The Results of Field Test of the Mounted Attachment CHD-3

Abstract

One of the ways of achieving landing accuracy is the control of the unit movement using navigator installed on the tractor, including autopilot systems that can correct the trajectory of the tractor. However, the straightness of tillage may be low. (Research purpose) The research purpose is in increasing the track stability of agricultural tools when cultivating row crops. (Materials and methods) The article proposes the use of a controlled attachment as part of a machine-tractor unit with navigation equipment installed on both a tractor and an agricultural tool, the use of which will significantly improve the accuracy of technological operations. The article presents the scheme, technical characteristics, and operating principle of the controlled attachment device. The article describes the method of conducting a field test of a machine-tractor unit with an installed controlled attachment. (Results and discussion) It was found that when cultivating without navigation equipment, the deviation from the axis was 62 mm; when cultivating with a machine-tractor unit with navigation equipment on a tractor it reaches 22 mm; when cultivating with a machine-tractor unit with a controlled CHD-3 attachment and navigation equipment on a tractor and cultivator it reaches 20 mm. The untreated area of the field by a machine-tractor unit with CHD-3 and navigation equipment on a tractor and cultivator was 0.27 square meters in relation to 0.45 square meters when processing the unit as part of a tractor with navigation equipment and a cultivator. (Conclusions) The use of tool control devices for cultivating rows of potatoes is impractical, since the straight movement of the planting machine along a given line is not guaranteed when planting potatoes. It was found that increased accuracy and further productivity will be achieved when using a controlled attachment on all operations of potato cultivation up to harvesting. The use of a controlled attachment device is advisable when cultivating crops that require high precision planting, for example, sugar beets.
