Corrugated blade for tree harvester

Apparatus for cutting a tree comprising:

• a first member;
• a second member operatively coupled with the first member so that the first and second members are relatively movable;
• a first blade mounted to the first member and comprising a first cutting blade body defining a cutting edge, said first cutting blade body defining a plurality of generally parallel elongated ridges, the tops of which are rounded in cross-section, the depressions therebetween each being rounded in cross-section, said ridges running substantially the entire length of the first cutting blade body from the cutting edge thereof, each ridge of the first cutting blade body being substantially uniform in width along its full length, said ridges running to the cutting edge to define a cutting edge the shape of which is determined by said ridges;
• a second blade mounted to the second member and comprising a second cutting blade body defining a cutting edge, said second cutting blade body defining a plurality of generally parallel elongated ridges, the tops of which are rounded in cross-section, the depressions therebetween each being rounded in cross-section, said ridges running substantially the entire length of the second cutting blade body from the cutting edge thereof, each ridge of the second cutting blade body being substantially uniform in width along its full length, said ridges running to the cutting edge to define a cutting edge the shape of which is determined by said ridges;
• the apparatus being positionable so that a tree may be disposed between the first and second blades;
• and,
• means for selectively relatively moving the first and second members to bring the blades into contact with a tree positioned therebetween to cut such relatively positioned tree.
