Abstract

The harrow has a transverse coupling bar which draws plane blades which are parallel to the bar and rearwardly inclined so that their lower edges precede their upper edges. The blades are carried by frames which are pivoted to the bar so they can follow unevenness of the ground. The blades are mounted in pairs on their frames and these are spring loaded against the ground so as to distribute the load evenly between them. Harrows are mounted on frames behind the blades and pivoted to the bar and spring loaded to the ground.
