What To Look For in a Lawn Aerator

If you’ve got a large area of grass, consider an electric aerator with a working width over 36 cm. Electric aerators require less manual labour, and often have a scarifying function, providing two services in one. For medium lawns, look for an electric aerator with a working width over 30 cm. You could also use a manual rolling aerator if you don’t want the hassle of cables. 

Speaking of cables, if you choose an electric aerator, look out for a power cable around 10 m long. This way, you should be able to avoid using an extension cable in most medium gardens. 

There are two methods of aerating, and depending on the condition of your soil, you’ll want either a hollow plug aerator or a spiked aerator. If your soil is very compacted, use a plug aerator. By removing plugs of soil from the ground, these aerators can dramatically improve drainage and create long-lasting aeration. 

Alternatively, to quickly aerate the lawn, use a spiked aerator. There’s no need to empty or unblock anything as you work, so the job takes less time. However, they’re not as effective on very compacted soil. You may also need to aerate more regularly.

In smaller gardens, you can use hand-tool plug aerators to save money. These are relatively slow to use, but work well on small patches of lawn. You might even consider spiked shoes so you can walk around the garden whilst aerating the soil. 

After researching various lawn aerators, I’ve gone with the Hyundai 1500W Electric Lawn Scarifier & Aerator as my top pick. With a 1500 W motor and the ability to both scarify and aerate the ground, this tool is perfect for those with a large lawn to maintain.

    The Hyundai HYSC1500E Electric Lawn Scarifier & Aerator is one of the best lawn aerators for medium and large gardens. It has a 2-in-1, working as both an aerator and a scarifier.

    This aerator has a 1500 W motor, five adjustable heights and a 10 m power cable. It’s designed to revitalise lawns, with the 20 hardened steel blades able to remove moss, thatch and dead grass. The 36 cm working width efficiently covers larger lawns.

    There are five working depths ranging from -12 mm to 10 mm and the depth can be controlled using a single adjustment lever. When working as an aerator, this machine cuts into the lawn to create air pockets. Generally speaking, it works well on -6 mm, any lower may dig up too much of the lawn.

    The scarifier function works very effectively as well, successfully pulling moss and thatch out of the grass. It has a 45 L collection bag which is a good size for larger spaces. Whilst it collects some of the debris, it’s often necessary to go over the lawn with a rake afterwards (as is the case with many electric scarifiers).

    In terms of storage, the design is very practical. The handles are foldable, as well as height adjustable, and the grass bag can be removed. At 11.5 kg, it’s reasonably lightweight and easy to move around.

    Assembly isn’t overly complicated, but takes slightly longer than you might expect. This is because the collection bag needs assembling and its frame can be difficult to insert. Therefore, putting this aerator together takes around 30 minutes.

    For an electric machine, it’s reasonably noisy at 102 dB, so you may need to use ear protectors. For reference, 100 dB is a similar level of noise to a hand drill.

    Overall, this 2-in-1 model represents great value for money and is wide enough to be used on large lawns. Both of its features work well, which isn’t always the case with 2-in-1 machines. For those with large lawns in need of both a scarifier and an aerator, this Hyundai model is my top recommendation.

    Pros

    • Five height settings, from -12 mm to 10 mm, whereas many aerators just have three or four
    • Can switch between aerating and scarifying without needing to use any tools (such as an Allen key)
    • At 11.5 kg it’s sturdy across bumpy ground but still easy to lift in and out of storage
    • Power cable is bright orange so you’re unlikely to accidentally run it over
    • Aerates and scarifies efficiently (both functions work equally well)

    Cons

    • Assembling the collection bag is fiddly and overall assembly therefore takes 30 minutes
    • Not all of the debris is collected by the bag and it may be necessary to rake afterwards
    • Fairly loud - operates at 102 dB

    If you’ve got a small to medium size garden and you’re after an electric machine, the Einhell GC-SA 1231/1 Electric 2-in-1 Scarifier And Lawn Aerator is well worth considering. This model works as both a scarifier and an aerator and has a 31 cm width.

