Which lawn mower is better mechanical or electric?
Hand lawn mower. Worth Buying? And how to choose? on the Nedvio website
The main criterion for choosing a lawn mower is the size of the lawn. Depending on the lawn area, the decision is already made whether to buy a large, expensive and powerful device or maybe it’s worth choosing an easier and cheaper mower.
What are we actually talking about?? That a hand lawn mower is well suited to smaller lawns. It doesn’t need electricity or diesel or gasoline. all it needs is for you to just roll it across the lawn.
How a hand lawn mower works?
The main element in mechanical lawn mowers is the cutting mechanism, which rotates as the unit moves. It can be drum or cylindrical. Structurally they do not differ much from each other. Yes, and they are about the same in terms of convenience.
The manual lawnmower consists of several blades (knives), which are specially sharpened so that they do not touch each other when working. Thanks to this design the lawn is mowed very accurately, quickly and safely.
The cutting drum is driven by massive wheels, usually made of durable plastic. The blades themselves are made of hardened steel with a non-stick coating, to make the blades resistant to everything (water, dirt, etc.). д.). If you want to buy a mechanical lawn mower with a long life, it is recommended to choose models with stainless steel blades. they do not rust and will last much longer than conventional ones.
What types of mowers are there?
Lawn mowers are not just a cart with blades, wheels and engine, which has become popular thanks to foreign movies. They also include hand lawnmowers, the direct descendants of real lawn mowers, only now equipped with a motor: these are grass trimmers and brushcutters. They look similar, so they are often confused: a boom with a belt that is put on the shoulder, an engine, a cutting mechanism and a handle to operate.
Grass trimmers differ from brushcutters in less power, lighter construction, a handle for driving direction and a line as a cutting element. Grass trimmers are perfect for cutting grass, weeds and are especially good for places where a normal lawnmower is impractical. Trimmers and brushcutters have a cutting height that can be adjusted by the user by lifting and lowering the cutting part.
Externally similar to grass trimmers, brushcuts have differences: instead of a handle, they have a bicycle-like handlebar, more often a gasoline engine, the power is also greater, and the trimmer line is replaced by metal knives. However, on some models they can be replaced with a trimmer line if necessary.
What brushcutters are used for? They can effortlessly cut not only grass, but also powerful stems of garden plants: burdock, burdock, nettle, etc. Sometimes they are also used for shaping bushes and small trees, for cutting thin, protruding branches. The comfortable “handlebar” and the length of the push bar make it easy to lift and handle the desired area. Mowers with gasoline engine are noisier but more powerful.
Actually, the classic and most dimensional kind of lawnmowers in the form of a cart with or without a motor. Among their advantages are a large area of cultivated surface, an even cut of grass in height, also they do not need to be carried on themselves to cut the grass on the whole area. Good for a smooth lawn without stones and excessive trees and bushes. Therefore, it is recommended to have both a regular lawnmower and a grass trimmer or brush cutter to cut the grass around trees, shrubs and decorative elements of the site.
Gasoline and electric: comparison criteria
In this article, we will dwell in more detail on the classic lawn mowers, in particular, we will consider what type is better in one case or another and how to choose your ideal option for a cottage or private home. Lawn mowers can be petrol or electric-powered. The latter are also divided into two kinds: cordless and battery-powered.
Power and noise level
Electric models are less powerful because they cannot be fitted with a high-power motor. Network models are limited to the current consumption of 220 watts, and cordless models will quickly saturate when using higher power. Battery usually lasts about half an hour.
Small power of electric models is one of their pluses: a stone caught under the blades will kill the engine of the device, and then you only need to turn it off (just in case), take out the stone and continue to work.
You can’t do that with gasoline-powered Focus: models with 6-7 horsepower and higher can keep working, trying to grind up a nuisance, causing the blades to warp or break. This is not a bogeyman and not a reason to forget about gasoline models, rather the advice to remove stones from the site. they can beautifully cover the bed and not to worry about the safety of lawn mowers.
Another plus in favor of a less powerful electric motor. quiet operation. Yes, they make noise, but not as much as the internal combustion engine in gasoline models. The most powerful mowers often come with headphones to protect your ears from the loud roar of the engine.
