Abstract

Zero tillage technology, including mechanical chopping of plant residues, is used in order to create the most favorable conditions for the people’s rest in the park zones, and to improve fertility of the fields. The article describes the need of a new class of equipment for zero tillage – a chopper on the basis of moto chassis, and justifies the relevance of the proposed arrangement for the intended conditions of use. Other versions of these choppers in the form of attachment to the tractor are also considered; some disadvantages of this type of equip-ment associated with the complexity and high cost of its transportation to the place of work are established. An important technical difference from the modern equipment, having a tool driven by the PTO, in our case, is that the actuator is driven by a self-contained engine of the chainsaw "Ural MP-5 Electron". This allows us to calculate separately the chassis fuel economy when driving and the tool engine while chopping. The paper presents a mathemat-ical model of fuel efficiency of the self-propelled cutter of the plant ground cover in the aes-thetic forestries and fruit farmings. A two-wheeled version of a wheel formula 2x1 is con-sidered as the base chassis. A rotary actuator of a chopper having 16 L-shaped knives, self- driven by an internal combustion engine (designed drum operating width is 0.5 m; operating speed is 1900 min-1) is investigated in the model. The provisions of the method of statistical dynamics of linear stochastic systems and discrete optimization are used in the process of mathematical modeling. We made the conclusions about the optimization problem solution to minimize the proportion of technological fuel consumption during chopping of ground biomass – leaves, grass stems, small roots and twigs.
