    We have a large garden so battery runs outEasy to use – although the grass collector keeps falling off.We have to recharge batteries in between the cut as we have a large lawn but cuts well

  2. Mike

    Expected better for the price paidI have been left a bit disappointed with this cordless lawnmower. Firstly, if you have never used a cordless one before you will find it a great time saver and the benefits are pretty much the same on all the different brands. This one does include a handy battery status check on the handle so you can easily see if it is about to run out. Despite this, for this price bracket you will find better ones out there.Firstly the mower struggles with longer or thicker grass. I found either the battery died quickly or it would shut down and need a clean before it could get started again. Also bear in mind whilst there are 2x 2.5AH batteries included, you will still get 2.5AH capacity and not 5AH.Overall, for the price paid, I expected better performance.

    Murray 44cm Dual 18v Battery Cordless Mower With 50L Grass Collection BoxMurray 44cm Dual 18v Battery Cordless Mower With 50L Grass Collection BoxI managed around 60 square metres on mowing level 4, in 7 minutes 10 seconds. I have varying levels of mowing difficulty on the lawns. Afterwards there was 95 and 96% charge remaining in the batteries.1.5 week interval. Batteries untouched. Second mow on level 3, in 6 minutes 43 seconds. 75 and 76% charge remaining.2 week interval. Batteries untouched. Third mow on level 3. 56 and 57% charge remaining.I actually achieved 5 mows of 60 square metres, out of one battery charge over a 10 week period. Leaving 8 and 9% charge remaining after mow number 5.I’m impressed.Why the Murray?*Cutting width 44cm = less runs up and down.*Weight 14kg = pressure off my knees and back.*Run time 36 minutes = enough for all my lawns, multiple mows on one battery charge.*No power cables and petrol required.*Guarantee 5 years and 3 years battery = peace of mind.What Came Out Of The Box?First Out Of The Box = ManualsLarge due to translations into many languages. The English instructions are short and simple enough to follow. There is also a quick start tag on the mower showing operating advice.Next Out = Batteries and Dual ChargerSimple to slot into the charger and view the charging light indicators. Flashes green whilst charging. Solid green when charged.The charging unit has a useful additional USB charger for an additional device. Each battery also has a USB output and can act as a power bank. All 3 items have 5.0V 1.0A USB output.Each Briggs and Stratton battery has a digital display indicating percentage charge remaining. The 18v 5Ah batteries arrived with 96 and 97% charge respectively. Topped up to 100% in no time.Last Out = Mower14kg with a central handle to lift the mower. Additional grass box, handles and screw fittings.Assembling The MowerShort instructions because there are only a handful of things to do.1.Put the 2-part handle together and screw in the quick release levers, pull the levers to lock.2.Place the cables in snap on cable holders.3.Clip the grass collector to its metal outer and insert.Done.Grass Collection Box50 litres. Ample for my 60 square metres or so.Weight15kg in the box. Feels light as a feather at the handle when assembled. Compared to my outgoing, trusty, petrol, 46cm, rear roller beast of 15 years this is like cutting the grass with a yard brush! It is light and manoeuvrable. What a breeze.Visual AppealWhat a cracker. Love the silver, black and green. See my pictures assembled in the kitchen. I actually stood with my arms folded in satisfaction and admired the mower for quite a while.First Cut Of 60 Square MetresLawn ConditionsMy grass was long in summer. (Due to weeks of rain!) I waited for a dry day.I waited a while. I chose to cut on a dry morning after overnight rain. I had a few hours window before the next showers. My grass was ranging from 4 to 6 inches in height by this time and the base was wet. It was like the first cut of spring and a good benchmark. I chose mowing level 4.My lawns are split. A simple square cut, and tricky runs around lighting posts and swings. After the sad passing of my petrol mower. I borrowed a 36cm cabled mower. Cut, edging and tidy up took an hour or so on the cable.Mower PerformanceThe Murray decimated that one hour time. I finished both lawn cuts, the simple square lawn and the tricky one in only 7 minutes 10 seconds with 96 and 95% charge left in the batteries. I made only two trips to the wheelie bin with cuttings in the ample 50L grass box. The edging and clean up took the usual time. But the mowing was a doddle.Freedom To MowThe mower was straight out of the shed and into action. No petrol required. No electric cables to set up (and avoid!). Light and easy – the blade felt powerful in action. I moved at a good pace and the grass was cut well, even in the wet(ish) conditions.Run Time & Battery ChargingObviously I am going to get a number of mows out of 1 charging cycle. At the time of writing I do not know the charging duration of depleted batteries. The manual states the mower can accomplish 640 square metres of mowing in 36 minutes. I believe it. I managed around 60 square metres in 7 minutes 10 seconds with varying levels of mowing difficulty. There was 95 and 96% charge remaining in the batteries. The question is: will I get 5 more mows out of the batteries? …watch this space!UPDATEMOW No.1: 96 and 95% charge remaining, level 4, 2 grass buckets1.5 week intervalMOW No.2: 75 and 76% charge remaining, level 3, 2 grass buckets2 week intervalMOW No.3: 56 and 57% charge remaining, level 3, 1 grass bucketOverallVery pleased with my purchase.I have limited time. This mower offers me opportunist mowing at the drop of a hat in 7 minutes. It is an attractive mower. Light, manoeuvrable, powerful with good grass collection capacity. The 44cm cutting width means less runs up and down. Long battery life. Good run time and guarantee. I am happily leaving petrol and cables behind.

