In order to ensure the usability of tractors, agricultural machinery operators need to master a complete set of maintenance guidelines. Mainly reflected in the process of driving a tractor. What agricultural machinery operators need to do are the following "five don'ts":
Not overloaded. Overload is the main "root cause" that affects the lifespan of tractors. Overloading can cause the engine to overheat, leading to poor lubrication of moving parts and premature wear. The reason for overload: 1. Non matching agricultural machinery, such as "small horses pulling large carts". 2. The workload for loading, plowing width, and plowing depth operations is too high. 3. Trapped in the car. 4. Poor road conditions.
Do not let the temperature be too low. The operating temperature of the engine is between 75 ℃ and 85 ℃. When the tractor is in operation, it should only start at 40 ℃ and work under load at 60 ℃. If necessary, adjust the opening of the insulation curtain (louver) or use methods such as heating water to solve the problem of temperature discomfort.
Do not overheat the engine. Excessive engine temperature can cause poor lubrication, leading to accelerated wear of moving parts. The main reasons for engine overheating are: 1. Insufficient cooling water. 2. The fan belt is too loose. 3. Engine overload. 4. The insulation curtain is not opened. 5. The thermostat valve fails to close the small circulation position of the cooling water. 6. The impeller of the water pump is severely worn. 7. Too much scale. 8. Blockage of heat dissipation core. 9. There are debris blockages between the fins of the radiator. 10. Abnormal friction caused by improper assembly, loss of lubrication, or other reasons.
Don't press the accelerator hard. On the one hand, sudden acceleration can cause additional inertia impact on moving components; On the other hand, sudden acceleration of the accelerator rapidly increases the amount of fuel injected into the cylinder, while the fresh air entering the cylinder is disproportionate to the fuel, resulting in poor combustion, black smoke from the engine, increased combustion carbon deposits, increased machine wear and fuel waste.
The tire pressure should not be too high or too low. Try to avoid sharp edges and potholes as much as possible, slow down when driving on uneven roads, and do not accelerate aggressively; Minimize the number of braking cycles as much as possible, avoid sudden braking, and drive with foresight, supplemented by braking if necessary; Do not place your foot on the brake pedal while driving, and choose the appropriate gear when going downhill. If the gear is too high, the braking frequency should be increased. If the gear is too low, the tractor will slide under downhill thrust, accelerating tire wear; Do not use forced acceleration after getting stuck in the car, otherwise the tires will slip severely and wear more severely.
Strictly following the above points can ensure the good operation of the tractor.
