摘要：
A residue management tool mountable to a frame of a seeder for cutting or clearing residue on the ground is provided, comprising a pivotable arm having a proximal end and a distal end, the proximal end of the pivotable arm adapted to be directly or indirectly pivotally attached to the frame； a rotatable cutting or clearing device operably mounted to the distal end of the pivotable arm and operative to cut or clear the residue on the ground； a biasing device operative to exert a downward bias force on the pivotable arm to engage the rotatable cutting or clearing device with the ground； and a depth restraint operative to prevent the rotatable cutting or clearing device from over-penetrating the ground.