    Works great on my medium-large lawn!With this being my first battery mower I was unsure as to how it would handle my lawn and I was most impressed. The assemble was very basic being almost primitive and it was up and running in under 10 minutes of arrival! I was too impatient to wait for the morning dew tp dry so took my brand new machine out for a test and I was thoroughly impressed. The lawmnmower is light and very easy to manouver while also feeling very sturdy in the hand. I found that you do need to make sure the bucket is attached correctly as a number of times I found fallling off due to user error. As for the batteries they did need recharging as the grass was damp and left uncontrolled for roughly 3 months however that was to be expected. I will also mention I bought this product with the rest of the 18v line up allowing batteries to be used across the tools which is very handy. This lawmower has made gardening more fun for me!

    Struggles with thick grass and batteries not that strongIt’s fine and does the job. But I can’t do my front garden and rear in a single charge.I need to recharge about 2/3 way through the job.I’m mowing excessively at the moment because of the speed my lawn is growing at, so I’m using it twice a week and only on setting 4. So it’s a relatively high cut.I’m finding if I leave it a week, the lawn has gown too much and is too dense. So not only does it not have the power to cut through, but the batteries run out much quicker.It’s not a bad mower… it’s alright… but it just suffers with the issue most battery driven things do. Not enough power vs a corded or petrol one, and runs out of juice too quick.But I’ve rated it 4* overall as it’s better than messing with a chord – especially for larger gardens, and also less weight/hassle than a petrol one.You’ve just got to either do it often to keep the demand on the batteries down, or resolve yourself to needing to charge the batteries part way though.

  6. Steve Hill

    Convenience of a good battery mowerQuite easy to assemble. The mower uses two powerful 5AH batteries and there is an odd arrangement where you have to insert a dongle to complete the connection. Why is not immediately apparent to me.Have only used it twice, first at the end of last season when I completed my almost 200 sq mtrs garden with battery to spare and 2nd, the first cut of this season, when I ran out of juice 75% complete. Run time is quoted at 36 mins and it probably exceeded that slightly. The batteries took less than the quoted 110 mins to recharge. The much longer grass at the beginning of the season is probably the reason I could not complete the lawn without recharging.The mower is easy to operate, the cut is good, the cutting height easy to change (5 settings), and the collection bag adequate – it is bigger than most other mowers i reviewed before buying. When I bought it I couldn’t find any replacement natteries but I see they are now available at £85 each on Amazon. This is an extortionate price, so one must hope they last the 3 years limited warranty given.Overall, I’m pleased with the purchase. It’s expensive but so much easier to use than the corded mower I had. Why not 5 stars? The expense and because I expect that battery driven tech will continue to improve. Although I’ve not operated other battery mowers, am prepared to accept that this probably one of the best available now.

    Powerful battery mower that gives a great cutWe have quite a large garden – half an acre – with most of it laid to lawn. This battery-powered mower doesn’t do a bad job of tackling it. I probably wouldn’t have bought this, if i) I hadn’t seen it on offer just after my brother had sent me money for my birthday, and ii) I didn’t already own a Sprint leaf vacuum that uses the same twin battery system – which means that I have a backup set of batteries. Our garden is divided into several lawned areas, and using two fully charged sets of batteries I can get around roughly half the garden. The battery charger is quite quick, and by the time I have exhausted my spare set of batteries, the first set are nearly recharged and ready to go again. The mower is really easy to use, so light and manoeuvrable that even though I’m waiting for a major operation I can manage to get this all round our garden, including tiered areas where I have to lift. The mower starts easily using a simple press button system. There’s no cable, no starter cord to pull, and no fumes. In use, it’s really quiet, and gives a really nice, neat, short cut to our lawns. I’m generally very impressed.I have one small negative comment in relation to this, and have found one associated issue. The negative comment is in relation to the grass catcher: the pegs for attaching this to the mower go in to slots on the machine that are quite small, get clogged with bits of grass and hard to see – it’s easy to miss and not get the catcher properly aligned. This is a niggle rather than a problem, and once you know that the catcher needs a bit more attention you give it. The issue I have found is that this doesn’t seem to like being used just after the lawn has been scarified. We have lots of problems with moss, weeds/grasses from the adjacent fields, and an underlying soil that is heavy clay and (until recently) had a scarifier that doesn’t include a catcher. At other times, this mower works perfectly but trying to go over a lawn that has been scarified shortly before, to pick up after the scarifier, and the automatic cut out on the mower kicks in and shuts it down, something that hadn’t been an issue with our old petrol mower.

