Abstract
A cutting blade for agricultural equipment defined by a truncated diamond configuration in plan view, where the cutting blade is made from a high strength plastic material, and where the leading or cutting edges thereof are beveled in a downward and outward direction. In an alternative embodiment, the cutting blade is in a "double diamond" shape, i.e. similar to two truncated diamond shapes at a right angle to each other. In any event, with either invention form, the cutting blade is reversible for extended use. The invention affords particular adaptability to what is presently and commercially known as home trimming and/or edging equipment; however, more far-reaching end purposes are achieved as, for example, the effective cutting of heavy grass, brush and scrub trees because of the unique shape and the material of each cutting blade per se.
