How Does A Tractor Autosteer Work?

In traditional agricultural operations, tractors rely on manual steering, which can easily lead to operational deviations due to fatigue, lack of experience or changes in terrain, resulting in repeated tillage or omission of land, increased fuel consumption and waste of agricultural supplies. The application of automatic steering motors and automatic steering systems has enabled every inch of land to be precisely utilized and every drop of fuel to reach its maximum value.

How does the automatic steering of a tractor work?

The automatic steering system is specially designed for the application scenarios of four-wheel agricultural machinery such as tractors and harvesters. It can replace the traditional manual steering and enable agricultural machinery to accurately travel along the pre-planned route. Its core technologies include:

High-precision satellite positioning (±2.5cm error)

1. Auto steering systems can simultaneously receive signals from the four major satellite systems of GPS, Galileo, Beidou and GLONASS to ensure that stable and reliable positioning services can be obtained at all geographical locations.

2. By adopting RTK real-time dynamic differential positioning technology and integrating inertial navigation, automatic control, electric steering and other technologies, the centimeter-level positioning accuracy of agricultural machinery equipment is achieved, enabling it to travel along the planned route.

2. Auto steering motor

1. The motor is a brushless DC motor that meets strict three-proof requirements (dust-proof, moisture-proof, and salt spray-proof), with a protection grade of IP55. It ensures stable operation in harsh farmland environments such as heavy rain and sandstorms, providing reliable all-weather protection for intelligent agricultural machinery operations.

2. Supports RS232 and CAN bus communication, allowing real-time adjustment of the steering Angle to ensure precise control. At the same time, it integrates a high-precision encoder internally to enhance steering accuracy and provide a reliable guarantee for the stable operation of agricultural machinery.

3. The automatic steering motor adopts multiple intelligent protection designs to ensure the safe and stable operation of the system under various extreme working conditions, thereby enhancing the motor's adaptability and lifespan. The driver is equipped with built-in temperature monitoring and protection, which can monitor temperature changes in real time to prevent overheating and damage. It is equipped with overcurrent and overload protection to prevent damage to the equipment caused by abnormal current. It is equipped with overvoltage and undervoltage protection to ensure stable operation of the equipment when voltage fluctuates. It is equipped with motor short-circuit protection, which can promptly cut off the circuit to ensure safety. It also features locked rotor and runaway protection.

Why choose an auto steering system?

1. High precision: ±2.5cm error, far exceeding the accuracy of manual operation.

2. All-weather operation: Unrestricted by time and terrain, enhancing production efficiency.

3. Reduce labor intensity: Assist agricultural machinery operators, reduce the workload and intensity of personnel, and at the same time enhance the stability of long-term operations.

4. Quick installation: The auto steering motor adopts an innovative hollow shaft interface design, which can be installed in just a few simple steps without the need for complex modifications.

The ag auto steer system comprehensively covers the entire agricultural production process and is widely applied in various agricultural operation scenarios such as ploughing, harrowing, ridging, sowing, inter-row cultivation, spraying, and harvesting. Improve operational efficiency while significantly reducing labor costs, making precision agricultural production more intelligent, precise and labor-saving.
