How to deal with lawn mower failure? Posted by : admin / Posted on : Apr 14,2022

Now no matter what industry we are in, we are all mechanized. For example, in our agricultural garden, machines can save us time and a lot of labor. Let's look at lawn mowers. For mechanical tools such as mowing lawns and vegetation, the output shaft of the engine is equipped with a blade, and the blade uses the high-speed rotation of the engine to improve the speed a lot, saving the work time of the weeding workers and reducing a lot of human resources. However, the lawn mower will have problems of one kind or another after being used for a long time. Next, let's talk about how to solve the failure.

1. Inability to mow the lawn
Remove the air filter for cleaning, and replace it if it cannot be cleaned. Check the blade for sharpness, if it is dull it needs to be sharpened. In addition, whether the lawn has thick leaves, and if so, the size of the cut should be increased to reduce the load on the engine.

2. If the engine oil is not changed regularly, what kind of failure reactions will the engine have?
With the prolongation of the working time of the engine, the dissolved waste in the oil will gradually increase, the color of the oil will gradually deepen into black, and the lubricating function will gradually decrease. If the oil is not changed regularly, the lubricating function of the oil will gradually decrease, which will lead to excessive oil consumption, premature wear of the engine, loss of power, until the connecting rod breaks and the engine is scrapped. The oil change time should be 50 hours. If the engine works in a high temperature or dusty environment, the oil change time should be about 25 hours, or it can be determined by the color of the oil in the oil chamber.

3. The connecting rod of the gasoline engine is broken or the cylinder block is broken at the same time
Failure performance: The contact surface between the crankshaft and the connecting rod is seized. There are scratches on the contact surface of the connecting rod and the crankshaft.
Cause of failure: There is no or lack of lubricating oil, causing the contact surface (the inner surface of the connecting rod and even the surface of the crankshaft) to be melted and strained at high temperature.
Failure analysis: lubricating oil (gasoline oil) is not added, or the lubricating oil is added but not in place, or the lubricating oil is added in place but the machine is used at an improper angle, causing the oil splash wheel to not contact the oil, so that the crankshaft and the connecting rod are in contact There is no lubricating oil or lack of lubricating oil on the surface, which leads to the first is no lubrication on the contact surface; the other is no cooling. Under normal circumstances, if it is at the rated working speed, the crankshaft and the connecting rod will be seized for a few minutes due to the above reasons, causing the connecting rod to break and the cylinder block to be broken.
