Improving the Design of the Disc Harrow for Berry Plantations

Introduction. Reducing the distance of throwing soil into zone around bushes and maintaining a leveled surface between rows berry crops are urgent scientific problems. Aim Article. To identify basic parameters for interaction spherical disk with waterlogged on this basis to develop technical solution reducing away in space crops. Materials Methods. The object research is an orchard disc harrow equipped protective shield mounted front outermost tool panel. subject process end plate plantations. length its spatial orientation were chosen as optimization field experiments. quality evaluation intertillage plantations was carried out by profiling their surfaces. Results. Based results theoretical studies, it found that angle inclination horizontal plane should be within 53–54°, respect movement – 50–58°. experiments have confirmed conclusions. It has been established only shield, which 450 mm installation 50°, allows completely eliminating side throw beyond width tool. In addition, these ensure stable operation almost any moisture weed infestation bushes. Discussion Conclusion. use modernized tillage made possible exclude bush increase speed unit 25%.
