WORX WG779 40V Review: Battery Hog or Lawn Care Hero?

The WORX WG779 40V cordless lawn mower costs $200, and user reviews have been all over the place. Some people gave it a lower 3.4 out of 5 stars on Best Buy, while others rated it a solid 4.4 out of 5 stars on Target. I decided to try it out myself and see if this battery-powered mower lives up to the hype.

When people talk about cordless mowers, the main concern boils down to battery life compared to cutting strength. The WORX 40V mower says it can cover up to 1/8 acre, or about 5445 square feet, with one charge. This seems impressive for a battery-powered lawn mower. Still even though users often love how easy it is to use (4.6 rating), plenty of them feel let down by how long the battery lasts.

Over the last three months, I’ve been running the WORX WG779 through various tests in my yard. I’ve looked at everything from eco mode and turbo mode to how well it handles mulching. It has some standout qualities, like a 6-position cutting height adjustment that ranges from 1.5 to 3.5 inches. Its compact design folds up making storage simple.

In this WORX WG779 review, I’ll give an honest breakdown of my experience with this cordless mower. Is it the perfect choice for small yards, or just another device that leaves you stuck with a dead battery halfway through mowing?

WORX WG779 40V Specifications and What Comes in the Box

When I opened the box of my WORX WG779 40V, I found a well-organized lawn mower that was easy to assemble and came with all the parts needed to start mowing right away. Unlike some power tools that cut corners with extras, this one includes everything necessary to handle different cutting tasks.

Battery: 2 x 20V 4.0Ah Lithium-Ion

The mower gets its power from a dual battery setup. WORX doesn’t rely on a single 40V battery. Instead, it uses two 20V 4.0Ah batteries through their Power Share platform to combine into 40V power. This system adds versatility since those same batteries can also run on more than 75 other WORX tools.

Every battery comes with a handy 3-LED display that makes it easy to check how much power is left. The lithium-ion design avoids memory effect problems that happen in older batteries so charging it halfway does not harm its lifespan. It takes around 2 hours to charge a battery using the provided charger.

Cutting Width: 14 inches

The WG779 has a 14-inch cutting deck, which offers a good balance between being easy to steer and getting the job done. This width lets the mower fit through tight spots like narrow paths between flower beds or around obstacles, while still covering enough space . Its steel blade cuts and lasts longer compared to the plastic blades found in some other models.

The deck comes with a 6-position height adjustment system. It offers cutting heights between 1.5 and 3.5 inches to handle different grass styles and conditions. A single lever makes height adjustments simple. Some cheaper mowers use separate wheel adjustments, which are harder to manage.

Weight and Size

Without batteries, the mower weighs 29.1 pounds. With both batteries, it weighs 35.9 pounds. Its light weight makes it easy to use for people with varying strength levels. The mower’s compact size measures 29 inches in length, 16 inches in width, and 37.8 inches in height when the handle is extended.

When you fold it to store, the handle drops down lowering the mower’s height to 13 inches. This design lets you stand it upright against a wall or slide it under a workbench. That’s a big help in saving space in smaller garages or sheds.

What’s Included: Mulching Plug, Grass Bag, Charger

The package comes with a charger that can load up both batteries at the same time. It also includes a 1.2-bushel grass bag, which can hold about 42 liters of clippings. This bag has an indicator to show when it’s full so you avoid overfilling. Instead of using the bag, you can pop in the mulching plug, which makes the mower return the trimmed grass to the lawn as a kind of natural fertilizer rather than collecting it.

Assembly and First Thoughts

Putting together my new WORX WG779 40V was a lot easier than the other lawn tools I’ve bought before. When I unpacked the box, I pulled out the mower, two 20V batteries, a dual charger, a piece for mulching, and a bag to collect grass. It’s obvious WORX focused on making assembly simple and easy to use.

Time to Unbox and Assemble

First impressions count, and the WG779 made a strong start with done packaging. The box arrived in a compact form to cut down on shipping space. Inside, all parts were well-arranged and free from damage. Setting it up and getting it ready to mow took under five minutes. This is great news if you dislike setups that feel like solving a puzzle.

Even so, I found the included instructions helpful. They leaned more on pictures than words, which worked fine. The assembly steps covered attaching the handlebar putting together the grass bag, and getting the mower ready to use.

Setting It Up With No Tools

, putting everything together does not need any tools at all. This design without tools made it easy. All I had to do was unfold the handles and lock them using the orange fasteners that came with it. It lets you pick from two height options on the lower handle to suit your needs.

, the handle assembly was so straightforward that I glanced at the instructions. Every part snapped into place with a satisfying click showing how much thought WORX put into making the worx lawn mower 40V simple to use.

Charging the Battery and Setting It Up

As expected, the batteries came uncharged. WORX suggests charging both batteries to full capacity at the same time before using them for the first time. You can use the included dual-port charger to do this. Each battery takes two hours to charge.

Sliding the batteries into place was simple. You just push them into their slots until you hear a click. The mower works if both batteries are inserted. This two-battery setup ensures a steady flow of power. However, if one battery is charged less, the mower will perform to the level of the weaker battery.

