The challenge:

The TopCut tool carrier for climate-adapted cultivation. The farmer can choose various tools to suit the conditions.
The subject of soil tillage is gaining more and more significance in the purchasing process ifor farms. The bigger the problems with lack of moisture, chemical resistance and the requirement for reducing the amount of plant protection agents, the more important the correct soil tillage becomes. A particular emphasis is placed on the initial stubble cultivation. This is precisely where the biggest challenge lies. On the one hand, we need to produce the optimum seedbed for accumulating volunteer cereal and weed seeds. This means that undesirable growth can be accumulated directly after stubble processing and then be combated mechanically in the second processing pass. Ultra-shallow processing with optimum germination conditions for the stray cereal and weeds and grasses is of extreme importance, particularly with regard to old rape growth, and in the problem areas of black grass and loose silky bent. 

In addition, rotting of organic matter is of enormous significance for field hygiene. Good rotting reduces the transfer of fungal disease and pests. It is therefore important to make sure that cutting or preparation of the organic matter be already undertaken during the initial processing.

On account of the increasing dryness of the summers, it is important that evaporation be reduced and that water be saved. For this reason, it is important to work only as deep as is necessary in the initial pass.

The solution: TopCut tool carrier for ultra-shallow soil tillage

AMAZONE has started the TopCut development project to accommodate this increasing requirement for ultra-shallow soil tillage, and this will be presented to the public at the AGRITECHNICA 2022 exhibition. The challenge in this project was the development of the optimum tool combination for ultra-shallow soil tillage. The following aspects were taken into account:

  • Organic material should be shredded to aid the rotting process
  • Adequate fine soil should be generated for optimum germination conditions
  • Working should be as shallow as possible - no burying of seeds and reduction in evaporation
  • Perfect soil adaption of the tools is a prerequisite
  • Straw post-distribution should be carried out if required
  • Under dry conditions, good consolidation is required for optimum germination conditions

Soil tillage which has a range of different tools available to the farmer to suit the operational requirements is needed to meet all these requirements in various crops.
As a result, the first TopCut 12000-2 tool carrier with a working width of 12 m and various tools started field trials in the summer of 2021.

Various different tools for ultra-shallow processing

Alongside the classic deployment after rape, catch crops or sunflowers, where a combination of a double knife roller and a harrow or roller is used under optimum damp soil conditions, we also intend to develop tools that produce sufficient fine soil under dry conditions and in cereal stubble for optimum germination conditions.
The TopCut consists of three successive tool segments that can be equipped with various different tools to suit the customer’s needs and requirements. So the toolbar may be a single knife roller, a crushboard or a wavey disc. The double knife roller then operates in the main tool area. As an alternative, however, you can use double wavey discs or a combination of wavey discs and knife rollers. We intend also to include various different spading discs and star discs in the tests. The wavey, spading and star discs cultivate the soil only to a minimum extent, but, on the other hand, they produce fine soil for optimum germination conditions.

Consolidation or harrow

Under dry conditions, it is an advantage if the lightly workedsoil is pressed down again. Here we have the option of using the TopCut with a roller, such as the KWM 650 wedge ring roller with matrix profile. In addition, you can also run a single row harrow element in front of the roller. As an alternative to the roller, you can also install a three-row straw harrow as the trailing tool. This provides post-distribution of the straw and also shakes seeds out of the straw, the pods or the ears.

Successful practical experience

TopCut with three-row straw harrow in rape stubble

In 2021, the TopCut 12000-2 ran with various different tool combinations on various different agricultural operations, under the most varied of conditions. This was supplemented by a field trial carried out with the University in Bernburg on rape and wheat stubble, to assess the tool combinations with regard to growth behaviour, shredding effect, working depth and other parameters. 

Results so far demonstrate the benefits of the TopCut tool carrier:

  • Ultra-shallow soil tillage with a high proportion of fine soil for perfect germination conditions, even on cereal stubbles
  • Markedly reduced evaporation compared with other processes
  • Optimum consolidation for reliable regermination
  • Perfect shredding effect in rape, sunflower and maize stubbles and in catch crops
  • High output with low fuel consumption

In 2022 we will be building more machines to gather more experience with various different tool combinations in diverse operations under various different conditions.
