How to choose a lawn mower?

Answer: The choice of lawn mower should be based on the size of the lawn, terrain, obstacles and how to deal with the cut grass. If the lawn area exceeds 2000m2 or 3 acres, please choose the self-propelled model to improve efficiency. The terrain is undulating or slightly sloped, and the self-propelled model can be selected. When there are flower beds, shrubs or hedges in the lawn, please choose the model with a universal guide wheel on the front wheel. The grass collection or shredded grass mulch in the three-in-one cutter head is particularly suitable for the treatment of grass:

——Side row is suitable for large area and evenly mowing, the labor intensity is lower than that of grass gathering.

——Grass collection function is used for fine pruning and places where high lawn quality is required.

Problems that should be paid attention to in the use of lawn mower

1. A new lawn mower was purchased by a certain unit, and it was running normally the first time it started, but it suddenly stopped after 5 minutes, and it stopped every time it started. During maintenance, it was found that the machine did not malfunction because the fuel tank sealing cap was not removed, causing negative pressure in the fuel tank, causing poor fuel supply and shutdown. The machine runs normally after removing the sealing cover. This requires sellers to provide on-sale services to avoid the occurrence of the above-mentioned problems.

2. A new lawn mower was purchased by a unit, and it suddenly stopped and the engine could not start after 30 minutes after starting. After maintenance, the mechanical indicators were all normal. Finally, it was found that the fuel label was incorrect. After changing the oil, everything was normal. When purchasing fuel, the user should pay attention to the fuel label and use the correct fuel.

3. A company bought a lawn mower. After using it for a day, I called and said that there was a problem with the lawn mower and it could not be started. It turned out that the user was changed the next day and no gasoline was added. Everything is normal after refueling. The user should train the machine operators to ensure the correct use of the machine.

4. I received a phone call from a user saying that the lawn mower I just purchased was not powerful enough to cut the grass. It turned out that it was not the lawn mower problem, because the lawn grass they cut was more than half a meter high. Therefore, we must abide by the one-third lawn mowing principle, otherwise it will have a great impact on the service life of lawn mowers and lawn life, and also affect the beauty of the lawn.

5. A new lawn mower was purchased by a company, and after 3 days of use, black smoke and insufficient power appeared. The reason is that there is too much oil, the oil level is too high, and the oil sprays from the breathing hole to soak the filter element, causing insufficient air intake. The filter element should be replaced, and the amount of oil added should be controlled, then the lawn mower runs normally. Sales units are required to do a good job in-sale explanations, and users must carefully read the machine instructions, use them correctly and maintain them correctly to make the machine run normally.

6. A new lawn mower was purchased by a certain unit, and the machine could not be started after less than a month of use. All internal parts of the machine are severely worn, and the crankshaft, piston, cylinder, etc. have exceeded the scrap standard, and there is no maintenance value. It was discovered that the engine oil used was fake and inferior, and the engine oil contained a lot of metal filings and sand. It is required to use the oil with the designated label in the machine manual, and pay more attention to the purchase channel, so as to avoid unnecessary economic losses.

7. A certain unit purchased several lawn mowers, and when one of them was used, it only turned around once when it started, and the machine was stuck and could not be turned. Because when the machine was purchased and tested, the machine oil was added. When the machine was packed and pulled back into the warehouse, the lawn mower was turned upside down and the oil flowed into the cylinder. After the oil was discharged from the cylinder, the lawn mower would be used normally.

8. A unit purchased three lawn mowers from a dealer, and when running in, the three lawn mowers shut down one after another. After inspection, all three machines were caused by cylinder pulling caused by no oil. The distribution unit is obliged to provide operation and maintenance training to the users in order to use and maintain the lawn mower correctly.

Nine, the one-third principle of lawn mowing

A company bought a new lawn mower, and soon called, reflecting that the lawn mower was not powered enough and it was difficult to cut the lawn. When I came to the site, I learned that the lawn grass grew too high and it exceeded the cutter head of the lawn mower. Therefore, the mowing of the lawn should control the height of the lawn grass within a certain range according to the specific purpose of the lawn, and the principle of one-third should be followed during each mowing: that is, the height of the mowed lawn grass accounts for one-third of the height of the entire lawn . This is not only conducive to the regrowth of lawn grass, but also conducive to the normal function of the lawn trimmer.
