Disc harrow has disc rows mounted for free lateral movement between end stops

摘要

The disc harrow has a frame (1) on which multiple discs (7) are mounted to engage the soil in two successive rows (3,4) at an angle to the travel direction. The disc rows can be moved into different positions across the travel direction. The discs are free to travel laterally on their supports between end stops. The disc rows can be connected together for rotation.
