High-power tractor - supporting agricultural implements are evolving rapidly amid the demands of large - scale agricultural operations, technological innovation, and environmental protection. Their development trends mainly focus on intelligence, integration, specialization, localization of core components, and green transformation.
The specific manifestations are as follows:
Intelligent upgrading for precise operations
Integration of intelligent control systems: Supporting agricultural implements are increasingly being equipped with electronic control modules that are compatible with the intelligent systems of high-power tractors. For example, planters and plows matched with CVT (continuously variable transmission) high-power tractors can achieve automatic adjustment of seeding depth and plowing depth based on real-time data such as soil compactness and crop growth stages.
Taking Weichai Lovol's P7000 CVT intelligent tractor as an example, its supporting agricultural implements can be controlled by a 12-inch intelligent terminal. This enables functions like remote monitoring and automatic control of multi-way valves, and realizes straight-line tracking with an accuracy of ±2.5 cm with the help of Beidou navigation, which enhances land utilization rate.
Development of unmanned operation matching tools: With the gradual popularization of 5G remote control and unmanned driving technologies for high-power tractors, supporting agricultural implements are also moving towards unmanned collaboration. For instance, the driverless models of YTO's large - horsepower tractors can be matched with intelligent seeders and power harrows.
These can complete plowing, sowing and other operations through ultra-long-distance remote control, and have been applied in many unmanned farm demonstration projects. In addition, agricultural implements such as boom sprayers are also integrating crop detection sensors to automatically adjust the spraying amount and range, which improves the precision of pesticide and fertilizer application.
Functional integration to improve operational efficiency
Integration of multiple operation links: To meet the needs of large-scale and efficient agricultural production, more and more supporting agricultural implements are integrating multiple functions.
For example, the integrated sowing and fertilizing machine has upgraded from simply combining sowing and fertilizing to integrating soil preparation, furrowing, sowing, fertilizing and soil covering. This completes the whole process of pre-planting operations in one go.
There are also cotton pickers that integrate picking, compression and baling. A single machine can replace the manual labor of 1,500 people, which greatly reduces the number of machine transfers and improves the overall operation efficiency.
Compatible with multi-crop operations: High-power tractors are often used in complex planting scenarios.
Their supporting agricultural implements are developing in the direction of strong compatibility. For example, the supporting headers of large grain harvesters can be replaced to harvest wheat, corn, soybeans and other crops. Some rotary tillers and harrows can also adjust their working width and tooth spacing according to different crop planting densities, realizing "one machine for multiple uses" and reducing the purchase cost of agricultural machinery for operators.
Specialized customization for diverse scenarios
Adaptation to large - scale field operations: For the high-load operation scenarios such as deep ploughing and subsoiling in northeast and northwest China, supporting agricultural implements are developing towards large size and high strength.
For example, the hydraulic reversible plows and subsoilers matched with 200 - 320 horsepower tractors have increased their plowing depth to 30 - 50 cm. They can break the compacted soil layer while ensuring operational stability, which meets the needs of soil improvement in large-scale farmland.
Development of tools for segmented scenarios: Aiming at the characteristics of fragmented plots and many slopes in hilly and mountainous areas, enterprises have developed supporting agricultural implements with small turning radius and strong climbing performance. For example, the supporting rotary tillers and seeders of YTO's MH804M hilly and mountainous tractor have a narrow body design.
They can carry out curve operations according to the terrain and adapt to irregular plots. For special crops such as orchards and sugarcane, special sprayers with adjustable nozzles and segmented sugarcane harvesters have also been developed to solve the problem of difficult operation of large machinery in special planting environments.
Accelerated localization of core componentsPreviously, the core components of high-power tractor supporting agricultural implements, such as high-pressure hydraulic systems and precision electronic control valves, relied heavily on imports. At present, domestic enterprises are accelerating the independent research and development and localization substitution of key components.
For example, YTO has developed a power shift transmission system independently, and the supporting hydraulic turning plows and seeders matched with its 320-horsepower tractors have all achieved the localization of core components. Weichai Lovol's CVT tractor supporting agricultural implements have adopted self-developed multi-section dual planetary confluence transmission technology.
This not only reduces the product price by about 30% compared with imported supporting tools, but also makes the after-sales maintenance more convenient. The localization rate of core components in the field of high-power supporting agricultural implements is constantly improving, which breaks the monopoly of foreign brands.
Green transformation responding to environmental requirements
Low-emission and energy-saving optimization: With the full implementation of the non-road National IV emission standard, supporting agricultural implements are also being upgraded in coordination with high-power tractors to reduce energy consumption and emissions. For example, the optimized design of the transmission structure of rotary tillers and harvesters reduces the energy loss during operation. When matched with hybrid high-power tractors, the overall fuel consumption can be reduced by about 10%.
Eco-friendly operation design: In response to the demand for green agriculture, supporting agricultural implements are developing towards reducing environmental pollution. For example, mechanical weeding tools have been upgraded from traditional hoe-type to precision inter-row weeding machines. They can remove weeds without chemical herbicides.
Straw crushing and returning machines can crush crop straw into 3 - 5 cm segments and mix them into the soil. This not only solves the problem of straw treatment, but also increases soil organic matter content and achieves the recycling of agricultural waste.
Extended service to enhance overall valueLeading agricultural machinery enterprises are no longer just selling supporting agricultural implements as independent products. Instead, they are combining them with tractors to provide integrated solutions including agronomy, machinery and intelligence.
For example, they provide customized operation parameter settings for supporting agricultural implements according to the local soil conditions and crop varieties.
They also provide long-term services such as remote fault diagnosis, maintenance and repair of agricultural implements. This transformation from selling products to selling services makes the matching between high-power tractors and supporting agricultural implements more efficient and reliable, and also enhances the market competitiveness of enterprises.
