ABSTRACT:
A sod cutting knife having a horizontal undercutting blade, vertical support arms connected to each side of the undercutting blade, and removable side cutting blades mounted at the front of each support arm. The side cutting blades project below the bottom of the undercutting blade to protect the connection between the undercutting blade and the support arms against wear. The vertical and horizontal extent of the protrusions of the side cutting blades below the undercutting blade is limited to avoid undue resistance to vertical movement of the knife into the ground.
