What is the Best Lawnmower for 2021?

Lawnmower Buying Guide

With Spring just around the corner, and the weather set to pick up, it's time to think about making the first grass cut of the season. For many, mowing the grass can be an enjoyable experience, but with the wrong lawnmower, it can quickly turn into a chore.

Lawnmowers are an essential garden tool. They are used multiple times a year, and often for years to come, so it is important to choose a quality model that will last and produce great results time and time again. In this Toolstop guide, we compare petrol, electric and cordless lawnmowers, explaining the pros and cons of each and recommend some of our top picks for best lawnmower for 2021.

Electric, Cordless or Petrol Lawnmower?

There are so many different models of lawnmower on the market today; cordless, electric, petrol, hand mowers. Each serves the exact same purpose - to cut grass. So which one should you opt for? Inevitably, this is dependent on the application you need it for. Ask yourself - How big is your garden? Will a cable stretch far enough? How much budget do you have to play with... etc. Below we have highlighted the pros and cons of each type of lawnmower.

Cordless Lawnmowers: Cordless lawnmowers give you the freedom to roam anywhere around the garden. Big or small, you won't need to worry about trailing cables getting in the way or not stretching far enough. They are often the most lightweight and compact option, allowing for easier storage and transportation. But, as they are powered by a lithium-ion battery, you risk them running out of charge. Of course, they are designed to be used for this purpose, so they do have great runtimes, but depending on the size of your garden, they may not be the best option for you. If you are using them on a larger scale, you will want to check how many minutes of runtime you can achieve or the area the lawnmower can cover before running out of charge. We always recommended you have a fully charged backup battery at the ready for this reason.

Electric Lawnmowers: Electric lawnmowers can be powered all day long. Use them for your front garden, back garden, neighbours garden, you name it without running out of charge. But, a major downside to electric lawnmowers is the cable. Cables often won't stretch far enough and can get in the way when in use which can be dangerous. Of course, the cable on a lawnmower is longer than that of a standard power tool as they are designed to be used in larger spaces, but an extension lead may be needed to allow you to cover the full area of your garden (depending on the size). An electric lawnmower may not be the ideal choice for a professional gardener as accessing a power supply may be difficult at times, but for home gardening, they are usually a great option. Electric lawnmowers are typically in the mid price range and don't require any maintenence. Simply plug it in and you're good to go!

Petrol Lawnmowers: Petrol lawnmowers are extremely powerful, though they are often the noisiest option. Petrol is extremely accessible, but it is also expensive. Think about an electric or cordless lawnmower, it is a one off purchase. Whereas with a petrol powered lawnmower you will be required to replace the fuel regularly (depending on how often your grass needs cut). Petrol mowers are often the best choice for larger lawns, or the professional gardener. They are typically the most powerful option making them better adapted to dealing with more demanding applications.

Push Mowers: Push mowers are extremely eco friendly. They require absolutely no power, so can be used anywhere and everywhere, no matter the size of area you need to cover. They are typically better suited to smaller gardens as they require a lot of work from the user. Push lawnmowers are not recommended for long grass or cutting on slopes.

So to conclude, it really does depend on the application. If you are working on an industrial scale or are a professional gardener, petrol is probably the best option as you can top it up for power all day. For average sized gardens, it is down to personal preference. Will a cable stretch far enough? Will you remember to charge the batteries? Once you have weighed up the pros and cons of each, you should be able to come to a logical decision based on which will work best for you.

Other factors to consider when buying a lawnmower

Another important factor to consider is the size of the lawnmower. Does it have an adjustable handle? If you are tall/small, this may be a deal breaker for you. Does it fold up to become nice and compact? If so, it will be easier to store during the colder months and when not in use. What is the cutting height? A lot of lawnmowers have an adjustable cutting height. Essentially, this determines how short it will cut the grass. And what about cutting width? The wider the cutting width, the less time it will take to cut your grass as the lawnmower is covering a larger area at a time. But again, the wider the cutting width, the bulkier the model. Price - is it within your budget and will you get your money's worth? Lawnmowers are large garden power tools, so inevitably, they come at a price. But fear not, you can take advantage of our finance options at Toolstop.
