Daily Maintenance and Care for Tractors

Daily maintenance and upkeep of tractors are crucial for ensuring efficient operation, extending their service life, and maintaining workplace safety. Key tasks include cleaning the entire machine, checking oil and water levels, servicing filters, verifying the functionality of critical systems, and adhering to a regular maintenance schedule—adjusting these practices specifically based on operational frequency and environmental conditions.
I. Daily Inspection and Cleaning
Perform the following before and after each assignment:
1. Clean the entire unit: Remove dirt, grease, and weeds, paying special attention to clearing the ventilation holes to prevent blockages that could impair heat dissipation.
2. Inspect fasteners and tires: Tighten any loose components, such as walking parts, ensure consistent air pressure in both tires, and verify that the V-belt tension is properly adjusted.
3. Verify the vehicle-mounted tools: Ensure all tools are complete, ready for emergency repairs.
II. Fluid and Filter Maintenance
1. Fluid Inspection and Replacement:

① Daily check the levels of diesel, engine oil, coolant, brake fluid, and hydraulic oil; replenish as needed and inspect for any leaks.
② Change the engine oil and gear oil according to the season (e.g., switch to low-temperature oil in winter), clean the oil strainer, and replace the filter element.
2. Filter Maintenance:

① Clean the air filter every 100 hours: For the dry-type element, gently brush it with a soft-bristle brush, then blow it clean with compressed air and lightly spray with a small amount of oil. For the wet-type element, replace the oil in the oil reservoir.
② Diesel filters should be cleaned or replaced every 200 hours to prevent impurities from entering the fuel system.
III. Verification of Key System Functions
Follow the steps after starting:
1. Engine idling test: Run at idle for 3–5 minutes, then operate at low speed and high speed for 5 minutes each, checking for unusual noises, oil leaks, water leaks, and verifying the functionality of instrument lights.
2. Gait and Steering Test:

① Start slowly, testing gear-shift operation and brake functionality.
② The free play of the mechanical steering wheel should be between 15 and 30 millimeters, while the free steering angle for hydraulic systems must not exceed 30°; any damaged parts must be replaced instead of being repaired by welding.
3. Brake System Inspection: The brake pedal free play should be 10–15 millimeters. If it’s insufficient, top up with the same type of brake fluid and regularly lubricate the pedal shaft. Brake pedal
