Lawn mower weeding skills and maintenance

Weeding machine, also known as lawn mower, lawn mower, lawn trimmer, etc., is a mechanical tool used for mowing lawns, vegetation, etc. It is composed of cutter head, engine, walking wheel, walking mechanism, blade, handrail, control Partial composition. The development of agricultural mechanization, improvement of work efficiency, and improvement of agricultural production efficiency are extremely important in a large agricultural country like ours. As an important tool in agricultural production, the lawn mower has the most direct impact on the yield of crops. Its invention is a major advancement in human civilization. In countries where the mechanization of animal husbandry is highly developed, the research of new lawn mowers is developing in the direction of high speed and energy saving.

In the process of traditional agricultural production, weeding is a major task of field management. Common cultivation and management measures for removing weeds include plowing, cultivating, and hand pulling. Although the emergence of herbicides has solved part of the problem of weeding, cultivating is still a necessary measure for field management, because the main purpose of cultivating is not only weeding, but also many functions. For example, it can loosen topsoil, increase soil aeration, increase ground temperature, promote aerobic microbial activity and nutrient efficiency, promote root extension, and adjust soil moisture status.

Traditional cultivating uses manual cultivating methods. Although the accuracy is high, the work efficiency is low. Therefore, the emergence of some small lawn mowers helps farmers reduce the labor burden of cultivating. The following techniques should be paid attention to during the use of lawn mowers. Better improve work efficiency and extend the service life of agricultural machinery.

Before weeding:

Before weeding, the debris in the weeding area should be removed to avoid damage to the cutting head and blade. To start the engine in a cold state, close the damper first, and then open the damper at an appropriate time after starting. If the turf area is too large, the continuous working time of the mower should not exceed 4 hours.

After weeding:

 The lawn mower should be thoroughly cleaned, especially the debris on the radiator must be carefully cleaned. The flying grass clippings adhere to the radiator and affect its heat dissipation function. In severe cases, it will cause the cylinder to pull and damage the engine. Check whether the blade is defective, whether the screws are fastened, and whether the vulnerable parts need to be repaired, so as to extend the service life of the agricultural machinery.

Lawn mower maintenance

1. Maintenance of engine oil

Before each use of the lawn mower, check the oil level to see if it is between the upper and lower marks of the oil dipstick. The oil should be changed after the new machine is used for 5 hours, and the oil should be changed again after 10 hours of use, and then the oil should be changed regularly according to the requirements of the manual. The oil change should be carried out when the engine is in a warm state. Do not add too much oil, otherwise the lawn mower will have black smoke, insufficient power, excessive carbon deposits in the cylinder, small spark plug gaps, and engine overheating. Do not add too little oil, otherwise the lawn mower will experience loud engine gear noise, accelerated wear and damage of piston rings, and even cylinder pulling, which will cause serious engine damage.

2. Maintenance of the air filter

Before and after each use, check whether the air filter is dirty and wash it frequently. If it is too dirty, the engine will be difficult to start, black smoke, and insufficient power. If the filter element is paper, you can remove the filter element and dust off the dust attached to it; if the filter element is spongy, it can be cleaned with gasoline, and then drop some lubricating oil on the filter element to keep the filter element moist. Conducive to the adsorption of dust.

3. Maintenance of radiator

The main function of the radiator is noise reduction and heat dissipation. When the lawn mower is working, the flying grass clippings will adhere to the radiator and affect its heat dissipation function. In severe cases, it will cause the cylinder to be pulled and damage the engine. After the lawn mower, you must carefully clean up the debris on the radiator.
