Technical maintenance of tractor before spring plowing

Under the nourishment of the spring rain, all things come back to life. The earth stretches itself, opens its sleepy eyes, and suddenly realizes that it's time for farmers to loosen its soil. So it sends the myna birds to wake up the tractors that have been hibernating, and it's time for them to go to the fields! As an indispensable mechanical equipment in agricultural production, the technical maintenance of tractors before spring plowing operations is of great importance. The key points of the technical maintenance of tractors before spring plowing operations are as follows:

I. Whole Machine Maintenance

1. Cleaning and Lubrication

Remove the soil, dust, and oil stains from all parts of the tractor. Check whether all exhaust holes are unobstructed and clear them if blocked; check whether the components at all parts are loose, especially re-tighten the walking part and all parts prone to loosening; check whether the steering, clutch, braking and other control devices and lights are reliable, and check whether the tension of the V-belt is appropriate; clean the diesel tank strainer, clean (or replace) the diesel filter, and maintain the air filter.

2. Replacement and Adjustment

Replace the engine oil and gear oil that are suitable for the ambient temperature. At the same time, clean the oil suction strainer and replace the oil filter element. When draining the oil, it should be drained completely while it's hot. It is best to use diesel to clean the oil pan, oil passages and gearbox; check the valve clearance, fuel supply timing, and fuel injection quality, and adjust them if they are not appropriate.

3. Start-up Inspection

Start the engine to make the tractor work, and comprehensively check the working conditions of all parts. If any problems are found, eliminate them in a timely manner, and carry out repairs if necessary.

II. Maintenance of the "Three Filters"

1. Maintenance of the Air Filter

Strengthening the maintenance of the air filter is an important measure to improve the service life of the engine and prevent the decline of power performance and fuel economy. Pay attention to checking whether the sealing performance of the connections of all pipelines of the air filter is good. If the screws, nuts, clamping rings, etc. are loose, tighten them in a timely manner. If any components are damaged or leaking, repair or replace them in a timely manner.

2. Maintenance of the Diesel Filter

Regularly clean the filter. If the filter element is found to be damaged during the cleaning process, replace it in a timely manner. When cleaning, pay attention to preventing impurities from entering the inner cavity of the filter element during the cleaning process, and thus entering the oil passage.

3. Maintenance of the Oil Filter

After the oil filter has been used for a certain period of time, a lot of impurities and dirt will adhere to the filter element. Therefore, it should be replaced regularly according to the requirements of the instruction manual. For a vehicle in normal operation, the oil filter should be replaced every 6 months or after working for 200-300 hours. For the oil filter of a large vehicle, the filter element should be cleaned according to the above time and mileage. Under harsh conditions, such as frequently driving in a dusty environment, it should be replaced every 150 working hours.

III. Whole Machine Inspection and Maintenance

1. Pre-departure Inspection

Before spring plowing operations, a detailed pre-departure inspection is required first, including checking whether the diesel, engine oil, cooling water, brake fluid and hydraulic oil are filled up and whether there is any leakage; checking whether the tire pressure is sufficient and whether the tire pressures on both sides are the same; checking whether the engine works normally at different speeds after starting; checking whether the instruments, lights, horn, windshield wiper, indicator lights, clutch, brake, steering wheel, etc. are normal; checking whether there is any looseness in the connecting parts and fasteners; whether the battery terminals are clean, whether the wiring is tight, and whether the vent holes are unobstructed; checking whether the on-board tools and accessories are complete.

2. Inspection During the Journey

After driving for about 2 hours, the tractor should be inspected. The main items include: observing the working status of all instruments, and all components of the engine and chassis; stopping the vehicle to check whether the temperatures of the hub, brake drum, gearbox and rear axle are normal; checking the status and tightness of the drive shaft, tires, leaf springs, steering device and braking device; checking the condition of the loaded goods.

IV. Special Precautions

1. Engine Cleaning

Engine cleaning is a key step to ensure the normal operation of the tractor. The engine of the tractor is the core component of the operation. If the engine is invaded by dirt and dust, it will lead to problems such as incomplete combustion and poor cooling, affecting the performance and efficiency of the tractor.

2. Oil Circuit Cleaning

Oil circuit cleaning is an important step to ensure the normal lubrication of all components of the tractor. The oil circuit is the source of lubrication and cooling for all components of the tractor. If there are impurities and dirt in the oil circuit, it will affect the lubrication effect and even lead to wear and damage of the components.

3. Hydraulic System Cleaning

Hydraulic system cleaning is an essential step before the tractor operation. The hydraulic system is an important part of the tractor, which is responsible for controlling the operation of various working components. If the hydraulic system is affected by pollution and impurities, it will cause the hydraulic oil pump to work abnormally, and thus affect the operation effect.

Through the above detailed inspection and maintenance steps, it can be ensured that the tractor is in the best condition before spring plowing operations, thereby improving the operation efficiency and safety.
