My Overview of the DEWALT Twin 18v Lawn Mower
The DEWALT DCMW564RN XR 18v Brushless Lawn Mower was first launched in 2017/18 I purchased mine in September 2023.
This mower is a Push Mower. No propulsion. It takes two 18v batteries to run it at 36v.
If using two 18v, 5ah batteries with the DCMW564RE/RN then you have 36v at 2.5ah and can mow for approx 15 to 20mins, depending on what you are mowing.
I use the DCMW564RN with two 9ah Flexvolt batteries, which allows me to mow for almost an hour. This is on a well-kept lawn that isn’t overgrown or wet.
Dewalt seems to have made a really sturdy mower here with this one. The build quality is excellent.
The Good
Battery Life
Approx one hour with 2 x 54v Flexvolt batteries
Battery Costs
Being able to use any 18v 5ah or 54v battery saves a ton of money.
Build Quality
The tough plastics and metal deck really make this mower tough.
Carry Handles Front and Rear
Two handles make it so much easier to lift in and out of a vehicle.
The Bad
Squeeky Wheels
My mower has annoyingly squeaky wheels. Even after oiling them.
The Cost: £400 via eBay (New in 2023)
My Previous Cordless Lawn Mower
My previous lawn mower was a Bosch 36v, single battery cordless mower. That was all plastic, heavy and lasted me 10 years before I replaced it with the Dewalt.
What made me choose The DEWALT DCMW564RN XR?
- Batteries!
My first priority when looking for a new cordless mower was the batteries! I was sick and tired of how long it took to charge the Bosch 36v batteries. Furthermore, those 4ah batteries were over £200 each!
I needed a power source that didn’t require yet more chargers and batteries. Multiple power systems are a total pain in the backside to manage, so simplicity was crucial here.
- Mowing Time!
When we moved home, our garden size tripled to 240m Square.
My previous Bosch 36v, 36cm wide Bosch mower now needed recharging two or three times to cut my lawn once. It would last for approx 14 minutes per 36v battery. I needed a mower that was wider and faster and could mow for a lot longer!
Some Nerd Mowing Maths
My previous Bosch mower had a 36cm cutting width. It’s very narrow for such an average lawn. Making the DEWALT DCMW564RN XR 1/3rd wider at 48cm.
With my Bosch mower, I had to make a minimum of 20 passes up and down my lawn to cut it all. Often recharging the battery after 10 passes.
Now it takes only 15 passes back and forth. Although I always mow it twice, the stripes left by the DEWALT DCMW564RN XR are wider and nicer.