Here the leading models with a gasoline engine: with long operating time and high power, they can handle even a large area quickly and accurately. Their strong point. spacious lawns, especially this advantage will be noticeable if the cottage grass has not been cut for some time. The volume of the fuel tank is calculated so that it is enough before the engine overheats. Next, you need to send the mower to cool down and only then continue to work.
Electric models do not have such performance, and therefore a large area will be more difficult to handle. There are several reasons for this:
- The small capacity of the engine;
- Limited cord length or limited battery life;
- Every 15-30 minutes the motor heats up and requires cooling to continue working.
For example, a cord length of 20 m requires a quality extension cord for a larger area, and dragging a long cord with you is not the most pleasant thing to do. This applies to home and garden plots with a large lawn area. For an ordinary lawn in front of the house, an electric model with a cord or battery will be quite enough, so do not write it off.
Hence the conclusion: for a large area it is better to buy a model with a gasoline engine, and for a small or medium-sized area a less powerful electric lawnmower is quite enough.
Both types of lawnmowers have their disadvantages: gasoline models with a combustion engine emit exhaust fumes during operation, and the electric motor cannot be turned on in rain or high humidity conditions, such as when there is dew on the grass or in fog.
Separate mention should be made of cases with a long cable: firstly, the use of a household extension cord in wet weather is a bad idea in itself, and secondly, there is a risk that the long wire can get under the blades and at best cause a short circuit, at worst. a serious electric shock. When working with a corded electric lawnmower, it is advisable to wear rubber boots for safety.
But they are both safe and comfortable to operate if you comply with safety regulations. By the way, manufacturers equip their models with cable strain relief and motor overload and overheat protection: the lawnmower simply shuts off, allowing you to continue working only after the motor cools down.
In terms of maneuverability and ease, the absolute leaders are electric models. Small engine and dimensions allow teenagers, women, the elderly to work with them with ease, so they are popular among retired gardeners.
Models with a gasoline engine are heavier and clumsier, especially high-powered units. You can compromise with a model with a medium power engine: such a unit will be lighter, but will allow you to treat a sufficiently large area.
Gasoline and electric: comparison criteria
In this article, we will dwell in more detail on the classic lawnmowers, in particular, we will sort out what type is better in one case or another, and how to choose your ideal option for a cottage or private home. Lawn mowers can be petrol or electric. The latter are also divided into two types: mains and battery-powered.
Power and noise level
Electric models are less powerful, since it is impossible to install a high-power motor on them. Network models are limited to current consumption of 220 watts, and cordless models will quickly saturate when using higher power. Usually enough battery power for about a half-hour’s work.
Low power of electric models is one of their pluses: the stone caught under the blades will shut down the device’s motor, and then the only thing left is to turn it off (just in case), take out the stone and continue working.
It will not work with gasoline-powered Focus: models with 6-7 horsepower and above can keep on working, trying to grind the stone, and the blades will get crooked or broken as a result. This is not a bogeyman and not a reason to forget about gasoline models, rather the advice to remove stones from the site. they can beautifully cover the bed and not to worry about the safety of lawn mowers.
Another plus in favor of a less powerful electric motor is the quiet operation. Yes, they make noise, but not as much as a combustion engine in gasoline models. The most powerful mowers often come with headphones to protect your ears from the loud roar of the engine.
Here the models with petrol engines are in the lead: with long operating times and high power they can mow even a large area quickly and effectively. Their strong point. spacious lawns, especially this advantage will be noticeable if the grass has not been mowed for some time in the country house. The fuel tank capacity is rated to last until the engine overheats. Next, you need to send the mower to cool down, and only then continue to work.
Electric models do not have such capacity, and therefore a large area will be more difficult to handle. There are several reasons for this:
- small motor power;
- The limited length of the mains cord or limited battery life;
- every 15-30 minutes the motor heats up and requires cooling to continue working.
For example, a cord length of 20 m requires a quality extension cord for a larger area, and dragging a long cord with you is not the most pleasant thing to do. This is true for cottage and home plots with a large lawn area. If you have a regular lawn in front of your house, an electric corded or battery operated lawn chair is probably all you need and should not be written off.
