Claas Tucano 440

The APS Threshing Principle: Efficiency Through Physics

The core of the Claas Tucano lies in its APS (Accelerated Pre-Separation) threshing system. By placing an accelerator drum before the main threshing cylinder, the machine speeds up the crop mass to 20 m/s. This creates significant centrifugal force, allowing up to 30% of the grain to be separated before it even reaches the main cylinder. In field operations, this results in a gentler treatment of straw and drastically reduced load on the straw walkers, ensuring higher throughput even in dense, high-yield crops.

Intelligence and Adaptability

For demanding harvesting conditions, the Hybrid models integrate ROTO PLUS rotor separation, which is indispensable for wet or lodged crops. The machine's intelligence is managed by the AUTO CONTOUR system, which utilizes high-precision pressure sensors to allow the header to track ground contours seamlessly. The onboard CEMOS system continuously monitors grain losses and sample purity, automatically suggesting adjustments for fan speed and sieve openings, which allows the operator to maintain peak efficiency regardless of daily moisture fluctuations.

• Large grain tank capacity (up to 10,000 liters) minimizes downtime for unloading.
• Mercedes-Benz engine architecture provides consistent torque at low RPMs, significantly reducing fuel consumption.
• The VISTA CAB design provides an unobstructed view, crucial for operating wide headers safely.

Claas Tucano occupies a unique niche, offering the robust threshing power of a larger combine within a more compact and maneuverable chassis. The drivetrain and service access points are designed for longevity, allowing for intensive, around-the-clock operations during the harvest window. It is a workhorse built for durability and ease of maintenance in any farming environment.
