Best Mulching Lawn Mower [Updated [year] ]

Do you love to garden, but you aren’t sure which lawn mower suits your purpose best?

It’s actually quite simple.

For me, gardening started as a hobby but soon turned into an integral part of my life. Now, I can tell you exactly what you need just by looking at your lawn or the way you do your gardening.

So, before you think of buying a lawn mower, ask yourself:

Do you want more power or do you like it the old-fashioned way?

Is your lawn too large for a corded mower, or is it quite small and has many bushes and narrow spaces?

Do you want to go green and opt for a mower that leaves less carbon footprint? Or do you need the power and freedom of a good gas lawn mower?

If you already have a lawn mower, then…

Are you dissatisfied with the cutting length?

Does it lack in any of the features you prefer in a mower, like mulching or bagging the debris?

Are you looking for a more cost-effective and efficient alternative that saves both on time and fuel?

Is your mower a battery-run one and fails to deliver what it had promised?

There are many considerations that you must check out before narrowing down on the right lawn mower.

But, of all the options, if you still want something handier like a walk-behind lawn mower, with different levels of automation and features, take a look at our Top 10 Lawn Mower Models.

With our list of the US’ 10 Best Walk-Behind Lawn Mowers, choosing the right one for your garden or lawn is easy peasy!

This batter-run variant from GreenWorks can offer up to 70 minutes of run time, which is at par with any good electric variant in the market.

Its 46” x 19” x 38” dimension makes it one of the smallest battery powered mowers currently in the market. These features offer convenient maneuverability for anyone who wants to operate it.

On testing its performance, Irealized that this is one durable mower that will last for years with minimal maintenance. So, thumbs up for that!

I’ve noticed that cutting through tall grass and weeds in wet grass is no big deal for this amazing mower. Even if the motor overheats, it still manages to get the work done smoothly. Besides, its small dimension also ensures you bust weeds from even the narrowest of crannies. I would also recommend it those who have small gardens.

It is also designed for people with moderately sized yards, unlike most typical lots.

6 .WORX WG782 14-Inch 24-Volt Cordless Lawn Mower with IntelliCut, Battery and Charger Included

Since IntelliCut technology-powered lawnmowers are gaining popularity in the market, it was only natural that we would feature it in our list, and WORX WG782 14-Inch 24-Volt Cordless Lawn Mower with IntelliCut was our choice in this category.

The IntelliCut technology not only adds more precision, but also an increased range of power to this lawnmower’s motor. So, it is great for hard grass terrains.

Brushless motors are quite the rage in cordless power tools these days. It may make a mower a little pricey, like above $3oo, but it definitely makes it worth it!

This cordless lawnmower comes with a durable 21” steel cutting deck, allowing its owner to Mulch, Bag, or Side Discharge smoothly, and two 2.5 AH (40V)lithium batteries in the original package. However, I would only recommend it to those who have small yards. The original batteries aren’t equipped to handle the demand of medium to larger-seized lawns or gardens. You may have to fetch new ones to make the most out of the machine.

This is one self-propelled mower that I had to try out, since this was the best rated self-propelled mower in the US. This comes equipped with an electric-start button for easy usage.Powered by a 159cc OHV drive-engine, the motor offers sufficient torque to mow even the thickest grass. I found its 21-inch steel deck to be quite durable.

9. Yard Machines 140cc 21-Inch Push Mower

Manufactured by Australian company MTD, this Yard Machines product can be rated as a competitively priced entry-level lawn mower.While it may be quite inexpensive, it packs quite the power.

I liked its neat design. It is lightweight and comfortable to walk around with.

This is, however, not for those of you who want a multi-functional machine.  If you are game for a mower without a catcher bag, you can work with this.

10. American Lawn Mower Company 1204-14 14-Inch 4-Blade Push Reel Lawn Mower

I think this is the second push reel lawnmower that deserves to be on this list. Unlike the GreenWorks 20-Inch mower, this does not have 5, but 4 blades. One of the cheapest lawnmowers in the market, this is also one of the lesser-featured ones.

This is for those of you who are going back to the traditional manual reel lawn mowers, just because of nostalgia, or maybe they want the exercise or simple because their lawns are too small for a full-blown, mega-featured lawnmower.

American Lawn Mower Company 1204-14 can get the job done just as quickly as any high-end mowers, without producing any emissions, and that too at a fraction of the cost you would end up spending on the multi-featured electric, gas or battery-powered land mowers.

How to choose the right lawnmower?

Mowing and mulching your own lawn can be quite an enjoyable experience, but only if you have the right equipment. Here, I have tried to explain the key points you should remember while buying a new lawn mower for your yard or garden.

These are the considerations that I have looked into to choose the above Top 10 list.

Generally speaking, there are three types of lawn mowers available in the market, all of them efficient in cutting grass. The types are:

i) Walk-behind mowers (which is what we are dealing with in this article)

ii) Riding mowers

iii) Tow-behind mowers

The walk-behind mowers are the cheapest category among the three types and their speed depends on your pace of walking. These traditional lawn mowers can again be of 4 different varieties:

  1. Reel mowers, both manual and powered, including self-propelled
  2. Corded electric mowers
  3. Cordless or battery-powered electric mowers
  4. Gas-powered mowers

Most of these types of lawn mowers are the more eco-friendly types. So, let’s find out which type of lawn mower is best suited for you and what you should consider before buying them.

1. Reel mowers:

These mowers use blades that rotate like those of a paddle boat, pulling the grass into the mower so the cutter bar can clip it. This leaves the blades of grass fresh and green. Choosing the right reel mower depends on three basic details:

  • Propulsion System:Here you have two choices: manual reel mower or a powered reel mower. This is the classic variety. It has no engine or motor – it is powered by force of body. While it needs more effort to use, it has some advantages. They are budget-friendly, emits hardly any noise or fumes, requires no fuel, electricity or battery power and no motor to operate. This means it is also a low-maintenance machine.  But if you want a fine cut without the extra effort, there is the option of powered reel mowers.
  • The number of blades:Depending on their blades, reel mowers are again available in three different styles – 4 blades, 5 blades and 7 blades. Your choice will depend on the type of grass you need to mow. For the bent, heavier variety like the Bermuda or StAugustine, get a seven-blade mower. However, for finer, thinner grass variety, such as fescue or Kentucky bluegrass, four-blade and five-blade variants of reel mowers are good enough.
  • The mower’s width: All types of lawn mowers, including the reel ones, come in different widths – from14 to 20 inches. The wider the deck, the wider area you cover, hence faster you will mow your yard. But wider cutting decks also mean heavier machines.
  • Reel Mower Accessories: What add-ons are provided by the model you are thinking to buy? Does it have rear bag to collect the grass? Does it also mulch? These too should be considered while selecting a reel mower.

2. Corded Electric Lawn Mowers:

These are ideal for small yards. They don’t require a lot of maintenance and you get to save money on gas. Since it requires no gas, it is also eco-friendly. The consideration before buying a corded electric lawn mower are:

  • Decksize: Their deck width rangesfrom a 14-inch to a 20-inch cutting path. The wider the cutting path, the fewer trips you’ll need to make to mow your lawn, and the faster your work is done.But, that also means you have to shell out more upfront.
  • Discharge system of grass clippings:You can choose to bag your grass clippings or leave them on the ground. Electric mowers with a 2-in-1 design allows you spread your clippings over your lawn in one of two ways–a side or rear-discharge chute to expellonger grass clippings or a mulching setting to cut clippings extra-fine and leave them below the mower as fertilizer. Some electric mowers that have a 3-in-1 configuration give you a third option; you can bag your clippings to keep your lawn looking neat and tidy. Usually, corded electric mowers are more efficient as mulching mowers, but being able to bag the unwanted debris does seem like an attraction option too.
  • Extension cord length:This completely depends on your individual lawn and its distance from the nearest plug point (which would generally be your garage). If your lawn mower falls short to cover the entire lawn, you may want to buy an extension cord. But make sure the extension cord is no longer than 50 feet, of 12-14-guage thickness and UL listed and CSA certified for outdoor use. Your mower’s user manual will also have additional information on what you should do in such situations.

3. Cordless Lawn Mowers:

Cordless lawn mowers are simply battery-run mowers. The differentiating factors that will determine your choice in this case are:

  • Mower Batteries:The biggest convenience of owning a cordless electric mower is that you don’t need to drag an extension cord around the yard. It provides you with the freedom of gas mowers without the fumes and the need for frequent refueling. Cordless mowers use either lithium-ion batteries or lead-acid batteries. Since, both types can produce a range of power (18 to 120 V), look for the one with the higher voltage, since that will ensure more cut grass. However, the difference between the two is that while lithium-ion batteries store more energy and hold a longer charge than rechargeable lead-acid batteries, lead-acid batteries are more corrosion- resistant.
  • Push or Self-Propelled:You can choose between a push-style mower and a self-propelled cordless mower. A push-style cordless mower is more like the traditional push lawn mower, where your body provides the power. This is a more budget-friendly option among cordless mowers.

A self-propelled cordless mower’s rear wheels are powered by batteries to drive the mower forward or backwards. While operating the mower, all you’re required to do is to control its pace and direction. This makes for more effortless usage, but also costs more money.

