The fan in a tractor is a key element of the cooling system that helps the radiator remove heat from the coolant. Its main task is to ensure adequate air flow through the radiator, which helps maintain optimal engine operating temperature.

Tractor fan functions:

• Engine Cooling: The fan increases airflow through the radiator, which allows heat to be effectively removed from the coolant. Thanks to this, the engine does not overheat and can operate at the optimal temperature.
• Cooling system support: The fan supports the radiator, especially when the tractor is operating in difficult conditions, such as high ambient temperatures or work under heavy load.

Common fan problems:

• Bearing wear: Fan bearings can wear out, leading to noise and vibration. In extreme cases, this may lead to the fan being blocked.
• Mechanical damage: The fan blades may suffer mechanical damage due to impacts or vibrations, which reduces its efficiency.
• Drive problems: The fan may be driven by a V-belt or directly by the engine. Belt problems such as belt wear, cracks or looseness can affect fan operation.
• Electric motor failure (if the fan is electric): On some modern tractors, the fans are driven by electric motors which can fail.

Fan Maintenance:

• Regular inspection: Regularly checking the condition of the fan, including the bearings, blades and drive, allows you to detect problems early and prevent more serious failures.
• Cleaning: Keeping the fan and radiator clean is crucial to their effectiveness. Removing contaminants such as dust, mud and leaves ensures better airflow.
• Drive inspection: Regularly checking the condition of the V-belt if the fan is driven in this way allows wear to be detected and prevents it from breaking.

Fan repair and replacement:

• Bearings: If the bearings are worn, it is recommended to replace them with new ones to prevent further damage to the fan.
• Blades: Damaged fan blades should be replaced to ensure proper airflow and cooling efficiency.
• V-belt: A worn or damaged V-belt should be replaced with a new one in accordance with the manufacturer's recommendations.
• Electric motor: If the electric motor fails, it may need to be repaired or replaced.
