BASIC AND PRESOWING TILLAGE TOOL FOR TILLING AGROAMELIORATIVE RIDGE SOIL Russian patent published in 2003 - IPC

FIELD: agricultural engineering. SUBSTANCE: tillage tool has bores arranged in row. Each bore is made in the form of vertical shaft, to which horizontal knives are attached in direction of grooving to the whole tillage depth of soil so that each individual knife operates in soil zone designed for it. Furrow cutting bodies are arranged behind row of bores in accordance with arrangement of furrows. Leveling housing is positioned behind furrow cutting bodies for adjustment in vertical plane. Housing is set at an angle to row of bores for shifting soil ridge from one edge of bed to other edge, where ridge is not formed. Carrier-feeler wheels positioned behind furrow cutting bodies are equipped with device for adjusting wheels in vertical plane. Tillage tool of such construction allows soil to be cultivated by bores to required depth depending on required height of ridges and parameters of previously formed ridges. EFFECT: increased quality of tillage and enhanced reliability in operation. 2 dwg
