5. Best self-propelled cordless lawn mower: Greenworks Cordless Self-Propelled Lawn Mower

A self-propelled lawn mower comes with a motor that moves the mower for you so you don’t need to push, which makes mowing the lawn a far less tiring activity.

The Greenworks Cordless Self-Propelled Lawn Mower has variable speed control, so you can adjust the speed to your own specific walking speed and set your own pace.

This professional lawn mower also has a nifty side ejection facility. You decide whether you want to mulch while lawn mowing, then the lawn cuttings are mulched and evenly distributed from the side of the mower, leaving the soil enriched with nutrients and protected from drying out. Plus, you save yourself the trouble of emptying the grass catcher box.

But while it may be smaller than some cordless mowers, it still packs a punch when it comes to lawn mowing efficiency. Thanks to two 20v batteries, it’s got more power than most other cordless lawn mowers and will make short work of any patch of grass, although the smaller cuttings box means it’s definitely more suited to smaller lawns.

8. Best cordless lawn mower for large gardens: Murray Cordless Lawn Mower

Affectionately referred to as ‘The Beast’ by its fans, this heavy-duty cordless lawn mower by Murray makes short work of huge lawns thanks to its phenomenal performance, wide blades and exceptional battery life.

But while it might be great for heavy-duty jobs, it’s actually relatively light in itself, weighing in at just 14kg.

The 50-litre grass collector bag allows for high air flow and easily detaches from the mower, while the 25cm high rear wheels enable you to manoeuvre easily across all terrains.

Pros

9. Best cordless lawn mower for stripes: Bosch Advanced Rotak 36-850 Cordless Lawn Mower

However great, a cordless mower weighing in at only 16kg is never going to give you the bold stripes you can achieve with a heavy steel roller attached to a petrol lawn mower. But if your lawn is already in good shape, then the superb Bosch Rotak will definitely do its best.

What’s more, this well-loved mower produces up to 60% reduced noise thanks to Bosch’s ProSilence technology, an excellent feature if you’re up with the larks and want to crack on with the gardening but don’t want to annoy the neighbours.

Another added bonus is that this cordless lawn mower comes with two batteries, but only needs one to run on, so you can have one charging while you start and swap them over when the first runs out – super helpful if your lawn is larger than average.

Pros

  • Great for stripes
  • Quiet
  • Comes with two batteries but only needs one to run

Cons

  • Expensive
  • Some customers report that it’s difficult to turn

Are cordless lawn mowers worth it?

If you’ve ever wrestled with a large electric mower and had to keep track of trailing cables in case you slice through one, then a cordless lawn mower will feel like a breath of fresh air.

A lawn mower with a petrol engine can be heavy, messy and smelly, whereas a cordless mower is lightweight, quiet and an all-round simpler and more efficient tool to use.

Cutting efficiency and quality is as good on a cordless mower as any corded or petrol mower, so the main consideration for most prospective buyers is battery life.

As such, there’s no reason why a cordless mower can’t take on anything a petrol or electric mower can. Add in the convenience of simply popping in a battery versus filling up a petrol tank or wheeling out extension cables, and we think it’s a no-brainer. Go cordless and you’ll never look back!

How to choose the best cordless lawn mower

  • How large your lawn is: A small lawn will not require a lawn mower with as much power, cutting width, battery life or grass cuttings capacity as a large garden. Cordless lawn mowers with a cutting width of 32cm or less won’t be suitable for big lawns.
  • How heavy the mower is: If you struggle to lift and carry a lawn mower, then consider the weight when buying.
  • Whether it’s self-propelled: If you’re physically restricted in any way, it may be worth considering buying a self-propelled mower, which moves by itself, limiting the input you need to make.
  • Do you want a striped lawn? If so, you will need a mower with a rear roller.

How long do cordless lawn mower batteries last?

No one wants their cordless lawn mower to run out of juice halfway through the job. Battery life is a difficult thing to judge and, for this reason, most manufacturers stop short of giving estimations.

This is because the length of running time that a battery can give varies a great deal depending on the circumstances.

If your lawn is long, thick, bumpy or wet then you may find that your mower has to work twice as hard and therefore uses considerably more power.

If you have a small to medium-sized lawn, then almost all lawn mowers will be able to mow it easily on just one charge. A larger lawn may require a battery change.

Some cordless lawn mowers are more suitable for larger lawns. We recommend the Murray Cordless Lawn Mower which makes short work of large areas of grass.

One thing to remember is that additional lawn mower batteries can be purchased separately, so if you find your mower isn’t quite making it to the end of the job, you can always have a spare battery on hand.

Which is the best cordless lawn mower?

We’ve researched the huge range of cordless lawn mowers on the market and the best cordless mower is the Makita DLM431Z Lawn Mower, a superb all-rounder with a smooth finish and large-capacity grass cuttings box and loved by hundreds of happy customers.
