⭐ Reviews – Best Mowers For Wet Grass of 2024
In our opinion, the best overall lawn mower for effectively mowing wet grass is the Hyundai 17″/43cm 139cc Self-Propelled Petrol Lawnmower.
This mid-sized lawn mower boasts features that make it safe and easy to cut wet grass, including efficient grass collection, a powerful 139cc engine, self-propulsion, and a durable alloy steel and plastic corrosion-resistant build.

Weight: 28 kilograms
Grass box capacity: 45 litres
Dimensions (DxWxH): 53.2cm x 19.3cm x 41.3cm
Engine power: 139cc
Best For:
Anyone who wants to invest in the best-value petrol mower that reliably and efficiently mows wet grass without clogging or lawn damage.
What Customers Think:
The Hyundai 139cc Self-Propelled Petrol Lawnmower is a popular choice with customers on Amazon – it has a 4.4-star rating out of 5 (at the time of writing) from more than 800 reviews. We looked specifically for reviews that mentioned mowing wet grass, and all customers praised the mower on this front. One customer said that they’d used the mower on very long, wet grass with no clogging, and another reviewer said that mowing grass with morning dew means “nothing to this machine”.
Pros:
There are a few design features that make the Hyundai 139cc Self-Propelled Petrol Lawnmower ideal for mowing wet grass: it has a good grass flow into the collection bag even with wet grass, and its powerful 139cc engine can handle the additional resistance of mowing a wet lawn. Even better – the mower has self-propulsion, so you don’t have to put in the extra effort of manually pushing it over wet grass.
The rear wheels are slightly larger than the front wheels (17cm vs 15cm), giving you more control and better maneuverability on slippery ground. The wheels have tyre grips, too, preventing you from skidding on a wet lawn.
You can adjust the cutting height right up to 75mm – ideal if you’re cutting wet, long grass and want to reduce the risk of clogging beneath the mower deck.
It’s good to see multiple grass cutting options, including side and rear discharge, so you can discharge the grass back onto your lawn and rake it up after if you don’t want the hassle of cleaning out a damp grass collector.
Cons:
The assembly instructions are unclear.
We’ve read reports of the wheel trims flying off mid-mow.
If you’re looking for a lightweight lawn mower that’s less likely to leave wheel tracks or slip and slide over a wet lawn, we think you can’t go wrong with the Murray EQ2-300 Petrol Lawn Mower.
This mower weighs just under 24 kilograms – impressive given its powerful 125cc Briggs and Stratton 300E Series engine, its large wheels with good grip on all terrain, its 42cm cutting width and roomy grass collection box, and its solid, durable, rust-resistant alloy steel build.
Quick Specs:
Brand: Murray
Price: ££
Power source: Petrol
Cutting width: 42cm
Cut height range: 25-75mm
Weight: 23.88 kilograms
Grass box capacity: 45 litres
Dimensions (DxWxH):96cm x 38cm x 101cm
Engine power: 125cc
Best For:
Folks who want a lightweight push mower that makes easy work of cutting damp grass and is light enough to easily manoeuvre and steer on slippery ground.
What Customers Think:
The Murray EQ2-300 Petrol Lawn Mower is another popular lawn mower, with 4.3 stars from more than 700 customer reviews. Again, we looked for reviews from customers who had used this mower on wet or damp grass, and all reviews we could find were positive. One customer said that the engine starts on the first pull and cuts grass well – even when the grass is damp. Other customers agreed that the mower could be used on wet grass, calling it a “reliable mower” that “feels like it’s well-made”.
Pros:
We think the big selling point of the Murray EQ2-300 for mowing wet grass is that it’s lightweight at just 23.88 kilograms. The mower is lighter than most other mowers on this list because it doesn’t have the extra weight of a self-propulsion function, which means it’s easier to turn and push, and less likely to leave rut marks on your lawn.
The 75mm maximum cut height allows for plenty of under-deck room and helps prevent clogging of the blades if you need to mow long and wet grass.
You’ll fit plenty of grass clippings in the roomy 45-litre grass bag, which means faster mowing with fewer interruptions. If you’d rather not make the inside of the bag damp, you can always switch to rear discharge and rake up the grass clippings after.
