Course abstract

The aim of the course is to get to know the working environment and the object of the agricultural production harvesting machines: fibrous, loose hygroscopic, biologically active; technologies of harvesting work: modes, energy and costs; crop production storage; machine designs: agrotechnical requirements, technological parameters.

Learning outcomes and their assessment

Knowledge of the application of grain pre-processing and straw harvesting machines as a tool for implementing a complex process; about their offer, technologies and applicable machines and equipment.
Skills to assess the work to be done with grain pre-processing and grain harvesting machines, to choose technological and technical solutions for the operation of the equipment to be used. Skills are assessed in laboratory works, their reports, defense of work and control works.
Competences to know the issues of cereal pre-processing and straw harvesting machines, to independently choose appropriate technologies and techniques for their implementation. Competences are evaluated in laboratory works, reports and defense of works, control works.