The conclusion is that a petrol lawnmower is better for a large lawn. A smaller or medium-sized lawnmower will be sufficient for a smaller or average lawn.
Both types of mowers have their disadvantages: petrol models with internal combustion engine emit exhaust fumes while working, and the electric motor cannot be used in rain or high humidity conditions, such as when dew on the grass or in fog.
cases with an extended cable deserve a separate mention: firstly, using a household extension cord in wet weather is a bad idea in itself, and secondly, there is a risk that a long wire can get under the blades and at best cause a short circuit, at worst. a serious electric shock. When working with an electric lawnmower for safety, it is advised to wear rubber boots.
However, both mowers are safe and comfortable to wear, as long as safety regulations are observed. By the way, manufacturers provide their models with protection against cable strain and protection against overload and engine overheating: the mower simply turns off, allowing to continue the work only after the motor cools down.
For maneuverability and lightness the absolute leaders are electric models. The small motor and dimensions allow teenagers, women, the elderly to work with them with ease, so they are popular among retired homeowners.
Gasoline-powered models are heavier and more clumsy, especially high-powered models. The compromise is a model with a medium horsepower engine: it will be lighter, but will allow you to work a fairly large area.
What to look for when buying?
In addition to the type of engine, there are additional parameters that can influence the choice.
Small power models include electric models up to 1.5 kW and gasoline models up to 2.5 l. с. They are great with young grass on a small lawn, but for the jungle, it’s better to get something more powerful. Generally inexpensive and lightweight.
Electric models with 1.5-2 kW or petrol engines with 2.5-6 hp. с are mid-level lawnmowers that work well and quickly, even on uneven areas with a slope, overgrown grass. expensive and heavier.
6 л. с. and higher. only for models with internal combustion engine for professional and semi-professional use. High-performance, high-efficiency, reliable. but at a much higher cost and requiring professional maintenance.
Mowing width and height
The larger the cutting width, the faster the area can be mowed. On the other hand, it is not always convenient if there are flowerbeds, paths, trees and other obstacles on the site. Usually the width of the cutting part depends on the motor power.
Small. 30-40 cm, and the total area of the lawn is usually up to 500 square meters. Average. 40-50 cm, and the area. up to 1000 sq. m. м. Large. 60 cm and the area up to 2000 squares, and above this. the fate of professional models with a width of the cutting part up to 120 cm.
The height of the cutting part in inexpensive models is non-adjustable: these are suitable only for a very flat lawn. Where there are rough terrain, stones, and roots, it is best to choose a model with an adjustable cutting height.
Type of grass ejection
Grass ejection can be of several types: rear or side, mulching and into the grass box. Inexpensive models leave behind a trail of cut grass, which then have to be manually “combed out” with a rake. Side discharge comes in handy for mowing lawns by the curb. the cut grass is easy and convenient to collect.
The mulch function is only good for cutting dry, soft grass. it covers the lawn with a protective layer. If you try to use it on fresh grass, the cuttings will pile up into clumps, preventing the growth of new grass.
Grass catcher bag models are the most convenient: grass goes straight into the container, from where it can be removed later and used for compost or other purposes.
Some models work on the “3-in-1” principle.
Grass catcher type
The soft mesh grass catcher bag is lightweight and does not inflate when full, so it is easy to see how full it is. A rigid bin is good for fresh or wet grass: you only have to rinse it out with water after mowing, but it is more difficult to check the filling level.
With a full container, the mower may start to slip, so you should control the amount of grass in it.
Type of drive
There are self-propelled and non-self-propelled lawnmowers. In the first case, the engine does not only turn the blades, but also the wheels, so the user only has to control the mower. Second mowers have an engine that only drives the blades of grass, but the user is responsible for moving the mower across the lawn by pushing it in front of him.
Of course, it’s best to choose a self-propelled model. Petrol lawnmowers are available with front wheel drive, rear wheel drive and all-wheel drive.
The front-driven models are convenient when turning. all you need to do is to point them in the right direction. Can slip when the grass catcher box is full. Only suitable for even lawns.
