New Holland vs Case IH: Which Combine for Sunflowers

Harvesting sunflowers is a serious test for equipment. Fragile heads, large amounts of oily residue that clogs separation, and a high fire risk all demand precise combine settings. Two market leaders from CNH Industrial - New Holland and Case IH - take different approaches to threshing. Let's break down which technology suits sunflower fields best.

Design Differences in Threshing Systems

The main difference between the brands lies in rotor architecture, which directly affects working speed and threshing quality.

New Holland (CR Series)

New Holland's rotary models are built on Twin Rotor technology - two longitudinal rotors of smaller diameter.

• High centrifugal force: two rotors spread the crop mass in a thin layer, allowing fast, high-quality seed separation at higher ground speeds.
• Flexible adjustment: the system allows precise tuning of rotor speed and concave clearance, gently rubbing seed out of the heads while minimizing sunflower seed hulling.

Case IH (Axial-Flow Series)

Case IH uses the single-massive-rotor philosophy, unchanged for decades.

• "Grain on grain" principle: threshing happens through crop material rubbing against itself rather than hard impacts, reducing the percentage of cracked sunflower seed in the tank.
• Simple construction: a single rotor means fewer moving parts, belts, and gearboxes, which simplifies field maintenance.

What Matters When Harvesting Sunflowers

Handling wet crop mass and cleaning

Sunflowers are often harvested when the heads are already dry but the stalks remain wet and green. Under these conditions, load on the sieves becomes critical.

New Holland has the edge on fields with challenging terrain thanks to its Self-Leveling sieve system. The sieves stay level on slopes up to 28 degrees, preventing crop shift and ensuring a clean tank.

Case IH's Cross Flow system works efficiently with dry crop mass. However, if the stalks are too wet, the single large rotor can shred them into chaff that clogs the sieves, requiring the operator to fine-tune fan airflow manually or automatically.

Automation and safety

Sunflower moisture swings sharply throughout the day - from morning dew to midday heat. Automation systems (IntelliSense on New Holland and AFS Harvest Command on Case IH) adjust the machine's settings every 20 seconds, automatically changing clearances and fan speed.

On fire safety - critical given the flammable sunflower dust - Case IH has a slight edge. Thanks to the Axial-Flow's simpler under-hood layout, there are fewer nooks where dust can accumulate and pack. That said, shift-by-shift compressed-air dust removal is mandatory for both machines.

Bottom Line: Which to Choose

Both combines are highly effective, but built for different farming conditions.

Choose New Holland if your fields have uneven terrain, hills, or if you frequently work in higher-moisture conditions. Its more complex twin-rotor system and sieve leveling deliver maximum grain cleanliness.

Go with Case IH if you have large, flat field blocks and are looking for the simplest, most reliable, and easiest-to-service machine. The single-rotor Axial-Flow system rewards you with gentle threshing, a minimal cracked-seed percentage, and high productivity on dry fields.

Whichever brand you choose, you'll find spare parts and service support for both New Holland and Case IH at Marian Agro in Ternopil.
