To maintain your garden in the best possible way, there is nothing like using a battery powered weed eater, which will allow you to prune your brambles or clear your undergrowth, for example.
Maintaining the lawn in your garden can be a simple and enjoyable task or it can become a tedious and complex one. It all depends on whether you choose a good weed eater or not. A good weed eater allows you to mow the lawn at your own pace, without having to make many passes and offering good mobility to optimize product performance.
Brush cutters are gardening tools that allow you to reach hard-to-reach areas, such as rough terrain, or to work on dense vegetation that the mower cannot handle.
It is therefore essential to have such a garden tool, which is capable of adapting to any type of terrain and any type of vegetation. But there is a wide choice among string trimmers. Indeed, there are as many different types of land and vegetation as there are different types of weed eaters. You can find a thermal, wheeled, portable, ride-on, backpack or battery powered weed eaters.
Your choice will depend on several criteria: the surface to be treated or cleaned, the type of ground, but also the accessories you wish to have. In this article, we will focus mainly on battery powered weed eaters.
How to choose a battery powered weed eater?
Today, there is a growing global awareness of the need to reduce the carbon footprint, drive more efficient cars and improve the energy efficiency of homes. But there is another way to reduce emissions, and it’s probably a machine waiting for us in our garage. Battery-powered (wireless) weed eaters are enjoying a wave of popularity and as sales increase, manufacturers are improving the technology and features of each new model.
In a world of smartphones and wireless access everywhere, we have become accustomed to moving around wirelessly. So why mow the lawn differently? With a battery powered weed eater, all you have to do is plug in the battery and start the task; it’s a question of whether or not it’s right for the job we’re going to do, or whether we would need other equipment with other features to do it.
However, like all machines, they also have some disadvantages. But despite this, there are still countless parks and gardens where a wireless lawnmower is an excellent, if not an excellent alternative.
In this article, we will give you some tips to help you decide whether to buy a battery powered or wireless string trimmer. However, we must first ask ourselves some questions about what concerns to raise with the seller.
The battery powered weed eater is easy to use
The battery powered weed eater is very handy. With her, there is no need to entrust the task to a professional. A mother can easily indulge in the pleasure of gardening with this easy-to-use tool.
- Freedom of movement
Unlike the wired electric string trimmer, the cordless weed eater does not need to be permanently connected. It has a motor similar to that of an electric drill that can operate independently once charged. In addition, it is lighter than the thermal brush cutter.
- Power with Li-Ion batteries
Equipped with lithium batteries, these new generation weed eaters are durable and have a range of 45 minutes. A time that allows you to cut up to 1500 linear meters of grass.
- No pollution
Motorized string trimmers are noisy and can cause neighborhood disturbances. In addition, as the age of their engine, the smell of gasoline is uncomfortable. There is no noise, however, for battery-powered weed eaters.
- Low maintenance
The motor of a battery-powered weed eater requires no lubrication and requires almost no maintenance.
- Low power consumption
In addition to providing a good price/quality ratio, the battery powered weed eater is very economical.
Advantages of the battery powered weed eater
The main function of the weed eater is to clear weeds and mow grass that is not at the right height. The battery powered or electric cordless string trimmer can be used to maintain areas where the mower cannot operate. These include flower beds, garden borders, sloping grounds, embankments, hedge edges, tree edges, wall bases, etc. It also allows you to do other actions such as finishing the mowing and pruning some plants that are too prolific.
Disadvantages of battery powered weed eaters
The battery powered weed eater works with a rechargeable battery. As a result, its autonomy is limited in time. After a maximum of 1h15 of work, you will have to recharge the battery, even if the work is not yet finished. You will have at least 30 minutes of forced break even if you want to finish the maintenance of your garden as soon as possible. Caution should also be exercised as some poor quality batteries may overheat under heavy use.
As for the battery, it is generally expensive, which increases the cost price. However, the user has to buy a battery in one of these 3 cases. Some devices are supplied without the battery; the used battery must be changed; having a spare battery is very convenient when working on a very large area or on land far from home. It is advisable to share your battery by having several tools from the same brand: brush cutter, drill, hedge cutter,…
Battery powered weed eater has limited power compared to a thermal string trimmer. It should also be noted that they can attack brambles, very dense wild grasses, but they are not recommended for clearing land that has been abandoned for years. Some thermal tooling models are more suitable for this purpose. For ease of use, the battery powered weed eater is a little heavier and slightly more cumbersome than a wired electric string trimmer.
Is a battery powered weed eater a good option for me?
In fact, each user will choose the type of machine that their pocket can afford and that best suits their needs. But there are at least three fundamental reasons for choosing a wireless cutter.
- Mowing area size: Since there is a decrease in performance when the battery loses its charge, wireless weed eaters are best used in small and medium-sized areas, i.e. no more than 2000 square meters.
- Type of terrain: A cutter with a rechargeable battery has a lot of power, but it cannot raise and lower the waves as easily as a cutter that explodes. For this reason, wireless works best on flat ground.
- Lawn height: The blade of a battery mower does not have the same level of torque as a gasoline mower. This means that you cannot handle a dense, tall lawn or weeds as effectively as an exploding lawnmower.
Therefore, if you have a relatively small and flat park or garden and a well-maintained lawn, the best machine to maintain it is a battery-powered lawnmower, with which you can enjoy many seasons of simple and quiet mowing.
Motorization and its energy consumption
A battery powered weed eater is an essential part of gardening equipment. In order for it to meet the needs of sanitation and maintenance, it is important that the motorization is adapted to all types of work. This guide will help you answer the question of how to buy a brushcutter with a better quality/price ratio.
