Worx 2 x 20V Battery-Powered Lawn Mower Review

Worx 2 x 20V Battery-Powered Lawn Mower Offers Quiet Operation and Budget-Friendly Price

When we tested 24 total mowers in our recent Best Gas Mower and Best Battery-Powered Mower comparison reviews, we had a wide range of expectations. One of the fun things about testing tools side by side is that sometimes we see surprises. The Worx 2 x 20V battery-powered lawn mower was one of those that performed better than we expected and improves over previous models.

Pros

• Light and nimble
• Visible battery gauge
• Excellent battery efficiency
• Nearly an hour of runtime under load
• Quietest mower in shootout at 74 dB(A)
• Best value rating out of all cordless push mowers

Cons

• Feels a bit flimsier than other models

Performance

Cutting Power

Brushless and some brushed motors use electronics to adjust to changing conditions. For cordless lawn mowers, we often see them raise their blade speeds to compensate as loads increase. The Worx 2 x 20V battery-powered lawn mower ended this phase of our testing in the lower half of our push mowers for cutting power.

Starting at the beginning, we tested every mower’s blade tip speed under no load to find its baseline speed. The Worx mower banged out 2673 RPM with 151 MPH tip speeds with its 19″ blade. That puts it near the bottom, but this is just a baseline test to compare what happens when it has to start working.

With the Worx, we didn’t experience a surge in power when we applied a lighter load. In fact, the Worx dropped to 2542 RPM with 143.6 MPH tip speed. Even though it’s a net loss of speed, Worx was actually holding the 3rd fastest speed in its class at this stage.

We ramped things up after this, applying a heavier load for the next test. Here, we see most battery-powered lawn mowers start to direct more power to the blade. In the push mower group, every other mower gained some speed and power here.

The Worx, on the other hand, didn’t lose much power under a heavier load, but it didn’t ramp up either. It ended the heavy load testing with a 2540 RPM and 143.5 MPH blade tip speed, which was an ever-so-slight decrease. This was the slowest of our cordless push mowers.

The takeaway is that the Worx 2 x 20V battery-powered lawn mower does a fine job on your regular weekly cut. It begins to struggle when the grass gets overgrown, like several of the other value brands.

Cutting Area

If the power of the Worx battery-powered lawn mower left a little something to be desired, it picked up some slack in the cutting area department.

This mower runs on two 20V Worx batteries, totaling 40V max (36V nominal) of power. It also cuts a 19″ swath, which directly affects the area you can cut on one set of charged batteries.

Now that those facts are out in the open, let’s get to the juicy bits. In our testing, the Worx 2 x 20V battery-powered lawn mower ran for nearly an hour (57 minutes) on a regular maintenance load. Walking at a steady 2.5 MPH under these conditions, you can expect the Worx to mow just under 20,000 square feet or 0.46 acres.

The Worx’s battery efficiency proved to be the best of the bunch, cutting 110 square feet for every battery-watt hour.

Noise Level

We also tested all our mowers’ noise levels. Battery power is much quieter than gas power, and any direction you take in the world of electric mowing will take it easier on your ears. But we still wanted to see which was the quietest.

The Worx 2 x 20V battery-powered lawn mower was the quietest out of all 24 mowers we tested. Its 74 dB(A) lead the rest of the pack, and by a considerable margin. The next quietest mowers were the Redback 40V and the Makita 36V mowers, and they registered 77 dB(A).

We don’t like to use the term “whisper quiet” when talking about mowers – because that’s ridiculous – but the Worx battery-powered mower is about as close to that as you’re going to get.

Feature Set

Steel Deck

The Worx mower uses a steel deck in its construction. We prefer this over plastic decks for durability’s sake even though it adds some weight to a mower you’ll have to push around.

However, we still found the Worx battery-powered lawn mower to have a nimble, lightweight feel to it. It weighs in at just under 67 lbs, so taking corners is really pretty simple.

Height Adjustment and Range

The Worx battery-powered lawn mower features a single-point height adjustment. Rather than having to adjust your cutting height at each wheel like you would in a 4-point setup, you only need to make one adjustment, and boom, you’re ready to cut your grass from anywhere between 1.5″ to 4.25″.

We like single-point height adjustments for their convenience, but there’s is sometimes a downside that comes with them, and we’ve seen it here. The single point can create a flimsiness at the wheel where the adjustment is. With the Worx mower, it doesn’t feel like the wheel is going to break off or anything, but we did notice a slight dip at the wheel with the height adjustment.

Handle Positions

Curiously, the Worx battery-powered lawn mower model only has one handle position to choose from. Most of the mowers we tested included 3 positions, which are helpful for folks of different heights.

The handle has the capability of being folded over for vertical storage as well, though we found that it wasn’t particularly easy to accomplish.

Discharge Options

You’ve got all of the classic mowing options with the Worx 2x20V: mulching, bagging, and side discharge.

Additional Features

• Battery gauge on the deck

Value

The Worx 2 x 20V battery-powered lawn mower won the value competition in the push mower division. The kit – which includes the mower, two 5.0Ah batteries, and a charger – retails for $319. It also comes with a 3-year warranty.

But, aside from a great price, the Worx Power Share System seems to be continually growing. Getting into this mower means that you can also use the Power Share batteries with other Worx OPE tools, like their new chainsaw.

The same battery work in their 20V max home improvement tools, like the SwitchDriver. Ultimately, the Worx battery platform is a good DIY platform to get onto.

The Bottom Line

Not gonna lie, if you like to let your yard get out of control for a week or two, the Worx 2 x 20V battery-powered lawn mower probably isn’t the mower for you. It struggles a bit in the power and torque department. However, if you’re the type that likes to keep your yard in good shape all the time, this mower’s runtime, noise level, and price tag all kind of rule.
