Abstract. A design of a cultivator determines the quality of their operation and costs of its implementation. The paper presents the results of theoretical and experimental studies on the determination of a construction arrangement of cultivators, the most efficiently performing seedbed preparation. Today, along with tine cultivators of the traditional construction, the machines, equipped with sweep and disk working bodies, have come into widespread acceptance. To enhance the efficiency of their application for preplant tillage it is necessary to analyze the impact of different ratios of sweep and disk working bodies on the work quality. In this case, you should take into account soil and landscape conditions, where you intend to use the unit. We examined the work of cultivators under conditions of Altai Krai. This goal is achieved by the analysis of construction arrangements, according to which the aggregates for the preplant treatment are made, as well as by the evaluation of the results of their work. For the experimental evaluation we used cultivators KD-720, APK-7.2, KPO-7.2, “Leader 7.2N”. The tests were carried out under the following conditions: loamy ordinary chernozem; soil hardness was not more than 3.5 MPa; moisture content was not more than 25 %; relief was smooth with a slope up to 3 degrees; the infestation with stones missed; the stubble height was no more than 25 cm. The use of combined aggregates, equipped, together with sweeps, by disk working tools, enable to reduce lump content (the share of lumps of soil with a diameter of 25 mm or more) almost 3 times, compared with the cultivators with sweeps only; the surface imperfections – 1.4 times.
Keywords: cultivator, pre-sowing tillage, working tools, operational and technological performances, construction arrangement.
