Lawn mower: maintenance before the winter break


The Content Of The Article:

When the time comes for the lawn to go into the winter break, the mower is also mothballed over the winter. But do not put the device in the shed with a half full tank, just leave it uncovered! Due to the long rest and the low temperatures, the device can be damaged by dirt, rust, corrosion and fuel residues. How to make your lawnmower fit for wintering:

basic cleaning

First, clean the mower housing thoroughly. This is particularly important in a steel housing because grass remains accelerate corrosion. But even a lawnmower with a rustproof housing made of aluminum or plastic, it does not hurt if he is well cleaned in the hibernation released.
For safety reasons, remove the spark plug lead from gasoline mowers before cleaning and tilt the mower backward. Alternatively, you can tilt the device to the side, but make sure that the air filter is on the upper side. Otherwise, engine oil or fuel may leak. You should first remove the coarse dirt with a hard brush and then clean the entire unit with a wet cloth. Be sure to wear work gloves because of the risk of injury! You should rinse the grass basket in a rain barrel in order to free it from the coarsest dirt.

First fill a fuel additive into the tank. It keeps the gasoline fresh and flammable during its service life. Then fill the tank with fuel up to the edge and close it

Close the fuel tap and let it run on the lawn until it runs out. Now the carburettor is empty and does not resinify in winter

The air filter should be knocked out or, if present, blown from the clean side with compressed air

Spray the front and back of the knife bar with creep oil and rub the oil with an old rag after a few minutes of exposure. The oil film prevents the blade from rusting during its service life

Engine and drive

When the cleaned lawnmower has dried, moving parts such as the wheel bearing, throttle and launching bar are oiled with a resin-free oil such as "Ballistol". Motor and drive parts, such as the knife shaft, must remain oil-free! But you should impregnate the mower housing from inside and outside with an oil-containing spray.

Empty the tank completely

Finally, fill the fuel tank with some gasoline and close the fuel tap. Now start the device and let it run until the engine runs out due to lack of fuel. In this way, the carburetor empties and can not harden during the winter break. Attention: Residual fuel in the tank may lose its ignitability over the winter. This may lead to startup problems in the spring.

Lawn mower with electric starter or battery

If your lawnmower is equipped with an electric starter, you should also disconnect the battery to prevent it from discharging during the winter break. After and before the start of the mowing season, but also during longer breaks in use, the starter battery should be charged for about 24 hours. This can be done in the installed or removed state. Attention: Before removing the battery, the plug connection to the wiring harness must be disconnected.

Cordless Lawn Mower

Many cordless lawnmowers have a modern lithium-ion battery

Electric mowers

More and more garden tools are now available with a battery. The batteries are the most expensive part of the equipment, so you should pay particular attention to their care. Important: Always store batteries in a frost-free place in the winter, as temperatures below freeze shorten the service life. Optimal temperatures are between 5 and 15 degrees. Depending on the type of battery you should pay attention to the state of charge before prolonged storage: Nickel-cadmium (NiCd) batteries survive many months in the discharged state. When reused, they only reach their full capacity after several charging cycles. Charge lead-acid batteries and nickel metal hydride (NiMH) batteries before storing. If they are not used for more than three months, they should occasionally go to the charging station.The latest generation of devices is usually equipped with lithium-ion batteries. These should be about half full before wintering. Since lithium-ion batteries practically do not discharge themselves, storage for up to two years is possible.

Maintenance at the dealer

Use the time in winter for an inspection appointment with the dealer. There you can, for example, let the knife sharpened. Many professional scissors or knife sharpeners are also familiar with the cut of lawnmower blades. If you want to lend a hand, you should inform yourself in advance about the right touch, because otherwise the damage is faster than the money saved. Have an oil and air filter change in good time before starting the new grass season in a specialist workshop. Then you can easily mow your lawn until next fall.

Tip from a specialist: How to make your lawnmower fit again in the spring

Dominik Wellen is an employee of Stavermann GmbH. The specialist company from Wallenhorst near Osnabrück is one of only 100 companies in Germany that bears the seal of quality "Qualified Motor Vehicle Dealers" (QMF)

Mr. Waves, what maintenance should you do in the spring before putting the gas mower back into service?
A very important thing, which is unfortunately often neglected, is the oil change. Lawn mower engines usually have no oil filter, which removes the fine metal abrasion from the oil. Therefore, such an engine has a significantly higher wear, if you do not change the oil every year. A maintenance date in the spring before the start of the season is the minimum. On the occasion, the knife is also checked and reground or replaced if necessary.
