Lawnmower Advisor & Tests: How to Choose the Right Product

The need for lawn care

The gardening season begins in spring, when the first rays of sunshine drive away the gloomy winter mood and lure us outside. At least By then, your own garden should look appealing and well-kept in order to be able to do justify its role in retreat and oasis of relaxation. The key here is a well-tended lawn.

Celebrating garden parties, walking barefoot and playing football

A well-tended lawn provides a basis for many outdoor activities. A wild, overgrown meadow certainly has its charm, but is not particularly suitable for the children to play football and romp around. Walking barefoot on a well-tended lawn is much more pleasant.

 

A well-tended, smooth lawn is also needed for setting up garden furniture. Garden tables, chairs and loungers are more stable on it than on a wild meadow. And who do not want to make sure that the table doesn’t wobble and the coffee cup doesn’t tip over while enjoying a relaxed coffee in the garden? Also the same applies to the barbecue at a garden party. A lush green lawn creates a particularly nice atmosphere. Also it is much more pleasant to stand on a soft grass carpet than on a concrete or paved terrace.

Support with lawn care

Hardly anyone has the time and inclination to meticulously trim their lawn to the right length with nail scissors. Sickle and scythe require a certain skill and are rather poorly suited for larger lawns. Hedge trimmers and grass trimmers are also rarely the right tool. So a suitable lawnmower has to be made to take care of the lawn.

 

If you are looking for a suitable lawnmower or if you are unsatisfied with your existing one, our purchasing advice will help you find a suitable model. In our comparison of the best lawnmowers, we first introduce the most common types of lawnmowers with their respective advantages and disadvantages, explain the most important purchase criteria that you should consider and go into specific lawnmowers. You will also find useful tips about a well-tended lawn and a summary of tests and results.

Petrol or electric?

Basically, the lawnmowers on the market can be divided into two main types according to their operating mode: petrol and electric lawnmowers. Below we explain the advantages and disadvantages of the two and for which purposes they are suitable .

Petrol lawn mower: ideal for large lawns

Petrol lawn mowers are characterized by their powerful petrol engine. Despite all efforts to make electric motors socially acceptable, they have not been able to keep up with internal combustion engines in terms of performance so far. Which makes petrol lawn mowers ideal for mowing large lawns, as larger cutting widths are possible with a more powerful engine. Because of that, petrol lawn movers are usually equipped with larger collecting baskets. While electric lawnmowers with less engine power often reach their limits even on slightly taller and damp grass, petrol models usually do not cause any problems.

 

Due to the petrol operation, no power connection is necessary, which makes the petrol models very flexible. Users can move around freely in the garden with the device without having to worry about a power cable or the battery life. Modern petrol lawn mowers requires significantly less effort than with earlier models, and usually starts with a quick pull by hand. Alternatively, there are petrol lawn mowers models which comes with a convenient electric starter or start button.

Wheel drive for more comfort

Compared to electric models, petrol lawn mowers are usually more robust. Among other things, your engine is protected by an aluminum housing. The robust construction promises a long service life, but also means a comparatively high weight of around 25 to 35 kilograms. Some manufacturers are remedying this problem by equipping their petrol lawn mowers with wheel drive, which makes working with the heavy equipment much easier. The self-propulsion reaches an average speed of 3.5 kilometers per hour and can be switched off at any time. Depending on the model, the drive speed can also be regulated. A drive lawnmower is particularly recommended for users who want to mow uneven surfaces like hills with their lawnmower.

Disadvantages of Petrol lawnmowers

Petrol lawn mowers have other disadvantages in addition to their higher weight compared to the electric versions. The petrol engine produces more power, but it is also significantly louder than an electric motor, generates exhaust gases that harm people and the environment. Petrol models are more complex than the electric version, which makes maintenance more time-consuming and more frequent. Since more sensitive parts such as the petrol line, oil filter and spark plugs are built into petrol-powered motor their maintenance usually requires a specialist.

