Cobra MX4140V Review

Summary

The Cobra MX4140V is a cordless battery lawn mower that has a 41cm cutting deck and comes supplied with a large 40V 4.0Ah battery that will give you around a 30-40 minute run time. The mower comes provided with a large 50 litre grass collection box and a wide range of cutting heights (7 stages, 25mm to 75mm), weighs 19.3kg and is provided with a Cobra 2 year warranty.

Cordless mowers are becoming more and more popular, but one of the things that I have noticed on a lot of models is that there aren’t always as many features as other types of mowers. Of course, this isn’t across the board and there are some cordless mowers out there that are incredibly powerful and have a load of features to boot. This Cobra MX4140V is a fine example of this.

With a 41cm cutting deck, this lawn mower is suitable for medium to large sized lawns, but that certainly doesn’t mean that it isn’t super practical to be used even on smaller lawns. It comes with a handy mulching plug, seven cutting heights and a long lasting battery, so you’ve got a lot of options in terms of how you mow. Moreover, this machine has been designed with user comfort in mind and is bursting with useful features like the ergonomic handle and full flap on the grass box, which makes your life that little bit easier.

For anyone who wants a lightweight and no-nonsense mower that still offers an excellent choice of functions, I’d highly recommend this one is on your shortlist. In my Cobra MX4140V review, I’ll be taking you through the finer details of this nifty piece of garden equipment.

Main Features

  • For Lawns of up to 400m²
  • Blade Length: 41 cm (16-inch)
  • Weight: 19.3 Kg
  • Number of Cutting Heights: 7 (25mm to 75mm)
  • Mulching Plug Provided
  • Grass Box Capacity: 50 L
  • Battery: 4.0 Ah 40-Volt Lithium-Ion
  • Metal Deck
  • Deck Noise: 90 Decibels (79.9 dB at the operator level)
  • Handle: Double Folding with Foam Grip
  • Handle Incorporates a Battery Power Indicator

Power System & Batteries

A lot of people are put off cordless mowers in the belief that they will run out of time long before the lawn is mowed. Thankfully, that won’t ever be the case with this Cobra MX4140V since it comes with a powerful 4.0Ah 40v Samsung battery that will give you as long as 30-40 minutes of cutting time per charge. And even in the worst case scenario when you do happen to run out of power, you’ll only need to wait 90 minutes for it to fully recharge.

Moreover, the power system benefits from a battery indicator that displays a series of 5 lights making it much more accurate compared to some other models that only have a three-light system. What’s really practical about this mower is that there is no need to stop the mower to check the remaining charge, since the indicator is conveniently located on the handle.

The battery is loaded into the front of the mower and is quick and simple to put in and take out. If you have any other 40v Cobra tools, you’ll also be pleased to know that the battery can be shared between tools for your convenience.

Features In Detail

Deck and Blade

The Cobra MX4140V benefits from a steel deck. This material is ideal for outdoor tools like this as it is incredibly resilient and won’t rust or corrode easily. What’s more, it’s fantastically lightweight and durable, so even if your garden is a little more rugged, you won’t need to worry about the deck cracking as you might do with a plastic one.

Cobra use a 41cm lifting, pressed steel blade suitable for mulching. The cuts are clean and lift the grass in and into the grass box. And because of the superb cutting performance, the clippings are small and compacted into the grass box to make the most of the space available.

Height Adjustment

Cobra MX4140V Height Adjustment

This Cobra MX4140V comes with a choice of seven cutting heights which, for a mower of this size, is remarkably generous. What’s even more impressive is how easy they are to shift through. This lawn mower benefits from a central cutting height lever that is smooth and simple to operate.

The cutting heights range between 25mm and 75mm, which is versatile enough for most lawn needs. However, I will point out that some people prefer the lowest option available, to go down to 20mm, so if this sounds like you, you might find that 25mm is not suitable.


Cutting Diameter

This lawn mower is designed with the medium to large sized lawn in mind. It boasts a 41cm metal cutting deck. However, if you have a very small garden, this is likely to be too cumbersome for your needs, but the good news is that Cobra also offers a smaller brother to this model, the Cobra MX3440v which features a 34cm cutting deck made from polymer. This won’t have the same level of durability, but for basic mowing needs, it’ll serve you well. It is also worth keeping in mind that this smaller model doesn’t come with a mulching plug, so if that’s a deal breaker for you, you may want to stay with the Cobra MX4140V.


Handles

I talk a lot about the importance of a good mower handle and the Cobra MX4140V certainly has a lot to offer in this respect. For starters, you will notice that the handle is ergonomically designed making it far more comfortable to use. It features four starter buttons located at different parts of the handle, meaning that you can start the mower no matter how you want to grab onto it. That said, you don’t need to worry that all four buttons need to be pressed at once, they each work independently.

