What are Stump Grinders used for?
Stump Grinders are machines designed to completely remove stumps and roots from the ground, a need that frequently occurs after tree felling. Their main function is to grind and shred the stump into chips, facilitating subsequent tillage. These tools prove essential for both professional gardeners and farmers, especially in preparation for planting new trees or crops.
The main applications of tools for removing tree roots include:
- Restoration of the soil: After removal of the stump, the land can be used again for sowing or other agricultural activities without hindrance.
- Elimination of unwanted roots : In addition to the stump, the stump-grinders allow the removal of roots that could interfere with new planting or the construction of structures.
- Maintenance of green areas: Stump grinders are often used in the maintenance of parks, gardens and public spaces, where the presence of logs could be a hazard or aesthetic obstruction.
What do stump grinders look like?
Stump grinders are tough, complex machines designed to deliver long-lasting, high performance in the toughest working conditions. The structure of a stump grinder consists of several key components that determine its effectiveness and reliability:
- Engine: In the tools for removing roots burst shafts, the engine is the heart of the machine. Common brands include Honda, Briggs & Stratton and Loncin. Honda engines are renowned for their quality and reliability, with long life and superior performance. Briggs & Stratton, a historic American brand, is the world's leading petrol engine manufacturer, offering cutting-edge power and technology. Loncin, on the other hand, offers engines with an excellent quality/price ratio, made in China, ideal for those looking for performance at a low cost.
- Belt drive Engine power is transferred to the cutter via a drive belt, a system that makes it possible to modulate the force applied to the stump and ensure homogeneous machining. The belt drive is essential to protect the motor from overloading and to prolong the life of the machine.
- Cutting Rotor : The rotor is the part of the machine that comes into contact with the log doing the shredding work. The size of the rotor can vary from 200 to 610 mm, affecting the machine's ability to handle different sized logs and the speed at which the job is completed.
- Adjusting the cut above the surface: Some models allow the cutting height to be adjusted above the surface, offering greater flexibility according to the specific needs of the terrain. This adjustment ranges from 127 to 56 cm, allowing the working depth to be customised according to the stump to be removed.
- Emergency switch-off handle: It ensures maximum safety during operations.
- Compact design: Thanks to which the machine can also be used in confined spaces.
How do tools work for removing tree roots?
The stump cutter operation is based on a simple but effective principle: use a rotor with sharp teeth to grind the stump into small chips, facilitating its removal from the soil.
- The process begins with starting the engine, which in internal combustion models can be operated via a starter rope or in more advanced models via an electric starter system. Once the engine is started, the power generated is transmitted to the cutting rotor via a drive belt.
- The rotor, which has a series of sharp and strong teeth, is positioned over the log to be removed. Depending on the size and characteristics of the log, the rotor can be adjusted in height to start processing from the most appropriate point. In the most versatile stump grinders, the cutting height can be adjusted to suit the specific demands of the job, allowing you to work on stumps both above and below the ground surface.
- When the rotor comes into contact with the stump, the teeth begin to shatter the wood, progressively reducing it to shavings. This process continues until the stump is fully shredded. The speed and effectiveness of the process largely depend on the power of the motor and the size of the rotor. Models with larger rotors and more powerful motors can handle larger stumps in less time.
- During operation, the drive belt plays a crucial role in transferring power from the engine to the rotor, ensuring smooth and continuous movement. This system also protects the motor from overloading, ensuring a long service life and minimal maintenance.
- Once the stump removal is complete, the wood shavings produced can be easily collected and disposed of, or used as mulch for the garden. The ground, now free of obstacles, is ready to be worked or planted with new crops or trees.

Stump Grinder FAQ
1. Why choose to use a stump grinder?
A cut tree trunk may take years to rot and crumble, but there is also a good chance that it will make new shoots and the tree will grow back. In addition to the fact that the wood rots, there is also the risk that diseases may develop on the rotten wood and within a short time also infest the living plants in the vicinity of the log.
The best solution is therefore to chop the wood deeply with a stump grinder until a small hole is created and then cover it with soil to prevent sunlight from reaching the rotten wood, allowing parasitic fungi to grow.
Moreover, the removal of roots with a classic excavator causes a lot of damage, whereas with the burst cutter the trunks will be removed cleanly. It is worth remembering that this is in fact an indispensable tool after cutting a plant, and you want to remove the remaining stump, thus being able to quickly restore the affected area.
2. How to remove tree stumps and roots from your garden?
Removing tree stumps and roots can be addressed in a variety of ways, each suited to different needs and situations:
- Stump grinders : This machine is designed to grind the stump into small fragments, making it quickly biodegradable. It is particularly useful when large or numerous logs have to be removed, as it allows fast and precise work.
- Chemicals: Another method is the use of specific chemicals. These products, applied directly on the stump, accelerate the decomposition of the wood, reducing it to mush after a few weeks or months. However, care must be taken as these substances can be toxic to the soil and the environment.
- Cover with a waterproof sheet :
- Manual removal : Finally, manual removal by digging with a shovel and pickaxe is only a viable option for small stumps, as it requires a lot of effort and time.
3. How to mill a wooden log?
Milling a stump of wood requires the use of a stump grinder, a specialised machine that grinds the stump into small fragments.
- Stump Grinder positioning : To begin with, it is important to position the stump cutter correctly over the stump. Make sure that the machine is stable and that the surrounding area is clear of obstacles.
- Starting the engine: Once the stump grinder is in place, the engine starts and slowly lowers the rotating blade onto the stump. The blade starts to remove wood from the top to the bottom.
- Milling method : It is essential to work methodically, moving the machine back and forth to ensure that the entire stump is reduced to chips.
- Milling depth : During operation, it is important to maintain a firm grip on the machine and pay attention to the depth of the milling to avoid digging too deep into the ground.
- Conclusion of the work: Continue milling until the stump is completely removed. The resulting wood chips can be left on site as mulch or harvested for composting.
