REVERSIBLE PLOW FOR SLOPES Russian patent published in 2000 - IPC

FIELD: agriculture. SUBSTANCE: reversible plow has frame composed of two pivotally connected sections with plow bodies. Rotary frame section has two tubes of round section, which are inserted one inside the other for angular displacement. Tines of right-handed and left-handed plow bodies are rigidly secured to outer and inner tubes so that angle between them is less than 90 and is determined from equation: β = 90^o-α, where β - is angle between plow body tines; α - is angle of slope. Outer tube has elongate radial slots positioned at site of attachment of left-handed plow bodies. Frame rotation section has mechanism for adjusting angle β. This mechanism has graduated sector and lever with corrugated contact surfaces. Lever is built in frame rear part. Plow of such construction may be used for flat plowing without furrows and ridges. EFFECT: increased efficiency by stable plow body depth and improved transverse stability of plowing unit operating on slopes. 2 cl, 6 dwg
