Summary

Cobra GTRM38 Review

The Cobra GTRM38 is an electric lawn mower that has a 38cm (15″) cutting deck and comes supplied with a large 40 litre grass collection bag and a rear roller for a striped lawn appearance. This mower has a wide range of cutting heights (7 stages, 20mm to 75mm), weighs 17kg and is provided with a Cobra 2 year warranty.

When I heard that there was an electric lawn mower that was such good value for money that still came with a whopping number of features, I was blown away. The Cobra GTRM38 is lightweight and yet an amazing little performer. With a 38cm cutting deck, it is the perfect mower for medium sized lawns and thanks to the 1600w motor, you can mow even the most challenging lawn. The 10m power cable is a standard length, so if it coves your lawn you will have no need for trails of extensions cables.

What’s really great about this Cobra GTRM38 electric corded mower is that it comes with a wealth of mowing options that are, for all intents and purposes, comparable with something much more expensive. You are getting two mowing options; either cut & collect or mulching as well as seven, yes seven cutting heights and a rear roller! It’ll cut to the edge and beyond making this one of the most effective and easy to use electric lawn mowers I have seen in recent months.

In my Cobra GTRM38 review, I’d like to take a deep dive into the many features and give you a clear indication of whether this is the right piece of equipment for you. So, let’s get started.

Main Features

  • 38cm cutting deck
  • 7 cutting heights from 20mm to 75mm
  • 1600w motor
  • Larger rear wheels for improved manoeuvrability and stability
  • Corded electric
  • 10m power cable
  • 40 L hybrid folding collection bag
  • Mulching plug included
  • Comfortable padded handles
  • Quick release folding handles

Power System

The Cobra GTRM38 electric mower runs on a super reliable and smooth 1600w motor. This offers a very adept amount of power considering the size of this mower. Now, it is important to keep in mind that this is just one of a collection of mowers, all designed for different garden sizes (for more information about the differences please see my comparison table below). If you have a larger garden, you might opt for the more powerful GTRM43 which runs on an 1800w motor. It has a larger cutting width and just a little more get up and go. Alternatively, the GTRM40 is also larger with a 40cm deck, but runs on the same motor as this Cobra GTRM38. So as you can see there are many choices to accommodate individual needs.

Cobra GTRM Range – Power Comparison

  • GTRM34 – 1300w motor
  • GTRM38 – 1600w motor
  • GTRM40 – 1600w motor
  • GTRM43 – 1800w motor

Features In Detail

Performance

This is a hand propelled mower but thanks to its lightweight design, it doesn’t feel like a strain, so if you have been used to a self-propelled mower, you won’t feel a huge amount of difference.

What really impressed me about this Cobra GTRM38 mower was how cleanly it cuts. Even in tough grass conditions, it performs incredibly well and leaves you with an even finish. What’s more, it’ll cut to the edge thanks to the strategically positioned four wheels and a rear roller, but I’ll go into that a little more later on.


Deck and Blade

The Cobra GTRM38 benefits from a 38cm cutting deck made from a strong polymer material. This offers durability while allowing the equipment to remain lightweight.

Earlier, I touched on two of the larger brothers to this model, but if you have a smaller garden, you might find that the Cobra GTRM34 is more suitable for you thanks to the 34cm cutting deck. Have you guessed yet that the model number in the name refers to the cutting width? Also do keep in mind that this smaller brother does run on a less powerful 1300w motor; but that still is nothing to be sniffed at.

This Cobra GTRM38 also makes use of a sharp rotary blade that offers a very competitive performance.

Cobra GTRM Range – Deck Size Comparison

  • GTRM34 – 34cm deck
  • GTRM38 – 38cm deck
  • GTRM40 – 40cm deck
  • GTRM43 – 43cm deck

Height Adjustment

Cobra GTRM38 Height Adjustment

Having the ability to adjust the cutting height is one of the most important things to look for when choosing a lawn mower, as this allows you to cut the grass to varying levels depending on your preference and lawn conditions. What’s great about the Cobra GTRM38 is that you are getting an incredible selection of cutting heights, including a low 20mm cutting height for that bowling green finish.

There are seven to choose between and these range between 20mm and 75mm. Moving between them is super simple thanks to the inclusion of a single lever height adjustment mechanism that takes the hassle out of what was once a very trying task (where each wheel had to be adjusted separately).


Handles

Cobra has left nothing out when designing this lawn mower and again, I have to reiterate that this is an incredibly affordable lawn mower. But for this price you are getting something that is designed for your comfort. It features soft touch handles that allow you to get a good grip and won’t risk you being left sore or uncomfortable after a longer mowing session.

What’s more, the control handle runs the full width of the bars, making it easy for both left and right handed people and for turning around obstacles on the lawn.

When you’re done mowing, the quick release handles allow you to fold the mower handles down at two points for easier storage. This is great if you are limited on space in the garden shed.

Wheels

Earlier, I mentioned that the Cobra GTRM38 benefits from four wheels as well as a rear roller. This is not something that you see combined on many electric lawn mowers particularly those that have a mulching plug option included too, so these certainly are features that set it apart from the rest. I was so pleased to see that Cobra have provided larger rear wheels for improved manoeuvrability and stability too.

This design means that cutting to the edge of the lawn is extremely easy and will even allow you to mow over the edge of borders, thanks to the roller. What’s more, the roller will leave you with an attractive striped finish that will make your garden look perfectly manicured.


Roller (Stripes)

Unlike the equivalent cordless range of Cobra mowers, Cobra have added a rear roller to this GTRM38 mower to produce a striped lawn appearance. Just bear in mind that, as with all electric mowers, they are lightweight and will not produce a defined and long lasting stripes that you would achieve with a heavy petrol mower.


Mulching

Cobra GTRM38 Mulching

As well as being able to use the traditional cut & collect option, the Cobra GTRM38 also comes with a mulching plug. This can be inserted into the back of the mower and rather than the grass clippings being collected, they will circulate around the cutting deck and get chopped into fine pieces.

Once this has happened, the clippings will be returned to the lawn, sinking down to the lowest level and delivering essential nutrients that will make your grass healthier and greener!

Grass Collection Bag

The Cobra GTRM38 comes with a 40 litre grass collection bag which is easy to attach, remove and empty. It features a full indicator so that you always know when it is time to empty.

Should You Buy the Cobra GTRM38?

Cobra GTRM38 Should You Buy the Cobra GTRM38

This is a great lawn mower for anyone who wants something that is lightweight and easy to use, but that doesn’t sacrifice on other important features. If you are looking for something that is versatile and won’t break the bank, then there are not many other mowers that I would recommend more.

A lot of people are concerned that when mowing their medium sized lawn with an electric mower that the power cable won’t provide enough reach. This mower comes with a standard 10m cable, which is perfectly suited for the intended size of the garden, however if your lawn is larger then you will need to use an extension cable or have additional power sockets positioned around the lawn.

I would also recommend the Cobra GTRM38 for people who need something that is powerful enough to tackle challenging grass conditions. Since this runs on a 1600w motor, it is perfect for longer or denser grass and will still provide you with an impressive result.


Conclusion

The Cobra GTRM38 is one of the best electric mowers I have seen in a while. While a lot of people are moving away from corded mowers and opting for cordless, I can see why you’d want to stay with electric when I look at how amazing this product is at a fraction of the cost of an equivalent cordless mower. With enough versatility for most domestic needs and a reliable motor, it has everything you would expect from a lawn mower and a little bit more for good measure.

Cobra are renowned for their build and component quality and this Cobra GTRM38 is no exception. What’s more, with this product you will also receive a 2 year domestic manufacturer’s warranty.

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