Cobra Cordless Lawnmower Types

There are several sizes and variations of Cobra Cordless lawnmowers available, so we have focussed our review on 3 types namely the Cobra cordless 34cm, the wider and more powerful Cobra Cordless 43cm and also the Cobra 41cm Rear Roller cordless version.

Cobra Cordless Lawnmower Review – 3 Popular Options

Option 1: Cobra 34cm Cordless Hand Propelled Lawnmower MX3440V

The first recommendation is the lower priced Cobra 40V Cordless hand push Lawn mower code MX3440V that comes with the 40V 2.5Ah lithium ion battery, a charger and it offers a mowing path width of 34cm or 13 inches. Recharging this battery takes around 75 minutes to complete, the motor is brushed (not brushless) and you can expect to get 30 to 40 minutes mowing time from the battery depending on mowing, grass and terrain conditions.

It’s a basic cordless lawnmower to suit those looking for the best possible price so there is no additional spare battery, no rear rollers, no mulch plug, no self-propelled support and it has the narrower frame of just 34cm width. There are 5 mowing heights options that are controlled with a single lever and it can mow from 2.5cm up to 7.5cm.

The grass collection box has a capacity of 35 litres, the weight of the unit is 12.5kg and it comes backed with a 2 year warranty from Cobra. A cordless lawnmower like this is best suited for lawn sizes up to 250-300m2 in our opinion

Price Guide: £180 - £230

Option 2: Cobra 43cm Cordless Hand Propelled Lawnmower MX4340V

For a wider mowing path and a more powerful battery for dealing with tougher mowing conditions and larger lawns, then you should consider the more expensive Cobra 43cm wide Cordless 5Ah battery Lawnmower code MX4340V that will do a much better job overall and make the mowing work a lot easier for you to do.

Yes it will cost you more but it is more equipped for dealing with larger mowing jobs that require the extra power you get from this 5Ah battery. There is no rear roller, no mulch plug or additional second battery so it is still more affordable that many other brands – plus the motor is brushed not brushless. The 40V charger is included and you get 5 mowing heights from 2.5cm to 7.5cm, the grass box is larger at 50L and it is designed for larger lawn sizes 400m2 to 500m2 in our opinion.

Recharging usually takes around 90 minutes, the battery mowing time ranges from 35 to 45 minutes depending on grass conditions and it is also covered with a 2 year warranty.

Price Guide: £280 - £320

Option 3: Cobra 41cm Cordless Rear Roller Lawnmower RM4140V

For a tighter lower cut supported with a rear roller for stripes, then you should choose the Cobra 41cm Cordless Rear Roller Lawnmower code RM4140V instead which comes with the 40V charger and a single 4Ah battery.

It’s a much heavier machine at 22kg and the battery mowing time tends to be slightly less to support the heavier weight and the tighter cut so bear this in mind when making your selection. It has 7 mowing heights that range from 2cm to 7.5cm and it comes with the Cobra Samsung 40V Lithium-ion battery that takes around 80 minutes to recharge and will give you 20 to 30 minutes mowing time depending on mowing conditions and mow heights selected.

This lawnmower weighs around 22kg, the grass collection unit has a capacity of 50 litres and it also comes with the 2 year warranty as expected.

Price Guide: £370 - £420

Pros for the Cobra Cordless lawnmowers (7)

  • There is a great choice of lawnmowers to choose from – you can get the cheaper and basic MX3440V model without the rear rollers, mulch plug and one 2.5Ah battery or you can select other more expensive models that do offer these extra mowing features and more powerful 5Ah batteries
  • You are not limited to the length of power cords so you have more freedom when doing your gardening and mowing work – no cords on the lawn as you work
  • There are no maintenance costs like petrol lawnmowers as there are no fumes, no oils and no fuels to worry about so you save money in the long term.
  • The lightweight design of the MX3440V is impressive especially around corners and difficult obstacles and it gave a really good quality cut and did a satisfactory job when it came to collecting all the grass clippings
  • Batteries appear to be able to manage most small to medium sized lawns be it 250m2, 300m2 and in some cases even up to 500m2 when a light trim is needed on the more powerful batteries
  • Noise levels from these cordless lawnmowers is far lower than the petrol lawnmowers and you have the push button start instead of the pull cord
  • It can handle longer grasses quite well as long as you start with the higher setting 5 and work your way down on the second pass

Cons for the Cobra Cordless Lawn mowers (6)

  • There are only brushed motors in place – not the brushless motors that you see available in other premium brands
  • These lawnmowers are hand pushed so you need to do all the pushing yourself (alternative models in the Cobra portfolio are electric self-propelled but much more expensive)
  • The recharging time is well over 1 hour where other brands have quicker chargers than this
  • Difficult mowing conditions, denser and coarser grasses will deplete the battery charge a lot quicker
  • There are no second batteries available in the packs (which explains the lower price point)
  • There are no rear rollers or mulch plugs included in the MX3440V or MX4340V but are available in other more expensive models within the wider Cobra range

After completing our Cobra Cordless hand push lawnmower review, we hope our work here can give you a better idea of what these lawn mowers are all about and what they can offer you for your own mowing gardening jobs.

Which one would we choose? It depends on the garden size – if I had a lawn 200-300m2 I would choose the MX3440V but if my lawn was larger 400-500m2, then I would choose the MX4340V instead. These lawnmowers performed much better than expected so we have no hesitation in recommending them to the wider public and further information, reviews and price updates can be viewed below
