Features To Consider With Cordless Lawn Mowers
The power of the lawn mower comes from the motor and the voltage. The better the motor, the more efficient it will be at cutting your grass and make it easier for you to get the job done swiftly. Your choice can also be determined by how often you cut your grass. If you like to stay on top of keeping your grass at a manageable level, you may not need much power. However, you may still encounter issues when you leave the grass to grow over winter.
The longer the battery life, the more you will be able to mow at any one time. Longer and more powerful batteries ate excellent for larger lawns, but they are also useful for small and medium lawns if you want to make the investment. You can also find options with replacement batteries to get the lawn mowed entirely in one session. Most lawn mower batteries will last between 40 minutes and 120 minutes, although this can vary depending on the length of the grass, whether it is wet or not, the age of the battery, and the condition of the blades.
Heavy mowers can be difficult to maneuver around the yard, so a lightweight option could be useful and easy to push if you will struggle with that. However, a mower that is too lightweight could not handle more demanding mowing tasks, and it could also affect the durability. With this in mind, it’s vital to find the right balance between maneuverability and durability. There is also the issue of portability, especially if you use the battery powered lawn mower for commercial means.
Cutting Height Options
Cutting height can give you the perfect control and customization you need for your lawn. It will allow you to ensure your garden looks lush and green while also making it easy to manage and ensuring that the grass grows healthily. There are a wide range of cutting height options available, and all of them come with a simple handle that is easy to operate. If you’re not aware, the height of the grass should change depending on the season. For example, cut it slightly long in Spring then gradually lower as Spring goes on.
The run time will be determined by several factors, including the battery charge, age of the battery, and the condition of the lawn. If the grass is too long, then it will demand more effort from the motor, and this will cause the battery to drain quicker. Furthermore, as the battery ages, it will not hold as consistent of a charge, which could drastically affect the overall runtime.
If the battery runs down, you can at least charge it, but the mower you choose could be impacted by the charge time. Typically lawn mower batteries can charge in as quickly as an hour, and this is an excellent option if you’re looking for convenience, especially if you do not have a spare battery available. For larger lawns, this could be essential, as it will allow you to complete the whole lawn within a single day, even if it means you need to wait for an hour in between to ensure that you can get back to it as soon as possible.
Maintaining your lawn mower will ensure that you get as many years out of it as possible. Proper maintenance includes many things, including cleaning or changing the blades, charging the battery, and tighten the hardware. Cordless mowers typically require less maintenance compared to other options, so you may not need to do much. Despite this, it is still worth taking proper care of your mower to guarantee that it lasts as long as possible.
The deck size determines how wide of a range you can cut in one run. The larger the deck, the more grass you can cut at any time. A wider deck can minimize how long you will need to cut the grass for. However, if you have an unusually shaped lawn with lots of nooks and crannies, this could make it more frustrating. When purchasing your mower, consider the size and shape of your lawn to decide what deck size is most appropriate for you.
Ease Of Use
A cordless lawn mower is not the most complicated thing in the world to use, but you should consider things such as how simple it is to start to prevent any issues before you get started. Push button starts are the best way and it relieves the issue with the pull cord start of older mower models. You can also consider the ergonomics of the handle to ensure comfort, as well as how easy it is to adjust the deck height, empty the grass bag, and install the battery.
From mulching capabilities to automatic bagging, there are a range of features you can find with a cordless electric lawn mower. This can also include adjustable cutting height, multiple batteries, a battery level indicator, or easy maneuverability. You know what you need more than we do, so keep an eye out for the features that will make your lawn mowing experience as easy as possible.
We don’t need to tell you that lawn mowers can be dangerous if there are not used properly, but cordless lawn mowers, especially those with a lithium-ion battery, provide a broad range of safety features and designs that guarantee it won’t overheat or overload, as well as using a high quality to prevent blocked or broken blades.
Cordless Lawn Mower FAQ
Q: Can I cut wet grass with a cordless lawn mower?
While you can cut wet grass with a cordless lawn mower, it is not recommended. Cutting wet grass is tough enough, as the will clump, and this could jam the blades. Furthermore, the moisture could also cause the blades to rust, which affects their quality and cutting ability.
Wet grass is also heavier than dry grass, and this makes it difficult to collect and separate. If your lawn mower uses a collection bag, this will weigh the bag down and while also risking grass sticking the sides, which could cause further blockages that will affect efficiency.
You will also find it is more difficult to cut entirely. Instead of a clean cut, like you get with dry grass, your mower might instead tear the grass from the soil, leaving patches that ruin the overall quality of your lawn. Finally, as cordless lawn mowers operate with batteries, there is a risk of moisture affecting the electrical parts that power the motor which could ruin it and make it unusable. As cordless lawn mowers can be quite an investment, this is another reason that you shouldn’t cut wet grass with a battery lawn mower.
Q: What maintenance does a cordless lawn mower require?
