        <p>The article presents the results of experimental studies on determining the effect of the vertical loading applied to a double-disc coulter of  seed drill on uncultivated soil, i.e., the depth of the seeding furrow opened by the disc seeder coulter and its average square deviation, and the resistance to traction of the seed drill coulter. According to the results of the research, it was determined that the vertical load given to the double disk coulter should be at least 250 N in order for the seeder to plant repeated crops on uncultivated soil to work at the level of existing agrotechnical requirements.</p>

        <p>В статье представлены результаты экспериментальных исследований по определению влияния вертикальной нагрузки на двухдисковый сошник сеялки на необрабатываемой почве, а именно глубины посевной борозды, открываемой дисковым сошником сеялки, и ее среднеквадратичного отклонения, а также тягового сопротивления сошника сеялки. По результатам исследований определено, что для того, чтобы сеялка для посева повторных культур на необрабатываемой почве работала на уровне существующих агротехнических требований, вертикальная нагрузка, прикладываемая к двухдисковому сошнику, должна быть не менее 250 Н.</p>

Tadqiqot natijalariga ko‘ra, ishlov berilmagan tuproqqa takroriy ekinlarni ekish uchun mo‘ljallangan seyalka mavjud agrotexnik talablar darajasida ishlashi uchun ikki diskli soshnikka beriladigan vertikal yuklama kamida 250 N bo‘lishi kerakligi aniqlandi.</p>