Rear-wheel drive models with large wheels are not afraid of uneven terrain, work well on slopes. Difficult to turn: you have to lift them to maneuver.
All-wheel drive models. like a good off-roader. Not afraid of hills, marked topography, gasoline engine and powerful wheels allow them to work in any weather. The disadvantages are the weight of about 50 kg and the high cost. Suitable for large areas of work.
Drum Mechanism (cutting blades spirally wound on a rotating drum) is available on mechanical and some electric models. mechanism ensures a good smooth cut (as if using scissors), but these mowers are low-powered and not suitable for neglected areas with high grass.
Rotor mechanism (The cutting disk or blades are located on a vertical shaft) is found on all gasoline-powered and most electric models. It is a universal mechanism, suitable for tall grass, the cutting height is adjustable, which makes it possible to mow areas of relief.
|Drum mechanism||Rotor mechanism|
Casing and deck material
Plastic, impact-resistant composite, steel are used to make lawn mowers. Plastic the cheapest and lightest material, non-corrosive, but can be damaged by heavy mechanical abuse. Shockproof composite Shock proof but can burn out in the sun (store the mower under a roof). Steel. the toughest material. But heavy and prone to corrosion.
Type of handle
A comfortable handle can make mowing much more enjoyable. So pay special attention to handle functionality.
The handle can Adjustable in height, and sideways, making it suitable for different operators. Anti-vibration handle absorbs vibrations from the mower, making your work more comfortable. In terms of design, the handle can be ergonomic (It is angled to put the operator in the most natural position.). Folding handle Makes storing and transporting the mower easier.
|Ergonomic handle||Folding handle|
Preferred option for any terrain. Wide wheels with a coarse tread pattern. They provide easy operation and less damage to the grass during operation.
The extras (names, like Husqvarna mowers)
InStart. Easy start function. There is a lever on the handle of the mower. And when you pull and lock it, you’re ready to go. The lever returns to the home position when mowing is complete. AutoWalk. the speed can be controlled with one hand using the lever on the handle. AFTech. Deck, blade and chute design. It has a powerful air flow that fills the grass catcher box as much as possible, without emptying it often.
In the end, when choosing a mower, it is important to consider your lawn. There is no universal model, so you need to pay attention to many criteria that will satisfy exactly your needs. It’s important to consider not only your lawn, but also who will be mowing it.

What lawn mower is better to buy: choose the type and model
With the advent of summer the owners of private plots and cottages think about how to put in order their lawn. an important component of landscape design. And the best solution to the problem will be to buy a lawn mower. However, making the right choice with all the variety of models and brands is not so easy. In our review, we’ll talk about how to choose a lawn mower based on your individual needs and rank lawn mowers in three different categories of this gardening equipment.
How to choose the right lawn mower? To begin with it is necessary to understand the functional differences between lawn mowers and similar garden and park equipment: trimmers and brush cutters. Often the owners of suburban property do not see a significant difference between the equipment, which is fraught with errors when choosing equipment.
- Lawn mower. it is a medium-sized and powerful lawn mower on wheels for cutting grass on a flat landscape.
- Grass trimmer is a small power tool, designed to be carried in hands, consisting of a cutting element, boom and motor. Grass trimmer is used when it is necessary to cut the grass on an uneven surface, in hard-to-reach places and near plants. This device is usually used for treating relatively small areas. Or for mowing up the remaining areas where the lawnmower has not passed.
- Lawn mower (lawn mower) is a more powerful and structurally more reliable version of the grass trimmer. Designed for mowing tall grass and uneven areas. It can be used as a basic tool for maintenance of the area when there is no possibility to use a lawn mower, but because mowing is done manually and unevenly, it is not suitable for use on lawns.
So, we’ve determined that a lawn mower is the best option for areas with a flat landscape and simple geometry. However, this is only the beginning. Next you need to choose the type of mower. For ease of perception, the classification of mechanisms, the principles of individual models, as well as their advantages and disadvantages are shown in Table 1.
