2025.07.21
Recently, the PT320 power-shift tractor transmission—developed independently by HAGG—has successfully completed full-vehicle installation and debugging at a major OEM plant. Its outstanding performance has earned high praise from customers. The successful application of this product marks another significant milestone for Hangchi in the field of high-horsepower tractor transmissions.
This transmission is compatible with large tractors ranging from 320 to 360 horsepower. It features an integrated axle and gearbox design, offering 48 forward gears and 24 reverse gears. The primary transmission system employs a 6-speed power-shift mechanism controlled by electro-hydraulic proportional valves, ensuring uninterrupted power delivery and enabling seamless continuous operation while significantly enhancing fuel efficiency. The product comes equipped with multiple modes, including creep mode, differential lock, and two-wheel/ four-wheel drive options, which greatly reduce the driver’s operational workload. Additionally, its "smart-level" automated control and "precision-level" speed adjustment allow for accurate adaptation to various agricultural tool conditions, making it well-suited for diverse and challenging working environments.
The PT320 transmission perfectly aligns with China's strategic direction for developing high-end agricultural machinery, meeting the industry's growing demand for tractor upgrades. By simultaneously enhancing operational efficiency and maintenance cost-effectiveness, it demonstrates robust core competitiveness and is poised to become a benchmark product in tractor transmissions—providing strong support for upgrading China's advanced agricultural equipment.
