By loosening and aerating the soil, the machines activate soil life and thus support the build-up of humus and therefore also CO absorption. we have customers who already sell CO2 certificates due to their proven humus build-up.

‍

The fact that the front subsoiler, the rear subsoiler or the KR with TL shares open the soil downwards through fine hairline cracks increases the water absorption capacity and the water retention capacity enormously, so that virtually any amount of water is absorbed by the soil (and remains available to the roots), thus preventing waterlogging.

‍

DUTZI machines, especially the FL or HL, are not only effective in heavy rain and waterlogging, but of course BEFORE heavy rain. A field cultivated with an FL or HL can absorb almost unlimited amounts of water, so that waterlogging, flooding or erosion no longer occur during heavy rainfall.

‍

In principle, the FL can also be used on stony ground. If there are large boulders on or under the fields, you should drive with appropriate care. Users have already removed large boulders from the ground with the FL.

‍

Basically, if you can "afford it", choose the chisel rotor because the chisel rotor is much more durable and less prone to wear. Anyone who does not have too many stones can "afford" the chisel rotor.

Otherwise, you should opt for the tine rotor: The" tines of our rotors hit the stones vertically from above and push them down or crush them. However, the tine wears out during its work - the more abrasive the soil, the more it wears out.

There are users who switch to the chisel rotor after a few years with the tine rotor because they then actually no longer have any stones on the horizon in which they are working.

‍

TL coulters consist of the same tool that is used on the front and rear loosener and a slightly forward-bent handle. As an alternative to the delta coulters, the TL coulters are mounted in exactly the same position. They work in a similar way to the FL or HL, even if they are not quite as flexible in terms of depth control because they are fixed to the rotor.

‍

In fact, anyone who wants to work their soil less intensively should switch to the TL coulter or the FL. However, some people still want to "work deep once" and cut wide areas. The delta shares are used to drive under the plough or other compaction base, lift it up and throw the material into the rotor chamber for crumbling.

‍

The delta coulters are part of the "old" DUTZI system. There are still many farmers who have been working well with the system for decades and are keen to continue using delta coulters. However, we have an increasing number of users who are switching to the FL or at least the TL coulters.

‍

The delta shares pass under the plow sole across the entire working width and ensure that all the material thrown up is loosened in the trailing rotor.

If less material is to be moved and as much of the existing soil structure as possible is to be retained, there are actually no advantages of the delta shares over the front subsoiler or over the so-called "TL shares", which work with the same tools as the front and rear subsoilers and are a very good, inexpensive alternative to a front subsoiler. The depth effect of the TL shares or the FL is simply much greater than that of the delta shares. At the same time, much less soil is moved. This also significantly reduces the power requirement.

Friedhelm Dutzi and two other developers developed the first tine rotors at the end of the 1970s. Friedhelm Dutzi then consolidated the know-how at DUTZI in the early 1980s. Of course, Friedhelm Dutzi already had the idea of a ploughless one-pass method back then, but he was not yet familiar with the front loosener, instead working with the so-called "delta shares", which were mounted directly in front of the rotor. They drove under the compaction base, lifted the soil slightly and fed all the material into the rotor for crumbling. The delta shares often went 40 cm deep into the soil, sometimes even deeper, and the rotor worked 13-18 cm deep into the soil at that time. Nowadays and with the "new system", i.e. the KR with the FL or the so-called TL shares, we recommend driving the rotor only approx. 5-8 cm deep in the soil.

DUTZI machines, especially in the combination of front subsoiler and KR, stand for solid, sustainable, conservation tillage with a special depth effect. DUTZI works "with and not against nature". In order for the soil to develop optimally, the soil must not be worked too quickly, for example. The recommended speed is 6-8 km/h so that the soil has enough time to form hairline cracks. These hairline cracks will then continue to develop over the next 1-2 weeks. If you drive too fast, i.e. over 10 km/h, this cracking effect is generally not created. The DUTZI combination therefore "forces" the user to drive a little slower and not so low in order to achieve the optimum result, which also saves fuel at the same time.

The DUTZI system thus makes a lot possible: it aerates the soil and activates soil life, it loosens the soil and enables significantly stronger root growth, and it dramatically increases the water absorption capacity and water retention capacity of the soil by introducing and forming the hairline cracks, so that the roots are usually always supplied with sufficient water until harvest.

The DUTZI system is at the same time only one, albeit the first and very important building block in a whole chain of measures to recultivate a soil or simply make it even better. Other important components are the right crop rotation, catch crops and constant soil cover.

Ideally, organic fertilizer is also applied, which can then be optimally worked into the soil by the DUTZI KR.

The DUTZI system is essentially a "one-pass system". We want to complete a whole series of work steps with one pass: deep loosening without destroying the soil structure, superficial, coarse crumbling, usually between 5 and 8 cm working depth, sowing - with a mounted seed drill - and reconsolidation by the trailing, blockage-free roller. This saves time, fuel, emissions and wear, and the number of working machines can even be significantly reduced.

‍

No. If the front subsoiler is used correctly, the tools clearly work downwards, much deeper than the approx. 20 cm that the pressure of the tractor's 4 tires compacts again. The top layer is loosened again by the rear machine. If the DUTZI KR is driven at the rear, a working depth of 5-8 cm is sufficient.

‍

DUTZI machines are extremely robust. The KR and its derivatives work with gearboxes that are just as robust and powerful. Many of our machines run just as well after 30 years as they did on the first day. As a result, our machines are very rarely scrapped, but still achieve comparatively high sales prices even after decades, for example when they are sold due to farm abandonment. The supply of spare parts is also generally guaranteed, even for machines that are almost 40 years old. It may be, for example, that we no longer have every gearbox drawing. In the worst case, a gearwheel may have to be rebuilt "from a sample".