Unlike gas-powered options, cordless electric lawn mowers require hardly any maintenance. You will not need to refill the gas tank to give it power, and there will be less oily discharge to clean to keep it in top condition.
However, just because an electric lawnmower does not require as much maintenance, that doesn’t mean you can ignore fundamental cleaning demands. If you want your cordless electric lawn mower to work at peak performance, you should still make sure to take excellent care of it.
This includes cleaning the blades and removing any grass, dirt, or debris that has solidified. If you have had your mower for a long time, you may also need to replace the blades so it cuts properly. You should also wipe down the exterior, even if you only do so because you want it to look nice while you are mowing. If you leave it for too long, there is a risk of if looking weathered and damaged well before it’s time, and this could affect resale value if you ever upgrade to a more powerful model.
One key fact to remember is to tighten the motor and other hardware. Cordless lawn mowers are powerful, they need to be to cut different types of grass, but this power comes with strong vibration and over time, this can cause components to become loose. Every spring, which is usually the time where you will start mowing again, give your cordless mower a quick audit to make sure that everything works to it’s best potential and you can have the best cordless lawn mowing experience possible.
An electric mower is like other power tools. They are an investment, so taking the utmost care of the exterior and the inner parts will guarantee longevity.
Q: Can I cut long grass with a cordless lawn mower?
Like any lawn mower, corded or not, it is possible to cut long grass when using one. Some cordless lawn mowers are designed specifically for long grass, and this is useful if you live in an area that gets plenty of rain or have grass that grows quicker than you can keep up with.
That being said, grass that is too long will be a struggle for any type of lawn mower. As cordless lawn mowers rely on a battery, this could be a major issue, especially if the battery is close to running out. Trying to cut long grass without ample power could cause problems. If the blades are not spinning quickly enough, it won’t cut as much as it could tear it out, and this can damage the blades and the motor. If you are used to dealing with long grass, this is something to remember, and it’s in your and your mower’s best interests to keep it short and manageable if possible.
It is perhaps better for you to invest in a corded lawn mower if you are dealing with long grass, as the consistent power supply will be better equipped. However, if you do not want a corded mower, then ensure that your battery is fully charged before starting, and invest in a cordless lawn mower that is specifically designed to cut high and thick lawns.
Q: What is the difference between corded and cordless lawn mowers?
The primary and obvious difference between a corded and cordless mower is that one runs on a consistent power supply provided by an outlet (corded) while the other relies on batteries (cordless) to power it.
As corded mowers will run as long as they are plugged in at the socket, you don’t need to worry about using up all the battery in one go, and you can take as long as you like to mow the lawn. However, this will still use up energy which could affect your monthly utility bill.
Conversely, a cordless mower running on batteries will run out eventually, and you’ll need to charge the battery before using it again. This can be inconvenient if you have a larger lawn, and it could take several sessions before you are satisfied. A cordless mower offers increased maneuverability, as you are not restricted by the length of the power cord.
Corded lawn mowers are also cheaper, and may require less maintenance. However, there is also a risk that you could damage the cable if you stretch it too far. Regardless of which option you choose, you will need to resharpen the blades to ensure top-quality performance and longevity.
Q: How long do cordless lawn mowers batteries last?
Cordless lawn mower batteries can last as much as 120 minutes depending on the brand and how old the battery itself is. Over time, you will find that the battery will be less and less effective. This usually occurs after around 6 or 7 years, although it could be longer if you take care of the battery properly.
Because of this, it’s essential that you remember to charge the battery and keep it charged to ensure that you can mow all of your lawn in one session. For larger lawns, this may not be possible, so it is useful to look for a mower than comes with two batteries, allowing you to replace one once the battery has run down.
The best battery lawn mowers can provide a convenient and straightforward solution for keeping your yard in excellent condition. To ensure that you can mow the entirety of your lawn without interruptions, a long-lasting battery that also comes with a replacement is the best option for you. There are a range of mower types available suitable for a variety of lawn sizes so that everybody can find the ideal product for them.
Q: What is a cordless lawn mower?
As the name suggests, and as you can probably deduce, a cordless lawn mower is a lawn mower that operates without a cord. It’s as simple as that. However, that isn’t all that impressive when you look at it with an untrained eye. We’ve had cordless lawn mowers before. Way back when, they were manual versions without a motor that used blades arranged in a cylinder for you to push around the yard. Following that, gas powered lawn mowers didn’t rely on electrical cords, either.
Still, both options were exhausting to use or bad for the environment. This is why electric mowers became popular, but even these had their drawbacks, especially if you had a big backyard to cover. With cordless mowers, you don’t need to worry about this problem. They operate on rechargeable batteries so you can operate them for up to 60 minutes, depending on the brand, without the restraints of the cord length.
Compared to both gas-powered and corded lawn mowers, these are more eco-friendly, as they use less energy and have zero emissions, and they can also be more lightweight, and therefore more easy to maneuver, store, and transport.
