Why is it difficult to start a tractor? What are the solutions?

Tractor is one of the irreplaceable special tools in agriculture. With the progress of science and technology, there are more and more kinds of tractors, and they are used more and more frequently in agricultural production. But in the case of driving a tractor, you will find why it is difficult to start the tractor. What are the solutions?

Cylinder head nut is not tightened or cylinder gasket is damaged. If there is steam leakage sound on the sealing surface between the cylinder head and the human body when rotating the transmission shaft, it may be that the cylinder head nut is not tightened or the cylinder gasket is damaged. If it is the former, it should be tightened as required. In the latter case, when the cylinder gasket is slightly damaged, asbestos thread can be used to repair the damaged part, and the gasket can be replaced in serious cases. There are two reasons for air leakage in the intake and exhaust valves: first, the valve is too small to close the cylinder tightly, and the valve must be re-planned. On the other hand, there may be rust, carbon deposit and other dirt on the sealing spherical surface of the cylinder, which also makes the cylinder not closed tightly. When checking, you can rotate the transmission shaft. If you hear the sound of "squeaking" in the air filter and exhaust pipe, it means that there is steam leakage in the intake and exhaust valves. The cylinder must be grounded.

The engine piston is damaged too much. When the transmission shaft rotates, the internal structure of the human body (such as the low oil shell) has air leakage sound, because most of it exists on the engine piston. Some pure automobile engine oil can be added to the cylinder. If the tightening force is obviously enhanced after adding, the engine piston should be replaced at this time. When the engine piston moves to a straight line (alias professional counterpart), the engine piston is stuck in the ring groove body due to carbon deposition, and the clamping cylinder cannot be ejected. When the transmission shaft rotates, there is a steam leakage sound in the crankcase ventilation system. The engine piston should be removed to remove carbon deposits. If the ring mouth moves to a straight line, the positions of the joints should be evenly distributed, but the sub-direction of the cylinder liner must be bypassed.

The fixing bolt of the fuel injection pump is loose, and the fuel injection pump on the cylinder leaks steam, so it should be tightened first. In addition, the piston pin or shaft sleeve is locked, so that the transmission shaft cannot rotate; It is difficult to start the tractor because the piston rod is installed backwards or the air filter is blocked. The next time a large tractor runs, it will be more difficult to start, so we can check it from these aspects. Naturally, everyone also needs to make more efforts in the daily maintenance of tractors.