Both wheels are a decent size at 18cm, and they’ve got good grips to prevent skidding when mowing on slight inclines in wet conditions.
Cons:
The instructions manual is poor.
This mower isn’t the best for edge cutting. You’ll probably need to finish off with a trimmer.
Our top recommended lawn mower with the best design for cutting wet grass is the Webb WER410SP 16”/41cm Self Propelled Rotary Petrol Lawnmower.
If we were designing a dream mower for wet grass, it would have many of the design features of this Webb mower: the self-propulsion, the powerful 132cc 4-stroke engine, the choice between grass collection and discharge, and the durable alloy steel build. It’s not too expensive either, costing around £250 (at the time of writing this review).
Quick Specs:
Brand: Webb
Price: ££
Power source: Petrol
Cutting width: 41cm
Cut height range: 25-75mm
Weight: 26 kilograms
Grass box capacity: 45 litres
Dimensions (DxWxH): 72cm x 52cm x 43cm
Engine power: 132cc
Best For:
People who want a petrol lawn mower with all the design features to capably mow wet grass and dry grass with equal efficiency.
What Customers Think:
More than 550 customers have reviewed the Webb WER410SP mower, awarding it a 4.4-star average rating out of 5. Customers said that the mower was quick and easy to use regardless of whether the grass was wet or dry, and didn’t clog or stall when mowing in damp conditions. Reviewers also praised the mower for being easy to start and assemble.
Pros:
In our opinion, the Webb WER410SP petrol lawn mower is ideally designed to mow wet grass, offering a good balance between power, weight, and manoeuvrability. It weighs just 26 kilograms despite the extra weight of its self-propulsion, so you can efficiently mow a damp lawn without the resistance of manual pushing and a reduced risk of damaging your lawn with wheel tracks.
If you prefer to collect your grass clippings, you’ll be happy to hear that the large port into the grass collection bag doesn’t clog easily when collecting wet grass, so you can fill the bag without pausing to deal with a blockage.
The mower’s rear discharge function is also an option if you want to avoid grass bag empties and rake up the damp grass after mowing.
You can adjust the cutting height all the way up to 75mm with the single, easy-use lever, so you can create more space under the mower deck if you’re dealing with wet and long grass.
Webb is a respected British firm that’s known for its lawn mower quality, and the steel deck and cutting blade on the WER410SP are solidly built and should stand the test of time.
Cons:
The 41cm cutting width is on the smaller end, so this mower isn’t ideal for larger lawns.
The grass collector doesn’t have a lower lip, which means a few clippings end up falling out when you pull it away from the mower.
If you have a large lawn and you want a lawn mower that you can use to cut wet or damp grass, we think the Murray EQ2-500 Self-Propelled 46cm Petrol Lawnmower mower can’t be beaten.
This lawn mower has a wide cutting deck (it measures 46cm across) so you’ll be able to cut your lawn in fewer passes. Plus, it has all the features that make it capable of cutting wet or damp grass, including a heavy-duty 140cc self-propulsion engine, large 15-20cm wheels with tyre grips, and a cut height range of 25-75mm.

Weight: 26.56 kilograms
Grass box capacity: 50 litres
Dimensions (DxWxH): 96cm x 38cm x 101cm
Engine power: 140cc
Best For:
Anyone looking for one of the best lawn mowers for wet grass with a wider cutting deck for efficiently cutting larger gardens.
What Customers Think:
The Murray EQ2-500 has a 4.3-star average rating from just over 700 customer reviews. Reviewers were pleased with the mower’s ability to cut wet and long grass, with one customer saying it made easy work of mowing the edges of an overgrown field, and another saying that it cuts through damp grass well. Customers also agreed that setup was quick and simple and praised the mower’s foldable handle for easy storage.
Pros:
With its 46cm cutting width and 26.5-kilogram build, the Murray EQ2-500 makes fast work of mowing large lawns without too much weight or bulk, helping to keep steering and manoeuvrability easy on wet surfaces.
