Objectives The course aims to provide the basic knowledge that enable the student to take the proper choice about technical and economical setting of machines and plants used in forestry, with a particular attention to design, constructive, operational, functional, managerial and environmental aspects, as well as, the required standards in terms of work safety. Practical exercises of a considerable significance related to design and organizational aspects will be achieved.

Dublin Descriptors

Knowledge and understanding:
Acquisition of the basic principles of agro-forestry mechanization, and detailed knowledge of machines and mechanized operations related to forestry.

Applying knowledge and understanding:
Ability to define forestry mechanization plans, select the relevant machines and their combinations in function of technological, structural, environmental and economical constraints.

Making judgements
Being able to evaluate the best technical solutions to employ in order to properly manage working sites.

Communication skills:
Ability to expose the acquired knowledge and to communicate with the technicians and professionals of the sector.

Learning skills:
