FIELD PERFORMANCE OF THE ROTARY PRICKLE CHAIN TILLAGE TOOL

One of the effective farm practices of moisture accumulation is the pre-seed harrowing in early spring. A rotary prickle chain tillage tools are the most suitable for this agricultural practice. However, the process of their interaction with the soil has not been drawn a research attention. Hence, this research was aimed to field investigation of the performance of the developed rotary prickle chain tillage tool for the pre-seed harrowing. In this paper the field performance of the developed tillage tool in terms of the work quality and specific draught resistance are presented. The obtained data allowed us to determine the parameters and operation modes of the developed tillage tool under which the required quality is provided. The research results will be used in the development of the implement for the pre-seed harrowing