    Performance-wise, this model is one of the best on the market for both scarifying and aerating your lawn. It has three working depths, a 28 L grass bag, and operates using a 1200 W motor.

    Although it’s less powerful than the Hyundai HYSC1500E aerator on paper, it doesn’t feel that way in the garden. The Einhell’s 1200 W motor could probably cope with larger gardens as well, even though the machine is designed for smaller areas.

    Both the aerator and scarifier functions work well. In most cases, this machine will aerate and scarify at the same time (depending on the height setting it is set to). The scarifier is very capable of removing large amounts of moss and thatch. There are 42 stainless steel claws on the roller which help produce this result.

    Swapping between the two rollers is straightforward, but an Allen key is required. Luckily, this Allen key is always at hand because it can be stored in a holder on the handle.

    As mentioned, this aerator has a width of 31 cm which is the narrowest of the electric models featured on this page. This makes it easier to manoeuvre around smaller gardens and tight spaces. It also keeps the weight down. At 9 kg, this model is easy to get in and out of storage, and lift up stairs if you have a multi-level garden. The adjustable handle height means that it can also be made comfortable for taller uses.

    It’s also an easy machine to assemble. It takes around 15 minutes to put together and all you need is a Phillips screwdriver.

    As you can see, there’s a lot to love about this machine. It’s relatively hard to find flaws with its performance, but there are a couple of points to mention in terms of design. Firstly, the power cable is only 4.5 m long, so an extension cable will almost certainly be required, and the 28 L collection box is also relatively small. For these reasons, despite its powerful motor, it’s only suitable for smaller spaces.

    Additionally, the power cable itself is black. Whilst other models have brightly coloured cables, this one is difficult to spot in long grass which is a bit of a safety hazard.

    Nevertheless, due to its power and performance, this is one of the best lawn aerators for small and medium gardens. Its 2-in-1 functionality works well, and it’s a simple machine to use.

    Pros

    • Can be assembled in around 15 minutes
    • Aerator and scarifying function both work well
    • Narrow 31 cm working width is easy to navigate around small gardens
    • 1200 W motor feels extremely powerful for such a small unit
    • Allen key can be stored in machine’s handle, ready to change between scarify and aerator function

    Cons

    • Short 4.5 m power cable - extension lead will almost definitely be required
    • Power lead is black so sometimes gets hidden in the grass posing a safety hazard

    Designed primarily for medium size areas, this VonHaus 2 in 1 Electric Lawn Scarifier and Aerator is a great budget option if you’re after an electric machine. It’s particularly useful as a scarifier, although the aerator works well in certain contexts.

    It has a 32 cm working width, making it suitable for small/medium lawns, and four depth settings ranging from 4-12 mm. There are two interchangeable rollers included, one for scarifying and the other for aerating, which need to be swapped out depending on the function you want to use. To swap the rollers, you use the included Allen key to undo two screws (and tighten them up again).

    This model has a powerful 1500 W motor and its scarifying function is very effective. It removes a large amount of thatch and dead grass from the lawn. The aerating roller isn’t quite as effective, though it will work well on lawns requiring more serious maintenance. The aerator churns up the grass, so it isn’t as practical to use on lawns that are already reasonably healthy.

    Weighing just 8.5 kg, this model is one of the lightest on the market. It also runs slightly more quietly than other electric machines on this list (though only just), producing 98 dB.

    Assembly takes just 15 minutes and it comes with a 28 L grass bag as well as a generous 10 m cable. The power cable is bright orange which means it is visible in the grass as well.

    Overall, I’d say this is a great product for lawn maintenance on a budget, and it will certainly improve the health of grass. However, it’s generally better suited to use as a scarifier than an aerator. It’ll help grass breathe by removing thatch and moss, but you may find that the aerator roller churns up the ground too much.

