Electric shredders are fine... if you only shred small branches under 45 mm in diameter. For larger diameters without the risk of jamming or overloading, invest in a thermal chipper. We even recommend the Zipper ZI-HAEK4100, a proven model with a cutting diameter of 100 mm and a power output of 4100 W.

Machines equipped with a single-cylinder, 4-stroke (unleaded) gasoline engine with a capacity of 250 cm³ to 500 cm³ and a power output of 6 HP to 18 HP are already capable of continuously shredding large quantities of plants and branches up to 100 mm in diameter. Modern gasoline engines do not emit too many pollutants or noise, especially when they are running. Diesel-powered shredders are intended for professional use. They can handle all kinds of vegetation and branches up to 300 mm in diameter.
Orchards and parks require the use of a trailer-mounted thermal mulcher. The weir of this device allows direct storage of the waste in the carrier's box. If the area to be worked on is very large, you will need a shredder that weighs less and can be towed behind your car, truck, micro tractor or quad. For large areas, we also recommend a model that works with a turbine cutting system or is powerful with at least 3300 W. Such a unit is also ideal for hardwoods such as certain branches of fruit trees.
The noise level of a thermal unit can reach 105 dB. Choose a model that emits less noise. Indeed, a low-noise shredder will not disturb your neighbors. However, for health reasons, you should always wear protective earphones. You have the option of purchasing noise-cancelling ear pads separately on a small budget.
Some manufacturers have equipped their shredders with a manual tow bar. Therefore, their units can be towed on a lawn mower, micro tractor or ATV off highways and main roads.
You
can choose a thermal shredder based on the options: wheels (for ease of transportation), folding function (to limit the space requirement)... The most important thing in our opinion is to have a pusher available. This element will allow you to push the small branches without feeling vibrations. Also, in case of jamming, a rotor system will allow to clear the vegetation in less than no time, because you just have to change its rotation direction.
Some multipurpose shredders multiply or combine cutting systems, some for delicate plants and others for twigs and thicker branches. Rotary or turbine systems often have a drip tray or bag located under the unit. Therefore, there is no need to install a receptacle. Some collectors have the advantage of being at least partially transparent, so that it is easy to see their capacity level.
For a long time, the thermal shredder was only intended for professional gardeners. In fact, a thermal shredder has 5 times the power of an electric shredder. It is more expensive to buy and runs on fuel.
It is used for a large garden, usually over 500 m². The thermal shredder is intended for frequent use. We therefore recommend it for shredding thicker branches.
It has a power of up to 66,000 W. The most powerful of them are even equipped with a 9 HP motor. With a thermal mulching unit, you can mulch dense vegetation in record time.
This is because the presence of an electric wire does not interfere with your movements. You can work continuously on a large number of surfaces for long hours. Note, however, that the thermal version is much noisier than the electric version.
We distinguish between the following three types of mills: thermal knife mill, flail mill and fixed blade mill.
The combustion engine controls the rotation of the disc on which the cutting blades are located. As they descend under their own weight onto the disc, the plants are shredded by knife passages, then the shredded waste falls by gravity through a dam.
The knife shredding system is the simplest and most energy efficient. It is suitable for soft vegetation (small branches, grasses, leaves), but can be overloaded in volume and limited by small branch diameters. Typically, a knife is mounted on small gasoline-powered thermal chippers.
The
motorized drum may have 12 to 24 flails, usually these are equipped with "Y" shaped cutting edges. The drum pulls the plants from the chute, shreds them with the flails, and then conveys the waste through the chute (giraffe) to a collection bin.
This shredding system is very efficient, but requires more power than knife shredding. Flail shredders are then sufficiently powerful, some of which run on gasoline, and others are diesel models.
The
latter type of thermal shredder unites the feed drum with the knives, but here the blades are fixed and the branches rotate around the knives. The drum feeds this mass into the discharge chute and throws the chips through the giraffe.
The fixed knife system is very powerful and is only installed on high-powered diesel chippers.
Note that a thermal shredder is much louder than an electric shredder. Make sure you have earplugs so that your ears don't suffer!
A thermal shredder is a very powerful device. It is perfect for shredding plants in orchards and parks. A thermal shredder can be used to turn your green waste into quality compost. However, this device is particularly demanding from a maintenance point of view. The engine requires special care, such as changing the oil, cleaning the filters or the spark plugs.
The electric shredder is an inexpensive device. It is functional, but it is especially suitable for occasional use. It shreds branches over a limited area. However, depending on the power, this type of shredder can, like the electric shredder, shred hard and thick wood. It produces coarse shredded material. Unfortunately, it is not as efficient as a thermal chipper.
The thermal shredder works in a very professional way. It is suitable for large gardens. If energy is not important to you, the electric option is probably more appropriate. However, a thermal shredder is ideal for shredding a wide variety of vegetation in a short time. Also, the advantage of a thermal shredder is that it has a greater autonomy compared to an electric shredder.
Solid and reliable
It is known for its sturdiness and reliability and is able to reduce stems, leaves and branches from your garden maintenance. In general, it lasts a long time, especially if you follow the instructions for use. It is also useful for cleaning the vegetable garden and flower beds as well as for tree care.
Easy to use
Regardless of the type, using a shredder is the same and as simple as possible. You just need to master the ignition as well as the details about the different storage and retrieval concepts depending on the type of device you have. It is also easy to move it in your exteriors thanks to its reasonable weight according to the models.
Multimodel
You can get the model as well as the size of the thermal shredder that suits you, whatever the use, in a garden or in a large field. The power and autonomy vary according to the size and range you are looking for. There are many models of shredders on the market and each one has different characteristics.
Ecological tool
It is very useful for deep cleaning of trees, vegetable garden and flower beds. It also facilitates the recycling of green waste to make compost and enrich the soil. In short, in the face of a ban on burning waste, this tool is the ideal solution for maintaining your garden and preserving the environment.
Promotes energy savings
All of them have a great autonomy, no matter which type you have chosen. You can use it for hours at a time without needing to recharge it. Thermal shredders run on gasoline and are not energy hungry. Once you fill the tank, you can work without fear of running out of gas.
Spark plug maintenance
Maintain by cleaning and/or changing the spark plug regularly and remember to check the electrode gap.
Cleaning the filters
You
can also clean the air and fuel filters if your grinder is equipped with such an accessory.
Follow the proportions indicated by the manufacturer (oil + petrol)
Fill
the mixture for your 2-stroke engine (oil + gasoline) in the proportions specified by the manufacturer
.
Change your oil
Fill the
oil and gasoline mixture for a 4-cycle engine and drain the tank of used oil periodically according to the manufacturer's recommendations
.
Divide the investment
The
garden shredder has seasonal appeal. So, why not buy one communally with your neighbor? This will not only allow you to share the investment, but also to choose a more efficient and durable model.
The best thermal shredder depends on your needs and your budget. Read our buying guide to find out which products are the best at the moment.
A garden shredder is an appliance that shreds plant waste. It is suitable for all types of users, whatever the size of their garden.
