Worx WG771 56V Li-ion Cordless Mower Review
The Worx WG771 is a cordless lawn mower with two 56 voltage batteries, which makes it really powerful. However, the biggest selling point, at least for me, is the caster front wheels. These wheels make the relatively large mower very easy to handle. The mower have several other interesting features like adjustable cutting height, sturdy steel cutting deck, and a battery indictor.
- 56 Volt Lithium-ion battery.
- 19-inch cutting width.
- Steel cutting deck.
- Adjustable cutting height.
- Lockable caster wheels.
- Cuts up to 9,400 sq. ft. in one charge.

Worx WG771 review
There are two reasons why the Worx WG771 is a very interesting lawn mower. The first reason are the front caster wheels that allow you to maneuver this relative large mower with ease. The second reason is the 56 volt Lithium-ion batteries, which makes this mower very powerful compared to most other cordless mowers.
Before we take a closer look at these two features, let us have a quick look at the mower in general. The Worx WG771 has a 19-inch steel cutting deck, which has a nice light grey metallic finish. Overall, the mower appears very sturdy and well built.
The handle is made of aluminum and can be adjusted in height at your convenience with a touch of a button. The handlebars can also be fully collapsed over the mower to minimize the storage space needed. You can also store the mower standing up.
The lawn mower comes almost fully assembled. You literally only need to unfold the handle and insert a bolt on each side before you tighten the bolts. You only need basic tools. You are now ready to go when the two batteries are fully charged.
The mower is also very easy to use, but if you still find yourself stuck and can’t figure out how the mower works, just have a look at the manual. The manual is very good and is full of detailed pictures.
One of the first thing I did were to top up the two removable 56 volt Lithium-ion batteries (2.5 Ah) that comes with the mower. I wanted to have two full batteries to be able to check the Worx’s WG771 battery performance when it comes to endurance and power.
Unfortunately, you only get one charger that can only charge a battery at the time. This is a bit annoying when it takes a couple of hours to charge a battery. However, on the positive side, you can use the lawn mower with only one battery inserted.
If you have other tools from Worx that uses 56 volt batteries as well, you can use these batteries with the mower. However, the greatest benefit would be that you most likely have two chargers to cut the recharging time in half.
The 56 volt batteries were one of the reason I got excited and interested in just this lawn mower. Most cordless lawn mowers have batteries with a lower voltage rating, such as 40, 36 and as low as 24. A general rule when it comes to cordless power tools are that the more voltage the batteries have the more power they have. As you might understand, I expected this WG771 mower to be powerful.
Before I started to mow, I had about 1/5 acre of fairly high and lush grass (roughly 4 inches) so I was curious if the Worx WG771 could handle this without any trouble. I was even more curious to see if I could mow the whole lawn in one go without recharging the batteries. Worx claims the mower can cut up to 9,400 sq. ft. per charge, so theoretically I shouldn’t have a problem with 1/5 acre (8700 sq. ft.). However, you never know what kind of conditions (grass type, length) the mower was tested on.
Let us skip ahead and have a look at the battery performance. I managed to cut my 1/5 acres without any problems. When I were finished the battery level was down to the last bar (25%), so I bet you can manage to cut up to 9,400 sq. ft. as Worx claims. I mowed my lawn with the “TURBO” selection, which increases the RPMs, but sacrifices some endurance. The other selection you can make is called “ECO” which does the opposite, increases the endurance but decreases the RPMs. If you are not sure how large your lawn is, the mower runtime with full batteries is about 40 minutes.
The Intellicut technology that controls both the “TURBO” and “ECO” settings, but it also ensures that the mower gets more torque when it is needed. However, after using this lawn mower for a while I can’t really say I notice much difference between the two settings when it comes to battery endurance or performance. To be honest, the differences between the two settings are so minimal that I just leave it in “TURBO”.
