So in this article, I’ll focus on some of the things you should avoid doing to your mower so that it won’t give you any troubles whenever you use it. Moreover, I’ll also highlight some tips on proper care and maintain the mower so that it survives for many years without replacing it.

6 Lawnmower Safety Tips

Even though a lawnmower is a powerful piece of machinery that is sturdy and durable, you still have to treat it well. It’s pivotal to save you from spending large amounts of money for repairs or buying a new mower. Here are things you shouldn’t do to your lawnmower.

Do not neglect the air filter

The air filter collects and prevents dirt from getting into the engine through the carburetor. If the air filters get neglected, the dust will accumulate. In turn, that will prevent oxygen from getting into the engine and causing the mower to overheat. Depending on the model of a lawnmower, you must replace or clean the air filters.

Do not mow anything that is not grass.

Lawnmowers’ purpose is to mow grass only. There are called ‘lawnmowers’ for that particular reason. Only use it to mow grass or weeds growing with the lawn. Do not use it to mow over twigs, fallen tree branches or tree stumps because it will immensely damage the mowers deck, spindles, blades, and crankshaft.

Don’t use it for any non-cutting job.

You shouldn’t use the mower to re-spool rope or barbed wire. Not only will that damage the mower undercarriage and blades, but it will affect the mowers’ overall performance.

Don’t use it to mow wet grass.

Under no circumstance should you use your mower to mow wet grass? Wet grass is slick; therefore, moist clipping will stick to the mower and cause it to clog.


Never leave old fuel in the lawnmower tank.

Don’t leave fuel that has ethanol in the tank if you are not going to use the mower for 2-weeks. Fuel internally destroys the carburetor and other elements.

It is always advisable that if you’re not going to use the mower for 90days or more, you should either use up all the fuel or drain it. Even when you use it or remove it, small amounts will remain. You should add a fuel stabilizer in the tank so that the mower won’t refuse to start the next time you use it.

Never leave the battery connected.

Always disconnect the battery if you are not using the mower regularly. Even when the mower is turned off, the mower can still drain off power from the battery. To preserve the overall battery life, you must disconnect the battery.

Cutting wet grass with an electric mower

Cutting wet grass with an electric mower is very hazardous, mainly using one that has an extension cord. You can get electrocuted if the wire gets exposed to moisture. Moreover, wet grass is generally slippery, while mowing one might slip and hurt them. Here are the reasons why you shouldn’t cut wet grass with an electric lawnmower;

  • The inlets of the lawnmowers collection box will get jammed and clogged by damp grass clippings.
  • Wet grass will cause grass clumps to build-up in the electric mower blocking the airflow and the blade. It will also subsequently cause blockage and force the mower motor to overwork until it breaks down.
  • Tall wet grass exerts strain, which will cause the electric mower motor to overheat and smoke.
  • If you didn’t remove wet grass, moisture would collect in the mower causing internal parts of the mower to rust. And the rust will cause extensive damage and causing the mower to break down eventually.
