Abstract:
In grassland areas, there is a trend to large-scale farms. In comparison to historical agriculture with its high number of agricultural employees, the large farms today are mechanized with high-performance machinery. The labour productivity increased. Larger grassland machineries cannot well adapt to harvested grass material and to the uneven areas. The homogeneous management of heterogeneous grassland can create some specific problems (forage contamination, shatter losses). In this master thesis the status quo of the grassland mechanisation is presented and discussed. In an online-questioning to the Austrian grassland farmers, the benefits of the variable impulses and variable settings in grassland machines are investigated. The questionnaire was structured in a general part and specific part with 27 questions. 56 farmers have filled the online- questioning. More than half of the interviewees are inspired of these systems. 80 % of the farmers would prefer an electric or hydraulic impulse to the mechanical impulse. Only 10 % of the interviewees have no interest in variable systems. The grassland-machines which cause the highest forage contamination and shatter losses according to literature are classified by the questioned farmers as a little worthy of improvement. A clean and forage protective harvest of grass requires variable drives and setting in grassland machines. Research and development in this area will increase.