Adjusting cutting height
Before I started to cut the lawn, I adjusted the cutting height to 2 ½ inch which means the mower needed to cut off up to 1 ½ inch of grass. The mower let you choose between 7 different cutting heights, ranging from 1 ¼ inches (30mm, 3cm) to 4 inches (100mm, 10cm).
The cutting height can be easily adjusted with the lever on the left hand side for the rear wheels. While you need to set each front wheel individually, but this is also easily done by a lever for each.
Cutting and maneuvering
The Worx WG771 did not struggle even with the tougher parts, where the grass was probably closer to 5 inches and parts of my lawn where weeds have claimed back their old territory. I am very pleased with the power of this cordless mower.
After using the Worx WG771 for a few weeks, I am still amazed with how well it cuts and its power. Can it compete with a gas mower? No, but it comes close. Is the Worx WG771 the most powerful cordless mower I have tested? Yes! To this date, I have not tested a more powerful cordless mower.
The caster wheels is the second reason I was really excited about this mower. The caster front wheel swivel 360 degrees and let you more easily turn the relatively large mower. The front wheels allow you to turn the mower on the spot, without tilting the front wheels off the ground as you would with a “normal” lawn mower. I promise you, mowing between pots, chairs, or other obstacles you might find on your lawn has never been easier. I really love the caster wheels and how they give me superior maneuverability.
There are a few scenarios were the caster wheels are not optimal. For example, if you are mowing the side of a hill/incline going across (not up and down the incline) and if you are just doing long straights. In these scenarios, you can lock the cast wheels so they will work just like normal fixed wheels. This is easily done by flipping the knob over on each front wheel.
The mower is also light to push, thanks to the 7” front wheels and 10” rear wheels. The mower rolls easily over any uneven or rough patches of the lawn.
The Worx WG771 let you either mulch, bag, or discharge the clippings. There is not much to say about the side discharging the clippings function. It works well.
Bagging the clippings works also well. The bag is easy to attach and detach, quick and easy. The mower throw the clippings all the way back in the bag and the bag fills up without any issues. However, I wish the bag would be a bit larger. The capacity of 1.4 bushels means it fills up quite quickly.
With the mulching capability, I am very pleased. The cutting blade that comes with the mower has a dual edge, which Worx calls “NutriCut”. This blade cuts up the grass clippings to fine small particles. The small pieces of grass left behind the mower are even distributed and quickly disappears down into the lawn.
Comparison to other similar mowers.
So how is the Worx WG771 performing compared to other similar sized cordless mowers? A natural place to start is to look at the almost identical Worx WG772.
The WG772 is basically the same lawn mower, but it doesn’t have the caster front wheels. If you don’t need to maneuver around objects and the lawn let you cut in nice long straights, I think the WG772 is an excellent choice.
Another good candidate is the Greenworks 25302 (read my full review here). What makes the Greenworks 25302 G-Max different from other lawn mowers, are the two cutting blades, which are driven by a motor each. This is supposed to make the mower more energy efficient and squeeze more endurance out of the two 40V batteries (2 Ah and 4 Ah) it comes with. The Greenworks can mow considerably more on one charge than the WG771, with its impressive 70 minutes run time .
The last mower I have compared the Worx WG771 with is the Black & Decker CM1936 (read my full review here). The B&D CM1936 is a solid workhorse with great endurance thanks to the 36V lead acid battery. However, the battery pack makes it quite heavy. This makes the mower best suited for lawns with few inclines. Note that the lead acid battery needs as much as 12 hours to be fully recharged.
Between these mowers, my preference would be the Worx WG771 for sure. The second place is tied between the WG772 and the Greenworks 25302. Last comes the B&D CM1936, mainly due to its weight.

This is one of the Worx WG771 biggest problems, it is simply too expensive. Well, at least that is my opinion. However, the caster wheels makes it unique and makes it hard to compare against other cordless mowers. As I mentioned above, if you don’t particularly need the second to none maneuverability you will find a few great cheaper options.
- Superior maneuverability.
- Very powerful.
- Great mulching capability.
- It is expensive.
- Only one battery charger.