It’s good to have the option to collect grass cuttings in the roomy 50cm grass collection bag, but you can also discharge them on your lawn and rake them up after to avoid the hassle of clearing wet grass out of the collection bag. There’s also a mulching plug for when you’re mowing dry lawns.
The EQ2-500 is another petrol mower that has been thoughtfully designed with durability in mind. The steel deck is solidly built and resistant to damage and corrosion, even if you occasionally use the lawn mower for wet grass.
Plus, the integrated wash port (a unique feature that you won’t find on all mowers) allows you to attach a garden hose to the mower’s deck, making it easy to clean after cutting wet grass.
Cons:
The self-propulsion is set at one speed, which might be too fast for some people – especially when you’re mowing wet grass and need to watch your footing on a slippery surface.
It’s not the fastest cold-starting mower we’ve reviewed (it usually takes around two or three pulls).
You don’t have to spend a fortune on a petrol mower for cutting wet grass, as proven by the Mountfield HP41 Petrol Lawnmower.
This hand-propelled petrol mower costs around £180 (at the time of reviewing) – a great price for a 39cm lawn mower with a 123cc STIGA ST120 Autochoke engine. Despite its lower cost, the mower still has most of the features that you need to easily mow wet grass, including adjustable cutting heights up to 70mm, a lightweight 19-kilogram design, and grooved wheels for good traction.

Engine power: 123cc
Best For:
Folks who want to spend less upfront on a budget-friendly lawn mower for wet grass, without having to compromise on design quality or performance.
What Customers Think:
Of the 500+ customers who reviewed the Mountfield HP41 Petrol Lawnmower, the majority had only positive things to say, awarding the mower a 4.6-star rating overall. We read a review from a customer who said that the mower made cutting damp grass much easier than an electric mower. Customers also agreed that the mower is easy to assemble, starts with no issues, and is easy to push and steer.
Pros:
The obvious advantage of the Mountfield HP41 mower is its affordable upfront price. You can spend less than £200 on a mid-sized lawn mower that’s solidly built and powerful enough to effectively mow long and wet grass time and time again.
This Mountfield model is super lightweight at just 19kg, so you should be able to stay in full control of the machine even when you’re mowing uneven lawns with wet or damp grass.
You can adjust the cut height to suit your mowing conditions, with a max. cut height of 70mm for cutting wet and long grass. The cutting height system is easy to use, too – just press the levers over each wheel.
Cons:
The engine isn’t quite as powerful as other petrol mower engines. While this helps to reduce the mower’s weight, it might struggle in certain grass cutting scenarios (such as cutting very long grass).
It doesn’t look like there’s a side or rear discharge option, which means you only have one grass collection option: the grass bag.
☔️ Should You Mow The Lawn When It’s Wet?
Ideally, you shouldn’t mow the lawn when it’s wet.
Wet grass blades are heavier and bow towards the ground, which means you won’t achieve an even cut as you would if all the grass blades were upright. Plus, wet grass clumps together, clogging your mower blades. This can also result in an uneven cut as some areas may be missed or cut shorter than others.
Pushing a mower over wet soil may also result in long-lasting damage to your lawn. The mower is more likely to sink and leave wheel ruts in wet soil than it would in dry, solid soil.
You especially should never mow wet grass with an electric mower. When you use an electric mower on wet grass, there’s a real risk that the water will conduct the electricity. Most lawn mowers have metal handles, so a spark in the mower’s system could send a shock through your hands and into your body.
However, sometimes, you may have to cut wet grass. You may cut grass for a living, and you simply can’t wait for the absence of rain on the ground to get the job done. Or, your only convenient time to mow might be on a rainy weekend.
In this case, we recommend looking at petrol lawn mowers, which are the safest and best lawn mowers for wet grass.

🧾 8 Features Of The Best Lawn Mowers For Wet Grass
Wondering which lawn mower features will make it easier to mow wet grass? We’ve shared our top recommended features to look out for below.
📦 Effective Grass Collection
Some lawn mowers struggle to collect grass effectively when it’s wet.
If you plan to occasionally or regularly mow damp grass, you need a mower that can still effectively fill the grass collection bag or box in this scenario.
