This is an important criterion, as it directly impacts the performance of the device. But it also depends largely on the needs of those who use this type of machine. If you are not a professional, a power estimated at around 2000 and 3000 watts is sufficient. Otherwise, the recommended power will be between 3300 and 6600 watts.
In order to function normally, a thermal plant shredder incorporates a motor that must be powerful enough to do the job properly. This engine can be powered by either gasoline or diesel. But no matter which power model you choose, keep in mind that this kind of device is primarily designed for the purpose of maintaining large areas.
Basically, this is what allows the device to cut branches perfectly. You can find 3 of them namely the blade turntable, the auger system and the knife rotor system. In addition to these, there are other systems such as the turbine system, the moving flail shredding system or the secondary hopper system.
The cutting diameter is an important criterion. For professional use, it is wise to take a diameter of 50 mm. But if you are a private individual, it is strongly advised to choose a model with a cutting diameter of 25 mm. This way, you will avoid the risk of jamming, which can impact the proper functioning of your device.
Many people underestimate this criterion, which nevertheless remains important. It must be said that a thermal shredder is not the discreet type since it emits noise during its operation. So that you don't have any problems with your neighbors, choose a device with a knife rotor shredding system! This has the advantage of being the quietest in the world.
To ensure safe use of your professional thermal shredder, various safety measures must be taken. This does not only apply to the user, but also to those around him.
When handling this machine, it is imperative that you are in the most stable position possible. Before each use, always check the fasteners. If any damage is found, have the machine repaired immediately by a professional. Using a defective machine is never recommended as it can be very dangerous.
Finally, do not forget to read carefully and follow the instructions or recommendations of the manufacturer.
The thermal shredder with fixed knives has a number of strong points that are worth highlighting. First of all, this device is appreciated for its speed of execution. With it, you're sure to save time! Secondly, it also stands out for its very fine shredding. It will compost in record time. It is particularly effective on soft branches, but also on foliage.
During operation, the thermal shredder with fixed blades may well cause vibrations. This may cause discomfort to the user. Secondly, if the shredder becomes blocked due to overloading, for example, it takes some time and effort to unblock it and use it again. Finally, this type of shredder shows its limits when shredding large shrubs.
In most cases, flail shredders use pieces of metal attached to chains at a rotating drum. This system can effectively shred leaves as well as fairly thin branches. This device is valued for its high performance, which means that it is more suitable for professionals than for the average user.
Compared to a knife model, the flail shredder may require more power. For this reason, it is not uncommon to see this type of system only on powerful devices. As a result, the user should look for models that run on diesel rather than gasoline. The latter exist, but are few and far between on the market.
Primo, the thermal shredder with knives has the merit of incorporating the simplest system. Secondly, it is the most appropriate device with regard to the cutting of soft vegetation. In terms of fuel consumption, it easily ranks among the most energy-efficient machines. Most small thermal shredders that run on petrol have this cutting system.
In spite of all the strengths mentioned above, the thermal mulcher has a few weaknesses. Firstly, this type of device is not really ideal when it comes to shredding branches with large diameters. Another notable disadvantage is that the volume very quickly reaches saturation. In short, the possibilities offered by this shredder are rather limited.
Because of their power, professional thermal shredders offer an efficient solution when dealing with branches larger than 4 cm in diameter. They also save you time, especially if you are dealing with a large quantity of wood and leaves. With them, you have more freedom since your area of action is not limited by the reach of electrical wires.
There is no doubt that professional thermal shredders are much larger than electric shredders. As a result, they may take up more space! Another problem is that they not only make a lot of noise, but also smoke. This makes them less convenient and less pleasant to use.
Professional electric shredders offer a number of advantages. They are easier to transport than their thermal counterparts. They also take up little space and therefore occupy less space. In terms of noise pollution, they are far more efficient than thermal models, emitting very low levels of noise. Last but not least, the user does not suffer from any smoke emissions.
The biggest disadvantage of professional electric shredders is that the user cannot move away from an electrical source and must have a very strong extension cord at his disposal. Another disadvantage is that their power is logically lower than that of thermal appliances. As a result, they are not capable of shredding large branches.
If you are a professional who takes care of small areas, an electric mulcher is more practical. On the other hand, if you have to deal with large areas, there's nothing better than a thermal model to take advantage of more power and possibilities. With this type of device, the time saved is also considerable.
For its ease of use
To make it easier to move, professional thermal shredders are equipped with tires. Then, so that the user can easily insert the wood into the device, most models have a double supply chute. And in case of jamming, you just have to press a button and the direction of rotation of the blades is automatically reversed.
