The Murray 44cm Cordless Lawn Mower is powered by 2 x 18 volt 5.0Ah batteries, a 36 volt brushless motor and is supplied with a dual battery charger. The 44cm cutting width together with the powerful Briggs and Stratton batteries make this mower ideal for larger lawns up to 640m². This mower is provided with a large 50 litre collection box, 7 height level positions ranging from 25mm to 75mm via a single lever and provides up to 36 minutes of run time. This mower has the ability to cut & collect, rear discharge and mulch the cuttings with an optional mulching plug.

It was great to test this Murray cordless mower on my rear 500m² lawn and put it through its paces. I had high hopes that this mower was going to be top notch owing to all the good reviews it has received, but did it live up to my expectations? Let’s find out.

In this article and my video review below, I show you the unboxing and how to assemble the mower, along with a full rundown of this mower’s specifications and how well it performs in the real world.

When I purchased this Murray 44cm Cordless Lawn Mower, I was investing in the brand, so I purchased the cordless grass trimmer (hedge trimmer will be next) along with the mower, as it allows me to share the batteries across the range.

OK, let’s get on with the review and see if this Murray is still worthy of my top cordless mower recommendation.

This Murray 44cm cordless mower is for owners of medium to large sized lawns that do not want to mess about with petrol or power-cords. Powered by rechargeable batteries, it is compact, and every design aspect is there to make life a little easier.

Power System

Murray 44cm Review IQ18WM44 Power System

This model uses a 1500 watt 36 volt brushless battery-powered motor, which ensures powerful and efficient running. The two Briggs and Stratton 18 volt 5.0Ah batteries are used in parallel in the mower to provide a very respectable 36 minutes of run-time, with the power to cut longer and more demanding lawns and lawn up to 640m².

When I tested this mower on my rather long and damp 500m² back lawn, it just fell short of cutting it on a single charge. When I subsequently trimmed the lawn (1/3 rule) and the grass was dry, the Murray managed to cut the entire lawn with a little left in the batteries. So my experience of the running times of this mower are as follows.

  • Trimming 1/3 of a dry lawn – 550m² to 600m²
  • Cutting a longer damp lawn – 480m² to 500m²


The performance and power from this Murray 44cm cordless lawn mower compares very well with the likes of Bosch and Gtech mowers. Even with my longer lawn, the Murray dealt well with the longer grass and stepped up the power accordingly. If you have very long lawn just don’t try to cut off too much in a single pass as this is not only stressful for your lawn, but also puts your cordless mower under unnecessary strain. Use the good range of cutting heights to start higher and do a second pass on a lower setting.

Murray do provide this mower in a smaller version (IQ18WM37). What’s the difference?

Well the first thing is the smaller 2.5Ah batteries that will charge in 55 minutes but give a shorter run time, so is therefore designed to cover lawns up to 450m².

The other difference is the smaller deck size at just 37cm as opposed the 44cm on this mower and a slightly small grass collection box at 40 litres (compared to 50 litres).

Below is a comparison table so you can clearly see the differences between these two Murray mowers.

Murray 2 x 18 V (36 V) Lithium-Ion 44 cm Cordless Lawn Mower IQ18WM44, Including 2 x 5 Ah Battery and Dual Charger

Battery Charger

This mower comes with a dual charger so that both 18-volt lithium-ion batteries can charge simultaneously. This will charge two flat batteries in 110 minutes on the docks, and the charger comes with a 1.8 metre power cable.

Both the charger and the batteries have a USB-A socket (0.5 amps). The charger’s USB socket can charge the battery or another device. Similarly, the battery can charge or power other portable electronics.

These batteries work across the range of Murray 18 volt cordless tools, so again competing well with the likes of Bosch and WORX range of gardening tools.

Murray 44cm Cordless Lawn Mower Video Review

Features In Detail



Murray blades are steel, precision cut, as expected from a Murray, and these make sharp and efficient cuts. The blades on the Murray 44cm cordless lawn mower have a good lifespan and if looked after will give years of effective use. If you do however need to replace the blade, then they are readily available and reasonably priced.

