摘要： 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.

摘要： Apparatus for forming an above ground bed in which plantlife may be grown and for irrigating the bed. The apparatus comprises a plurality of modular members arranged to be readily connected to one another to form a walled enclosure disposed on the ground. The enclosure is arranged to be filled with a plant growing medium, e.g., soil, to form the bed. Each of the members is an elongate hollow body having a pair of ends. At each end is a releasable connector portion which is arranged to releasably connect the members to one another at various angles to form enclosure of various shapes. Each of the members includes an inner wall having a plurality of small apertures which are in communication with the hollow interior of the member. At least one of the members includes a fitting for a hose to enable water to be introduced therein. The connectors include couplings which allow water introduced into one member to flow into the other members, whereupon the liquid may slowly seep out of the apertures and into the bed to irrigate the bed. The members also include openings extending through them to enable them to be staked to the ground. A recess is provided in the top wall of each member at one end thereof to enable auxiliary structures, e.g., trellises, frames, etc., to be mounted thereon. The staking openings can also be used for mounting the auxiliary structures.