 

Another disadvantage: The price. On one hand, petrol lawnmowers are significantly more expensive than the electric version, with prices between 200 and 600 pounds and on the other hand, there are regular petrol costs.

Advantages
  • Suitable for large lawns
  • High flexibility
  • No power source necessary
  • Powerful engine
  • Robust construction
  • Often with wheel drive

Disadvantage

  • High volume
  • Exhaust harmful gases
  • More care and maintenance required
  • Expensive (purchase + petrol)
  • High weight

Electric lawn mower: quiet and emission-free

As the name suggests, the electric lawn mowers are powered by electricity. This works either via cable or battery. In everyday parlance, the term electric mower is often used for the wired variant. For both with cable or battery, we use “electric” in our lawnmower comparison.

 

Electric lawn mowers have the major advantages over the petrol models as they are significantly quieter and do not emit harmful exhaust gases. They usually weigh less, which means that they can be pushed over the lawn with less effort, so that mowing even angled lawns are not a problem. Electric mowers has low maintenance as compared to petrol ones, and usually no specialist is required.

With a power cable or a battery?

Battery powered lawn mowers has the advantages that they can be pushed more comfortably and flexibly over the lawn as there is no power cable, which also eliminates the risk of accidentally mowing over the power cord and damaging it. Disadvantages compared to the wired version are the higher weight due to the battery and are usually comes with higher purchase price.

Disadvantages of electric lawn mowers

It goes without saying that corded lawnmowers have a limited range of motion. But even battery-powered mowers are not as free in their range as the petrol-powered ones. Because the battery doesn’t last forever. Depending on the model and engine power, a fully charged battery can run out after 15 minutes. Has a comparatively weak engine, which is also a limitation. The electric models are inferior to the petrol engines, especially on wet and tall grass. Both wired and battery-operated electric models are therefore more suitable for smaller lawns up to a maximum of 400 square meters.

Advantages
  • Quiet
  • Eco friendly
  • Low maintenance
  • Inexpensive wired models
  • Light in weight

Disadvantage

  • Weaker engine
  • Limited range of motion
  • Battery variants expensive
  • Not suitable for large areas

In summary: which lawn mower is suitable for whom?

Petrol lawn mowers are powerful and flexible, but loud, polluting and expensive. They are particularly suitable for consumers who want to use them to mow larger lawns, monre than 400 square meters, and taller grass. For smaller areas we recommend an electric lawn mower. The variant is significantly quieter and more environment friendly. With a wired variant, consumers even save a lot of money compared to petrol powered mover. It is suitable for users who have a good power connection in their garden, who want to spend less money and who do not bother about power cable when mowing. If you want to be a little more flexible and do not mind spending some more money on it, a cordless lawnmower is the right choice.

Important purchase criteria for Lawn Movers

Grasses and lawns have their own preferences and you can tell if they are properly cared for by their owner or not. Lawn lovers should consider a few decisive criteria before buying one in order to find the model that suits their needs and their lawn. Below, we provide you with five important decision making points.

The cutting height of the lawn

For a well-tended lawn, it is important to determine the optimal cutting height. If you cut off too much, the grass cannot grow vigorously. If, on the other hand, you cut too little, you will soon have to reach for the lawn mower again. Therefore, when choosing your new lawnmower, you should pay attention to the cutting heights it supports.

How high should the lawn be?

Which cutting height is the right one depends largely on the type of lawn. For normal lawn, it is roughly between 3.5 and 5 centimeters. With the so-called shadow lawn, it is better to leave one or two centimeters more so that the blades of grass can absorb enough sunlight. For ornamental lawns, on the other hand, the optimal cutting height is between 1.5 and 2.5 centimeters.

 

Depending on the model, you can set the appropriate cutting height for your lawnmower either in centimeters or in steps. If the latter is the case, you can usually read in the operating instructions which level corresponds to the desired cutting height. Many models have a convenient central cutting height adjustment . With some devices you have to adjust the cutting height separately on two or four wheels, which is a bit more laborious.

