Worx 2 x 20V Battery-Powered Lawn Mower Review

Worx 2 x 20V Battery Powered Lawn Mower Review: Pros & Cons


1) Durable & Reliable : The battery powered lawn mowers are very durable and reliable.

They can last for many years without any problems. You will not have to worry about them breaking down or dying prematurely. (You may need to replace the batteries every now and then though).

2) Easy To Use : There are no complicated controls or buttons to use with this type of machine.

All you have to do is push the start button and it starts up automatically.

3) Low Cost : If you want a low cost, easy to operate, battery powered lawn mower then this is the one for you!

The price tag is only $80 which means that it’s cheaper than buying a regular gas powered lawnmower.

4) Easy Maintenance : Although there are some maintenance requirements like changing the oil and filters, but they’re relatively inexpensive.

For example, you’ll pay around $20-$30 per year for these things. So if you plan on using your machine regularly then it won’t cost much money to maintain it.

5) Portable : This type of machine is portable so you can take it anywhere since its small enough to carry around with you.

You can even store it in your garage when not in use.


1) Slow: Since it runs on batteries then the speed is naturally going to be slow.

If you want a quick moving lawnmower then you’ll have to stick with the old-fashioned style since battery technology hasn’t improved that yet!

2) Only Cuts Grass : This machine only cuts grass.

It can’t cut other things like leaves or flowers which some people may require.

3) Noisier : Since it operates on batteries then it’s also going to be a bit noisier than gas powered lawnmowers.

If you value peace and quiet whilst working then this isn’t the type of machine for you.

4) Recharge Time : The recharging time is quite long so if you have a large yard then you’ll need to make sure that you take enough breaks between each session.

5) Still Expensive : Although the up keep and operational costs are low, but the initial outlay is expensive.

You’ll need to purchase the lawnmower itself which will set you back around $200.

6) Not As Powerful: Due to it being a battery powered lawnmower, it just doesn’t have the cutting power that gas mowers do.

Taller grass will still clog up the machine and long grass may require you to go over the same piece of lawn several times.

How Does The Worx WG779 Compare Against Other Brands?

The Worx is a good battery lawnmower but it’s not the best. There are a few other brands that you can choose from which are cheaper and have more positive reviews. These include:

Greenworks Pro ML8000 : The lawnmower has an aluminium deck with a powerful 160cc engine. It can cut up to 8000sqft of grass on one full charge and can mulch, rear bag and discharge with ease. There is also a power button which increases the runtime by 70% for finer cutting and mulching. As an additional feature, the machine also has a battery level indicator so that you’ll always know how much power you have left.

The Greenworks Pro is slightly more expensive but can accommodate larger gardens.

Toro Cordless mulching mower : The Toro cordless lawnmower combines the light weight and convenience of a battery powered machine with the power of a gasoline engine. Like the Greenworks Pro, it has a long lasting battery which gives it an impressive runtime of up to 45 minutes on a single charge. It’s also very well balanced with easy push handle and comfortable grip. The only downside is that the machine is heavier than most cordless mowers at 54lbs due to having a larger engine inside.

Husqvarna Automower : This is the closest thing you’re going to get to a robot lawnmower. The Husqvarna Automower doesn’t require anyone to drive it. You just place it in your backyard, define a perimeter and set it going. It’s completely automatic.

You can set it to navigate around your yard at certain times or even at random and it’ll recharge its batteries when necessary. This is the most expensive option but if you want a completely hands off experience then this may be the best lawn mower for you.

Lawn Mower Maintenance And Care Guide

In this section we’re going to talk you through all the basic lawn mower maintenance tasks that you need to be carried out on a regular basis. We’re also going to look at some of the more complex procedures that require a little more skill and effort.

Checking And Changing The Oil

Changing the oil is one of the simplest yard care tasks that you can perform. It also needs to be done on a regular basis in order to ensure that your mower’s engine runs smoothly and efficiently. Most mower engines use what is known as ‘dino’ oil (otherwise known as petroleum or conventional oil). There are also synthetic oils which generally speaking are better but they tend to be more expensive.

Therefore you need to decide which is best for you given your budget and the type of yard that you have.

The first step is to make sure that you’ve gathered all the tools and equipment that you’re going to need before you start otherwise you’ll end up having to come back later and that’s going to end up wasting time and possibly ruining your lawn mower. So before you do anything turn off the engine, get your tools together and then drain the oil.

The engine needs to be cooled down before you can safely work on it. So let it run until it’s cooled right down, make sure that you put the deck in the up position (so the blades don’t spin) and cover the engine with a cloth or something similar (like an old coat) just in case it splutters or spits at you. The last thing you want is for hot oil to spray on you and burn!

Next remove the oil fill cap. Some people like to use an oil pan or jug to catch the old oil as it drains out. Personally I’ve never had a problem with the old oil just dripping onto the ground but if you feel more comfortable with using a container to catch the old oil then go ahead. The next step is to remove the drain bolt on the bottom of the engine.

Most mower engines (like the one in the photo above) use a hexagonal bolt than can be removed with an allen key or a socket. Other mower engines have a simple bolt that’s easy to spot and remove.

Once you’ve removed the bolt, allow the oil to drain completely. Some engines hold quite a bit of oil so you may have to tip the mower on its side so gravity helps the oil flow out more quickly. You can then replace the bolt once all the oil has drained out.

The next step is to remove the oil fill cap on the top of the engine (if your mower has one). Use an oil container (like an old milk jug) and pour about a cup of oil into it. Now use a funnel to pour the oil very slowly into the fill cap opening until you see it slowly start to come out again (you’ll hear it). At this point you can remove the funnel and just allow the oil to drain out onto the ground (or into your container).

This process of filling and emptying is repeated several times until no more oil comes out of the fill hole. This ensures that all the old oil has been drained out and replaced with fresh clean oil.

Once you’re satisfied that all the old oil has been replaced with new then you can replace the fill cap (make sure its nice and tight) and also replace the bolt at the bottom of the mower engine. Now just wait around 15 – 20 minutes for the oil to get pumped through and into all the internal parts of the engine.

Once the waiting time is over you can start the engine and check for any leaks. If everything seems okay then you’re done. If not you might have to repeat the process.

The oil needs to be changed on your mower every month or two during the hotter parts of the year and maybe four times a year during the colder months (depending on how often you use your mower).

Always remember to dispose of your old oil properly. You don’t want to just throw it in the trash or pour it on the ground as it can contaminate the soil and water tables. Take it to your local recycling center and they’ll usually dispose of it for you.

Always follow the manufacturer’s instructions on the oil container. Some oil needs to be heated before use, some needs to have a certain weight or grade and others have no specific requirements at all. Always read the label before use!

If it’s been a year since you replaced your mower blades then they probably need to be changed too. Blades get dull over time and can damage not only the lawn but also the engine.

Always store your mower in a dry place that’s free of critters who might want to have a nibble on it (especially rodents and insects). A good storage spot is in your garage or a shed. Just ensure that the engine is fully cooled before you store it and clean off any grass clippings first so that they don’t get damp and cause corrosion.

Maintaining your mower isn’t too difficult, just make sure that you do it on a regular basis to keep your lawn looking great and your engine running at its best.
