#1. BLACK+DECKER 3-in-1 Lawn Mower – Best for Compact and Light Design

BLACK+DECKER Cordless Lawn Mower, String Trimmer, Edger, 3-in-1 (MTC220)  “Performs well in hard situations. I never had any issues with it after the first time I used it.”  Specifications Brand: BLACK+DECKER Item Weight: 9.9 Pounds Power Source: Battery Powered Dimensions: ‎40.5″D x 15.25″W x 7.38″H No products found.

Product Review

I am happy to share my experience with the BLACK+DECKER Cordless Lawn Mower. As someone who cares about the environment, I always look for an eco-friendly option. It reduces the carbon footprint and fits in my pocket. 

Besides, it works well in my mid-sized backyard. I tried this mower after reading some reviews, and I am so glad I did.

Design

First of all, I was impressed with how quickly the device arrived. I was surprised at how lightweight it was. It is so light that it feels like I am vacuuming the yard. 

This feature is a big plus for me. I am not very well and am worried that using a traditional gas-powered mower will be too heavy and difficult. So I appreciate a compact design to move around my yard without problems.

Besides, its ingenious design makes it easier for me to mow the lawn. The handle is easy to use and compact enough that I do not need to push it like the heavier gas-powered ones. 

The only downside is that I must keep pressing. As a result, I get tired, but it is not a deal breaker.

Performance

The 20V battery power supply is more than enough for my outdoor needs. In my opinion, it deserves a 5-star rating without any doubt. I like that this machine has two batteries included and lasts about 20 minutes. 

But I would be cautious when using this machine on wet grass. While this is a well-built machine, wet grass will make mowing more difficult.

Moving on to the specifics of my yard size, I measured different areas to let everyone know how much space it covers. I have not cleaned the backyard since my gas mower died. My backyard is 25ft x 10ft, and if I did just this area, the battery would be enough for me to mow the tall grasses I have.

Ease Of Use And Maintenance

In just a few minutes, I had it up and running. It has an automatic feeder system, so I do not need to keep charging after turning it off. It will automatically recharge itself. 

But sometimes, it can get stuck or throw too many lines. Hence, I had to stop and fix it. To do this, take the feeder cover and move it while pulling it out a little counterclockwise.

Although the unit is powerful enough to handle tall grass, I need to move it back and forth, like a gas-powered lawn mower. 

This note is important because it may overheat when you move it quickly. Then you can damage your device. So, just like vacuuming your home, you must take steps to make your life easy.

I used gloves or a brush to ensure proper trimming and prevent the unit from overheating. They are for removing grass that accumulates on the bottom of the machine, similar to the gas-powered ones. 

Therefore, I advise you to do the same. This tip will help keep your tools running smoothly and efficiently. It is important to periodically stop and clean the grass under the trimmer for optimal performance.

Another advantage of this device is that it is perfect for women or anyone who does not want to touch the mower, the elderly, or those with weak physical conditions.

Pros

• Easy to move
• Easy to use
• Compact and light design
• 20V battery power is enough for the use
• Have an automatic recharging system

Cons

• Press the button continuously.

#2. Honda Versamow System Lawn Mower – Best for Performance

Honda HRX217K5VKA Versamow System Lawn Mower “I am happy to use and maintain it easily.”  Specifications Brand: Honda Item Weight: 108 Pounds Power Source: Gasoline-powered Dimensions: 18 x 15 x 8 inches No products found.

Product Review

With this high-performance lawn mower, mowing becomes easier for me. Now find out the reason why I like it.

Design

As a user of the Honda Versamow System Lawn Mower, I have to say that the design of this machine is good. 

Nexite cutting deck and rubber wheels certainly bring a modern look. That style makes it different from other models. I appreciate the attention to the design details for the quality of the final product.

It has a durable Nexite compound promising a lifetime lawn mower warranty. It is a plus for me. I do not have to worry about rust or corrosion, which is often a problem for other lawns.

