5XZD-15AC Grain Cleaner & Grader is jointly designed and developed by us and the Australian company FRAHN ENGINEERING. Advantages: 1. Uses four truck tires and truck suspension systems, can connect Australian pickup trucks, driving at 80 km/h. 2. Two isolated sieving trunks installed together design (one sieving trunk added a middle partition to become two isolated three-layer sieving trunks), the output capacity doubled. 3. All electrical components meet Australian standards (the most stringent in the world) 4. The design of a hydraulic rod added to 150 kg grain output box can enable a single person turn up the entire output box. This can decrease the time for replacing the sieves and save labors. On the client side: Well-loved by Australian and American farmers, their farms are in great need of equipment that can move at high speeds, and the capacity of production required is also very large. This equipment is just right for the needs.
