Course abstract

Environment and object of the work 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

After the course studies the student:
Knowledge - able to explain the application of grain pre-processing and grass harvesting machines as a tool for the implementation of a complex process, to orientate in the offer, technologies and applicable machines and equipment of grain pre-processing and grain harvesting machines.
Skills - able to evaluate the work to be done with cereal pre-processing and grass harvesting machines, to choose the technological and technical solutions of the applied equipment operation. 3 laboratory works, report and work defense are planned. Tests.

Competence - able to competently know the issues of grain pre-processing and grass harvesting machines with the acquired knowledge and skills, independently choose appropriate technologies and equipment for their implementation, as well as manage work with appropriate equipment. 3 laboratory works, report and work defense are planned. Tests.