The steering wheel is comfortable to keep. The thumb control system is a great addition. It is easy to control the drive system that changes with my thumb. 

Also, the thumb control is in the center of the steering wheel. So it is easy to access.

Performance

I used the Honda Versamow System Lawn Mower for a while and was surprised by how it works well. The micro-cut system is simply unbelievable. It provides a sharp and smooth finish for my splendor. 

Moreover, the double-blade grooves are smooth. So I can pile the grass in the oversized 2.5-Bushel pocket without stopping to empty it. Besides, I feel easy to adjust the amount of grass I want to leave and eliminate.

Besides, the drive selection feature is also impressive. I can set the journey to my desired speed. After that, I used heavy pliers to get the ideal cut, even in irregular terrain. I think it may change, but putting everything together is easy.

A disadvantage is that the extra discharge regime does not throw grass as I want. But in general, Honda Versamow System Lawn Mower has exceeded my expectations for performance.

Ease Of Use And Maintenance

I am happy to use and maintain it easily. The drive control button on the steering wheel helped me navigate the lawn mower. I also tried on rough and uneven terrain. 9-inch big wheels and rear wheels make it easier for men. 

Besides, I appreciate how it reduces my muscles while instructing them in the right direction. Also, the speed regulator has a knob that allows me to adjust the cutting speed according to the speed and hardness of the grass. I love a maximum speed of 4 miles per hour, and it is perfect for my law.

Besides, the powerful Honda GCV engine has never failed me. The automatic transmission ensures that it starts with one or two, even after a long rest. 

I appreciate that the maintenance protocol is simple to follow. So I do not have to care about complex maintenance processes.

The only problem I encountered was adjusting the height of the platform, which could be a bit disappointing. But the adjustment accuracy is good, and I understand that a single lever will not provide this accuracy.

Pros

• Durable
• High performance
• User-friendly design
• Easy use and maintenance

Cons

• Slightly challenging to adjust the height

#3. Greenworks 2-in-1 Cordless Push Lawn Mower – Best for Thick Grass with Different Heights

Greenworks 40V 20-Inch Cordless (2-In-1) Push Lawn Mower 25302  “In general, I believe that this lawn mower is really well worth the money.”  Specifications Brand: Greenworks Item Weight: 42.5 Pounds Power Source: Battery Powered Dimensions: 7.13 x 4 x 3.75 inches No products found.

Product Review

I like battery-powered lawn mowers. It helps me to fulfill the role of an environmental guard. It was wise when I chose this Greenworks lawn mower.

Design

First, the foam covering the handle is a beautiful highlight. It helps reduce all vibrations and makes it comfortable when pushing the mower around, even when the safety guarantee is involved.

But I am concerned with the foam coating because it is very thick and can wear or tear. But it is better if it has firm material for living longer.

Another thing to note is that I cannot adjust the handle height. So it may feel a bit shorter for taller people or too high for people shorter. But I think this lawn mower is very similar to traditional gas-cutting machines. 

Besides, it is relatively light (42.5 lbs) and very mobile. It also has larger wheels at the back and seven wheels in the front.

Performance

With separate cutting blades rotating inward, this cutting machine can create an excellent layer. Besides, it offers a clean cut on the entire 20-inch cutting floor. 

I found that the blade had a particularly effective coating and cut the lawn into pieces with no debris. Even in longer grass, the cut is even and smooth. 

Large grass bags, with a capacity of 55L, are mounted behind and have mesh surfaces, peaks, and semi-hard bottoms. I appreciate the small flap on the head up when the bag is full. I can see when it is time to empty it. 

Also, the Viking smart cutting technology ensures that the power or running time is adjusted based on the thickness of your grass. 

In my experience, this technology works well on thick grass with different heights. I also appreciate the automatic battery conversion feature. It ensures that the energy is from one battery at a time and the battery is easily installed and removed.