How It Works After 3 Months

I spent the summer and part of fall putting the WORX WG779 40V to the test, which gave me a solid feel for how it performs in real life under different situations.

Eco and Turbo Modes: Which Works Best?

The IntelliCut™ technology came in handy during my mowing. Most of the time, I stuck with Eco mode to handle routine lawn cuts. This approach stretched the battery life by a lot. When I faced thicker or taller grass though, Turbo mode was the go-to option. This feature also manages torque by tweaking it to match the grass. It saves energy on easy patches while ramping up power when the job gets tougher.

How It Handles Different Grass Types

Even though it’s small, this mower dealt with various grass types well. The 14-inch cutting deck did a great job on my usual lawn, but I did have to go over thicker spots twice. During testing, I used the height adjustment system, which ranges from 1.5 to 3.5 inches, to handle everything from tall overgrown grass to routine trimming.

Battery Life in Real Situations

Battery life depended on how intense the mowing conditions were. Most of the time, I got the promised 5,000 square feet per charge. However, switching to Turbo mode cut down that range quite a bit. Even with that, I never ran out of battery power while working.

Managing Hills and Uneven Ground

This mower, at just under 30 pounds, felt agile when used on slopes. But on uneven ground, its light build (weighing 29.1lbs) could sometimes cause cuts to look a bit patchy. The plastic wheels don’t cushion bumps well, which made it struggle on rougher patches.

Comparing Noise to Gas Mowers

With noise levels of about 88 decibels, this cordless mower operates much quieter than gas-powered models. WORX states that thanks to their “Mute technology,” it is “audible from 10m,” which makes it a better option for mowing early mornings without waking the whole neighborhood.

Its Design, Storage Needs, and Upkeep

One feature that stands out about the WORX WG779 40V is its smart storage design. It solves the common problem of finding space in small storage areas.

Foldable Handle and Easy Storage

The mower’s handle folds in two spots, so it can lie flat when needed. This smart design lets me store it upright against a wall or slide it under a workspace in my garage. I think the biggest benefit of the folding handle is how much room it frees up. Weighing just 29.1 pounds, I can pick it up and even place it on a shelf if I have to. The central carry handle is placed so well that moving the mower between the lawn and storage is much easier than I expected.

Cleaning the Deck and Grass Bag

Keeping this model clean is pretty simple. I just tip the mower onto its side and use a firm hand brush to clear out grass from the base, around the blade, and off the wheels. The manual says you should take out the safety key before doing any kind of maintenance. The grass bag, which has soft cloth sides combined with a sturdy top, folds flat to store. It also has a handy flap that lets you know when the bag is full. WORX advises you to clean the deck every time after mowing if the grass is damp.

Build Quality and Durability Over Time

During my three months of testing, I noticed the build quality held up well. The metal blade stays sharp over time, though WORX advises users to replace it after 50 hours of mowing or two years, depending on which comes sooner. The overall construction seems fair for what it costs. The handle has a soft foam cover that offers some comfort while using it, though it does not feel as nice as the rubber-coated ones on pricier models.

Final Thoughts

After using the WORX WG779 40V mower for three months, I got some mixed outcomes to report. Its dual 20V battery setup offers enough power to handle small or medium lawns, but it does not match up to the strength of gas-powered mowers. The biggest drawback so far has been the battery life. In Eco mode, it manages to cut my 5,000-square-foot yard on one charge, but Turbo mode drains the power much quicker than promised.

This mower seems to shine more when it comes to ease of use instead of sheer power. Its light build makes it super easy to move around objects, unlike heavier gas models. On top of that, the fold-up storage design comes in handy to save space. It can be stored against a garage wall, which is a big plus if you are short on room.

The mower handles regular cutting well, but it struggles a bit with taller grass even with the Turbo mode. The mulching feature does its job, though it is not as good as some pricier models. The 14-inch cutting path manages to balance being easy to move around and still getting decent coverage.

At $200, it’s a fair deal if you expect it to handle lighter jobs. If you have a big yard or often deal with thick or wet grass, the battery will let you down. Its tool-free setup and low-maintenance design make it appealing to new homeowners or anyone who’s tired of dealing with gas mowers.

Key Points

Testing this mower for 3 months gave me these main observations:

• Battery runtime depends on the mode you use – Eco mode meets the promised 5,000 square foot coverage, but Turbo mode burns through the battery much faster than expected.

• Works best in tiny yards under 1/8 acre – The 14-inch cutting deck and dual 20V battery system handle routine yard work well but can have trouble with very tall or thick grass.
• Super easy to store – It weighs 29 pounds, and the handles fold. You can stand it upright against a wall, which saves a ton of space in garages that are short on room.
• Takes under 5 minutes to set up without any tools – Unlike gas mowers, its assembly doesn’t need tools. You just click the parts together, and it’s good to go.
• Way quieter than gas-powered mowers – At just 88 decibels, you can cut the lawn in the early hours without waking up your neighbors. It’s great for areas with lots of nearby homes.

The WORX WG779 40V deserves its nickname as the “small yard hero” because it offers convenience and effortless use. This is ideal for homeowners who prefer ease over strong cutting power. But for bigger lawns or grass that grows thick and fast more powerful mowers might work better.
