Autumn is a critical period for lawn maintenance, and the reasonable use and maintenance of lawn mowers can not only ensure the beauty of the lawn, but also extend the service life of the equipment. The correct use of the autumn lawn mower, maintenance points and precautions help users ensure the normal operation of the equipment in the fall and the following spring.
1. Key points for using lawn mowers in autumn
1 Mowing height adjustment
The growth rate of the lawn slows down in autumn, and the mowing height should be appropriately increased, generally recommended to be kept at 5-7 cm. Higher blades of grass enhance the cold resistance of the lawn and reduce the risk of frost damage in winter. The specific adjustment methods are as follows:
Single Wheel Mower: Adjust the mowing height by adjusting the wheel height, ensuring the height of the four wheels is the same.
Self-propelled lawn mowers: Some models are equipped with height adjustment levers that can adjust all wheel heights at once.
Precautions: Avoid mowing more than 1/3 of the grass height at a time to prevent the lawn from being damaged by over-mowing.
2 Mowing time selection
Autumn mowing should choose sunny and dry weather, and avoid doing it in the morning when the dew is not dry or after rain, so as not to prevent grass clippings from sticking to the blades or clogging the machine. The best mowing time is from 10 am to 4 pm, when the lawn is dry and safer to operate.
3 Grass clippings treatment method
Autumn grass clippings are rich in nutrients and can be treated in the following ways:
Direct return to the field: Spread grass clippings evenly on the lawn, which can be used as organic fertilizer after natural decomposition.
Collection and cleaning: If there is too much grass clippings or lawn diseases, they should be collected and treated in a timely manner to avoid the spread of diseases.
Precautions: When using grass collection bags, they should be emptied regularly to prevent excessive weight from affecting the performance of the machine.
2. Autumn lawn mower maintenance steps
1 Cleaning and inspection
After each use and before the end of the season, the mower needs to be thoroughly cleaned:
External cleaning: wipe the fuselage with a damp cloth to remove dirt and grass clippings, and pay special attention to the cleaning of heat dissipation holes and vents.
Blade inspection: Turn off the engine and unplug the spark plug wires, check for wear or deformation of the blades, and sand or replace them if necessary.
Air filter: Take out the filter, blow off the dust with compressed air, and replace the filter element with a new one if the oil is serious.
2 Fuel system maintenance
When the temperature drops in autumn, the fuel is prone to deterioration, so you need to pay attention to the following points:
Fuel selection: Use gasoline that meets the equipment requirements and avoid gasoline containing ethanol to prevent corrosion of the fuel system.
Fuel storage: Before long-term storage, the remaining fuel in the tank should be emptied, or fuel stabilizer should be added to prevent fuel oxidation.
Carburetor inspection: If the machine has been idle for a long time, it is recommended to remove the carburetor and clean the internal grease to ensure smooth use next time.
3 Lubrication and fastening
Regular lubrication and tightening of components reduce wear and extend lifespan:
Lubrication points: Check the mower's bearings, gears, and movable joints, and add an appropriate amount of lubricating oil (such as lithium-based grease).
Fastener inspection: Check the blade fixing bolts, wheel screws, etc., to ensure that there is no looseness, and use a wrench to tighten if necessary.
Battery maintenance (electric lawn mower): If it is an electric lawn mower, you need to check the battery level, fully charge it before long-term storage, and replenish it every 1-2 months.
4 Blade Maintenance
The blade is the core component of the lawn mower, and autumn maintenance should be paid attention to:
Sharpen the blade: Use a special whetstone or grinder to sharpen the blade to keep it sharp and ensure the cutting effect.
Balance check: After grinding, the blade balance needs to be checked, the blade can be placed on the tip of the knife, if it is unbalanced, it needs to be adjusted or replaced.
Anti-rust treatment: After cleaning the blade, apply a small amount of oil or rust inhibitor to prevent rust caused by the humid environment in autumn.
3. Long-term storage preparation
If the mower needs to be stored for a long time in winter, the following preparations are required:
Clean the whole machine: Thoroughly clean the grass clippings and dirt on the fuselage, chassis and blades.
Drain the fuel: Turn off the fuel switch and start the engine until the fuel is depleted, or use the fuel extractor to drain the tank.
Oil change: For four-stroke engines, it is recommended to change the oil to a new one to prevent impurities from the old oil from corroding the engine.
Storage environment: Place the mower in a dry, ventilated room away from direct sunlight and humid environments, and cover with a dust cloth
