The best lawn aerators, compared.
Top pick: Colwelt 4-spike plate Best value: Colwelt 4-spike plate – The same score of 82, at about £26.56, from 4.6 and 535 reviews. It is the cheaper of the two tied scores. Updated 22 October 2026.
A lawn aerator makes holes in turf so air, water and nutrients can reach the roots, and so compacted ground has a chance to drain. In the UK you usually do this in autumn, or in spring if autumn was missed, when the soil is moist rather than dusty or sodden. For most lawns every two to three years is enough. The useful difference is whether the tool pulls a plug of soil out or only pushes a solid spike in. Hollow tines suit clay and lawns that puddle. Solid spikes, including shoes and rollers, suit a lighter seasonal prick and can press clay sideways instead of opening it. A footplate has to take your weight in boots. A shoe has to stay on while you lift your feet. If you cannot see soil between the grass blades, the thatch comes off first, because an aerator does not remove moss. The [hollow tine or solid spike](/hub/lawn-and-garden-equipment/lawn-aerator/sub/lawn-aerator-hollow-or-spike) check is the one that changes the tool. Stop if the area needs a machine, a drain, or more strength than you have.

Personal buying guide
Question 1 of 2
What is the lawn doing?
The Colwelt is a four-spike solid plate, spikes listed at 9 cm, handle 96 cm in the title, weight 1.95 kg, price £26.56, with 4.6 from 535 reviews and rank 9 in Manual Lawn Aerators. The package line is 41.5 x 27.5 x 6.4 cm, so that is the box, not the standing tool. Bullets say this style suits lawns that are not badly compacted. UK reviews still report a heavy clay lawn and a dip that floods, and several people prefer it to a fork because the footplate is kinder. It ships in pieces. The sampled reviews do not show a bend-or-snap pattern. The listing-confidence score is 82, the same as the Walensee. It is the best-value badge because it is the cheaper of the two tied scores and it is not the top pick. It remains a solid-spike tool.
Pros
Cons
Best for: You want the cheaper of the two 82-point solid-spike plates, with four 9 cm spikes and a wide footplate, for a lawn that is not badly compacted.
Less suitable: You need plugs removed from heavy clay, or the lawn is large enough that a reviewer wanted a machine instead.
Specifications
Common questions
How many spikes, and how long?
Four solid steel spikes, listed at 9 cm. The title says a 96 cm tool. The 41.5 x 27.5 x 6.4 cm line is the package, and the weight is 1.95 kg.
Is it for badly compacted clay?
The bullets say four longer spikes have less impact and suit lawns that are not badly compacted. UK reviews still include a heavy clay lawn and a dip that waterlogs. It does not pull plugs.
What is the star rating?
The listing says 4.6 from 535 reviews, rank 9 in Manual Lawn Aerators, £26.56.
The EYMPEU is a 15-spike plate with six springs the bullets say you can remove, listed at £31.99 with 4.6 from 9 reviews and rank 34 in Manual Lawn Aerators. Handle positions are 83.5 cm, 87.5 cm and 91.9 cm. The spec line says 2.24 kg and 11 x 26 x 91 cm, model WAEU2603192UK. The saved listing holds one UK review, which says assembly was easy and the tool felt sturdy. There is no criticism in that review, so the criticism line stays empty rather than invented. A 4.6 on nine reviews would look like a top pick if you ignored the sample. The listing-confidence score is 66 because a count under 10 takes eight points off. Do not treat this row as proven durability.
Pros
Cons
Best for: You want a 15-spike plate whose springs can come off, and you will treat nine reviews as too small a sample to prove durability.
Less suitable: You are choosing on the 4.6-star line alone, or you need a tool with a published criticism sample rather than one short UK review.
Specifications
Common questions
Can you remove the springs?
Yes, according to the bullets. Six springs can stay on for a self-cleaning bounce or come off for a rigid press. That is still 15 solid spikes, not hollow tines.
What handle heights are listed?
83.5 cm, 87.5 cm and 91.9 cm. The spec line says 11 x 26 x 91 cm and 2.24 kg. Model WAEU2603192UK, part 01B.
How many reviews support the 4.6?
The listing says 4.6 from 9 reviews. The file itself contains one short UK review. The sample bump in the score treats a count under 10 as a penalty.
