ASSESSMENT OF THE QUALITY OF THE WORK OF TRACTOR AGGREGATES DURING BASIC TILLAGE

The results obtained in this research indicate that despite the good conditions of exploitation of tractor aggregates, the effects that should be provided by new, modern mechanization during intensive production have not been achieved in practice. According to statistical estimates, 792,000 hectares of agricultural land, 576,000 hectares of arable land could potentially be cultivated in Republika Srpska, and the rest consists of orchards, vineyards and meadows (RS development strategy, 2021). The tractor ZETOR Forterra 1605 with 135 horsepower, i.c. 100.02 kW (power according to ISO 2000/25) was used as the traction-drive unit (Fig.l, Tab.l). Compacting the soil results in an increase in the volume of the soil, which leads to greater resistance of machines during soil cultivation and resistance to the growth of the root system, which absorbs food and water more poorly, which has a negative impact on the yield (Simikic et al. 2018).
