How to choose the best cordless grass trimmer

It can take some time to master a handheld cordless trimmer. But you will be happy to know this is one of the tasks that can be relaxing when you use the right tool. This is why the strimmers seen above enjoy so much popularity as they have been reviewed positively thousands of times. When you buy your first trimmer that comes with a cordless design, this is what you need to consider.

Cutting swathe

The cutting swathe or the cutting diameter of the trimmer is important. It generally varies from a small 24cm size to a large 34cm diameter. You can even look at the products that are a bit more suitable for your garden. This means considering things such as overall capabilities to cover your lawn with a certain grass swathe on a single battery charge.

If you have a large lawn of over 300 square feet, you can easily choose strimmers with a cutting swathe of more than 30cm. This will allow you the ultimate practicality without your batteries running out before you finish trimming the grass.

Battery life

Battery capacity is important. But the cheaper grass trimmers don’t come with advanced battery technologies such as fast charging. These are the most important aspects to consider when it comes to the overall usability of a trimmer. You should know that your lawn should be trimmed on a single battery charge with these systems as you won’t have time to recharge the batteries and go back to finish the job on the same day.


The last thing you want from a handheld tool is for it to be heavy. This is why you need to choose the strimmers which are of high-quality but which are also very lightweight according to the manufacturer-provided information. For some, this can be easier said than done. But we’ve selected some of the lightest strimmers above so that you don’t have to suffer from stiff hands or back pain when trimming grass.


How comfortable is the strimmer in your hand? This is answered with ergonomics. An ergonomic handle or multiple ergonomic handles on your trimmer should be designed in an angle that doesn’t cause any hand pain due to difficult grip positions. You should also look at the trimmers that come with anti-slip handles so that you can continue working even in the summer when your hands tend to sweat a lot.


Some of the best cordless grass trimmers are made from durable materials. Brushless motors, durable nylon cord, and metal shafts make these very durable. Most of them are also efficient. But the finest results are usually obtained by the trimmers that come with the highest rotations per minute for clean cuts. With the right scarifier, these cordless trimmers can make your lawn look pristine.

But their biggest advantage remains the high versatility given by the rechargeable batteries. These allow you to run around the law with the trimmer without needing to add petrol. Gas or petrol models are still popular in some categories with powerful speed delivery, but it’s just easier to charge than to always stop at the gas station to fuel your cordless strimmer.

Is straight or curved shaft trimmer better?

A straight shaft trimmer is best for most garden jobs and most lawns. It handles all outdoor trimming perfectly. But there’s the curved shaft which is superior in areas that are hard to reach.

How do I choose a grass trimmer?

You need to look at cutting width, weight, and rotations per minute to determine the right type of grass trimmer to use at home. This gets you products that impress in terms of reliability and which don’t even need to be too expensive.

Why do straight shaft trimmers turn counterclockwise?

The grass is ejected to your left side as you move the trimmer to the right side. This is why the straight shaft trimmer turns counterclockwise.

What's better 2 cycles or 4 cycle trimmer?

4 cycle trimmers brands are known for higher speed or more rotations per minute. 2 cycle trimmers are known for higher torque and they can be a bit better for thick grass and thistle.