The Walensee is a 15-spike solid step plate, listed at £35.99 with 4.4 from 2,778 amazon.co.uk reviews, rank 4 in Manual Lawn Aerators on the raw capture. Bullets say the spikes are 5.8 cm and the tool is 88 cm. The spec line instead prints 9.2 x 3.9 x 34.6 cm and 2.04 kg, which reads as a parcel, so the working height is not settled by the spec line. There is no spring. UK reviews praise an easy build and real penetration once the lawn is damp, and they complain about the included spanners and about the effort if you have a bad back. The listing-confidence score is 82, tied with the Colwelt. The tie breaks to this row on review count, which is why it carries the top-pick badge. It still only makes solid holes. On clay that needs plugs removed, it is the wrong mechanism.
Pros
Cons
Best for: You want a widely reviewed solid-spike step plate for a small damp lawn, and solid holes are enough.
Less suitable: You need plugs pulled from clay, you have a bad back, or you expect the spec line to confirm the 88 cm height in the bullets.
Specifications
Common questions
Does it need assembling?
Yes. The listing includes a T-handle, a pole, a foot pedal, two bolts, two nuts and two spanners. UK reviews call assembly easy, and some say the supplied spanners fit badly.
How long are the spikes?
The bullets say 15 sharp tines, 5.8 cm long, on a powder-coated iron head. The spec line lists 2.04 kg and parcel-style dimensions of 9.2 x 3.9 x 34.6 cm, which do not match the 88 cm length in the bullets.
Will it go into hard ground?
The listing says to water hard, dry soil first. UK reviews agree it is hard work on dry summer ground and easier after rain or watering.
The Dolibest is the only dedicated hollow-tine tool in this set: four semi-open prongs, listed at £44.99 with 4.4 from 137 reviews and rank 5 in Manual Lawn Aerators. Bullets claim a core 12.2 cm deep and 1.5 cm across and a 93 cm shaft. The spec line says 65 x 43.18 x 27.94 cm and 2.3 kg, so the length is in conflict. The material line names steel, stainless steel and plastic, while the bullets say powder-coated metal. UK reviews include a heavy-clay user who did not have to clear the tines until the end of a session, and another who says the tubes clog after two or three presses and then only spike. A split shaft held by two bolts is a separate worry. The listing-confidence score is 78. On the RHS clay method this is the row that can pull a plug, if the tubes stay clear.
Pros
Cons
Best for: You want the only dedicated hollow-tine tool in this set, for clay where a plug has to come out, and you will clear the tubes if they clog.
Less suitable: You want a quick solid prick, or you will keep pressing after the semi-open tines block and start behaving like spikes.
Specifications
Common questions
Does it remove plugs?
The bullets say four semi-open holes, a core 12.2 cm deep and 1.5 cm across. Some UK reviews say cores eject sideways even in clay. Others say the tubes clog after two or three presses and the tool then only makes holes.
Is it stainless steel?
The material line lists steel, stainless steel and plastic. The bullets say powder-coated metal. The listing does not give a stainless grade.
How long is the shaft?
Bullets say 93 cm. The spec line says 65 x 43.18 x 27.94 cm and 2.3 kg. Both figures are in the saved listing. They do not describe the same shape.
The Jardineer is a 12-spike solid step plate, model UK1130, listed at £26.99 with 4.3 from 184 reviews and rank 7 in Manual Lawn Aerators. The spec line says 2 kg and 38.5 x 27 x 13 cm. Bullets sell it as safer than aerator shoes and say spare spikes are included. UK reviews are mixed on that promise: some boxes had spare bolts and prongs, others did not. Several reviews say spikes bent during a single session, including on a small lawn. Reviewers who got it onto damp ground say it beats shoes and a fork for a compact patch, and one names a lawn of about 52 square metres. The listing-confidence score is 77. Bent tines are the durability limit at this price, not a reason to treat it as a hollow-tine tool.
Pros
Cons
Best for: You want a 12-spike plate around £27 for a compact damp patch, including a lawn of about 52 square metres if the tines stay straight.
Less suitable: You need hollow cores, or you are treating it as a long-term tool after reviews that describe bent spikes in one session.
Specifications
Common questions
Are spare spikes in the box?
The bullets say spare spikes are included. More than one UK review says they were missing. Another review did find spare bolts and prongs. Check the box against the sheet.
Is it a corer?
No. It is a solid-spike plate with 12 spikes on a steel footplate, listed at 2 kg, model UK1130. The parcel line is 38.5 x 27 x 13 cm.
Do the spikes bend?
Several UK reviews say spikes bent during use, including two that bent halfway across a small lawn and three screws bent in half by the end of a garden. The listing includes spares in the text, which some buyers did not receive.
