Mini Buyers Guide

Key things to consider before buying a cordless lawn mower

If you want the convenience of an electric lawn mower without the hassle of extension cords, a cordless model is a great consideration. Improvements in battery technology makes them last much longer as well as benefit from reduced overall weight.

When it comes to buying one, you have to think of the size of your garden. The point is, some lawn mowers are good for smaller gardens while others only make sense if bought for larger lawns. Leading from this, look at the battery voltage and ampere per hour. Ideally, 18V and 20V batteries will offer enough power and runtime for smaller gardens of around 250m², while 36V and 40 batteries are adequate for larger lawns, about 450m² and above.

Many models feature variable cutting heights and you’ll want to choose a decent range for your lawn. Closely related to that is cutting width, which typically ranges from 32cm to 50cm. A machine will a lower value will take longer to mow a certain area, while a wider width will get the job done much quicker.

You may also want to consider some extra features such as folding handles, grass combs, weight of the machine, and battery charging time.

It arrives partly assembled and that means you’ll need to get some other parts together before first time use. It’s a five-minute job, however, with the instruction manual being very easy to follow. A great feature of this mower is the 40cm cutting width. Its quite large that every pass will be really wide, reducing time, effort and power.

Starting the machine is really easy and safe. Simply engage a lock-out button and apply the Operator Presence Control (OPC) lever.

Buyers Guide

Thinking of buying a cordless lawn mower but not sure what features and specs to consider? With plenty of options to choose from, deciding the best battery powered mower for your garden needs some research. Go through the buyer’s guide below for some tips on how to select a cordless mower.

Benefits of a cordless model 

  • Convenient operation – with a cordless mower, there is no worrying about where the cord is but rather cut your lawn without one entirely. A cordless mower offers total freedom and you can mow in whatever manner you want.
  • Easy to operate – compared to worrying about oil or pulling a cord, the only thing you need to do to start is press a button and squeeze a handle.
  • Lightweight construction – many cordless models have a 10 to 20kg weight difference from petrol models for example. Although it may not sound like much, the implication will start to show after a few minute of pushing the mower.
  • Easy storage – with no petrol to think about nor cords to wrap around the handle twenty times, many of the cordless models only require you to fold down the handle and store in the shed.
  • Quiet operation – battery-operated lawn mowers are very quiet and that means you can mow early in the morning or late evening without disturbing your neighbours.
  • Eco-friendly – without emitting harmful gases into the air, cordless mowers are some of the safest machines to use in the current environment conscious society.

That said, let’s look at the factors to consider when buying a cordless lawn mower.

Factors to consider when choosing a cordless lawn mower

Lawn size and condition

Cordless lawn mowers are generally suited to small and medium sized lawns. That’s because they run on batteries, which will drain at some point. If you have a large garden, about over 400m², you will need to be careful of your selection otherwise you might have to take breaks half-way through to recharge the battery. Leading from this, charging time is another thing you’ll need to think about. If you have to take a break, look for a model that charges quickly.

It’s also important to note the condition of your lawn. For instance, even lawns require less power from a lawn mower, meaning the battery will last longer. Similarly, short grass is easier to cut than dense growth, and won’t drain the battery as fast. If you have a large lawn, uneven lawn and the grass is constantly thick, long or wet, keep in mind you’ll need a mower with a powerful battery. Alternatively, get a secondary battery.

Cutting width and adjustable height

Wider cutting widths are suitable for larger lawns as they require fewer passes to complete a given area. This also means the battery is less likely to die before you finish mowing. For medium to large sized gardens, you will want to go with a mower with a cutting width of about 39 – 42cm.

Small and medium sized lawns should be okay with a cutting width of around 32 – 39cm. Just keep in mind that the smaller the cutting width, the more cutting you will need to do. This could imply that the battery dies before you complete the job.

When it comes to cutting heights, you can expect a decent range to use. Many will offer adjustable cutting heights starting from 20 to 80mm. The lower settings are good for keeping the lawn well-manicured, while the higher settings are perfect for cutting lots of length. In short, it’s good to have several options, so consider a mower that offers a nice range.

The right battery

There is more to the battery than just run time. Battery power and ampere per hour will have an impact on the overall mowing power and speed. A weak battery will struggle in difficult conditions such as slopes or thick grass.

Battery voltages come in the form of 18V, 20V, 36, and 40V. The lower voltages provide a decent amount of power and runtime, though only sufficient for smaller gardens. 36V and 40V options are ideal for the standard UK lawn.

Ampere hour varies between models too. A 2Ah battery is the most common as seen from the models above. It offers a good runtime and fast recharge, while many cordless mowers come with two batteries so you can switch between. Larger and more powerful mowers may come with a 4Ah battery, which offers double the capacity of a 2Ah battery.

Go for a 40V 4Ah battery if your lawn is on the larger size and probably if it has uneven terrain and dense overgrowth. Smaller lawns with flat terrain will use an 18V or 20V 2Ah battery without any issue.

Our Final Conclusion

Cordless lawnmowers have come a long way and they aren’t going away any time soon. They are convenient, easy to use, and virtually maintaince-free, giving all the good reasons to own one. We hope this guide has made it easy for you to find the best lawn mower for your garden.