Look for a mower with a good grass flow into the collector (even when the grass is damp). The wider the opening into the grass collector, the less likely it is to clog due to clumps of wet grass.
You probably won’t find a lot of information about a mower’s grass flow/collection abilities in the manufacturer’s marketing materials, but this is something that customers are likely to talk about in their reviews.
↘️ Side/Rear Discharge
We personally think that the best thing to do with wet grass is to discharge it back onto your lawn and rake or sweep it up after, rather than trying to get clumps of wet grass out of your grass collector.
In this case, you need a lawn mower with a side or rear discharge function. All the best lawn mower models on this list have this function.
A mower with side or rear discharge cuts grass as normal, then shoots the clippings out of the side or rear of the machine. This saves you the hassle of having to clean out your grass collection box, which will be more difficult if it has been used to collect wet or damp grass.
🏋🏻 Lightweight Design
Also prioritize lawn mowers that are lightweight and easier to manoeuvre on wet soil, with a reduced likelihood of sinking into the soil and leaving wheel marks.
Ideally, look for a push petrol mower with a 20-22-kilogram weight range, or a self-propelled petrol lawnmower with a 26-28-kilogram weight range, max.
A lightweight mower will be easier to steer and control on a wet, slippery surface, helping you to mow more efficiently and reducing your risk of injury.
⚡️ Non-Electric Power
As we mentioned earlier, mowing wet grass with an electric lawn mower is not recommended.
Both corded and cordless electric mowers are not an option for even damp grass. The risk of an electric shock simply isn’t worth the reward of a tidy lawn.
Petrol lawn mowers are the only mowers we recommend for cutting grass that’s wet. They don’t use electricity, so, importantly, they’re safe to use in damp conditions.
Plus, petrol mowers are more powerful than electric mowers and are more capable of cutting grass in challenging conditions. They’re also a good option if you have longer or thicker grass that needs cutting.
✂️ Sharp Blades
Sharp, durable blades are an essential feature of the best lawn mower for wet grass.
It goes without saying that you should choose a mower with steel blades, rather than plastic. Steel blades are much more durable and capable of mowing damp, long, or rough grass, and most petrol mowers come with steel blades as a given.
It’s your job to sharpen your lawnmower blades once or twice per mowing season to maintain your mower’s grass-cutting ability. Sharp blades provide a neat, clean cut, while dull, blunt blades are more likely to tear the ends of grass.
Before mowing a damp lawn, quickly sharpen your mower blades to allow them to quickly cut through wet, thick grass.
⚪️ Larger Rear Wheels
The best lawn mower for damp grass should have large wheels – and ideally, the rear wheels should be slightly larger than the front wheels.
This allows you to have more control over the mower when pushing it from behind because the mower is weightier at the rear.
Wider wheels also spread the mower’s weight over a larger surface area, reducing your likelihood of sinking into the soil.
On the subject of wheels, also look for a mower that has grooved wheels, which will give it better traction on slippery wet ground, reducing your risk of injury.
📏 Adjustable Cutting Deck
Opt for a mower with a deck specifically designed for cutting wet grass.
Look for mowers with a high-clearance deck, which allows for better airflow and prevents clogging. Ideally, the mower’s maximum deck height should be at least 70-75mm. Some of the best lawn mower models allow you to adjust the cutting height to 90mm or higher.
Wet grass tends to be taller and is prone to clumping together, so having the ability to raise the cutting height allows you to avoid excessive strain on the mower and achieve cleaner cuts.
🦾 Durability And Corrosion Resistance
Finally, look for a lawn mower with a solid, durable design that can withstand cutting grass that’s wet.
Wet conditions can accelerate rust and corrosion. Choose a lawn mower made of durable materials that are resistant to rust and corrosion, such as stainless steel. Or, if your budget is smaller, look for a mower made from heavy-duty plastic, or a mower with corrosion-resistant coatings.
No lawn mower is 100% corrosion-resistant, which is why you should only mow wet grass on rare occasions.
📝 6 Things To Consider When Choosing The Best Lawn Mower For Wet Grass
Aside from looking out for the best mower features for wet grass, also consider the following things when deciding on a mower for mowing a wet lawn:
💰 Your Budget
Start by considering how much you can afford to spend on a new lawn mower.
