2970S Sidehill


2970S Sidehill2970S Sidehill - 18% Slope Compensation

For John Deere 9660-70, 9760-70,
& 9860-70 STS combines.

The Heart of Every Hillco Leveling System
We didn't try to reinvent the combine's drive system - we just moved it. In the past, the transmission to final drive power train on most leveling combines has been complex and expensive. The Hillco Leveling System moves the original transmission-to-final-drive assembly from the combine's main axle down to the leveling system's undercarriage. There are no extra or non-stock drive train parts, and the results are impressive. This efficient and reliable design keeps the tread face of the tires flat on the ground for increased traction and stability. You can even equip this leveling system with dual drive tires for the ultimate in stability and flotation.

2970S Sidehill Undercarriage

2970S Sidehill Rear Drop Axle

To compensate for the height increase the overcarriage/undercarriage adds to the combine chassis it is necessary to increase the height of the back of the combine. The function of the drop axle assembly is to balance the combine fore/aft. This bolt-on component is located between the combine's main frame and rear axle. After installation of the Hillco Leveling System the combine will be slightly shorter than a John Deere Sidehill combine. The Hillco Sidehill model raises the combine 5 inches to achieve maximum leveling.

No Cables!
Today's wider headers demand a better header control solution than yesterday's cables and pulleys. Hillco Leveling Systems are equipped with an advanced master/slave hydraulic circuit that coordinates rotation between the combine chassis, header, and ground to deliver the ultimate in ground hugging performance. You have the ability to manually override the master/slave hydraulic circuit to take care of those nasty terraces and other unusual ground contours. It also works great for tight maneuvering through gates and bridges. Equip your header with Contour Master sensors and enjoy the superb performance of fully automated lateral tilt and height control.

Sidehill Transition

A Voracious Appetite
Every Hillco Leveling System is equipped with a crop feeding system that ensures maximum throughput. Whether it's green, viney crops and weeds, or short slick straw conditions, Hillco Leveling Systems deliver the capacity you expect from your STS combine. The 2970S Sidehill model extends the feeder chain and provides excellent feeding in all crops.

Powerful and Efficient
The Sidehill's hydraulic circuit flow is developed from an independent gear pump mounted directly to the output shaft on the combine's rear engine housing. This isolates the leveling systems pressure functions away from the combine's main hydraulic circuits for improved reliability and simplified diagnostics. Carefully engineered to maximize performance and minimize horsepower consumption, this sidehill leveling system delivers power and speed to keep your STS combine agile and responsive in the steepest sidehill terrain. An optional premium pressure-flow compensated hydraulic pump is available for the ultimate in horsepower efficiency.

Digital Electronic Slope Control

Smooth Yet Responsive
Select the Automatic mode and the Hillco Leveling System's state-of-the-art electronic slope sensor and module provide the ultimate in slope compensation performance. The clinometer based slope sensor continuously monitors the sloping field conditions and maintains a combine chassis position within 3/4 degree of level. The variable rate technology utilized in the leveling controller and hydraulic control valve allows for infinite leveling speed control from zero to maximum speed. The further the combine is out of level the faster the system corrects and, as the combine chassis approaches level, the leveling rate slows. The variable speed leveling is what allows Hillco Leveling Systems to be smooth and responsive.

Cab Controls
The LCD display console delivers fingertip control of all leveling functions. Select Automatic mode and the leveling system corrects for slope changes without any operator input. Select Manual mode and the Automatic leveling is disabled, allowing the operator to have full control over the combine's chassis position. The Manual mode is especially handy for controlling unloading auger height. A Diagnostic mode makes electrical troubleshooting simple.