These blades are simple in design and inexpensive. Blades can also be sharpened with a few tools and basic DIY skills.

I think you will see from my video review how precise and effortlessly the mower cut my lawn.

As I was unable to locate a mulching plug for this Murray cordless mower, I could not test the effectiveness of the blade for the purpose of mulching. In terms of the rear discharge, the blade cut well and the cuttings were discharged from the rear with no problems.

Height Adjustment

The front wheels are 16.5cm, and the rear are 25cm which is a nice touch from Murray as it helps with manoeuvrability and assists with stability of the mower especially when full laden.

There is a choice of seven cutting heights, which range from 25mm up to 75mm. Now, the 75mm may seem high, however, this is to allow the mower to start higher on over-grown lawns and gradually work its way lower. Being and electric battery mower, the motor will stop temporarily when presented with too great a challenge to protect the motor, so again this is a nice touch from Murray.

In summary, this is a great range of cutting heights that will accommodate your mowing needs depending on the season.

The height adjustment is positioned centrally to the mower making it easy to operate. Again, see my video review to see the height adjustment in action.



The handles on this mower are as good as any I have tested. The foam padding is thick enough to make it comfortable to use whilst absorbing any vibration. The handles fold down for reduced storage and as you can see in my video review, this was quick and easy to do. You also have the ability to adjust the angle of the handles to suit a good mowing posture for both shorter and taller operators. During my test, I had them set to mid point and felt just right for my 5’10” (175cm) height.

Another great feature on these handles, that you will not find on many other mowers, is the battery indicator gauge. A simple press of the button shows how much juice you have left in your batteries combined. There is also a gauge on each battery, but having a gauge at the operator level is a nice feature.

Cutting Diameter

The Murray lithium-ion range of mowers, besides having two types of battery to choose from, also has a choice of blade lengths. This version has a 44cm metal blade, but there is the option for a smaller deck size with the Murray 2 x 18 V (36 V) Lithium-Ion 37cm IQ18WM37.

Which one is best? It really does depend on the size and type of your lawn. If you have narrow strips of lawn or many obstacles, then perhaps the smaller 37cm deck size would be a better fit.

Roller (Stripes)

This range of Murray mowers do not have a rear roller, and therefore, this mower will not produce a striped lawn. You may want to consider the LawnMaster 41cm Cordless Lawn Mower if you must have a rear roller.

Grass Collection Bag/Box Capacity

The grass bag on this Murray 44cm Cordless Lawn Mower is collapsible, with a solid top and mesh sides for greater airflow. This design also helps with compacting the bag down for storage. The size of the grass bag is 50 litres. This is my preferred grass collection bag configuration as it not only reduces storage and increases air circulation for better collection, but the hard top prevents dust and debris being thrown up into the operator’s face.

There is a handy fill level indicator on top of the grass collector, as an external visual aid, and the box is well constructed and easy to remove when full.

As demonstrated in my video review, this mower really does collect the grass cuttings well and compacts them effectively into the 50 litre collection bag.

There is a 3-digit LED display on the front of each battery to show the percentage of charge remaining. This means that you can read the charge left on each battery without having to take them out of the mower. It would have been nice to have at least 5 lights as it is difficult to judge how much battery is left when only 1 light is showing. There is also a battery indicator light on the handles, that when pressed will show the remaining the battery charge, again using the 3-digit LED display.

The power pack that comes with the Murray 44cm cordless lawn mower makes life easier by having two docks to fast charge the batteries. The batteries sit under a cover in the mower, away from flying grass clippings.

Convenient for storage, the main handle folds in two-halves to become the same height and length as the mower. To make the controls more comfortable for operators, the handle is adjustable with three different heights. And the handrail, covered in a soft foam grip, helps to absorb vibrations from the spinning blade.

To make the motor even more efficient and the batteries last longer, there is a Soft-Start function. The Soft-Start slows the acceleration of the blade when starting and will take around 3 seconds to get to full speed.

All wheels on the Murray 44cm cordless lawn mower are solid, so there are no issues with repairing a flat tyre. And behind the front wheels, grass combs pull grass under and in-towards the blade, so it will reach grass up to the width of the machine.

