One of the achievements in the field of growing crop products is the development and implementation of the latest low-cost No-till and Strip-till technologies. On the positive side of these technologies, overnight economic efficiency there are other advantages over industrial technology: the conservation and improvement of soil and environmental indicators, such as the prevention of erosion. Against the introduction of these technologies, there are factors of staff unpreparedness, as well as the availability of expensive special equipment.
Most scientists in the field of agronomy, especially abroad, when new No-till and Strip-till technologies appeared, called them revolutionary in crop production, since along with economic indicators, these technologies preserve the fertile potential of the soil. This is achieved due to less soil damage due to the minimum number of technological operations, as well as the mandatory coverage of the field with plant residues after harvesting. Strip-till technology is most suitable for our area.
The essence of this technology lies in the fact that soil cultivation is carried out selectively, with a strip width of 25-30 cm, and between them there remains untreated strips of 30 cm also, covered with the remains of the crop that was previously harvested. Given the relevance of the topic, this article provides specific material for the study of a tillage machine with active working bodies in the form of mills. The development is based on the well-known agricultural machine, milling cultivator KF-3.6.
The essence of the modernization lies in the fact that the milling heads are placed for processing strips, in front of which there are plane-cutting legs, and behind them are special disks for forming the strip. The main disadvantage of the existing machine is the presence of a bulky drive, which consists of three gearboxes, cardan gears.
In this paper, we consider the option of replacing the drive with a more modern and reliable hydraulic drive.