    Pros

    • Entire assembly process takes around 15 minutes
    • 1500 W motor is powerful and not prone to overheating when used for long periods
    • 8.5 kg is very lightweight so it’s easy to move in and out of storage
    • Quieter than most aerators or lawn mowers at 98 dB
    • 10 m cable is bright orange so easy to spot in the grass
    • It is easy to switch between the scarifying and aerating roller

    Cons

    • Aerating function isn’t as effective as the scarifying function
    • Need to undo screws to change between aerator and scarifier roller

    If you’ve got a small area of lawn that needs attention, a hand tool like the Yard Butler ID-6C Manual Lawn Coring Aerator is worth considering.

    This aerator helps revitalise the lawn by removing 2 x 1.27 cm plugs of earth each time it is pulled from the ground. The plugs are fairly sizeable, measuring 8.9 cm long, meaning air, water and fertiliser can all reach further down into the soil.

    Of course, it won’t do much in terms of removing thatch, but it’s a cheap, easy way to improve aeration on a small lawn.

    The handles are softly padded and the tines are reasonably sharp, sinking down into most soil types. Measuring 93 cm long in total, it’s comfortable for most users to use without back strain; however, it may be a little small for taller users. There is a wide foot bar which means you can push the tines into the soil using your bodyweight making this tool easy to use.

    One of the best things about a manual aerator is how little faff they are to use. This aerator can be taken out of the box and used instantly, there’s no cable to worry about nor complex assembly. It’s very lightweight and easy to store. Plus, it makes it easy to work freely around the garden with no power cord to worry about.

    In loose, crumbly soil, the plugs of earth should be easy to remove from the tines; however, clay soil often needs to be pushed out manually which can make the job take longer. Also, users have reported that the welding inside the tubes can sometimes cause the plugs to get stuck as well. Watering the soil in the days before aerating may make it easier to work with.

    Overall, this is one of the best lawn aerators in terms of comfort (if you’re after a manual tool). It’s a good length, with padded handles and a wide foot bar. Designed for smaller areas, this aerator won’t be for everyone. However, for those looking for a reliable tool that’s easily capable of removing large plugs from the soil, this model is well worth considering.

    Pros

    • No assembly required and product can be used straight away
    • Removes large 8.9 cm long plugs of soil which makes it very effective at aerating
    • Wide foot bar makes it easy to push into the ground
    • Cushioned handles are comfortable to hold for long periods of time

    Cons

    • Quite a slow method of aerating and best for small lawns
    • Only two tines so less efficient than other manual aerators
    • Metal welding inside the tines can protrude into the tube and can prevent the plug of earth from being pushed out of the top

    Although this Swardman Professional Stainless Steel Hollow Tine Lawn Aerator is more expensive than the other hollow tine aerators featured here, it’s been designed to last a lifetime. It’s made from pure stainless steel and has three tines that are easy to empty.

    This aerator works exceptionally well thanks to the design of the tines. They aren’t solid tubes, like most plug aerators, but are ‘open faced’ instead. This means that soil is very unlikely to get blocked in them, but it’s exceptionally easy to remove if it does.

    The tines are long, removing plugs of soil to a depth of 13 cm, and reasonably wide at 1.6 cm across. The holes they create allow water, oxygen and fertiliser to get deep into the soil and improve the health of your lawn.

    One of the best things about this aerator is how durable it is. The tines are easily replaceable if needed, and the body of the aerator is extremely solid. There’s a small area where you can place your foot so your weight will sink the tines into the soil.

    The only downside to this aerator is that the T-handle is a little narrow so users with larger hands may find it uncomfortable. There are no grips on the handles either, so it doesn’t quite offer the same comfort as padded tools.

    Nevertheless, this is one of the best lawn aerators if you want an efficient, manual tool. It’s a great choice for small lawns and its design helps avoid the blocked-tine problem of other hollow aerators.

    Pros

    • Tines are open faced so plugs of soil don’t get stuck
    • Removes long 13 cm soil plugs
    • Durable stainless steel construction
    • Tines are easily replaceable and can simply be screwed in
    • Foot bar makes it easy to push aerator into the ground

    Cons

    • Ground needs to be fairly damp for this tool to work
    • T-handle is quite narrow and may be uncomfortable for those with larger hands
    • Slow method of aerating is best for smaller lawns

    There’s no need to overcomplicate things when it comes to some gardening tools, and the Ames 4-Spike Lawn Aerator is a great example of when simplicity works well.