As the device runs on electrical energy, it requires power supply so that the motor can deliver all its power while respecting the sound quality. The proposed model is similar to any household appliance in terms of energy consumption but also in terms of operating design with an on/off button. It is known that it is not necessary to lubricate the motorization of an electric brushcutter.
As for the cutting system, it is direct since the device is associated with the axis of the electric motor located at the bottom of the device. The machine is then adjustable in power according to the type of work to be carried out, knowing that the maximum power is 1.5kW, intended for cutting grass. It is essential to point out that with such power, the brushcutter is neither a noise pollutant nor an air pollutant. It should be noted, however, that for long-distance work, it will be necessary to agree to use an extension cable given the limited length of the appliance’s electrical cable.
Differences with other engines
In terms of energy expenditure – cost of consumption – the battery powered weed eater is much more economical than the one with a thermal motor. This model is also non-polluting. There are no greenhouse gases or fuel odors and it is very quiet. The battery powered string trimmer is lighter than the thermal brushcutter.
Wireless, it does not disturb the user and does not limit the operating distance. It is the ultimate portable tool because it is very handy and has perfect ergonomics. Its power is higher than that of wire brush cutters. Many models of battery powered weed eaters are equipped with metal cutting heads – blades or knives – in addition to the nylon wire cutting head.
Battery-powered engines have two major advantages. First, there are a few brands that offer a unique battery that is compatible with many other gardening and DIY tools (chainsaws, blowers, vacuum cleaners, pruners, drills, screwdrivers, etc.). Secondly, there are multifunctional tools, i.e. a single device delivered with different types of cutting heads (pruner, hedge trimmer, chainsaw, edger, etc.). This is very convenient for gardeners who have different types of maintenance to do.
As already mentioned, depending on the make and/or model of the machine, the batteries can be 12, 24 or 36 V. Some major brands already use batteries of 40 V or even more. Although the power that each battery size can provide depends on other variables, such as the condition of the grass and the design of the mower, a higher voltage battery generally provides more power and a longer operating time. Under the same conditions, the operating times are approximate as follows:
- 12 V battery: 30 to 45 minutes
- 24 V battery: 45 to 75 minutes
- 36 V battery: up to about 90 minutes
The heart of the weed eater is the battery, so that’s where you need to look for power and quality, knowing that a good battery must offer at least 500 recharges.
Most models are equipped with lead acid batteries, others with nickel-cadmium batteries and others with lithium-ion batteries. Nickel-cadmium is the least recommended because it does not retain the charge like any other and stops working effectively when the charge dissipates.
As for the choice between lead-acid and lithium-ion batteries, it is a little more complicated. One of the main advantages of lithium-ion batteries is that they can provide more power in a lighter package. Another advantage is that they can be recharged much faster: only 60 minutes compared to at least 12 hours for lead acid batteries. This can be important if our field is large enough to require a recharge in the middle of the cutting task. Otherwise, the 12 hours required to charge a lead-acid battery should not be a problem.
Earlier, we mentioned other technological advantages of universal batteries, so we mention them again at that time. So if we have, or plan to acquire, other wireless tools that can use the same battery as our weed eater, then it will be very convenient to choose a lithium-ion battery mower.
On the other hand, some models have fixed batteries and others have batteries that can be removed for recharging. The choice is at our discretion, although many users prefer to have a spare battery always charged for use at the right time. If this is the case, we should opt for models with removable batteries.
Grass clipping waste disposal options
Basically, there are three: shredding, bagging, and lateral/rear evacuation. Some models combine two of these options on the same machine; other more expensive models combine all three options.
The cutting width and height are important factors in our choice. Although the cutting height depends on the type of grass we use and the time of year, the cutting width influences the handling of the machine.
Condition for using a battery powered weed eater
Before using your battery-powered weed eater, make sure you wear the proper clothing and protective equipment: clothing close to the body or put on coveralls, thick gloves, protective helmet, safety glasses, work shoes or sturdy shoes. Check that all the components of your tool are firmly assembled. A check is carried out to determine if there are any loose screws or incorrectly adjusted parts.
Make sure that no one is within 15 metres of your work area. Pets and moving solid objects (stones, etc.) should also be kept away. First stop the unit and make sure the motor stops running before checking the cutter head.
Maintenance of the weed eater
To guarantee the lifetime of each device, our price comparison recommends that you do not neglect its maintenance, as this type of device still represents an investment for a household. It is important to know that it is essential to regularly clean your device before and after each use.
In the case of an electric weed eater, it is not necessary to lubricate the entire motorization. If you choose a wheel cutter, also clean the wheels after each use with a strong enough water jet or if possible with a high-pressure cleaner to get rid of any vegetation residue. Finally, be aware that it will be essential to sharpen your brushcutter’s blades annually to ensure a good cut for grass and edges.
Can we know in advance the battery life?
The battery of a weed eater has a range from 30 minutes to 90 minutes. This autonomy depends on the amperage expressed in Ampere-hours (Ah) which varies between 1.3 and 5 Ah. Autonomy is indicated by the sellers (see the product sheets on the e-commerce sites or store explanatory panels) from the manufacturers’ data, but poor quality models do not retain their autonomy for long. This decreases over time.
How do I remove the battery from my weed eater?
Each device adopts an unlocking lever located near the battery, simply pull or rotate it (depending on the model) to remove the battery.
Can I use other cutting heads on my weed eater?
It is best to use only the cutting heads recommended by the manufacturer. Using other wires or blades of different sizes can cause severe damage to your tool.