What does mulching mean?

The term mulching refers to the large-scale covering of the soil with non-rotting organic materials. Crushed tree bark, the so-called bark mulch, is used particularly often. However, fallen leaves or freshly mown, shredded grass can also serve as mulch. Mulching adds nutrients to the soil and keeps it fertile in the long term. Some models from our comparison also have a mulching function.

The cutting width

Also known as the working width, Cutting width is almost same or more important than cutting height options of a lawnmower. It influences how quickly users can mow a lawn using it. Machines with a wide cutting width can process the same lawn area faster than those with a narrower cutting width.

 

From this one could now conclude that it is worthwhile in any case to choose a model with the widest possible cutting width. However such lawnmowers are a bit more expensive, less agile and heavier than lawnmowers with a narrower cutting width, It also require more space. Mowing small, winding gardens is rather difficult with such chunky lawnmowers. When choosing the cutting width, you should roughly follow the lawn to be mowed. The following list provides a cutting width guide.

  • Up to 250 m² lawn area: 30 to 40 cm cutting width
  • 250 to 500 m² lawn: 40 to 50 cm cutting width
  • 500 to 1,000 m² lawn: 50 to 55 cm cutting width

Bottlenecks in the lawn are another decisive criterion for choosing the right cutting width, for example between stone beds, tree trunks or bushes.

The engine power

The power of the lawnmower’s engine determines how well the machine can cope with thick and long lawns. More powerful devices are better suited for larger areas. For small front gardens, for example, a cordless lawnmower with a low motor output of 800 watts or a little more is usually more than sufficient.

 

Most commercial electric lawn mowers have an engine power between 1,300 and 1,700 watts. This gives you enough power for medium-sized gardens (with around 200 to 400 square meters). Powerful electric lawnmowers work with 2,000 watts or more. However, users should note that such models also consume more electricity.

 

Petrol engines are more powerful than electric motors. Depending on the model, they have an output of 1,500 to 3,500 watts (around two to five hp). Powerful petrol lawn mowers easily mow thick, tall and wet grass and are suitable for large gardens of up to around 1,400 square meters. Especially for hilly gardens you should choose a device with wheel drive so that pushing is not too difficult.

The weight

On large extent, how comfortable a lawnmower is to operate depends on its weight. Heavier devices are usually more difficult to push across the lawn. Pushing a heavy lawnmower can be very uncomfortable, especially for elderly people or people with back problems. Typically, electric lawnmowers are noticeably lighter than petrol-powered ones. The devices can be roughly divided into three different weight classes.

Weight class Weight range Lawn mower type Effort
Light Up to 15 kg Hand lawn mower Low
Medium difficulty 15 to 25 kg Electric mower Average
Heavy About 25 kg Petrol mower High

Different weight classes of lawnmowers at a glance.

 

In order to be able to push heavy petrol lawn mowers easily, it is advisable to choose models with edge drive.

The Noice

The noise emitted by a lawn mower may define when you can use it. Petrol lawn mowers, in particular, can be pretty loud. Under certain circumstances, mowing the lawn can be counted as a disturbance of the peace and can be punished with a fine.

 

So if you want to stay a little more flexible and use your lawnmower around lunchtime, for example, you should use a quieter electric model in order not to risk a fine and not mess with the neighbors.

Helpful equipment

Many lawnmower manufacturers equip their models with various additional features and functions, which mainly increase ease of use or are used for lawn care. We present some of the most common ones below:

Wheel drive

In the case of wheel drive lawnmowers, the motor not only drives the blade, but also the rear wheels. This means that the lawnmower moves across the ground under its own power, the user only has to guide it. A lawnmower with drive is particularly advantageous for heavy equipment and sloping terrain and increases the ease of use enormously.

Electric start

With petrol lawn mowers, an electric start function makes starting the engine easier. Instead of using a powerful cable to get the lawnmower up and running, users simply have to press a button and the lawnmower starts up.

