Claas Mega

APS System: The Science of High Throughput

The core of the Claas Mega is the Accelerated Pre-Separation (APS) system. By introducing an accelerator drum before the main threshing cylinder, the machine speeds up the crop flow to 20 m/s. This creates a centrifugal effect that thins out the mat of straw, allowing the grain to pass through the concave at a higher velocity. Practically, this translates into a 30% increase in throughput without requiring a larger drum diameter, making it ideal for high-yield conditions or heavy-duty harvesting.

Advanced Separation and Straw Quality

Following the main 600 mm drum, the Mega features an additional discharge beater with a secondary concave. This setup serves two purposes: it ensures the complete separation of grain from straw and allows the main drum to operate at lower RPMs. This combination is essential for reducing grain cracking and maintaining straw integrity, which is a major advantage for farms focused on straw collection for livestock or bedding.

3D Cleaning and Slope Management

The cleaning system utilizes a 3D sieve design capable of handling slopes of up to 20%. The parallel-kinematic drive compensates for cross-slope lateral movement, preventing grain loss and ensuring an even distribution of material across the sieves. This, paired with a high-performance turbine fan, eliminates 'dead zones' in the cleaning process, ensuring that the grain reaching the tank is consistently clean regardless of terrain.

• Hydrostatic ground drive allows for precise, stepless speed control during harvesting.
• Mega-Trac architecture provides a reinforced axle design, handling the dynamic loads of a 7-8 ton grain tank.
• The integrated Claas monitoring suite gives operators immediate feedback on loss rates and engine load, enabling real-time adjustments.
