How can a lawn mower achieve efficient and precise lawn maintenance?

The core technical principles of a lawn mower involve multiple aspects such as the power system, blade design, and working mode. The power system is the energy source of the lawn mower, and the common ones are electric drive and gasoline power. Electric-driven lawn mowers use AC or DC drive motors to drive the mowing rope or plastic blade to rotate at high speed to achieve the function of cutting grass stems; gasoline-powered lawn mowers use gasoline as fuel, generate power through the engine, and drive the blades for mowing operations.

Blade design is a key component of a lawn mower, and its performance directly affects the mowing effect. High-quality blades should be sharp, flat, and wear-resistant. Sharp blades can cut grass stems quickly and cleanly, reduce pulling and damage to the lawn, and make the lawn more neat and beautiful after mowing; flat blades can ensure the uniformity of the mowing height and avoid the unevenness of the lawn surface; wear-resistant blades can extend the service life and reduce the cost of use.

The working modes of lawn mowers are mainly rotary and reciprocating. The rotary lawn mower mows by the rotating motion of the blade, which has the advantages of fast mowing speed and high efficiency, and is suitable for mowing large areas of lawn; the reciprocating lawn mower uses the left and right reciprocating motion of the blade to cut, and its mowing effect is more delicate, with less damage to the lawn, and is often used in places where high lawn quality requirements are required.

To ensure the efficient and accurate operation of the lawn mower, the relevant specifications must be strictly followed during use.

Before each use, the lawn groomer needs to be fully inspected. Check whether the gasoline and lubricating oil are sufficient. If insufficient, they should be filled in time to avoid engine damage caused by insufficient lubricating oil. Check whether the blade is firmly installed, whether the blade is sharp and flat, and whether the tail is intact. Blunt blades not only affect the landscape effect of the lawn, but also easily provide environmental conditions for the infection of diseases; uneven blades cannot mow a flat lawn, and long-term use will also damage the machine; intact tail wings can ensure that the inverted volute forms an updraft sufficient to make the grass blades stand upright, so that the cutting is completed cleanly, quickly and effectively, and there is enough airflow to send the grass clippings to the grass collection bag.

During use, pay attention to observe the reliability of the moving parts and transmission parts of the machine, check whether the gap size is within the normal working range, and adjust it in time if there is a problem; check the firmness of the fasteners, and if there is any looseness, strengthen it in time; listen to the abnormal sound of the machine, diagnose the symptoms and repair it in time. At the same time, it is necessary to operate in strict accordance with the operating procedures to avoid illegal operation that damages the machine and causes safety accidents.

The walking speed of the lawn groomer should be limited to the range where the lawn mower blade can effectively mow and discharge grass and maintain good mowing quality. Too fast walking speed will reduce the working quality of the lawn machinery, and it is also easy to damage the machinery, affect the life of the mowing machinery, and easily cause safety accidents.

Try to avoid mowing the lawn when the lawn humidity is high, such as after irrigation, after rain or dew. Wet grass can easily cause mechanical blockage and slippage, and slippage will accelerate the wear of the machinery. In addition, in the season with high incidence of diseases, the blades and chassis must be disinfected before and after mowing to avoid spreading diseases.

Regular maintenance is the key to ensuring the long-term efficient and precise operation of the lawn groomer.

Strictly fill the fuel and lubricant according to the grade, quality and mixing ratio (two-stroke gasoline engine) required by the engine. For example, the lubricant of the B&S engine should use SAE40 oil. The engine oil should be replaced after 5 hours of initial use and every 50 hours of use after running-in. Gasoline should be 93 or above or unleaded gasoline. Clean the air filter regularly to prevent dust and impurities from entering the engine and affecting the performance and life of the engine.

Sharpen and balance the blade regularly. After the blade is sharpened, check whether it is still in a balanced state. If it is unbalanced, it will cause too much vibration and affect the service life of the lawn mower. If the blade is found to be worn, bent or unbalanced, replace the blade in time to avoid damage to the lawn and increase the risk of mechanical failure caused by continued use.

To extend the life of the grass bag, the weeds in the bag must be removed after each mowing, and the grass bag should be checked frequently. If the stitching of the grass bag is found to be loose or damaged, it should be repaired or replaced with a new one in time to ensure the normal use of the grass bag.

After the mowing season, the mower should be stored in a dry environment. Before storage, it should be sent to a designated maintenance office for inspection and maintenance or maintenance in accordance with the maintenance manual. Disconnect the spark plug connection, turn the mower over to thoroughly clean the inside of the chassis, scrape the remaining weeds with a putty knife or wire wiper, and then rinse with water. When rinsing, it is best to seal the muffler and air filter to prevent water from entering.

Lawn groomers are irreplaceable in lawn maintenance. Through regular mowing, the lawn can be kept neat, beautiful, and attractive, and the lawn function can be fully utilized. Mowing gives the lawn grass a moderate stimulation, inhibits its upward growth, promotes the increase in the density of runners and branches, and makes the lawn more dense and beautiful. At the same time, mowing is also conducive to the entry of sunlight into the lawn base, so that the lawn grows healthily.

Reasonable use of lawn mowers for mowing can determine the appropriate stubble height according to the physiological and morphological characteristics of the lawn grass and the purpose of use, ensuring the normal growth and development of the lawn grass and the function of the lawn grass. Different types of lawn grass have different requirements for stubble heights. For example, the suitable stubble height for cold-weather grass species, such as bentgrass, is 0.6-1.3 cm, while the suitable stubble height for warm-weather grass species, such as common bermudagrass, is 1.3-3.8 cm.

In addition, the precise pruning of lawn groomers can avoid damage to the lawn caused by excessive pruning. Excessive pruning will cause the lawn to lose too many photosynthetic organs above the ground, and too much storage nutrients in the aboveground and underground parts, causing the lawn to turn yellow and weaken. Pruning according to the 1/3 principle of lawn pruning, that is, pruning when the actual height of the lawn grass exceeds 1/3 of the suitable stubble height, can ensure the healthy growth of the lawn.