Ease Of Use And Maintenance

I want to emphasize that I could assemble it quickly and easily. Adjusting the handle from the storage/transportation position to the cutting position is easy. 

I need to loosen a lever, move the handle into place and then flip the lever to the closed position. Besides, I can easily fold the handle to store it more compactly.

When it comes to maintenance, this lawn mower is easy to maintain. I appreciate that I do not have to worry about changing oil, spark plugs, or air filters like gas-cutting machines. 

The battery is easy to remove and charge, and the cutting machine has a battery charger for the battery quickly for about 1 to 1.5 hours, depending on AH. 

I also appreciate the battery status on each battery, showing the remaining charging level.

Pros

• Large grass bag
• Quick assembly
• Beautiful design
• Cut the lawn clean without debris 
• Viking smart cutting technology

Cons

• Foam coating is not durable.

#4. Worx Nitro Cordless Self-Propelled Lawn Mower – Best for Long Battery-life

Worx Nitro 80V 21″ Cordless Self-Propelled Lawn Mower (WG761)  “I’m definitely pleased with the mower after 3 months of use.”  Specifications Brand: WORX Item Weight: 83.78 Pounds Power Source: Battery Powered Dimensions: 40.55 x 21.85 x 17.13 inches No products found.

Product Review

As a fan of battery-powered tools, I am particularly interested in testing this lawn mower. After using it for a while, I can say it is worth investing in.

Design

The first thing that impressed me about the wireless lawn mower was how light it was. This feature makes it extremely easy to control my yard. Although the lawn mower is not self-propelled, its lightness makes up for it.

Performance

This wireless lawn mower is also quite powerful. I could use it to cut some high grasses in my ditch, and it worked as well as my petrol-cutting machine. In fact, in some cases, it works even better. 

Besides, the battery is longer than expected, and I did not experience any energy loss during the cutting process.

Specifically, the mower can run for about 45 minutes to an hour. I recommend investing in additional batteries if you have a medium or larger yard. 

I have not had to do this because my yard is small. But it is good to know that this option is available.

Besides, I appreciate its ecological mode. When I use it in this mode, I can receive four or five cuts from back grass before charging the battery. 

It means I only have to charge the battery once a month or six weeks, which is very good for me. 

When I had to use the Turbo mode, it pulled out in one cut, but it was not a problem because I often used the ecological one.

Ease Of Use And Maintenance

This wireless lawn mower is also very easy to use and store. It took me only a few minutes to operate it. The folding handle is the size of the mower, allowing me to put it on the bottom shelf of the storage unit. 

Besides, I do not need to rely on the inside of the garage as I did with my old one. Although it is not a pain when loosening or tightening four bolts each time using, ensure the cable in the handle is not caught or trapped.

Pros

• Lightweight
• Strong
• Long battery life
• Easy to use and storage

Cons

• The foam rubber covering the handle is not durable.

Summary

With the help of the best mower for thick grass list, you can make the best choice. It’s important to remember to choose user-friendly ones with powerful features because they can increase performance and reduce risks.

I recommend trying the Craftsman Gas-Powered Push Lawn Mower because it is at the top of this list. I guarantee that it will give you a great experience. For the best price, add to your cart instantly! 

Buying Guide For The Best Mower For Thick Grass 

Buying Guide For The Best Mower For Thick Grass

Before going into the in-depth review, I want to mention the criteria for choosing the best thick lawn mower.

Engine Power

When choosing a lawn mower for thick grass, engine power is an essential factor to consider. A powerful engine ensures the cutting machine can handle all grass conditions. 

We use horsepower (HP) to measure the engine power. Besides, it usually ranges from 2 to 7 horsepower for gas-cutting machines. The greater the HP, the stronger the engine. 

When choosing engine energy, it is critical to consider the lawn size and the thickness of the grass. A higher horsepower mower will be a better option for large lawns with dense grass. 

But for smaller ones, a lower horsepower may be enough. Besides, consider the lawn terrain because a hill or uneven grass can need a strong engine.

