Hillco Leveling Systems are packed with a long list of industry leading features and benefits such as true bolt-on design, fully automatic variable speed leveling, and fully automatic header height and lateral tilt control.Other benefits include increased hillside capacity, reduced hillside grain loss, improved sample quality, and comfortable hillside operation.Additionally, Hillco guarantees that your combine's original Case-IH warranties will remain in full effect after installation of your Hillco Leveling System. If you harvest in the hills, there is no better investment you can make than equipping your new or used Case-IH combine with a Hillco Leveling System. We offer a complete line of leveling systems for Case-IH combines that insure excellent hillside performance in an economical, bolt-on package.


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.


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.


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.

Why should you invest hard-earned dollars on a Hillco Leveling System for your combine? We believe you shouldn't have to sacrifice your combine's full potential just because you harvest in the hills.

Grain Savings
Harvesting with a Hillco Leveling System means you remain level at all times; putting all of the grain in the tank instead of leaving it on the ground. We don't expect you to take our word for it... we've had extensive field testing done to quantify how much grain you are actually losing when you are running a level-land combine in the hills.

Increased Productivity – More Acres per Hour
During harvest, time is money. So why buy a new combine and then sacrifice up to half its capacity in the hills? The technology incorporated into Hillco Leveling Systems eliminates the need to reduce sidehill harvesting speeds and is a perfect complement to today's powerful combines.

Lower Operating Costs
Many harvesting expenses are related to the time it takes to harvest.

  • Labor: shortening your harvest equals fewer man hours required for combine drivers and other harvest personnel.
  • Fuel: shortening harvest time means harvesting equipment is running fewer hours.
  • More time for more acres: The hours saved with the combine's increased capacity in the hills means there is more time for more acres without having to purchase another combine.
  • Get it in the bin: The longer the crop stands in the field the greater the exposure to weather and the risk of dry down. Being able to get the harvest out a week early can add tens of thousands of dollars to your bottom line.

Warranty Agreements
Hillco has warranty agreements with all major North American combine manufacturers ensuring that the installation of Hillco Leveling Systems does not affect the existing combine warranties.

Fewer Combine Hours
Faster harvesting speeds mean fewer hours on your combine and that equals greater value at trade-in time.

Annual Cost of Ownership
A Hillco Leveling System retains an average of 60% of its original value whether it is 5 or 15 years old.

Operator Comfort
No one buys a leveling system based on comfort, but it is one of the main reasons people give for never operating a level-land combine in the hills again.

Keeps Grain Tank Level
With the combine level on your hillsides, you will be able to fill your grain tank to capacity.

Easy Installation
The unique bolt-on design of Hillco Leveling Systems makes dealer installation a convenient option for both new and pre-owned combines.
