<p>A brush cutting blade (10) has a curved slitter type/non-raker type primary cutting tooth (16), and a preceding appendage (18) forming a combination depth gauge and small stem slitter. The primary tooth (16) terminates over the blade body, with the cutting edge (22) provided by that curved portion of the tooth between its most lateral point (24) and the point (28) of termination over the blade body. The cutting edge (22) is curved but outwardly directed in a slitter configuration throughout its length. The lateral point of the cutting edge determines the kerf width to prevent binding. The slitter cutting edge (40) of the appendage (18) is hook shaped to cut small willowy-type stems and the appendage has an upper inclined guide edge (38) that guides larger rigid-type stems to the primary cutting tooth (16). The uppermost point (36) of this guide edge of the appendage provides a depth gauge for the primary cutting tooth.</p> |