  • Mulching vs no mulching: A lot cordless electric mowers come with mulching and bagging options for the grass clippings that are being cut by the mower. You can choose to either mulch the clippings as fertilizer or bag the debris to be thrown away.
  • Charge Time & Run Time:

4. Self-propelled Lawn Mowers:

With self-propelled ones, there are quite a few factors to consider before you purchase your mower.

  • Front-Wheel vs. Rear-Wheel Drive: Front-wheel drive mowers are much cheaper than rear-wheel drive ones. If you have to move the mower forward, the wheels must be firmly planted on the ground. In case of uneven or hilly terrain, front-wheel drive models become useless as you may have to lift the front wheels to turn or when the wheels bounce up off the turf. But the rear wheels are always grounded, offering the operator with good traction control and maneuverability.
  • Set vs Variable Speed: Self-propelled mowers with adjustable speed settings allow you the luxury of deciding your own pace. You may want to go faster or slower depending on the conditions of the lawn or on your physical condition. One speed setting doesn’t give you that option. Of course, the more features you want, the more you have to pay.
  • Recoil vs Electric Start: Depending on the way you can start your self-propelled mower, there are two choices – recoil start and electric start. Recoil start mowers are the traditional, pull-rope style. You pull a cord that turns the engine on, and that, it turn, pushes the mower ahead. In case of electric start mowers, all you do is turn on a key or push a button to get the mower running.
  • Wash-out Ports:How you maintain mower determines how long and how well it will perform. A wash-out port on your mower deck ensures better upkeep. Connect a garden hose to the port and turn it on and watch all the grass clippings from the inside the deck and blades getting cleaned.
  • Blade Override:With most self-propelled lawn mowers, the engine automatically turns when you let go of the bail. This is safety feature, called the blade override system. It keeps the engine running, but disengages the blades. Apart from your safety, this also extends your engine life, as it doesn’t have to be turned on and off every few minutes to pick up a weed or a ball dropped by your kid.
  • Swivel Wheels: Your yard can’t possibly be on a completely plain terrain. Plus, it will also have flower beds and trees to mow around. This means, you will have to frequently turn. But, most self-propelled mowers are built to move straight. Due to this, after a few months, the wheels start to wobble, and then ultimately the bolt comes loose and the wheel falls off. Nowadays, some mowers come fitted with swivel front wheels. These are designed for better maneuverability and to prevent the wheels from coming loose.

5. Gas-Powered Lawn Mowers:

With gas-powered lawn mowers, the considerations are quite simple. These are very convenient machines – no effort, no physical exertion, no back pain, and yet faster trimming. But the flip side is that you not only pay more to buy these powerful machines, you also have to bear the gas expenses to operate the mower. Besides, there are additional maintenance costs. And oh, there is the issue with the fumes that you and your neighbor, and gradually the entire earth, has to endure.

Some Common Factors:

  • Budget: This point, although, applies to all types of mowers, have been individually discussed in the above sections.
  • Owner Review: Before narrowing down on the mower of your choice, make sure to read up on some of the owner reviews online. A lot of people, both the happy and the unhappy customers, like to voice their experience. Read up. They will give you a general idea about the mower’s performance.
  • Brand Performance: Brand image has always played the part of a psychological remote control for consumers through generations. It is always safe to go with the reputed brands. That way, even if there is an issue, you can be sure that the company, in order to protect their image, will make amends to replace your item or compensate you suitably.

How to best maintain your mulching lawn mower

Now that you have purchased your new gardening gadget, you need to know how best to maintain it. If you don’t maintain your mower properly, you are most certainly sending it to its early death. You don’t need to be a mechanic to keep it in working condition.

Here are a few tips of taking care of your lawn mower:

  • Read the owner’s manual properly. It has all the safety guidelines and information regarding its upkeep.
  • Drain the gasoline at the end of the mowing season, in case you own a gas-powered mower. Old gasoline is one of the main culprits for a mower not working. It is important you emptied the container at the end of summer each year if you want to ensure your mower’s durability. Pour fresh gasoline at the beginning of every spring. Also check the oil regularly for floating debris or discoloration.
  • Clean the undercarriage for residual grass stuck to it. It can clog the discharge chute and put unnecessary pressure on the motor (in case of motorized mowers). Don’tforget to disconnect the spark plug before you do to avoid any unwarranted accident.
  • Sharpen the blades regularly.There is no point in having a mower and using up all the fuel, battery charge or electricity and over-working your motor. Blunt blades will pull and rip the blades of grass, instead of giving you a fine cut, leaving your lawn looking ugly and unkempt. A mower repair shop can do it for you.
  • If all this is too much for you, take a trip to your nearest mower repair shop after the end of every summer and get a professional maintenance and repair work done.