The Ohuhu shoes are solid spikes on a die-cast aluminium base, spikes listed at 5.5 cm, base about 30 x 13.5 cm, weight 1.23 kg, model Y11-88000-53, price £23.99. The listing says 4.2 from 2,748 reviews and rank 1 in Manual Lawn Aerators, the largest popularity signal in this set. They are listed pre-assembled. Reviews say wear boots, lift your feet, tighten loose spikes with the small spanner, and expect a strange walk. Complaints include blisters, a poor fit at UK size 5, and balance bad enough that one person used crutches. Praise is that the metal base feels stronger than plastic shoes and that body weight drives the spikes better than a light roller. The listing-confidence score is 79. Thrive's published view of this product type is that shoes are hard to balance on and not very effective. That is type guidance, not a lab result on this pair. They do not pull plugs.
Pros
Cons
Best for: You want solid 5.5 cm spikes you strap over boots for a small patch, and you will lift your feet and accept an odd walk.
Less suitable: You need plugs pulled, the fit is poor at a small shoe size, or balance and blisters are already a problem.
Specifications
Common questions
Do they need assembly?
The bullets say pre-assembled, hook-and-loop, base about 30 x 13.5 cm, spikes 5.5 cm. A review says use the supplied spanner on factory-loose spikes. Three spares were in that box. Weight listed 1.23 kg.
What should you wear?
Reviews say boots, tied tight. One buyer in ordinary shoes got blisters. One UK size 5 buyer says one-size is not accurate. Several say your foot sticks until you lift it.
Are they hollow tines?
No. They are solid spikes you walk in. The listing is 4.2 from 2,748 reviews and rank 1 in Manual Lawn Aerators, at £23.99. Rank is popularity inside a mixed category.
The seasky is a 15-spike spring plate, listed at £36.99 with 4.2 from 238 reviews and rank 14 in Manual Lawn Aerators. Bullets say the spikes are 2.8 inches and that they retract into the panel at rest. The spec line says 2.47 kg and 27.94 x 12.7 x 96.52 cm, with an adjustable height of 28 to 38 inches. Model STQ-101 and part HF-101 both appear. UK reviews call it sturdy enough for a small lawn and say the holes are narrow and easy to miss. One review would not trust it on a hard compact lawn. The seller's own tip is to wait if the ground is muddy and to water and wait if it is baked. The listing-confidence score is 75. Same solid-spike family as the Walensee, with a spring, at a similar price and a smaller review count.
Pros
Cons
Best for: You want a 15-spike spring plate whose spikes retract into the panel at rest, for a small lawn where narrow holes are acceptable.
Less suitable: The lawn is hard and compact, or you want the much larger review sample of a similar solid-spike plate.
Specifications
Common questions
Do the spikes stay covered?
The bullets say that when the tool is not in use the spikes retract into the panel. That is a spring-plate claim, not a hollow tine.
How long are the spikes?
The bullets say 15 spikes, 2.8 inches long. The spec line says 27.94 x 12.7 x 96.52 cm and 2.47 kg, model STQ-101, part HF-101. Height is also given as 28 to 38 inches.
When should you use it?
The bullets say wait if the soil is muddy, and if it is dry and hard, water and wait a few days. Reviews add that the holes are small.
The GINELSON is a 15-spike iron step plate with a spring-loaded plate, listed at £29.99 with 4.0 from 29 reviews and rank 20 in Manual Lawn Aerators. Weight is 2.29 kg, finish baked enamel, colour orange, origin China, model YIJINGYG04S. The title says pre-assembled. Reviews describe several bolts, awkward access between the spikes, and one unit whose holes were offset. The spring clears debris and covers the spikes. It does not extract cores. Reviews say the spikes reach full depth on moist ground and stop short on baked July soil. Spikes are described as very sharp. The listing-confidence score is 64. The review count is under 30, so this row is a thinner sample than the Walensee or the Colwelt.
Pros
Cons
Best for: You want a spring plate that knocks soil off 15 spikes on moist ground, and you will treat 29 reviews as a thin sample.
Less suitable: You need cores extracted, the ground is baked hard, or you want a review sample in the hundreds.
Specifications
Common questions
Is it pre-assembled?
The title says pre-assembled. UK reviews say you still bolt the handle and the head, with spanners supplied, and that the bolts beside the spikes are awkward.
Does the spring remove soil cores?
No. Reviews describe a spring plate that pushes soil and grass off solid spikes and covers the spikes afterwards. It does not pull a plug.
