AB  - To implement the proposed technology for chopped hay and haylage harvesting, the universal
pick-up chopper equipped with a hammer-knife working elements and a new picking mechanism without a
treadmill has been developed. The use of the technology for harvesting of chopped coarse forage provides a
reduction in specific operating costs by 2.45 times compared with the technology for harvesting of pressed
forage. The goal of the research is the development and implementation of the proposed technology and
universal pick-up chopper which reduces operating costs, improves the quality of chopped coarse forage. To
theoretically justify the picking up process with a picking mechanism without a treadmill, the methods of
theoretical mechanics were applied. In order to determine the optimal parameters of the pick-up chopper,
one-factor experimental researches were used. As a result of theoretical studies, analytical expressions were
obtained for determining the forces acting on the forage when lifting it up with the fingers of the pick-up. The
values of the resultant forces were determined and the possibility of operating the mechanism without
disturbing the technological process of selecting coarse forage was justified. All this proves the reliability of
the obtained analytical expressions. As a result of experimental researches and laboratory-field research tests
we determined that the universal pick-up chopper, equipped with a new picking mechanism with hammer-knife
working elements, provides harvesting of chopped hay with a capacity of 9.0-9.5 t/h and haylage with a
capacity of 5.83-7.56 t/h.