    This aerator is perfect for those who don’t have a lot of storage space, or are sticking to a smaller budget. Built for aerating small patches of lawn, this lawn aerator has four spikes that are simply inserted into the ground to allow water, oxygen and fertiliser to reach grass roots.

    It’s worth noting that this aerator isn’t ‘hollow-tined’. The 8 cm spikes don’t remove any earth, so the ground isn’t any less compact. However, it’s still very effective. The spikes are 6 mm wide and create holes that allow air, water and nutrients to get deeper into the soil. This type of aerator has an additional benefit over hollow tine models – there’s no need to remove plugs of soil from the tines after use. Instead, simply insert the spikes into the soil and remove.

    The design of this aerator also adds to its ease of use. The stirrup design is easy on your back and many people find these more comfortable to use than t-shaped handles. There’s a foot bar to push down on, easing the spikes into the soil. Even if you’re wearing wide shoes like wellies, you’ll have plenty of space to get a good grip.

    For those looking for a simple gardening tool on a budget, this is one of the best lawn aerators to go for. Whilst those with large lawns may prefer an electric aerator, this model is proof that you don’t need to spend a fortune on garden tools.

    Pros

    • A good option for aerating small areas of lawn at once
    • Spike aerator means there’s no need to remove soil from blocked tines
    • Easier to use than hollow tine aerators as the soil doesn’t need to be heavily watered first
    • Creates well-sized 8 cm holes
    • Easy to push into soil thanks to large foot bar

    Cons

    • Only suitable for small/medium gardens
    • Does not decompact the ground as no soil is actually removed

    One of the most efficient (and fun?) ways to aerate your lawn, these Ohuhu Lawn Aerator Shoes are wearable aerators. These spiked ‘shoes’ attach to the bottom of your regular shoes using velcro straps. Simply walk around the garden, and the spikes at the bottom will be pushed down into the soil under your weight.

    These shoes take a lot of effort out of a notoriously arduous task, and they can even be used at the same time as tackling other gardening jobs. For example, you can wear these shoes to aerate whilst you hang out the washing – taking on two tasks at the same time!

    There are 13 metal spikes on each shoe, approximately 5 cm long, which penetrate into all types of soil for efficient aerating. These spikes are also replaceable, just in case any get lost.

    The size of these shoe attachments is fully adjustable thanks to the Velcro straps. They can be adjusted to fit both male and female shoe sizes, although your shoes underneath should be secured very tightly to prevent them from coming off.

    Whilst these shoes are fairly easy to use, it’s worth noting that they work best if your lawn is watered thoroughly before use. When the soil is very dry, the spikes can be difficult to push into the ground. You’ll also need to get used to walking in these shoes, as it can be a little hard to maintain balance.

    There are anti-slip pads on the part of the shoe that connects to the sole of your own shoes, helping to prevent slipping.

    If you’re looking for a quick and easy way to tackle lawn aeration, these are some of the best lawn aerators available. They certainly offer a more interesting way to tackle the lawn, and they’re perfect for busy gardeners as well. You can tackle other tasks whilst simultaneously completing some essential lawn maintenance.

    Pros

    • Allows aerating to be done at the same time as other jobs in the garden
    • Anti-slip pads offer user good grip on your shoes even when the grass is wet
    • Versatile sizing - Velcro straps make them adjustable to any shoe size
    • Relatively easy to walk in once you learn the best technique
    • Good quality straps that are easy to fasten

    Cons

    • Shoes worn underneath must be secured very tightly to prevent them from coming off
    • Requires quite a lot of effort to pull your foot out of the ground whilst keeping your balance - can become tiring over time depending on condition of soil
    • Much easier to use if the lawn is thoroughly watered before use

    For an easier way to aerate the lawn than using a standard garden fork, this Rolling Lawn Aerator gets the job to be done with a simple push motion.

