Case IH Axial-Flow

Engineering for Gentle Threshing

The core of the Case IH Axial-Flow lies in its single-rotor threshing concept, which remains the gold standard for cereal harvesting. Unlike traditional straw-walker systems, separation here occurs via centrifugal force, achieving a minimal grain damage rate. The rotor is the heart of the combine; its variable-pitch flighting design ensures a smooth flow of material, reducing peak engine loads and preventing cylinder plugging when working in high-moisture field patches.

Cross-Flow Cleaning System

A combine's efficiency is determined not just by throughput speed, but by the quality of grain in the tank. Axial-Flow models utilize an active cross-flow cleaning system. The practical benefit? The system automatically compensates for combine tilt when working on slopes, leveling the airflow across the entire sieve area. This eliminates grain buildup on one side and ensures purity, which is critical for meeting elevator grade requirements.

Fuel Efficiency and Power Plant

The FPT Industrial engines powering the Case IH Axial-Flow are integrated with an intelligent power management system. Instead of maintaining constant RPMs, the automated system adapts the load based on actual rotor resistance. This yields two practical advantages: a significant reduction in diesel consumption per hectare and extended oil change intervals due to the engine operating in optimal thermal regimes.

Practical Takeaways for Farmers

• High throughput while preserving straw integrity: Axial-Flow maintains stem structure, which is beneficial for subsequent soil preparation.
• Modular design: Easy access to the rotor components and the unloading auger significantly reduces daily maintenance downtime.
• In-cab rotor speed adjustment: Allows the operator to react instantly to changes in crop moisture levels throughout the working day.