Table 1. Principles of lawnmowers
|Type of motor and power source:|

How to choose a lawn mower
A good choice of lawn mower requires correlation of its technical and functional characteristics with the specifics of the area to be mowed and the user’s preferences. To do this we recommend that you make a table with the criteria you have specified (personal preferences and site conditions) in one column, the second column shows whether the mower’s features correspond to the criteria, e.g. “1. yes” and “0. no”, the third column shows the weight you give to each of them. The most significant factors will have the maximum weight. a multiplier of points.
You can use our test that will considerably simplify your choice of lawnmower type (table 2). To calculate the result add up the points corresponding to your answers and compare the obtained value with the nominal values (given at the end of the table).
the grass trimmer looks like a handle with a cutting element attached to the end. Lawn mower. it is a large device on wheels, the cutting element is located at the bottom of the body. You don’t have to carry it behind you, you only have to push it (or pull it), which makes it much easier to use. There are self-propelled models, where the motor simultaneously with the cutting element drives the device itself, the user only needs to control the direction of movement.
It is impossible to trim the grass to one length with a trimmer: there will be variations in any case. Lawnmower, on the other hand, allows you to level the lawn to a single length (usually 3 to 7 cm, the user chooses the desired length of the lawn). Lawn mowers are most often used on large and flat areas of grass, as they cope with mowing the grass in inaccessible places worse than the grass trimmer.
Depending on the power supply there are the following types of lawnmowers: electric, battery-powered, petrol and mechanical. In this rating we will consider only the first three types of the device.
Top 10 list according to KP
Bosch ARM 37
The budget model of a well-known brand opens our rating. This model runs on electricity, which limits its use over long distances from the outlet. However, it allows you not to worry about the availability of gasoline or the completeness of the charge.Durable plastic body, grass cutting height regulator, 40-liter grass collection container make this lawn mower one of the best options for the care of a small area near the house.
Lightweight and compact lawn mower ideal for a small area. One of the main advantages can be called maneuverability, will be able to effectively mow the lawn of any shape. Battery operated, it needs no permanent power supply.An additional advantage can be called the mulching function: the cut grass can be immediately shredded inside the device and distributed over the lawn as a natural fertilizer. Edge combs allow you to catch grass from the edges of the lawn and mow it efficiently.
Champion petrol lawnmower with wide grip. Powerful and powerful option for medium-large area mowing. Does not require access to power.With its power, this lawn mower efficiently handles rough grass and uneven surfaces. Can clear anthills out of the way and won’t break when it hits the ground or rocks. Mulching function turns grass into a natural fertilizer and distributes it over the lawn. No additional container for grass clippings, however.
Handy cordless lawn mower for small spaces. When using on a large area the battery power may not be enough. the claimed area of mowing is 250 square meters, but in practice it depends on the length of grass, its succulence, as well as the state of the battery at a particular time.Very lightweight model with a solid grass catcher box, a good option for a small area. Easy replacement and low cost of batteries allows you to alternate them as needed during mowing.
Perfect for uneven terrain. Self-propelled, with a powerful enough motor and wheels, it goes over any rough terrain. But it can be a problem when working on soft ground: its weight can leave wheel marks on the grass.
Easy to assemble and start, initial installation shouldn’t take more than 20 minutes. However, it is heavy to maneuver because of its weight, making it unsuitable for owners of complex shaped terrain.
Domestic producer model is cheaper than its many analogues, but it mows the grass well. May have problems with particularly thick grass or uneven terrain, but generally an excellent option for small and flat areas.
AC power means you don’t have to worry about recharging the battery, but you don’t have to stray too far from the power source. In addition, the cable must be constantly monitored to make sure that it does not get under the blade of the lawnmower.
Stylish-looking mains-powered model. It has a roomy and rigid tank for the cuttings, and it also comes with mulching attachments.
It’s manoeuvrable and easy to pull off, but a little heavy on bumpy terrain. Stones and tough twigs will dull the blade very quickly, the plastic housing can be cracked.
Another Champion brand ambassador in our selection. It is a self-propelled model with a soft grass catcher box. It’s easy to push and does not require a lot of pushing. However, the maneuverability is lower than in other models, so it is not convenient for lawns of complex shape.
Handles thick grass and weeds. Two ways to throw grass: to the side or into the grass catcher box. The self-wash function is a real advantage, just attach a hose and switch it on for a few minutes, after that it’s clean and ready for storage.
