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, reliable, 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.

Furthermore...
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. The Hillco 3700S Sidehill model raises the combine 5 inches to achieve maximum leveling. Additionally the 3700S can be fitted with ballast weight plates to balance your combine when equipped with today's larger headers.

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 Terrain Tracker sensors and enjoy the superb performance of fully automated lateral tilt and height control.

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 Case-IH combine. The 3700S Sidehill model extends the feeder chain and provides excellent feeding in all crops.

Powerful and Efficient
The leveling system's hydraulics are integrated into the combine's auxiliary hydraulics circuit for ease of maintenance and excellent reliability. Carefully engineered to maximize performance and minimize horsepower consumption, the Hillco Leveling System delivers power and speed to keep your Axial Flow combine agile and responsive in the steepest hillside terrain.

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.
