 4 degrees side-to-side for exceptional ground following. Sensors on fl ex platforms and corn heads detect changes in the terrain and signal the Contour-Master controller. Tilt response is instantaneous. The benefi t? More consistent cutting height across the platform width, without bulldozing or gouging. And because you can harvest at faster speeds on sloping terrain, you’ll maintain your productivity.

Unlike add-on designs, the tilt frame is an integral part of the

feederhouse – not an afterthought. So there’s plenty of backbone to carry 12-row corn heads and 40-foot platforms, and exceptional strength to withstand the heavy “racking” loads generated by rapid tilting action. What’s more, the feederhouse is the same length as a standard feederhouse, maintaining visibility to the platform. There’s no compromise in feeding either, as with add-on designs that increase feeding distance and hamper material fl ow.

Activate the Contour-Master

system with the Active Header Height Control display. It constantly displays feederhouse tilt, making it more convenient when centering the platform.