How heavy is it?
The listing says 2.29 kg, iron with a baked enamel finish, colour orange, made in China. Model YIJINGYG04S.
The Taylor & Brown is the only push roller in this set, listed at £19.99 with 3.9 from 146 reviews and rank 3 in Manual Lawn Aerators. The bullets give a 45 cm drum, a 122 cm three-piece handle and a 14.5 cm wheel, and they claim about 184 holes per square metre. That hole count is a seller figure. The material line does not say stainless. UK reviews split: some find it easier than a fork on damp grass, including one reviewer aged 65, and others say the axle nuts either lock solid or fall off, the handle wobbles, and the drum is too light unless you add weight. One reviewer strapped on a 5 kg dumbbell. That is a user modification, not a listed feature. The listing-confidence score is 70. It is a solid-spike tool you push, not a hollow-tine corer.
Pros
Cons
Best for: You want to push a 45 cm spiked drum across damp grass instead of standing on a plate.
Less suitable: You need hollow cores, or you will not add weight and check the axle nuts before the roller locks or falls apart.
Specifications
Common questions
Is it stainless steel?
The listing does not say stainless. Bullets say a steel tube and a metal protection guard.
How wide is the roller?
The bullets say 45 cm wide, a 122 cm handle and a 14.5 cm wheel. The spec line says 122 x 45 x 21 cm. A seller line claims about 184 holes per square metre. That figure is not a measurement in the saved listing.
Do I need to add weight?
Several UK reviews say it is light and penetrates better with extra weight. Others say the axle nuts either lock the roller or undo completely.
The ZUCKLIGHT is a 16-spike spring plate, spikes listed at 9 cm, two handle heights at 76 cm and 98 cm, weight 2.8 kg, colour black and yellow, origin China, model LA-2, price £36.99. The listing says 3.8 from 77 reviews and rank 11 in Manual Lawn Aerators. Bullets call it pre-assembled for lawns under 300 square metres. That area is a seller ceiling. Reviews describe real assembly, a tip to fit spring bolts thread-up so the nuts stay visible, a handle that broke in two during use, and turf pulled up on semi-moist ground. Other reviews say it does the job after proper rain, and one person used it across a full day. The listing-confidence score is 65. A broken handle is a durability complaint, not a technique.
Pros
Cons
Best for: You want a 16-spike spring plate with two handle heights, and you will use it after proper rain on an area you can finish by hand.
Less suitable: A review already describes a handle that broke in two, or the ground is only semi-moist and tears turf up.
Specifications
Common questions
Is it pre-assembled?
The bullets say pre-assembled and that you attach the handle. Reviews describe a harder build, including which way the spring bolts should face and how tight the spikes should be.
What are the handle heights?
76 cm and 98 cm. Spikes are listed at 9 cm, 16 of them. Weight 2.8 kg. Colour black and yellow. Model LA-2. Origin China. Price £36.99.
Why did grass come up?
One UK review on semi-moist ground says the spikes pulled chunks of turf out. The seller ceiling of 300 square metres is a bullet, not a trial.
The CAKKVDE is listed as a mixed head, 16 spikes and 8 core plugs, at £20.99 with 3.6 from 15 reviews and rank 32 in Manual Lawn Aerators. The spec line says 2.53 kg and 25.4 x 12.7 x 98 cm. Bullets promise tool-free assembly and a cleaning tool. Reviews describe a 10 to 15 minute bolt-up, sometimes with no instructions, a plug-removal implement in at least one box, a weld that broke before the lawn was finished, and a handle that broke away after a couple of uses. Other reviews call it sturdy on damp ground and useless on a dry lawn. The listing-confidence score is 58, the lowest in this set. A mixed claim at this price is not evidence that both mechanisms work. The review count is the whole visible sample and it is small.
Pros
Cons
Best for: You are looking at a low-priced head that claims both spikes and cores, and you will judge the welds and the bolt-up rather than the dual claim.
Less suitable: You need both mechanisms to work, the lawn is dry, or a 15-review sample that includes a broken weld is already a reason to skip it.
Specifications
Common questions
Does one head both spike and core?
The bullets say 16 spikes and 8 hollow tines, plus a cleaning tool. A review mentions an implement for removing plugs. The saved listing does not show a measured core length.
How tall is it?
The spec line says 25.4 x 12.7 x 98 cm and 2.53 kg. Bullets say an adjustable 38 inch height. Part MLA 1PACK, model MLA, £20.99.
What failed in reviews?
