5 signs that tell you your cordless lawn mower needs repair!

Cordless lawn mowers are efficient, convenient tools that make lawn care easy and fast. However, just like any other tool, they require maintenance and inspections to ensure smooth operation in the future. Leaving minor issues unaddressed can lead to severe damage and higher costs. In this article, I will discuss 5 signs that your cordless lawn mower might need repairs, along with tips to prevent these problems and extend the lifespan of your cordless lawn mower. 

If you notice that your cordless lawn mower's battery runs out faster than usual, even after being fully charged, this could be a sign of battery degradation. This issue can stem from heavy use, improper charging methods such as leaving the battery charging overnight, or operating in environments that are too hot, which accelerates battery wear.

The preventive method is to follow the manual's recommendations, such as charging the battery at a suitable temperature and avoiding continuous operation without breaks. If this issue occurs frequently, you will certainly need to replace the battery with a new one or have a specialist inspect it for a detailed evaluation.

When you try to turn on the cordless lawn mower and it is completely unresponsive and silent, it might have given up the ghost! Haha. This can happen due to electrical system issues, such as a loose battery, a faulty power switch, or problems with the internal circuitry. These issues can arise from operating in damp or dusty environments, which can affect electrical circuit connections.

Initial troubleshooting involves checking the battery connection, inspecting the condition of the switch to see if it is stuck or damaged, and cleaning around the terminals with a clean, dry cloth. If the problem persists, it may be necessary to take the machine to a specialist to inspect the electrical circuit and repair the damaged parts.

If the blades or trimmer line of your cordless lawn mower can no longer cut grass as smoothly as before, or take longer to cut the same area, this could be a sign that the blade is dull or damaged. Using a cordless lawn mower in areas with hard objects like rocks or tree roots can cause the blade to chip or lose its edge. Periodically inspecting the blade and properly sharpening it are essential for maintaining cutting efficiency. In addition, replacing the blade when it is too worn to be sharpened will help restore cutting performance and reduce the workload on the motor in the long run. 

Loud noises or vibrations that have never occurred before may indicate internal issues, such as loose components, motor wear, or problems within the operating mechanism. These issues can result from heavy use without proper maintenance, such as allowing grass clippings or dirt to accumulate inside the tool for long periods.

A preliminary solution is to regularly clean various parts of the cordless lawn mower and inspect screws or components for any loosening. If you encounter this problem, do not force continued use, as it may cause further damage to the parts. You should stop the machine and have it inspected or repaired immediately to avoid more severe damage.

Lastly, this is quite serious: if you smell burning from your cordless lawn mower, it is a warning sign of an electrical issue or an overloaded motor. Rapidly rising temperatures are also a symptom you should not ignore. Turn off the machine immediately and check if there are grass clippings or foreign objects stuck inside—such as dirt, grass, or hard debris that might obstruct the blade or motor rotation. In addition, working continuously for extended periods without breaks can also cause the machine to overheat.

A preventive method is to operate the tool in short bursts, alternating with breaks to allow the machine to dissipate heat. If the problem persists or is accompanied by other symptoms such as abnormal noises or severe vibration, take the tool to a professional for inspection and repair to prevent more serious damage.

Proper use of your cordless lawn mower and regular inspections will help extend its service life. However, if you notice any of the 5 signs mentioned above, do not force continued use, as this can worsen the problem. Having the tool serviced by a professional is the best choice for maintaining the performance of your cordless lawn mower.
