ABSTRACT:
A rotary blade for use on a cultivator or rototiller. The blade comprises two disk-like members mounted on a hub having a central axis and a central opening to mount it for rotation about that axis. Each disk-like member has ten tines projecting generally radially outward. When viewed from the side each tine is generally triangular and has a pointed free end. One of the tines of each disk-like member is planar and is disposed parallel to a common plane located between the disk-like members and perpendicular to the hub, while the other nine of the tines of that member are bent or curved with respect to the common plane. In particular, three tines bent parallel to respective bend lines in a simple curve so that the respective free ends curves inward toward the common plane. Three other tines are a bent parallel to respective pairs of bend lines in a compound or serpentine curve having a first portion curving outward away from the common plane and a second portion curving inward toward the common plane. Three other tines are bent parallel to respective bend line in a simple curve so that their respective free ends curve outward away from the common plane. The disk-like members are mounted on the hub so that the pointed free ends of one member are interposed between the corresponding pointed free ends of the other member. The bend line(s) of each tine is (are) oriented at an angle of approximately seventy-two degrees from a radius extending from the central axis to the tip of the tine.