    It has 30 metal spikes in total, which are each 45 mm long, and works well to aerate moist ground. Alongside this, the aerator is 30 cm wide, so it’s narrow enough to manoeuvre around smaller areas. As a result, this is one of the best lawn aerators for small gardens.

    In terms of effectiveness, this aerator needs to be used on damp/moist ground in order to give a good result. This is because it’s relatively light, at 2.8 kg, so the spikes don’t easily penetrate hard ground. It’s either necessary to wait until after rainfall, or water the ground first, before aerating.

    The metal spikes are tough and strong, so produce good results, but assembling them on the aerator can take a while. Assembly is probably the biggest downside to this unit, as the supplied spanner is very low quality and several additional tools will be required.

    There are instructions included, but they’re not overly clear, and a lot of patience is needed to screw all of the pieces together. Some customers have cited a total construction time of between 40 minutes and two hours.

    Assembly aside, this aerator has the potential to be effective and improve the appearance of the lawn. The most important thing to bear in mind is the hardness of the soil whilst using it. It can be used on denser, clay-based soil as well, but again – this needs to be sufficiently damp first.

    Pros

    • Narrow 30 cm width makes it easy to manoeuvre around smaller gardens
    • Large metal spikes are high quality and durable - strong enough to take the pressure of being pushed into the ground
    • Handle can be removed to make storage easier
    • Long handle helps avoid having to stoop whilst using

    Cons

    • Supplied tools for assembly are slightly low quality so you'll need to use your own tools
    • Assembly can take a long time, up to two hours, and require a lot of patience
    • Quite lightweight so doesn't push down easily into the ground, especially if it's too firm

How to Choose The Best Lawn Aerator

Lawn aerators improve the appearance of grass over time by penetrating the ground and allowing air and water deeper into the soil. As a result, the roots have better access to nutrients and fertilisers.

There are different types of aerator available, which can produce different results. Below, you will find information about how and when to use an aerator, as well as how to choose the best lawn aerator for your garden.

Benefits of Aerating the Lawn

Aerating the lawn can be beneficial in several ways. The effects can also vary depending on what type of aerator you are using.

If you’re planting new grass seed, aerating before sowing the seeds can give them the best possible start. This is just as true when overseeding as when planting grass seed for the first time.

Loosening the soil, improving the supply of oxygen, and creating good drainage creates a good environment for new grass seed, whilst benefitting any existing lawn.

Using spiked aerators that pierce the ground will allow air to reach grass roots as well as water. Grass roots will become stronger which will lead to a healthier lawn that’s better able to withstand heat and drought. 

Creating pockets that air, water and fertiliser can get into can help improve your lawn’s uptake of nutrients.

If the aerator removes plugs of soil, it will make the soil less compact. This can help grass roots to establish, if they have become overcrowded, improving the health of the grass.

Removing plugs of soil can also help with drainage in compacted ground. If the ground is too compact, water can end up sitting on top of the soil, unable to drain. Not only can this make the garden unpleasant to walk in, but it can damage the grass and soil. Removing plugs of soil will help water drain better.

Some people choose to fill the plugged holes with sand in order to alter the composition of the soil and improve drainage and aeration throughout the area. The sand will eventually spread throughout the soil, carried by worms and ground movement, resulting in a better mix.

Whether this will be beneficial for your soil or not can depend on what type of soil you have. Adding sand to clay soil can cause it to lump together more, not less.

Choosing the Right Type of Aerator

There are 3 main types of aerator on the market – spike aerators, tine aerators and spiked aerator shoes.

Spike aerators are the most popular type of aerators. Many are simply pushed across the lawn. As the roller rotates, the spikes are pushed into the ground. Spike aerators are either manual or electric.

Spike aerators don’t remove any earth, so they don’t make the ground less compact in the same way as plug aerators. However, they still make holes that allow air, water and nutrients to get closer to the lawn roots. Manual spike aerators can be quite light, which makes it more difficult to keep the spikes in the ground.

Some people choose to add weights to the handles of these aerators in order to push them down. Electric aerators tend to be slightly heavier, because they have a motor.

