Summer Is Coming Soon, Are Your Tractors Ready？

The hot summer season is the busiest season for agricultural production, and it is also the busiest time for agricultural machinery to engage in harvesting, machine tillage, irrigation, and threshing operations. Therefore, in summer, it is necessary to strengthen the inspection and maintenance of tractors, use them correctly, in order to reduce the failure rate and improve work efficiency.

(1) Do a good job of maintenance before summer. Before entering summer, it is necessary to perform a high-level maintenance on the tractor, thoroughly clean, adjust, and repair all parts of the tractor according to requirements, replace the oil and gear oil used in summer, and especially conduct a comprehensive inspection and maintenance of the engine.

(2) Carefully remove scale from the engine cooling system. Scale is a poor conductor of heat, and its thermal conductivity is only 1/8 of that of steel parts. When the thickness of scale exceeds 1mm, it will significantly reduce the engine's heat dissipation ability. When cleaning, ammonium nitrate can be prepared into a 0.3% -0.4% aqueous solution and injected into the cooling system to react chemically with the carbonate in the scale, generating a substance soluble in water and exchanging it with water.

(3) Regularly pay attention to the temperature of the engine and the amount of water in the water tank. In summer, the cooling water evaporates quickly and the water tank is prone to boiling. Once it is found that the cooling water is insufficient and the boiler is turned on, the operation should be stopped and the engine should be idling. After the water temperature drops, cooling water should be added to prevent sudden addition of cooling water at high temperatures, which may cause the cylinder block and cylinder head to explode.

(4) The tightness of the fan drive belt should be appropriate. Before starting the engine, it should be checked and adjusted. Generally, it is advisable to press 15-20mm with your thumb in the middle of the drive belt.

(5) When working in the field, the plowing depth and working width of the unit should be reasonably controlled and adjusted to avoid overloading the unit and overheating the engine. During road transportation, it is also not allowed to overload for a long time, and the load in summer should generally be controlled at around 85%.

(6) The tire pressure should be slightly lower than normal. Due to the thermal expansion of the gas inside the tire at high temperatures, if the tire pressure is too high, it is easy for the tire to burst during driving. If the tire temperature is found to be too high, the vehicle should be parked in a cool and shaded area to cool down. Do not pour cold water to cool down, in order to avoid tire cracking.

(7) The water inside the battery evaporates quickly at high temperatures, so it should be checked once a week to keep the liquid level 10-15 mm above the electrode plate. If the liquid level drops, distilled water should be replenished in a timely manner; If the liquid level drops due to electrolyte overflow, the electrolyte should be replenished.

(8) Regularly clean the mud and dirt on all parts of the body, remove straw and other debris from the gaps in the radiator, to avoid obstructing the body's heat dissipation.

(9) When the unit is shut down, it should be parked in a cool and ventilated place to avoid the aging of rubber components such as tires and shorten their service life.

This year's Three Summers is coming soon, and the army of tractors is about to enter the "Three Summers War". Only by inspecting and repairing tractors and putting them into operation in normal condition can we provide equipment foundation for winning the "Three Summers War" and achieving a bountiful summer harvest.