Petrol lawnmower has a metal housing. It mows even uneven terrain and its big wheels help you negotiate almost any bump. Although the heavy weight makes it hard to push on a bumpy surface. The Makita PLM4626N is the choice for a medium-sized area. The brand is known for its reliability and rare failures.
The self-propelled lawnmower mows a medium sized area without effort. The heavy weight is paid off by the fact that you do not have to push it yourself, just control the direction of movement. Large wheels make it easy to overcome obstacles and uneven terrain.Mulching nozzle included, but it can be purchased and installed separately. Several ejection options are available to choose the one best suited to your needs.
What to look at when choosing a portable trimmer for the grass?
The most important characteristic is power. The higher it is, the better and faster the grass trimmer mows, but at the same time the noise and vibrations will also be higher. Electric trimmers have a power output ranging from 250 watts to 1700 watts.
Power up to 600-700 watts is good for taking care of small untrodden areas, trimming edges. These machines are often used in addition to a more powerful trimmer or wheel mower. 1000-1200 W is a serious power for an electric grass trimmer. Well, and 1500-1700 watts. it’s so not economical that it is more profitable and reliable to buy a gasoline trimmer for the grass. Power models running on gasoline (from 1 to 7 liters).с.This may be only a line for a trimmer or a line for a trimmer line and knife (disk, rarely. only a knife), it is usually enough to care for difficult and neglected areas, and here the increased power of four-stroke engines is needed, not only for mowing, but also for movement of the unit.
Another important parameter is what the cutting block is made of. It can be only a line for trimmer or a line for trimmer and a blade (disk), and seldom. only a blade. A line for a trimmer is an expendable material, it may suddenly run out, and then a knife will help a lot. The knife can get blunt or shrunk. then the trimmer line. Although each user with experience understands what is good for what: someone uses a knife to cut bushes, someone likes a thick trimmer line better, and the knife is used for trimming. In most cases (especially low-priced trimmers) a thin trimmer line of poor quality is included, even with name-brand trimmers. Experienced users immediately change the line for the trimmer to a thicker. 1.6-2 mm in diameter.
They are powered by human muscles. They consist of a housing on wheels with cutting blades inside. A distinction is made between spindle mowers and hand lawnmowers. With the former, the spindle blades are driven by energy transmitted from the spinning wheels as the mower moves. Spindle mowers can be either contact (blades cross over each other) and non-contact (a gap is left between the cutting elements). They all cut the grass as it is fed to the blade.Users with experience note that spindle mowers process the lawn worse: the same places need to be passed several times.Manual mechanical lawnmowers have a rotating cylinder with blades attached to it. These mowers have adjustable elements, the grass is cut cleaner, and the manual mower is considered more durable than the spindle mower.
Advantages of all types of mechanical lawn mowers:
- autonomy. no need for wires, fuel, etc.д. The mower is always ready for use;
- Simple device. will operate properly for many years, and repairs are not difficult. Requires minimal maintenance;
- Quietness. the absence of any engine makes mowing quiet;
- Environmentally friendly. no exhaust emissions.
- they are only effective for small lawns
- not suitable for uneven, hilly terrain;
- The quality of cut is lower than on mowers with engines.
Electric lawn mowers
Cutting elements are powered by an electric motor. For convenience, 4 wheels and a handle with device controls are attached to the body. The electric mower is pushed forward, and the blade (or more) cuts the grass evenly. Depending on the model, the mowing head can be either battery operated or mains powered. Ideal for smaller lawns.
Advantages of electric mowers:
- relatively low price. gasoline models usually cost more;
- easy to work. turn it on and push forward evenly. Due to the low weight of the device, you do not have to exert much effort;
- Good quality mowing, good performance.
Disadvantages of electric mowers:
- the range of area treatment is limited by the length of the electric cord. You may have to use extension cords, which is not always safe. Having a battery doesn’t really solve the problem. From batteries, this unit runs for 15-30 minutes and then takes a long time to charge;
- not suitable for high grass and neglected areas;
- It is not recommended to mow wet grass because of the risk of electrocution.