Plug aerators have hollow tines and are usually pushed into the ground using your feet. They remove plugs of earth as opposed to just penetrating the soil. These are more effort to use, although they have the benefit of actively removing the soil, as opposed to just pushing it to the side.

Removing plugs of soil makes the ground less compact and also means that the holes can be filled with sand or a different soil, if you are trying to alter the composition of the ground. If parts of your garden frequently flood, you may benefit from removing plugs of soil, in order to make the ground less compacted.

Finally, there are spiked aerator shoes. These are definitely the best option for those who are looking to up their step count! They’re worn on your feet and will aerate your lawn as you walk around. They can also be worn whilst doing other jobs, like mowing the lawn, in order to multitask.

Whilst not the most comfortable of shoes, they can be slipped on over gardening boots without much difficulty. They usually have adjustable straps so will fit almost any shoe size.

Ease of Use

Electric or petrol-powered aerators are the least physically demanding aerators. The motor will do the brunt of the work. However, they are generally more expensive, and require more maintenance, so they’re only worthwhile if you intend to aerate frequently over larger areas.

Plug aerators can be more tiring to use than rotary spiked aerators. Pushing a plug aerator into the ground can require quite a lot of force, as can pulling it out again. A certain amount of upper body force is required, and this method can be too physically demanding for some people.

Using a rotary spiked aerator is less physically demanding than a plug aerator, as long as the ground is sufficiently soft. They can still be relatively hard work to push, especially as they need to be driven into the ground. As mentioned above, putting weights on a spiked aerator can help, but of course this will make it more taxing to push.

Spiked aerator shoes require a bit of getting used to, and some leg muscle as well, to pull the spikes out of the ground. But they can be a good way to cover small areas. You just need to be careful not to wear the shoes on any hard surfaces, as the spikes can bend and break. These shoe aerators won’t create as deep a hole as other types.

Lawn Aerator FAQs

When is the best time to aerate my lawn? 

Most lawns will benefit from being aerated on an annual basis, although those that are used heavily may require an additional aeration. New lawns will need to be aerated more often.

There are two ideal times in the year for aerating the lawn: the first is in the spring and the second is in autumn.

During the spring and autumn months, the soil is moist which makes it easier to aerate. Spring coincides with the growing season of the grass, so aerating your lawn in the spring tends to produce better results.

It’s worth keeping an eye on the weather when deciding to aerate. If it’s too wet, the holes will seal quickly so aerating has very little benefit. However, most of the time the problem is that the ground is too dry – it can be necessary to water the soil before aerating.

Should I pick up plugs after aerating? 

It’s best to leave the plugs on your lawn if you’ve used a plug aerator. They are full of nutrients and will be broken down on their own after a couple of weeks. If you’re concerned about your lawn looking messy, watering the plugs can help them break them down a little faster.

Which is better: a spike or plug aerator? 

Spike aerators have sharp tines that penetrate the ground, while plug aerators remove a plug of grass from the soil.

In terms of which is better, this depends on the size of your garden and the soil. Spike aerators provide short term soil decompaction. They are suitable for small gardens and they don’t create any mess on your lawn.

Plug aerators remove small plugs of soil. This means they do a better job aerating, and they provide a more long term decompaction as air spaces are created around your lawn. Plug aerators are suitable for larger lawns with a lot of soil compaction, although they do create more mess than spike aerators – as the plugs are left scattered around the lawn.

Can I mow my lawn after aerating? 

It’s important not to mow your lawn immediately following aeration. Instead, you should seed and fertilise to make the most of the holes you have created in the lawn. I recommend not mowing your lawn for at least 2 weeks following aerating and overseeding.

If your lawn desperately needs a mow, you’re better off mowing before you aerate.

How big should the holes be when aerating?

The holes in your lawn should be between 1.5 – 3 cm deep, although some electric aerators have adjustable depths. Ideally the holes should be around 1 cm in diameter.

It’s also important the holes are correctly spaced. For best results, aim for each hole to be under 4.5 cm apart.
