FLEXIBLE HARROW Russian patent published in 1995 - IPC

FIELD: agricultural machine engineering. SUBSTANCE: flexible harrow has a traverse beam with the chain drag 3 and a strut, rigidly secured to it. The chain drag 3 has two parts 29 and links with cultivating teeth. A telescopic rod with a disc cutter is jointly arranged on that strut. An end of each part 29 of the chain drag 3 is jointly connected with an axis of the disc cutter. The disc cutter is joined with the rod by a stopper; members of the rod are spring-loaded one relative to another. Upon motion of the flexible harrow the teeth of the drag 3 perform breaking of soil lumps and clods, the disc cutter provides slow down of the chain drag 3, increasing disintegration degree of the soil lumps. EFFECT: enhanced quality of soil tilling at working with increased speeds. 2 cl, 8 dwg
