DT subsoilers provide deep subsoiling to restore soil porosity and biological activity. They intensively mix the soil and surface residues for rapid degradation into organic matter. Two DT models are available: the DT L for working up to 50cm deep in lighter soils and the DT XL for depths of up to 60cm, suitable for heavy soils and high-powered tractors up to 400hp.

Optimisation of agronomic benefits

Remove compacted layers of soil

Soil decompaction is an essential agricultural practice for improving soil structure and promoting crop growth. The DT soil loosener and decompactor is designed to penetrate deep into the soil, between 30 and 60cm, and break up compacted layers.
Here are some tips for optimal use:

Choose the right time: It is best to decompact the soil when it is slightly moist. Soil that is too dry or too wet can make the operation less effective.
Adjust the working depth: The decompaction depth must be adjusted according to the type of soil and the crop in place.
Avoid repeated passes: A single pass is often sufficient to achieve the desired results. Repeated passes can damage the soil structure.

Agronomic benefits

The action of DT soil loosening and decompaction machines brings several benefits to soil life:

Improved soil structure: By breaking up compacted layers, the soil loosening machine allows plant roots to develop more easily and access a greater quantity of nutrients.
Improved water infiltration: Decompacted soil allows for better water absorption, reducing the risk of erosion and runoff.
Reduced mechanical resistance: Plant roots encounter less resistance, promoting faster and more vigorous growth.

Press again to maintain moisture.

After mixing and loosening the soil, it is advisable to lightly reconsolidate down the soil. This action not only stabilises the soil, but also helps to retain moisture. Indeed, well-consolidated soil limits water evaporation, thus allowing for better retention of the moisture essential for plant growth.
The double roller levels the soil surface after the tines have passed. Thanks to its integrated bearings, it prevents vegetation from wrapping around the bearings. The horizontal adjustment of the front and rear rollers using a spindle allows you to increase the pressure on one of the two. In addition, increasing the distance between the rollers simplifies work on stony ground.

Performance and Robustness: a Perfect Combination

Las gamas DT L y XL están disponibles con anchuras de trabajo de 3 y 4 metros.

A model tailored to each farm

The DT L 300, with a width of 3 metres, is designed for light soils and tractors up to 230 horsepower, allowing for working depths of up to 50cm. The DT L models feature large underframe clearances (780mm in T and 870mm in NSH) and wide distances between tine rows (800mm in T and 850mm in NSH), ensuring clog-free working even in the presence of residues.

The DT XL, in fixed 3- and 4-metre versions, is suitable for heavy soils and high-powered tractors up to 400 horsepower, for depths of up to 60cm. The DT XL offers high throughput thanks to its underframe clearance (920mm in T and 1000mm in NSH) and distances between rows of tines (870mm in T and 1000mm in NSH).

The tine : the heart of the machine

Two types of safety devices are available for the tines. The first option is mechanical safety via a traction bolt (T), offering a point force of 3,550kg for the L tine and 4,370kg for the XL tine. The second option is NSH safety, allowing the trigger pressure to be adjusted between 165 and 190 bar, with a maximum point force of 1,190kg for the L tine and 1,670kg for the XL tine.

The tine plays a central role in breaking up the soil, which is essential for good ground preparation. The explosive wing tine, with a width of 350mm, offers two wing height positions. It is equipped with a splitter triangle and a 70mm quick-fit point, also available in a carbide version, for maximum efficiency in breaking up the soil.

Maximum adaptability : a point for every type of soil

70mm ripper points are available on DT models in Standard, DURAKUHN or DURAKARB versions. Their robust design and ability to effectively break up soil make them the top choice for improving soil structure and promoting crop growth.

DURAKUHN: DURAKUHN points are designed to withstand wear and tear and the most demanding working conditions. Thanks to their tungsten carbide coating, DURAKUHN points ensure effective soil cracking, allowing for better aeration and optimal soil preparation.

DURAKARB: DURAKARB points, on the other hand, feature a full carbide coating, which gives them increased abrasion resistance and a longer service life. This carbide coating allows DURAKARB points to maintain their effectiveness even in the most abrasive and hardest soils.

Hay tres tipos diferentes de puntas disponibles en la gama DT: estándar, DURAKUHN o DURAKARB (mostrada aquí).

A machine that is easy to adjust and maintain

El DT cuenta con ajustes hidráulicos sencillos y rápidos, especialmente para controlar la profundidad de trabajo.

Hydraulic adjustment of working depth

The DT subsoiler is equipped with a continuously variable hydraulic adjustment system. This system allows the working depth to be adjusted smoothly and without interruption, ensuring optimal adaptation to ground conditions.

Thanks to the continuously variable hydraulic adjustment, the operator can easily modify the loosening depth according to the specific needs of the crop and the characteristics of the soil. This feature is particularly useful for working in a variety of soils, from light to heavy, ensuring maximum efficiency and uniform ground preparation.

The hydraulic depth adjustment system also maintains constant pressure on the tines, ensuring uniform soil cracking. In addition, the continuous hydraulic adjustment reduces component wear and increases machine durability, providing a reliable and long-lasting solution for users.

Low maintenance

The DT L subsoiler is designed to deliver exceptional performance while minimising maintenance requirements. Thanks to its robust design and the use of high-quality materials, the DT guarantees increased durability and reliability, thereby reducing maintenance interventions.
The DT's components, such as tines and bearings, are manufactured to withstand wear and tear and the most demanding working conditions. This resistance extends the machine's service life and reduces the frequency of part replacements. In addition, the integrated hydraulic system is designed to operate smoothly and efficiently, requiring little maintenance and ensuring consistent performance.
Farmers can thus benefit from reliable and durable equipment that requires less time and resources for maintenance, allowing them to focus more on optimising their crops.