With 3.6 from 15 reviews, the file includes a weld that broke mid-lawn and a handle that broke away after a couple of uses. Other reviews say it is sturdy if the soil is damp. Both are in the saved listing.
Scores are listing confidence for the 11 amazon.co.uk listings kept on 19 October 2026. The published method is the star line, round(stars times 16). Review-count bumps, and the penalty when fewer than 10 reviews sit behind the stars, are point adjustments, not separate percentage weights. Equipment, price and review sentiment are recorded and are not added as points. Shelf price decides the best-value badge only after the scores exist. This is not a lawn trial.
Amazon.co.uk star line
100%The score file publishes one numeric base: the amazon.co.uk star line, as round(stars times 16). A review count of 1,000 or more, 100 or more, 30 or more, 10 or more, or under 10 changes that score by a fixed point adjustment. Those adjustments are not weights. The digest lists soil, tine type, lawn size, box contents and the review sample as buying checks, with no percentages, so they are not rescaled to 100.
Start with the soil, not the spike count. A screwdriver that will not go in means compaction. Water sitting on the grass means drainage. No soil visible between the blades means thatch, which is scarifying. On clay or a lawn that waterlogs, a hollow tine is the preference in the RHS autumn guidance. A solid spike is enough for a lighter prick on a small lawn. Hand tools suit a small area or the worn paths. Shoes need balance. A step plate needs your weight.
A lawn aerator makes holes in turf so air, water and nutrients can reach the roots, and so compacted ground can drain. It is not a scarifier and it is not a mower. If you cannot see soil between the grass blades, the thatch is the first job. Moss is removed by scarifying, not by punching holes. The RHS treats compaction, standing water and thatch as different problems. A screwdriver that will not enter the ground is a simple check for compaction. Standing water is a drainage problem.
The useful difference is whether the tool pulls a plug or only pushes a solid spike. A higher spike count does not turn a solid plate, a shoe or a roller into a hollow tine. A spring only knocks debris off.
Baked soil will not take the tines, and still-flooded ground should be cleared first. Do not walk a frosty lawn. Let thatch come off before you punch holes, or it falls into them.
Spare spikes are not always in the box, and pre-assembled is not always what reviews describe. A head that claims spikes and cores together is only as good as the welds. A scarifier blade is not a corer.
On clay or a lawn that waterlogs, the RHS prefers hollow tines. You pull a plug, sweep it up, then top-dress. Their mix is three parts sandy loam, six parts horticultural sharp sand, not builders' sand, and one part well-rotted compost, about 2–3 kg per square metre. On clay they suggest that work every three to four years. Solid spikes are the ordinary fork method. They suit a lighter seasonal prick and can press clay sideways instead of opening it. Shoes and rollers are solid tines.
Hand tools suit a small lawn or the worn paths. A step plate needs your weight, and reviews on several plates say a bad back or dry summer ground makes the job hard. Shoes are awkward to balance in. Thrive says they are generally felt to be hard to balance on and not very effective, and the shoe reviews add boots, blisters and feet that stick until you lift them. A large area is hire or a contractor.
Three typical situations, each with a recommendation from this comparison.
You have a small lawn or a worn path, and solid holes are enough. A step plate uses your weight. The Walensee 15-spike step plate is the widely reviewed solid-spike plate in this set, about £35.99, and it does not pull a plug.
Water sits on the lawn, or the soil is clay, and you can finish the area by hand. The Dolibest 4-prong corer is the dedicated hollow-tine tool in this set, about £44.99. Sweep the plugs up and top-dress. Clear the tubes if they clog.
You want a solid-spike step plate and the lower of the two tied scores. The Colwelt 4-spike plate is about £26.56, with four spikes listed at 9 cm. The listing itself says this style suits lawns that are not badly compacted.
The top pick is the Walensee 15-spike step plate, score 82, about £35.99, 4.4 from 2,778 amazon.co.uk reviews. The Colwelt also scores 82. The tie breaks to the larger review count. The Walensee is a solid-spike plate, not a hollow-tine result. The best value is the Colwelt 4-spike plate, about £26.56, 4.6 from 535 reviews, the cheaper of the two tied scores. A 4.6 from 9 reviews is not the best value. Neither score is a lawn trial. On clay that needs plugs removed, the Dolibest is the hollow-tine row in this set, and only if the tubes stay clear.
Colwelt 4-spike plate
The same score of 82, at about £26.56, from 4.6 and 535 reviews. It is the cheaper of the two tied scores.