Grass catcher

Most commercial electric and petrol lawn mowers are equipped with a grass catcher. This is where they collect the mown grass so that users don’t have to rake it up after mowing. The larger the catcher, the less often you have to empty it in between. For larger areas, a larger collecting basket is accordingly recommended.

High wheel

So-called high wheels are extra-large wheels. Lawn mowers with such XXL wheels can be pushed more comfortably over bumps and mossy lawns without getting stuck or stuck.

Knife coupling

Some petrol lawn mowers are equipped with a blade clutch, also known as a blade stop. This function ensures that the lawnmower’s knife stops as soon as the user releases the safety bar. The engine continues to run. The knife coupling enables, for example, to empty the grass catcher without having to restart the motor.

Mulching function

Lawn mowers with mulching function make it possible to close access to the grass catcher, which means that the grass is cut several times and thus more finely and is then distributed on the lawn as fine pieces of grass. Special mulching mowers do not even have a grass catcher. Those who mulch regularly do not usually need to fertilize their lawn.

Side discharge

An alternative to lawn mowers with grass catchers and mulching mowers are models with side discharge. With side discharge, the cut grass is not directed backwards and collected in a collection bag, but rather placed on the side next to the lawnmower and then collected by hand.

Scarifying function

When scarifying, the sward is scored with a special cutting tool. This removes old cuttings and moss and promotes aeration of the soil. Some lawnmower models are available with a scarifier attachment. This saves consumers the purchase of an additional garden tool. Alternatively, some manufacturers offer scarifying attachments for various lawn mowers.

Special types of lawn mowers

In addition to the classic lawnmowers, which are available with either petrol or electric motors, the market also offers special variants. Below we explain what distinguishes them and for which consumer groups and purposes it is worth buying.

Robotic lawnmowers: energy and time saving

Thanks to clever technology in miniature format, it is now becoming easier and easier for private consumers to have unpleasant work done by specially developed devices. Suction and wiping robots are leading the way, meanwhile the little helpers are also available as garden tools for mowing the lawn. Robotic lawnmowers do the lawn mowing independently and quietly. To do this, users must define the area to be mowed with a boundary wire before they can be used for the first time. Modern robotic lawnmowers can also mow larger areas without any problems. Depending on the model, they are suitable for lawns from 200 to 800 square meters. However, robotic lawn mowers are still comparatively expensive. A price of at least 500 pounds should be budgeted for the purchase. In addition, the self-contained lawnmowers are unsuitable for rough terrain and steep climbs.

Cylinder mower: gentle on lawn and the environment

The so-called cylinder mower, also known as a hand mower, is the original form of the lawn mower. The typical cylinder mowers are operated by hand and are therefore particularly environmentally friendly. In addition, these garden tools mow the lawn very quietly, gently and precisely. There is usually no grass catcher, cylinder mowers are primarily used for mulching. Because of the precise cut, cylinder mowers are used on football and golf courses, but mostly as an electrically operated variant. In the private sector, hand-operated cylinder mowers are mainly suitable for very small gardens and environmentally conscious consumers who like to cut their lawn very precisely.

Air cushion mowers: floating devices for steep slopes

Another special type of lawnmower is the futuristic-looking air cushion mower. Unlike the other types of lawn mowers, they do not move on wheels. Instead, there is an impeller on its underside next to the cutting knife, which ensures that they float on an air cushion over the lawn. So that this works, particularly lightweight components are used for air cushion mowers. Air cushion mowers are usually operated with an electric motor. In addition, most manufacturers do not use catch baskets for the lowest possible weight. Air cushion mowers are particularly suitable for smaller lawns with sloping slopes, angles of inclination of up to 60 degrees are no hurdle for the floating lawnmower. In addition, they are particularly easy to push and are easy on the muscles and joints when gardening.