Blade Type

When buying cutting thick grass, you must consider the type of blade. The standard blade type can ensure cleaner and improve the health of your lawn.

First, consider its shape. An advanced angle blade can produce more attraction. It allows it to lift the grass to cut cleaner. Besides, a curved blade can also help attract airflow. This feature can help easily cut through thick grass.

Second, review blade materials. The steel blade is durable and can handle hard grass. On the other hand, the titanium or carbide blades can last longer and keep sharper, but they may be more expensive.

Third, consider the blade width. A wider blade can cover the ground more with each passing. So it makes the cutting process faster. However, a narrow blade can provide more accuracy and help navigate the obstacles more easily.

Deck Size

The wider deck size means the mower can cover more space with each passing time. I find this feature may be beneficial when treating thick grass.

A larger deck size is usually better for large lawns. It can help you save time and effort by covering more ground with each passing time. 

But a smaller size may be more realistic for smaller lawns. So you can control it around obstacles such as trees or flower beds.

Height Adjustment

Height Adjustment

Before buying a lawn mower, you should research its height adjustment. There should be a min and max value for the clipping height range. 

It is better to choose a high-quality machine with an appropriate adjustment of at least 2 cm and no more than 7-8. With this feature, you can smooth the surface and remove nodules and other imperfections.

Besides, pay attention to the number of fixed positions of the mower. More expensive devices have 5-7 slots each. Meanwhile, the cheaper versions only have 3. Also, this feature makes the work much simpler and expands the range of possible haircuts.

I see both manual and mechanical adjustments. You must physically adjust the altitude in the first case. Meanwhile, you will not need to make any physical effort in the second case.

Self-Propelled Feature

Mowing the lawn becomes more enjoyable with self-propelled lawn mowers. You no longer feel strenuous when pushing the lawn mower uphill.

They come in battery-powered and gas-powered varieties. Besides, they work like any battery or gas-powered lawn mower. The mower pushes itself forward rather than being pulled from the rear by the operator. 

Yet, letting go of both handles will bring the mower and drive to a halt if you need to stop the mower immediately.

Bagging And Mulching Options

I never want to look back and see a pile of hay lying on my freshly cut lawn. I think you do, too. We are all so tired after trying our best to mow the lawn. 

With bagging and mulching options, you will not worry about this anymore. Your yard won’t look cluttered if you pack your grass clippings. 

Thus, it gives your grass a glossy appearance. Using a mower with these accessories makes it easy to maintain a grass-free yard.

Durability

Consider the easy-to-change oil filter before buying a lawn mower. This feature will decide if your machine is durable or not. Your lawn mower can last long if you know how to tune this part.

Consider what parameters the manufacturer provides. Some manufacturers use hours of use to calculate the life of their lawn mowers and components. 

For example, more expensive lawn mowers often last 500 hours or more. Meanwhile, some cheaper machines can only last 200 hours or less. So the frequency and duration of use can affect the life span.

User-Friendliness

You can find convenience in an easy-to-use lawn mower. To do this, look for lawn mowers with a simple starting system. 

You can decide between an electronic and tow rope starter with a little effort. You may find it simpler to start the machine with this function.

Besides, choose a lawn mower with simple controls. Consider machines with separate labels. With this feature, you can understand it easily. Also, choose a machine that is just right in size and corresponds to the size of your lawn. 

Finally, consider lawn mowers that are easy to disassemble for replacement parts. You can also easily clean it with this feature.

FAQs

What Is A Good Heavy-Duty Lawn Mower?

A heavy-duty lawn mower is one designed to handle many mowing jobs. It can cut thick grass, weeds, and even small trees. In other words, it is a sturdy mower. You can use it continuously and can handle rough terrain with ease. 

Besides, the heavy-duty lawn mower must have a high-power motor and large cutting width.

