CULTIVATOR Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: cultivator comprises a frame in the form of horizontal bar 1 connected to which by parallelogram hangers 2 are gangs 3 of working tools. Travel stabilizers 5 of the cultivator are made in the form of -shaped arches whose lower horizontal parts are secured in brackets fastened on adjacent sections 3. Stabilizers 5 are formed by two symmetrical LH and RH parts of -shaped form. These parts are connected by their upper portions which are provided with a row of horizontal holes. In operation, the stabilizers prevent transverse shifting of sections 3 thus ruling out injuries of cultural plants by working tools. They also prevent development of clearances and backlash in parallelogram hangers 2 thus extending the service life of the cultivator. EFFECT: improved design. 2 cl, 6 dwg