If you specifically want a mower that can be used on damp grass, you’re looking at petrol lawn mowers. These mowers are more expensive than electric or cordless lawn mowers – the average cost of a petrol lawnmower is £200-£400.
On the lower end of the price scale are petrol push mowers. These cost £170-£300 on average.
Petrol self-propelled mower models are more expensive because of their extra self-propulsion feature, which drives the mower forward without you having to push it. They cost £225-£400 on average.
While petrol mowers are more expensive than other mowers, they’re also more powerful and durable, so you can enjoy a better performance quality.
🟩🟢 Your Lawn Size
Also consider your lawn size, and your ideal mower cutting width.
For medium-sized lawns, a deck width of 30-36cm is optimal. This will allow for cutting grass efficiently while still giving you a relatively tight turning circle and allowing you to easily manoeuvre the mower around obstacles and corners.
If you have a large lawn, opt for a lawn mower with a 36-43cm deck width. This will allow you to cover more ground with every pass, so you can get the job done faster and with fewer laps of your lawn.
The bigger the mower, the higher the price tag. There’s no need to size up for the sake of it – you could end up inconveniencing yourself if you don’t have the garden space to manoeuvre a bulkier mower.
Note: We don’t generally recommend buying a petrol lawnmower for a small lawn because electric mowers are often more convenient for smaller spaces, requiring less setup and maintenance.
🛠 Assembly & Maintenance
Your assembly and maintenance preferences are also worth considering before you spend your money on a lawn mower for wet grass.
Even the best petrol mowers are often more difficult to assemble and require more maintenance than electric or battery mowers.
Some of the maintenance jobs required for a petrol lawnmower are:
Changing/topping up the petrol
Changing/topping up the engine oil
Cleaning the mower after every use
Sharpening the mower blades
Cleaning/replacing the air filters whenever necessary
Cleaning/replacing the spark plug whenever necessary
Lubricating the parts
Make sure you’re prepared for the commitment of owning a mower with a petrol engine. It’s worth deciding whether the benefits of this mower type – including its ability to cut wet and longer grass – makes it worth the extra responsibility of ongoing maintenance.
🎧 Noise & Emissions
Petrol lawnmowers are noisier than other mower types because of their petrol-powered engines. The manufacturer of your chosen mower will probably recommend that you wear protective ear coverings when using the mower, so make sure to follow the safety instructions in your user manual carefully.
These mowers also release emissions, again due to their petrol engines. An EPA study found that around 26 million tonnes of pollutants were emitted in 2011 from petrol-powered lawn and garden equipment – and that was over 10 years ago, so it’s possible that this number is much higher today.
If noise and emissions are a concern for you, you might want to consider a no-petrol alternative – even if that means you won’t be able to use the mower to safely or effectively mow wet grass.
🏠 Storage
Make sure you have enough available storage space for a lawn mower for damp grass before you spend your money.
Petrol-powered mowers are typically designed for larger spaces – medium lawns or bigger. If your small shed is already crammed full of garden tools and lawn care equipment, you might not have room for a large, bulky, heavy mower with a petrol engine.
Measure your available space and compare your findings to the dimensions of a lawn mower you’re interested in. If space is limited, look for a mower with a foldable handle, which should reduce the amount of floor space it takes up.
💬 Warranty & Customer Feedback
We always recommend buying a lawn mower with a warranty and good customer feedback, regardless of how you plan to use it.
Most of the mowers on this list have a warranty of at least 2 years. A warranty tells you that the manufacturer has full confidence in its product and ensures you of product quality. It also means that your purchase is protected, and you’ll be covered if you receive a mower that’s faulty or broken.
Customer reviews give you insight into a lawn mower’s performance beyond what you can read in the product description.
You can search for specific keywords on Amazon – we did this when determining which customers had a good experience with the mowers on this list, specifically when cutting wet grass.
While it’s normal for a small percentage of reviews to be negative, think twice about buying a lawn mower if a lot of customers are all complaining about the same problem, and if this problem significantly affects the mower’s performance or usability.