    Excellent Lawn MowerI dropped a star because the grass box kept falling off, I had to thrash it with a hammer and now its fine! The batteries last well, and if you charge them up after you have mowed the lawn and take them off the charger, they are still fully charged two weeks later, and probably would be for many more weeks. I find it easy to use and very light which is great as I am getting on a bit. Assembly wasn`t all plain sailing and I got the screw on side things the wrong way round after following a video on youtube where the guy did the same. There are lots of height settings which is handy if you`ve let the grass get too long. It`s fairly quiet-ish and is such a luxury having no power cable to drag along and get in the way. All in all I am very pleased with the mower, it has made the job so much easier and considerably quicker, so I can avoid the nosey neighbours more easily. I have only used it 3 times so far and will update this review if anything changes.

    Batteries about 40 minutes. Assembly easy. Instructions dreadful. Fix the simple things!My first impression of this machine was putting it together. Instructions and images are dreadful. It’s actually quite simple, but you don’t realise this. But two of the screws you need to unscrew the nuts first. (PS large ones down the bottom. They don’t even tell you that!). I was looking for the nuts and an aborted call to Amazon later then I figured it out. As I say the small images and spare instructions are absolutely dreadful. Sort it out. How can you build a machine like this, so much R&D etc and get some idiot to draw up the instructions. Literally so bad. It really beggars belief. I could do it myself in 10 minutes for you now having spent an hour on it. What is SO difficult! Half a star off for this and think yourselves lucky.OK so got it up and working. Fairly light. About the same as our previous 10 year old electric Bosch which was a 34 inch. But of course no cables. Great news. I reckon I got as much as 40 minutes from the first run. Fairly heavy grass and I probably cut too low. But that reached maybe 300m2 of the 450m2 or so I needed. They say “up to” 640m2 but I’m guessing that’s on a high cut and a lawn that’s 1m by 640m with one simple straight run. Not many of those around. So it stays about the same for 36 minutes as promised but half a star off for the 640m2. By the way I ran out of battery, recharged for 25 minutes and that gave another 150m2 or so. But quite frankly if I have to cut the lawn for an hour I want it out of the way so bollocks to tea breaks etc while it’s done. I’ve decided I’ll keep it but I’m going to have to buy another 2 batteries. Here’s the problem. The batteries cost £79 each, that’s £158 for two. That’s more than half the cost of the original mower. Another half star off which makes 3.5 but I’ll generously round up to 4 stars. That’s for the colour and design, neighbours are blown away!By the way a few posts about the grass holder but it’s fine. My lawn’s pretty flat. no issues, it didn’t come off when I put it on properly. Somebody mentioned the chrome bar, make sure it’s underneath and outside, maybe that was the isuue. If you’re running over all sorts of bumps and rough terrain then maybe it’s an issue? I don’t know.But, now it’s built, I like it. 4 stars overall. Meanwhile I’ll overlook the over selling of the pointless USB feature which quite frankly, come’ on! Who the hell needs that?! Except the guy with the 635m long garden whose got 5m of charge left to charge his phone and call back to the house to come and pick him up.

    Lightweight, highly effective, a joy to use. The manual could be improved.This is a brilliant machine and I wish I had bought it years ago. I’ve struggled with a wired electric mower on our relatively small lawn (100 square metres or so) for years so switching to a battery-powered mower was a revelation. It took me less than ten minutes to mow our lawn – half the time it used to take – and the batteries were still indicating a full charge afterwards. I am seriously impressed!However, (sorry about this Murray, you must hate the ‘howevers’) I did struggle more than I should have done with the assembly, and note from the questions above and other reviews that I’m not alone in this respect. Being nearly 70 years old and doubtless with slightly less than perfect eyesight, the diagrams in the manual were too small to be useful and the associated figure text was so small as to be virtually illegible. Figures 2, 3 and 4 were basically useless for me although I guess those with younger eyes probably struggled less!The text refers several times to the Safety Key but never once mentions where it is located. I only realized after I had completed the build that Figure 6 shows it; since I struggled with the diagrams I was relying on the text. It really wouldn’t hurt to write its location in the manual (it is inside the battery compartment). This caused a delay of 10 minutes as I hunted through all the boxes several times believing I had somehow missed it in the unpacking and I was on the point of giving up when I finally located it.Also unclear in the manual is that the upper and lower handle cam locks are different, and again Figures 2 and 3 are so miniscule as to be useless to me. The lower cam locks have no nut attached and are the longest of the two pairs. These simply screw into the holes provided which are suitably threaded for the purpose. The upper cam locks come with the nuts attached and these have to be removed, as do the washers. The bolts are then threaded through from the inside of the handle to the outside where the washer and the nut are attached. Figuring all this out caused a further 10 minute delay. Maybe for some folks this was all obvious, but it wasn’t to me.I could not find any mention of the two cable clips, so wasn’t really sure quite where to locate these on the handle. They were not even shown in the ‘Features and Supplied Items’ list. So I just put these where they seemed to be the most effective but have no idea if that was what the manufacturer intended.If I were to assemble another one now it would take no more than 10 minutes, as it was it took about half an hour with a not inconsiderable amount of frustration. It was a good job that once assembled and used, the mower was so brilliant that it made it worth the bother.My advice to Murray – do more engineering like this, but improve your manual! Great product.