Bar mower: ideal for uneven terrain

Bar mowers are characterized by the fact that the cutting tool is attached to the front and in the form of a wide bar, which makes them resemble a combine harvester. These special lawn mowers are both hand-operated and motorized. The effective knife mechanism, which is located on the beam and is reminiscent of many small hedge trimmers, easily grips and cuts tall grass, grain and smaller shrubs. The bar mower is also noticeable because it only drives on two wheels. This makes it particularly manoeuvrable and is ideal for uneven terrain and hard-to-reach places. It is mainly used for agriculture, for example for the procurement of animal feed. Motorized devices are also good for mowing mountain slopes.

Lawn tractors: comfortably mow large meadows

Lawn tractors are considered the kings of lawnmowers. The driver can feel like a king when he drives relaxed across the meadow on his tractor while trimming the lawn to the right length. The big disadvantage of lawn tractors: their price, which starts at around 1,200 pounds. In addition, they are of course much larger than classic petrol or electric lawnmowers and require sufficient storage space. They are recommended for large lawns from 2,000 square meters. Smaller, especially winding gardens are less easy to mow with, and a lawn trimmer is also suitable for corners.

Tips for a well-tended lawn

The right lawn mower is the first step towards an optimally cared for lawn. If you then follow the tips below while mowing, nothing can go wrong.

1. Prepare for lawn care

Before you mow your lawn for the first time in the spring, you should definitely remove all autumn and winter residues like fallen branches and leaves so that nothing other than grass gets under the blades which can cause damages. Before mowing, you should also make sure that there are no other objects such as stones or toys on the lawn. One must also get rid of molehills, otherwise the heaped earth will cause blunt knives.

2. It is better to mow a little more often

Particularly in the months of May and June the grass grows quickly, like up to 2.5 centimeters per week, depending on the type of grass. You should shorten your lawn at least once a week so that the lawn looks well-groomed and dense.

3. Fertilize or mulch regularly

Regular mowing is important for a well-tended lawn, but it also costs the grass nutrients. Therefore, you should fertilize your lawn about once a month to provide it with nutrients again. Alternatively, instead of collecting the grass, they can mulch regularly. The clippings then rot on the sward, with the lost nutrients being returned to the lawn. The mulch layer also prevents weeds from growing. On hot and dry days, it also ensures that the freshly mowed lawn does not dry out.

4. Follow the rule of one-thirds

If you are unsure how often to mow your lawn, you can use what is known as the one-thirds rule as a guide. It says that the lawn should only be shortened by a third each time it is mowed.

5. Do not step on the unmowed area

When mowing the lawn, be sure to stay on the mowed track so as not to kick the uncut grass. Otherwise, the grass may not be cut at a uniform height, as the flattened stalks only slowly straighten up.

6. Make sure there is sufficient moisture

So that your lawn grows and thrives in lush green, it needs sufficient moisture. If the rain has stopped raining and the humidity is low, you should water your lawn. As a rule of thumb, if the lawn has a bluish to grayish sheen and the older stalks begin to wither, watering is necessary. Extensive lawn sprinkling is particularly effective. For freshly laid lawns, it is best to turn on the sprinkler daily so that the seeds can germinate well and form roots.

 

Ideally, you should sprinkle your lawn early in the morning when the soil has cooled a little overnight. Then he can absorb the water better. If the sun is shining heavily on the lawn, it is better to leave the sprinkler switched off, otherwise there is a risk that blades of grass will be burned by poorly reflective water droplets.

7. Scarify twice a year

Score the ground with a scarifier. How to remove dead roots and weeds and ensure that the grass roots are aerated and can grow optimally. For adequate ventilation of the grass roots, it is advisable to use the scarifier twice a year: once in spring and once in autumn. With young lawns under three years of age, however, you should forego scarifying in order not to unintentionally tear the still fine, only weakly anchored roots out of the earth.

8. Sharpen the knife for a clean cut

In order for the lawnmower to cut the grass cleanly, it needs very sharp blades. At the latest when you notice frayed blades of grass after mowing, you should take your lawnmower to a specialist retailer for regrinding. This is usually necessary once a year.