Some of the key features to look for in a heavy-duty lawn mower include:

• Big engine power
• The type of blade that can handle tough mowing jobs
• Large deck size
• Reliability

How Many Hours Should The Mower Last?

According to my survey, most lawn mowers only last an average of 500–700 hours. Meanwhile, some lawn mowers can last up to 1,000 hours with proper care and maintenance.

Specifically, the useful life of most circuit breakers is from 6 to 10 years if the breaker operates 2 hours/week. But a few things affect how long your machine is in front.

First, your lawn mower will run less time than if you were mowing on uneven territory. The same thing happens if you use it on mountainous terrain. 

In these cases, it is subject to more pressure. If you must go through this terrain type, proceed carefully and avoid sharp turns.

Second, the longer your lawn mower is used, the shorter its lifespan.

Third, lawn mowers may not last long if you don’t perform regular maintenance and repairs. Thus, be careful to do oil and filter changes periodically. 

Besides, sharpen the blade at least twice and test for wear and tension on all belts, cables, and hoses. Also, remember to clean the machine regularly!

Are Electric Mowers Good For Thick Grass?

Yes, electric mowers can be good for thick grass. But it depends on the model and its capacity. Some electric mowers have enough power to handle thick grass. Meanwhile, other machines may have difficulty. 

Choose a circuit breaker with a high power rating, preferably over ten amps, and a blade with a sharp cutting edge. 

Besides, cordless electric mowers with lithium-ion batteries are the best choice for thick grass. They tend to have more power and longer battery life.

Which Brand Of Lawn Mower Is The Most Reliable?

It is difficult to say which brand is the most reliable. Each brand has its strengths and weaknesses.

I know Honda has high-quality engines and performance. As a result, they have become a popular choice among lawn care professionals. Their lawn mowers are also renowned for being easy to start and maintain.

Great States is another trusted brand with a wide range of mowers for different types of grasses. They are known for producing mowers that are both durable and easy to use.

Worx Nitro is a trusted brand that has been around for years. They are known for their high-quality construction and powerful engines. So they are popular with people with large lawns or commercial properties.

Why Does My Lawn Mower Keep Dying In Thick Grass?

If this problem occurs, it may be due to a damaged spark plug. Although making up a small part of a lawn mower, spark plugs affect how well the machine runs. 

Thus, check the spark plugs if your lawn mower frequently stalls or stalls while mowing.

For this maneuver, look for signs of wear and tear. Electrode failure or burnt electrodes can be indicated by something as basic as a cracked insulator. Then replace them if you also notice a lot of carbon build-up.

I recommend using a spark plug tester if you have one lying around in your workshop. Check if it’s broken or still working. 

A spark between the poles indicates that everything is working. If the flash is not visible, the spark plug is damaged.

What Type Of Mower Provides The Cleanest Cuts?

Reel lawn mowers provide the cleanest cuts compared to other mowers. They use the scissor action to cut the grass clean and evenly, leaving a sleek look. Reel lawn mowers have a series of curved blades that rotate on a fixed rod. 

Hence, they produce a mowing action to cut the grass. This feature contrasts with a rotary mower, which uses a single blade that rotates horizontally and cuts off the top of grass.

Another type that can help you cut cleanly is the robot mower. These lawn mowers use advanced technology to produce a precise and even cut. 

As a result, they often leave no visible lines or clusters of grass. They use a series of small, rapidly rotating blades. They then create a fine layer of mulch left on the lawn to decompose and provide nutrients.

Which Lawn Mower Is The Most Durable?

The Honda Versamow System is my recommendation when it comes to durability. I have to admit that its design is the best for a user. 

Rubber wheels and a Nexite cut-out floor certainly contribute to the durable look. I appreciate the careful design to ensure the quality of the finished result.

Besides, I also mentioned that it has a Nexite compound for sure. This material contributes to the lawn mower’s lifetime warranty. For me, that’s a bonus. I don’t worry about rust or corrosion.

