Abstract: The invention relates to a vibrating plow blade assembly employing laterally protruding auxiliary blades for cultivating soil beneath the ground surface to form an underground cable channel having non-parallel side walls which exert compacting forces on the cultivated soil about a buried cable in response to compaction activity. A thin coulter blade is used to neatly sever the ground surface to maintain surface disturbance at a minimum.

Abstract translation: 本发明涉及一种采用横向突出的辅助叶片的振动犁叶片组件，用于在地表下培养土壤，以形成具有不平行侧壁的地下缆索通道，该平行侧壁响应于压实活动而围绕埋地缆线对耕种土壤施加压实力 。 使用薄的刮刀来整齐地切断地面以将表面扰动保持在最小。