For its robustness and long life
A professional thermal shredder is designed to be used for many years. Indeed, the design materials are intended to ensure both long-term use of the device and easy maintenance. In addition, a shredder usually has a frame made from steel or metal to ensure optimum strength. As you can see, you won't be changing shredders anytime soon!
For its power
As a general rule, professional thermal shredders can have powerful motors of over 3000 watts. It is this power that allows them to shred considerable volumes of branches and leaves in a few minutes. With a power of 6000 watts, many models manage to shred branches with large diameters without any problem.
For the safety it offers
During filling, some models have fixing brackets that allow the shredder to come to a complete stop. To prevent overloading, some models have a safety clutch. There is also an oil level indicator to protect the engine. If the engine starts to run without the required oil level, the damage it will cause will be significant.
For its practicality
Do you often trim bushes or trees? If so, you've probably already asked yourself the question, "What am I going to do with this waste?" A thermal chipper is a practical solution if you want to drastically reduce the volume of your waste. This reduces the number of trips to and from the landfill to your business area. Secondly, some models are able to turn garden waste into compost.
In our opinion, the best brands of professional thermal shredders in 2022 are :
When it comes to the world of gardening tools, the Lea brand is undoubtedly one of the best references on the market. Since its creation, it has been striving to offer quality appliances that make life easier for all users. This is reflected in its shredders! These are both robust and efficient.
Founded in 2008 in Austria, this young company has grown very quickly and has been able to become one of the major players in terms of tools dedicated to gardening.

With a diversified offer, it targets both individuals and professionals.
The diagram below will help you to get an idea of the typical prices for each price range (entry-level, mid-range and high-end).
However, more expensive does not necessarily mean better.
We therefore advise you to always consult our ranking before deciding, rather than blindly relying on price ranges.
Clean your shredder regularly
Regular cleaning of your grinder will prolong its life and maintain its quality. The motor should be changed regularly using good quality oils. After each use, you should disassemble it to clean it thoroughly. You should also oil the parts that need grease for their function, such as the wheels, axles and metal parts, to prevent rusting.
Don't forget the motor guard, which also needs to be cleaned to remove any grinding residue that might clog it.
Install the shredder away from the neighborhood
Although the thermal shredder is less noisy than other models, it would be wise to place it away from the neighborhood to avoid disturbing the most sensitive ears. Indeed, the noise could make a ruckus. Also, remember to warn your neighbors before using your device, especially if you plan to work at night.
Shred the branches 2 weeks after pruning
A thermal shredder is certainly efficient, but you can optimize its life span proceeding to shred the branches 15 days after pruning. This will make them more pliable and the machine will have no trouble shredding them. You'll also get a finer cut if you plan to use the waste to make compost.
Check the cutting system blade regularly
In addition to routine maintenance, consider checking the various devices in the cutting system. You can perfectly well do the related tasks yourself, such as replacing faulty knives or greasing the bearing if you have a notion in DIY. If not, you can entrust the task to a professional.
Remember to change the filter
Professional thermal shredders come with different types of filters depending on the built-in motor. This one can be a foam air filter, a double element air filter or an oil bath filter. It must be maintained regularly to avoid premature wear, malfunction or loss of engine power. The air filter should be changed as soon as it shows weakness or after 200 hours of use.
There are several criteria for choosing the best professional thermal mulcher. Among the most important are the motor power, expressed in W or HP, which defines the efficiency of the machine and the diameter of the wood cut. The ease of use, the sturdiness of the device and the accessories are also criteria to be taken into account.
It is essential to take care of your professional thermal plant shredder so that you can use it as long as possible. To do this, you need to clean it after each use by clearing the wood chips left between the blades and in the funnel. You should also check that the blades are sharp and change them if necessary to maintain the initial performance of the shredder.
The motor should be changed regularly to keep it clean and functional. And finally, it is necessary to carry out an annual overhaul, by dismantling the device, to check its proper functioning.
In case of blockage of your professional thermal shredder, you must, before any manipulation, stop the engine and unplug the device. Then, wait for the cutting tool to stop completely before unclogging it. To remove spent branches, use a brush and gloves. For a rotor mulcher, simply reverse the direction of rotation. Once the waste is removed, you can resume your work.
The professional thermal mulcher is a powerful device. It is used after pruning shrubs and trees in order to shred the plant waste. With its large dimensions, it is suitable for green areas and gardens with a surface area of more than 500 m2 that require frequent maintenance. Suitable for long term work by professionals, it can handle larger and denser plants, even for branches up to 75 mm in diameter.
