Using the supplied batteries expect to get 15 minutes of average length grass cut. I use 2x6ah flexvolt batteries which just about doubled this but is still quite poor compared to the Makita. This is coming from someone who owns nothing but Dewalt. My friends Makita is superior in every way. Another friends AEG is a monster with the same battery setup.1 year later and the mower just wont start. I cannot find the receipt so as far as Dewalt are concerned I am not a customer. I have pulled the mower apart and everything is mechanically sound except for a rusted bearing and drive shaft (cheap chroming). The problem lies in the electronics. There is a switch half way up the handle that gets stuck. This is not the issue. The safety key is known to fail. This too is not ... MoreUsing the supplied batteries expect to get 15 minutes of average length grass cut.

There is a switch half way up the handle that gets stuck. This is not the issue. The safety key is known to fail. This too is not the issue. The issue is the controller module is fried and nothing wants to power on. This is a $350 item. Why would I pay more than half the price of the mower to only get back a sub-par mowing experience and a good possibility of a repeat failure? I am currently looking at wiring up my own controller and battery system but this is hardly a satisfactory solution.I DO NOT RECOMMEND

I have a lot of other dewalt tools and batteries so can’t relate to people saying poor battery time. From what’s I have timed I get 18-20 minutes depending on the temperature of the day and length of lawn from the 5AH batteries this comes with. If 18-20 minutes isn’t enough to mow your lawn the cheapest option is buy a second charger and then both batteries will charge up ready for use in about 1 hour. If you don’t already have any other dewalt gear I would recommend buying the started kit with the 6ah or 9ah batteries and a fast charger or dual bay charger if your lawn takes longer to mow. I use 12ah batteries and get about 45-50 minutes which is plenty to mow my 800m2+ of lawn then use the same batteries on my dewalt line trimmer to do the edges and 54V dewalt ... MoreI have a lot of other dewalt tools and batteries so can’t relate to people saying poor battery time.

I bought this lawn mower in March 2021 because I have an aversion to the unnecessary burning of petrol. I also already had a bunch of DeWalt tools (and batteries). We were moving to a country property with plenty of lawn to mow, and I wanted to use it instead of the capable but petrol-powered Deutscher slasher that we already had on the property.The mower does the job, and I do indeed mow the whole lawn with it, but it didn’t meet the high standard I’ve come to expect for DeWalt tools. Its main drawbacks are a lack of power/torque and run-time. It’s also not cheap, which I wouldn’t mind if it had the equivalently high performance - but unfortunately, it doesn’t.I don’t even bother running it on my 5 Ah batteries because they achieve such poor run-time and power. ... MoreI bought this lawn mower in March 2021 because I have an aversion to the unnecessary burning of petrol.

Its main drawbacks are a lack of power/torque and run-time. It’s also not cheap, which I wouldn’t mind if it had the equivalently high performance - but unfortunately, it doesn’t.I don’t even bother running it on my 5 Ah batteries because they achieve such poor run-time and power. It performs better on the Flexvolt 6 Ah batteries (which mine came with), though it doesn’t hesitate to cut the motor as soon as it hits any moderate length of grass at any moderate sort of speed. It performs moderately better with the 9 Ah batteries and substantially better with the 12 Ah batteries. For this reason I generally use it with my 12 Ah batteries, because it cuts out less and run-time is decent. I’ve only got two 12 Ah batteries though, so I usually mow the lawn in blocks, rotating over days or weeks, so that I can recharge the 12 Ah batteries and run it only on those.I was initially reluctant to buy this mower because I wanted a higher-powered one running at 54V and was hoping DeWalt would soon release one. However when I called DeWalt to ask about it, I was told no such mower was on the cards, and that this mower was actually well-rated by customers. Having used it though, I think a 54V version is indeed needed, though I presume it’d have to run with the larger batteries to achieve reasonable runtime (12 Ah or 15 Ah). Or maybe running two 54V batteries in series to provide 108V would be the way to go? I hope the engineers are working on it.I don’t use my mower with a catcher as I like to leave the cut grass on the lawn to compost down. However, leaving the catcher off means the rear flap stays down and the cut grass can’t escape easily through the rear hatch, even though the flap is shaped in a way that can’t be fully closed. This tends to clog up the hatch and blades and stop them from turning. I’ve therefore had to improvise with a stick and string to hold the flap up at 45 degrees and allow the cut grass to freely escape through the rear hatch. Even then though, it doesn’t take much for the grass to clog up the rear hatch.My mower also broke down after not a lot of use, which was disappointing. I was mowing the lawn as per normal, and the motor cut out upon hitting a moderately sized tuft of grass (also normal), yet it wouldn’t start again (not normal). I tried swapping the batteries over, putting in freshly charged batteries, unplugging and replugging the key, etc, but nothing I tried enabled it to restart. I had to return it under warranty to Sydney Tools where I bought it.I had to wait 2-3 months to get it back, from memory, which was rather inconvenient, and the Deutscher was put back to work. Allegedly they fixed the fault, then tested it, but upon testing the drive-belt gave up. This surprised me, given I’d only used the mower a handful of times, and it didn’t inspire confidence in the mower's robustness. And it meant I had to wait longer for DeWalt to get the parts in and repair it. I also enquired a few times as to what the original fault was, and was promised a call back (Sydney Tools had to call DeWalt to find out), but I never received the call back.There are some things I like about the mower. The main body is made of steel, which should make it more durable than plastic, though this comes at the cost of extra weight. It’s also pretty quick and easy to fold up the handle, and has a couple of handles, so it’s quite transportable, albeit fairly heavy at 26 kg. I notice that other reviewers have criticised it’s manoeuvrability, though I find it okay. It’s easy to change the cutting height, and the available heights are okay (I usually cut on level 2 or 3). And of course you’ve got the usual advantages over a petrol tool: no fossil fuel consumption, no fumes, no greenhouse gas emissions, quieter operation, easier start.Overall, I’m glad I have a tool that enables me to mow our large lawn without burning fossil fuels, but I’m a little disappointed with the mower's performance. I’m not sure I can recommend it. I hope DeWalt will develop an improved model.
