In addition to the automatic navigation and obstacle avoidance system, the high precision of 260HP tractors is also contributed by the following features and technologies:
High-precision Positioning Systems: Many 260HP tractors are equipped with high-precision positioning systems such as Beidou or GPS.
For example, the Dongfeng Hong LZ2604 is equipped with a Beidou navigation system, and its positioning accuracy can reach ±2.5 cm, which can effectively avoid missed and repeated plowing, improving the utilization rate of seeds, fertilizers, and land. The Case IH AFS Connect Puma 260 is equipped with the AFS vector pro receiver, and with the AFS accu guide auto guidance technology, its accuracy can reach 1.5 cm when using RTK+.
Intelligent Transmission Systems: Some tractors are equipped with intelligent transmission systems, such as the German ZF AMT automatic shifting system on the Dongfeng Hong LZ2604. It has 40+40 gears that can be switched seamlessly, covering a full - speed range of 0.3-36.8 km/h.
The HP2604 - G is equipped with an electronically controlled wet clutch system, which realizes clutch - free shifting through electro - hydraulic control technology, and its intelligent control system integrates intelligent shifting and one - button headland operation functions.
These intelligent transmission systems can provide the most suitable power output according to different operating conditions and requirements, ensuring the precision of tractor operations.
Precision Hydraulic Control Systems:
The closed - center load - sensing hydraulic system is commonly used in 260HP tractors, such as the Dongfeng Hong LZ2604 and the Case IH AFS Connect Puma 260.
The closed - center load - sensing hydraulic system of the Dongfeng Hong LZ2604 has a large flow output of 152L/min, and is equipped with 4 groups of electronically controlled hydraulic valves, which can support the synchronous operation of subsoilers and balers.
The hydraulic output flow of the system can be adjusted, and the flow size of each group of hydraulic output valves can be adjusted through a knob according to different operating needs, realizing the simultaneous output of different hydraulic powers.
This precise hydraulic control system can ensure the stable operation of agricultural implements and improve the precision of operations.
Advanced Engine Control Technology: The engines of 260HP tractors usually adopt advanced control technologies, such as the YTN9 six - cylinder high - pressure common - rail engine equipped on the Dongfeng Hong LZ2604.
The engine has a torque reserve of more than 30%, which can intelligently adjust the power output according to the operating needs, ensuring that the tractor can maintain stable power output during operations and providing a powerful power guarantee for precise operations.
The engine power management technology of the Case IH AFS Connect Puma 260 can increase the engine power to 302HP for PTO, hydraulic, and transportation applications.
