Best Cordless Lawn Mowers in 2021

We have been leading the industry in providing the best garden machinery to the UK since 1908, so we know a lot about the best cordless lawn mowers. While petrol mowers use fuel as their power source, cordless mowers give you an electric battery that is rechargeable and perfectly suitable for small garden spaces – and there are models designed for larger areas too.

Cordless mowers will have sufficient run time to cut small and medium-sized lawns with no trouble. The benefits of choosing a cordless lawn mower include the following:

  • Suitable for most budgets: Cordless electric lawn mowers are cheaper than their petrol-powered counterparts. If you have a small lawn then there is no need to invest in more expensive petrol mowers as cordless mowers provide sufficient cutting widths and cutting heights to manage the grass.
  • Easy to manoeuvre: You can benefit from the easy manoeuvrability that a cordless lawn mower delivers, thanks to them using fewer parts and lighter-weight materials. This makes cordless designs great for people who are uncomfortable using big mowers designed for large garden spaces.
  • Rechargeable batteries: Fuel is expensive, but with a lithium-ion battery you get a fast charge time of up to 30 minutes. Using a spare battery and charger means you can quickly swap out a drained battery and continue mowing, handy for large gardens. Modern models have great battery life.

Here we will explore the best cordless mowers available in 2021, which includes cheaper models for small gardens and more expensive types for large gardens or tackling longer grass. It can be difficult to choose a mower but we will help by providing a rundown of the best models and their features.

The Best Cordless Lawn Mowers for 2021

Before we get into the details of specific models, we can assist you by offering some information on what will make the most appropriate choice. Remember that compact designs have a lower power battery and will be unsuitable for large gardens or longer grass – so this is a primary consideration when choosing.

Another important point is to consider the frequency and intensity of your planned usage. Some cordless mowers have small batteries and a quick charge time, whereas others have a larger battery that will mean waiting a few hours to charge it fully. If you use the mower a lot a big battery, or spare, may be necessary.

With these two important points in mind, we can look at some of the best cordless lawn mowers for various types of use.

1. The All-Rounder: STIHL RMA 448 VC 18″ Cordless Variable Speed Lawnmower

  • Resistant design: Garden machinery can be subjected to the elements of moisture, heat, sun and wear and tear – but this mower has a lightweight polymer design that resists heat and ultraviolet radiation. The sturdy STIHL manufacturing process protects the battery and inner mechanisms.

2. The Power Player: Honda izy-ON HRG 416 XB 16″ Cordless Push Mower

Some of the core components of the STIHL RMA 235 13″ Cordless Lawnmower that make it one of the best small designs include the following:

  • Lightweight design: While electric mowers are generally a lot lighter than other types, this one comes in at a feather-light 14 kg. It is very easy to push and the weight makes it super manoeuvrable across corners of lawns and when mowing the lawn on an incline.
  • Large grass box size: This model is still amazingly capable of high performance in terms of grass collection, it has a massive 30 l grass box that can handle shorter grass on large lawns or longer grass on small lawns very well. Both the small and large models have a folding grass box design.
  • Eco-performance: You will get an economical battery with this STIHL RMA series of cordless mowers, which is even more important for the compact models that might not experience heavy or intensive use. Turn on eco mode to automatically adapt the motor to the level of power you are using.

This is a cheaper model of the STIHL cordless mower we listed above. However, good things come in small packages and this is a great electric mower with stellar battery performance and heavy-duty functionality. If you are looking for high-performance at a lower budget this is the model for you.

What to Look for When Choosing a Cordless Lawn Mower

The above lawn mowers are some of the best available, but you may have a different model in mind or simply want to browse a selection in a store before buying. If this is the case, then you can easily find a cordless lawn mower that is reliable and effective if you look for the following criteria.

  • Battery life and quality: There is nothing more frustrating than being in the middle of mowing a lawn only to have it conk out, leaving you with an incomplete job. Look for the battery life information but also note models that feature advanced battery technology, as this is a sign of reliability.
  • Build materials: If you see a model that uses sturdy metal, polymers and other hardwearing materials such as fibreglass this is a sign the mower will withstand the use it needs to – as well as being lightweight and easily manoeuvrable. Avoid flimsy plastic models as these can damage easily.
  • Cutting width and height: Some cordless mowers are only usable on short grass, or will at least be less effective on tall grass. Make sure you know the cutting width and height you need and that mower is capable of reaching it. Cutting width is important for saving time, and battery, on large lawns.

Reputable brand names are another indicator of quality, Honda and STIHL are excellent but other ones include the following:

  • Black & Decker.
  • EGO.
  • Gtech.
  • Hyundai.
  • Kärcher.
  • Mountfield.
  • Stiga.
  • Yard Force.

This is not an exhaustive list, many companies make fantastic cordless mowers, but these brands are reliable and have a reputation for good quality products.