What’s more, the handle provides you with incredibly easy manoeuvrability. Making left and right turns feels effortless, so if you’ve struggled with your lawn mower in the past, that isn’t going to be a problem now.

Roller (Stripes)

Cobra has not added a roller nor a striper to this model. It is not common to see this type of addition on a mulching cordless mower as they are not compatible. If you want to see stripes on your lawn, you are better off getting a push-roller from a third-party manufacturer or see my list of best cordless mowers with a rear roller.

Mulching

Cobra MX4140V Height Adjustment

If you don’t want to use the traditional cut and collect option, this Cobra MX4140V comes with a mulching plug. This allows you to remove the grass box and rather than the clippings being collected, they are circulated around the deck and delivered back to the lawn as a fine material which works as a natural fertiliser. No doubt you will know that there are many health benefits and advantages to mulching your lawn.

Grass Collection Box

This Cobra MX4140V comes with a huge 50-litre grass box which is seriously impressive when you think about the size of the mower. Of course, in any case, it is going to fill up but with the handy full flap indicator, you won’t need to constantly stop and check. When the flap sits down, it’s time to empty.

This hybrid grass box is beautifully strong and durable yet offers excellent circulation, so you really are getting the best of everything.


Performance

I really like how lightweight the Cobra MX4140V is and this means that it is beautifully easy to move around. It is a push mower, but you won’t feel as though you are exerting any effort and the way that it is designed means that manoeuvring it is a breeze; but I will talk more on that later.

One of the other things that makes the Cobra MX4140V cordless lawn mower stand out from the crowd is the excellent cut quality you get. Thanks to an auto adjusting blade you never need to worry about losing power over more stubborn terrain. Should the grass become more difficult to cut, the power is automatically increased meaning you always get an even cut and helps to increase the battery run time.


Practicalities

  • A large lithium-ion battery, which gives the mower a good run time, yet it is still quick to recharge.
  • You can see the battery level on the battery itself or on the handlebar control panel.
  • Option to mulch the grass cuttings with the supplied mulching plug.
  • There is a grass comb at the front of the machine that guides the grass towards the blade ensuring an optimum cut that is closer to the edge.
  • The handlebar is adjustable with quick-latch fasteners and folds down for compact storage.
  • There are 4 starter buttons on the handlebar, so it is comfortable for both left and right-handed users.
  • A half-mesh grass collection bag that folds flat for ease of storage.

Safety Features

Cobra MX4140V Safety Features

If you have children, the last thing you want is little hands getting hold of the lawn mower and starting it up. It doesn’t bear thinking about what could happen. Fortunately, this Cobra MX4140V comes with a safety key which must be inserted into the battery compartment and switched into the on position before the mower will turn on.

Cobra MX4140V Should You Buy the Cobra MX4140V

This Cobra MX4140V would make an excellent addition to the tool shed of any homeowner who is looking for something easy to use and reliable. Thanks to the various mowing features, it gives you a degree of versatility without being overly complicated and this would work great for people who are just getting to grips with a cordless lawn mower or those looking for simplicity and features.

I would also highly recommend this Cobra MX4140V to anyone who has a slightly more rugged garden. Since it is so easy to move around, thanks to the ergonomic handles and larger rear wheels. It offers increased power when the ground gets a little tougher to mow, so would work excellently in this type of garden.

To give you some guidance on which type of customer would suit this model best, below I’ve listed the categories they would fall under:

  • People with gardens up to 400m² in size.
  • People who want a good range of 7 cutting heights that range from 25mm to 75mm.
  • Those that want the ability to extend the run time by purchasing additional batteries.
  • Those that may have other Cobra cordless tools as batteries are interchangeable.
  • Those that like to have the option to mulch the grass cuttings.
  • Those that want a 41cm cutting width cordless mower that is lightweight and easy to manoeuvre around the garden.
  • People who do NOT want striped lawn appearance.
  • Those who like the convenience of having no power cord or have limited or no access to a power source in the garden.

 


Conclusion

I have really enjoyed exploring the Cobra MX4140V and have found it to be efficient, reliable, versatile and easy to use. It certainly isn’t lacking when it comes to providing a precise and efficient performance. Combined with the 2-in-1 cutting options, this is a tool that comes with many advantages and is suitable for medium to larger sized lawns. What’s more, with that generous 2-year warranty, you needn’t have to worry about forking out for some time to come!

Don’t forget that Cobra also have the smaller MX3140V model, with its smaller 34cm deck. This would be better suited for those with smaller lawns under 250m².

I just hope you can get your hands on one, they are so popular that stock sells out fast, good luck!
