Course abstract

The aim of the course is to get acquainted with the working environment and work object of agricultural machinery: soil, stalked, liquid, pouring, absorbent, biologically active, chemically aggressive materials; technologies of agricultural operations: regimes, energetic and costs; conditioning and storing of plant production; constructions of machinery: agritechnical requirements, technological parameters, technological and kinematic scheme.

Learning outcomes and their assessment

Knowledge: of technical crop harvesting machines as a tool for the implementation of a complex process, to orientate in the offer of technical crop harvesting machines, technologies and applicable machines and equipment.
Skills: to evaluate the work to be performed with technical crop harvesting machines, to choose the technological and technical solutions for the operation of the applied equipment. 2 laboratory works, report and work defense are planned. Tests.

Competence: to competently know the issues of technical crop harvesting machines, independently choose appropriate technologies and equipment for their implementation, as well as manage work with appropriate equipment. 1 laboratory work, report and defense of the work is planned. Test.