Is A Bigger Lawn Mower A Better Choice?

No, it is not. A smaller, more maneuverable machine can help you get the job done faster and with better results. 

Commercial and residential lawn spaces rarely have perfectly flat surfaces. In these spaces, you have to navigate sudden tilts and gradients.

In these cases, large lawn mowers become cumbersome. Besides, they have the disadvantage of being able to cause holes and peeling. 

In addition, there will be uneven cuts in drains or basins, even shallow ones. Sometimes the deck of a large breaker doesn’t fit in the lowest part of the drain. 

As a result, you must use smaller mowers and lengthen the time it takes to get the job done.

Should I Get A 42 Or 48-Inch Mower?

In my experience, the 42″ mower is a great place to start for a medium-sized yard. It ranges from an acre to an acre and a half. With this mower, you will take longer to navigate into and around tight bends with larger mowers. 

On the other hand, mowers with 42″ to 48″ cutting floors are the right size for homeowners with a cut area from 1.5 to 3 acres.

How Many CCs Should A Good Lawn Mower Have?

Engine sizes for lawn mowers vary from 140 to 190 cc. For hard-cutting situations, choose a larger motor. I’m referring to tall, wet, bagged, foliated, or continuous grass when you’re weeding,

At present, mower motors have the following types:

• The most basic and affordable is an auxiliary valve.
• Overhead valve motor. It has a valve in the cylinder head like a car engine.
• Direct overhead valve variant. I find this motor to cost more. But in return, you’ll get better fuel economy, lower emissions, less vibration, and quieter mowing.

Is It Worth Buying An Expensive Lawn Mower?

The answer depends on your circumstances and needs. Expensive lawn mowers tend to have more advanced features. They can have larger cutting decks, higher horsepower, and self-propelled options. 

These features can make mowing your lawn faster and easier. They can be valuable if you have a large or complex one.

But, if you have a small lawn, an expensive lawn mower may not be worth the investment. Hence, a more affordable lawn mower may also meet your needs.

What Size Mower Is Best For 2 Acres?

For 2-acre lawns, a lawn mower with a cut floor size of at least 42 inches is the best choice. This size can cover the ground quickly and make mowing less time-consuming. 

But, if the lawn has steep hills or uneven terrain, a smaller deck size may be more appropriate. It can ensure the mower can move in the area safely.

Also, if there are a lot of trees, gardens, or other obstacles on the lawn, a lawn mower with a smaller deck size can make it easier to navigate these obstacles.

How Often Should Lawn Mower Oil Be Changed?

Change the mower at least once a year or every 50 hours of use, whichever comes first.

But, if you use the mower more often, such as for commercial purposes, you may need more frequent oil changes. It is best to consult the manufacturer’s recommendations for your particular model. 

In addition, you should regularly check the oil level before each use and add more if needed.

When changing the oil, follow the manufacturer’s instructions for your particular model. Proper disposal of old oil is also essential because it can harm the environment.

How Can I Make My Lawn Mower Last Longer?

Here are some tips to help you keep your lawn mower in top condition:

• Read the user manual.
• Keep the mower clean.
• Check the oil.
• Sharpen the blade.
• Change air and fuel filters regularly.
• Maintain a lawn mower properly.

How Do I Know If My Lawn Mower Is Broken?

There are several signs that your lawn mower may need repair. Here are some common signs to look out for:

• The machine does not start or continue to run.
• The engine makes strange noises.
• Improper blade.
• The lawn mower vibrates excessively.
• Unusual smoke or smell.

If you notice any of these or other unusual behavior with your lawn mower, it’s best to stop using it immediately. Then consult a professional for repair.

What Can Damage A Lawn Mower and Weed Wacker?

Some factors can damage a lawn mower and affect its performance, including:

• Too hot
• Lack of maintenance
• Rough terrain
• Improper use
• Old age

To avoid damage to the lawn mower, follow the manufacturer’s instructions for use and maintenance.