Safety Features

Murray 44cm Safety

A single handle for blade height adjustment means that there is no reason to go around to the front when the machine is running. Everything except for removing the battery is possible to adjust from the back of the Murray 44cm Cordless Lawn Mower.

These are lithium-ion batteries, and as such, can overheat if the operator tries to mow thick grass. To prevent this from happening, a 30-amp Load Protection will shut the power down until it cools off. In this cooling-off period, the operator should increase the cutting height and try again.

The deck is plastic, this is a good thing for a cordless electric mower to help absorb the noises from the blade and the motor, as well as reducing the overall weight.

To activate the mower, the operator first needs to insert a key in the slot, behind the batteries, underneath the main cover. The operator should remove the safety key, along with the batteries, when doing any maintenance on the unit. Always refer to the manual for complete details of the safe use of this mower.

To get the mower running after activation, there is a safety button that needs releasing before the throttle handle will move.


These cordless series mowers from Murray are a 2-in-1 out of the box, meaning they provide a collecting and rear discharge function only. There is the option to purchase a mulching plug, for both Murray models (the 37cm and the 44cm).

This would not only extend your mower to include 3-in-1 cutting features, but will also provide the essential benefits that mulching has to offer. To find more about the benefits of mulching read my article – The Benefits of Mulching Lawn Mowers – Complete Guide.

As mentioned above, I was unfortunately unable to test the mulching in my video review as the mulching plug was currently out of stock. I did however test the rear discharge cutting option and this worked as expected.

Below is a link to the mulching plug for this Murray Cordless Mower.

Should You Buy This Model?


This Murray 44cm Cordless Lawn Mower really compares well to other brands such as Bosch and WORX in terms of build quality, performance and practicalities. It was difficult to find any negatives with this mower, apart from the mulching plug not being supplied as standard (has to be purchased as an optional extra), having only 3 battery indicator lights can make it a little tricky to gauge when the batteries are running low on charge.

Admittedly, the Murray is not the cheapest mower of its size on the market, however you are getting a very good quality mid-range mower that delivers features and performance that really will give a great cut and make mowing the lawn that much easier and enjoyable.

As lawn mowers go, this is one of the more environmentally friendly machines that you will find. For sure, it does not emit fumes like a petrol mower and is significantly quieter, I measured its sound level at operator’s level at 101 dB.

No cables are powering this mower, so you do not have to worry about slicing through one as you go around the lawn. And the batteries are conveniently compatible with other Murray cordless tools.

Remember you are getting an impressive 5 year warranty with this mower, with 3 years on the battery and charger. You simply will not get this with any other brand and shows real confidence on the longevity of this Murray cordless mower.

Murray 44cm Review Conclusion

The only slight negative I could find with this Murray 44cm cordless lawn mower is that it is slightly louder than others I have tested. Now this maybe due to the powerful 5.0Ah batteries pushing the motor and giving more torque. To give you a comparison the sound level on this mower according to the manufacturer is 96 (dB), compared to the Bosch Rotak 43 LI at 76 (dB), this isn’t much, but I thought I should mention it anyway.

Machines make noise, and this is unavoidable, efficient batteries such as lithium-ion are the way forward. It is not only about the noise, but the cost to the environment. Petrol will become more expensive, and the cost of recharging two 18-volt batteries is nominal.

The large back wheels make a lot of sense for a full grass-laden machine, where most of the weight will sit. These solid wheels are thick and sturdy, which takes away another potential issue that less well-made mowers may have.

Some genius design touches make this Murray mower less work for the operator. Being able to see the battery power reserve with a push of a button from the handles is convenient. In addition, the level indicator on the grass collection box is handy to see when it is full and needs emptying. Being supplied with a dual charger is also another time-saving feature that is missing on so many other brands.

These little details will go unnoticed in the beginning, but you would notice if they were gone. If you are into new technology and plan to build an arsenal of cordless Murray tools, then you will not be disappointed with this very impressive cordless lawn mower.
