For the premium-middle class range from Claas, the Tucano range the status of the world-class acting sponsor, Lexion. The Claas Tucano 430 combine harvester was the smallest model of the Tucano 400 range until 2013 and compared to the much smaller 300 range, offers some advantages. Since 2013 the 430 has been powered by a Mercedes-Benz 6-cylinder in-line engine with 7.7 l cubic capacity. The reliable engine brings the Claas Tucano 430 combine harvester to a maximum performance of 210 k/W (286 PS) and meets the exhaust emission standard tier 4. A big advantage of the 400 range, compared with the 300 range, is that Claas has built in the extremely efficient APS threshing system. Through the APS-system in the Claas Tucano 430 combine harvester an acceleration of the crop takes place before the actual threshing process. Through this acceleration the crop is evenly distributed. The already effective centrifugal forces already separate 30% of the grains. These are collected in a separate basket which allows for clear unloading of the main basket and ensures that the fuel consumption of the Claas Tucano 430 combine harvester remains the same, despite a performance increase of up to 20%. The threshing itself is effected by means of a drum with a 450mm diameter. The residual grain separation of the Claas Tucano 430 combine harvester is disposed by six straw walker racks and four steps. A separating surface of 8.75 m2 arises from this. The purification follows is effected by means of a 6-fan turbine in the 430 with electrical fan adjustment. The grain tank of the Claas Tucano 430 combine harvester has a capacity of 9000 l and has a drainage capacity of 105 l/s. The Tucano range is optimally fitted out with the Claas 4-TRAC 4-wheel drive system. This allows it to be operated from the driver's cab without the clutch or change gears. Also in the Claas Tucano 430 combine harvester there is the central control system from Claas, the CEBIS. This allows the grains to be monitored and setting variations on the engine to be conveniently adjusted.
