The agricultural 1504 tractor with an enlarged rear axle is a high-powered four-wheel-drive agricultural machine mainly used for heavy-duty operations such as large-area land reclamation and deep plowing.
The Dongfanghong LX1504 is a typical and well-performing model of this type. Its core advantages lie in the enlarged rear axle, strong power configuration and excellent operation performance, which are well-suited to the harsh requirements of land reclamation and plowing projects.
Core Advantages of the Enlarged Rear Axle
Enhanced Load-Bearing and Traction Capacity: The 1504 tractor is designed with an enlarged and reinforced rear axle (some models adopt the TC series enlarged rear axle).
Compared with ordinary 150-horsepower tractors, it has a more robust structure and higher load-bearing capacity. When equipped with heavy-duty implements such as deep plows and land reclamation rippers for operations like breaking compacted soil layers and reclaiming wasteland, it can effectively bear the huge resistance from the soil.
Moreover, the matching wheel-side reduction structure further enhances the torque transmission efficiency, ensuring that the tractor does not lose power when facing sticky soil or gravel-covered land during reclamation.
Improved Operational Reliability and Durability: The enlarged rear axle optimizes the internal gear and bearing specifications. It is equipped with a chassis lubricating oil radiator and a forced lubrication system.
This can effectively control the temperature of the transmission system during long-time continuous land reclamation and plowing, reduce wear and tear of components.
At the same time, some models adopt a split-type power output assembly structure in the rear axle area, which facilitates the disassembly, assembly and maintenance of key parts, reducing downtime and improving the continuity of engineering operations.
Power Configuration for Land Reclamation and Plowing
The tractor is equipped with a Dongfanghong 6A series six-cylinder high-pressure common rail turbocharged intercooled diesel engine, with a rated power of 110.9kW (equivalent to 150 horsepower). Its torque reserve exceeds 30%, and it can output strong power stably even under low-speed heavy-load conditions.
For example, when plowing the black soil in Heilongjiang or the compacted dryland in Weibei, it can easily achieve a plowing depth of more than 15cm. Some users can complete the plowing of 150 mu of land in 10 hours of continuous operation.
It is equipped with a 380-liter side-mounted fuel tank and adopts a three-stage fuel-saving frequency conversion design. Combined with the multi-power fuel-saving switch, it can adjust the power mode according to different operation intensities.
This not only reduces fuel consumption during land reclamation and plowing but also ensures long-time operation without frequent refueling, which is very suitable for large-area continuous engineering operations.
Adaptability and Operational Performance in Engineering Operations
Rich Gear and Speed Options: It is equipped with a 24-forward and 8-reverse gearbox with a crawling gear, and the minimum speed can be as low as 5 meters per minute. This ultra-low speed is particularly suitable for fine operations such as leveling the land after reclamation and sowing preparations. Meanwhile, the four-wheel drive and two-wheel drive can be switched freely.
The front axle adopts an enlarged and maintenance-free dry-land front axle, and the tires are 14.9-26 front and 18.4-38 rear Jiazi tires, which have strong grip and can adapt to complex terrains such as hillsides, wastelands and muddy fields during land reclamation.
Strong Matching with Multiple Implements: The tractor has multiple power output speeds such as 540/720 and 540/1000 r/min, and can be equipped with 6-key, 8-key and other shaft heads. It can be matched with a variety of engineering and agricultural implements required for land reclamation and plowing, including deep plows, rotary tillers, land reclamation rippers, etc.
In addition, it is equipped with a strong-pressure lifting device with two auxiliary oil cylinders, which can easily lift heavy implements and realize the free switching between strong-pressure and non-strong-pressure states, adapting to the operation needs of different soil layers and landforms.
User-Friendly Design for Engineering Operations
It is equipped with a luxurious six-column cab with a suspended shock-absorbing seat and an adjustable steering wheel.
The cab has good heat insulation and sealing performance, and is equipped with air conditioning and side air outlets, which can reduce the driver's fatigue during long-time land reclamation operations.
The 7-inch LCD color screen can display the working status in real time, and the integrated rearview image function is convenient for the driver to observe the operation of the rear implements and ensure the quality of plowing and land reclamation.
It supports optional 3 or 4 groups of hydraulic outputs, which can be matched with compound implements, and can also be equipped with front push shovels and buckets.
This enables it to complete a series of supporting operations such as land leveling and debris cleaning while carrying out land reclamation and plowing, improving the overall efficiency of agricultural engineering.
