The main source of roughage - grasslands that cover more than one third of all agricultural land of the Republic of Belarus, which is about 3.000.000 hectares, but the predominant part of meadows and pastures is in disrepair status and has very low productivity. There are two ways of improvement of pastures and hay fields: fundamental and superficial. When the radical method of farmland improving is applied, natural vegetation have been completely destroyed by plowing, milling, heavy disking and creating seeded hay or pasture. Surface improvement involves hay mowing at the optimum time and the rational use of pastures, which provides 10-25% yield increase without any additional cost. In this method, shredding of animal wastes, destruction of bumps and bushes, mowing and chopping of stemmed weeds comes around. Using a mower-shredder meets the legal requirements for mowing and grinding stemmed vegetation. In the article foreign experience of application of the mower-shredders of different species is evaluated, their advantages and disadvantages are outlined. A model of rotary mower, radically new for Belarus, with blades of high efficiency is suggested. Diagram and detailed description of the mower is presented and analyzed, the main advantages of its use are listed.
