The scope of functions of the cultivator includes: tillage with mills during its preparation for the sowing campaign by leveling its profile and breaking up lumps of earth. As well as care for the soil under the steam, removal of litter and crop residues. With this unit you can cut beds for vegetables and remove potatoes from the field. A quality cultivator can perform work in different climatic conditions with soils of mechanical composition, the hardness of which reaches 1.6 MPa, and the presence of moisture in the soil reaches 30%. How well and productively will be able to perform such a set of works, your chosen cultivator and what types of operations can master the second-hand cultivator, depends on your careful choice.
How to choose the right cultivator
The complex of works requires a universal unit, in which its entire design, rationalism in the ratio of geometric parameters of the frame, the presence of several sections (usually three) and accordingly the arrangement of working bodies in three rows will allow cultivation of the soil carefully with similar overlapping complete pruning of sulfur plants is achieved. Rationality in the design of this trailed unit also makes it reliable and durable, which extends the life of the cultivator. If in the cultivator you have chosen there is enough distance between the working bodies located in rows and between the rows, and also if the frame is planted high - a gleam between a frame and a soil surface - then the cultivator will not constantly hammer and overflow the collected cut plants, passing the field will not be required.
If the cultivator has a reinforced rack (possibly with a spring mechanism) and there is a fairly long lever, arrow type, then loosening the soil will be performed with high quality and to the required depth.
The presence in this model of the cultivator of the mechanism for its fast and convenient transfer to position for transportation will facilitate work and will accelerate movement from the field to the field that will allow to cover the processing of the big areas.
One of such cultivators is the cultivator of continuous processing of TERRA 3 PRO 840, here are its main technical characteristics:
- Type - trailed
- Cutting units - 31 pcs.
- Flat cut paw, grip width - 310 mm
- Equalizers - 4 pcs.
- Skating rinks - 4 amount
- Depth of tillage - up to 120 mm
- Dimensions, mm - 4850 x 8400 x 1150
- The required power of the tractor is from 140 hp.
Types and kinds of cultivators
When determining the choice of cultivator is important to note not only its universal capabilities, but also the right type for the purpose. In general, cultivators are divided into:
- Steam - used for tillage;
- Plowshares - used for loosening the soil and weeding in intergovernmental spaces;
- Universal - are used for continuous and intergovernmental processing;
- Plant feeders - cultivate aisles and apply mineral fertilizers.
In addition to specialization by type of work, this technique is divided into groups according to their weight and, accordingly, power indicators. At the same time light units will be suitable for processing of soils in vegetable growing where the big mobility and small dimensions are more often required. Cultivators belonging to the middle group will cope with the task on relatively large areas. They are stronger in design and are able to withstand heavy loads. Their cutting tools are located at a greater distance from each other, which increases productivity, but makes the design less agile and unsuitable for use in small and narrow areas. Cultivators of the third group - heavy - can work for a long period of time without stopping. They can use various additional attachments and devices, and hence functionality.
Along with the difference in weight of the unit, its capabilities and performance depend on engine power. Therefore, the choice of the cultivator of the appropriate capacity will allow not to waste extra energy resources, without losing the pace of tillage.
The factor that determines quality
The level of quality of land cultivation depends primarily on the correct selection of cutters, which will provide the required depth of cultivation and width of capture during the passage. At the same time for different sites the corresponding mills are required. If the farm has fields of different sizes and widths, then you will need an additional set of cutters that will make your unit more versatile and efficient. If it is necessary to cultivate virgin areas, then mills of a special design will be required. For loams and swampy soils, cultivators with high power are needed, as the required depth of cultivation is up to 30-35 cm.
Design and operational features
Different models of units and drive elements can be used in cultivator models. At a V-belt coupling frequent adjustment and replacement of belts is possible therefore disk coupling looks more favorable and simple in service. And in this regard, the frequency of preventive work with the cultivator, the availability of its individual parts for their processing and so on are important.
Despite the apparent simplicity of this unit, the cultivators may have many distinctive nuances, the presence or absence of which can significantly change the nature of the mechanism and its performance, so do not rely only on information from advertisements, and find out all the pros and cons from a specialist of the supplier company.
