The tractor provides the driving force for many agricultural tools, that's why its working time is longer than other machines throughout the year.
Oil contamination reduces engine life more than any other factor. As the oil passes through the surfaces of the moving parts, soot and abrasive materials are separated from these surfaces and carried with the oil.
To lubricate the moving parts inside the engine, oil is poured into it. This oil has a certain period of use, which must be changed according to the operating time of the tractor specified in the tractor manual.
First, you should prepare the appropriate percentage of antifreeze solution according to the lowest possible temperature of the area at the coldest time of the day and night and the water capacity of the cooling system. This should be done according to the antifreeze usage instructions on the antifreeze can.
With the penetration of air into the fuel supply circuit, the engine works irregularly or shuts down, in this case, the fuel supply system must be bled.
From the production process to the transfer of diesel fuel to the tractor, there is a possibility of impurity entering it. Due to the high sensitivity of injector pump parts and injectors, used diesel must be completely free of suspended particles and water.
The dry strainer must be serviced according to the manual. Some tractors, such as the MF399, have an air filter change warning light, which should be replaced when it lights up.
In pre-strainers, there is a line or index on the dust collector. Some drivers mistakenly fill the sump with oil up to the MAX line. This is wrong and aerosols are not separated from the air. Clean the pre-filter bowl before the dust inside the pre-filter bowl exceeds the limit (above the Max mark or the line on the bowl).
