Rotary harrows with supporting member positioned to protect soil working members

摘要

A rotary harrow has a ground engaging supporting member mounted in front of soil working members. The supporting member can be an elongated cylinder that is rotatable or a non rotatable generally cylindrical member that has its largest cross section dimension extending generally parallel to the normal direction of travel. The supporting member can be secured to a frame portion with arms that hold the member close to the soil working member connections with the frame portion. The supporting member can be pivoted or moved within limits responsive to ground irregularities and affords protection to tine connections and associated parts from stones and the like due to its close proximity to these elements.
