ABSTRACT:
The present invention relates generally to brush cutting heads, and more specifically, to protective guard members for cutting tooth assemblies mounted on brush cutting heads. A brush cutting head includes a support body having a first end, an opposed second end and an intermediate portion extending therebetween. The intermediate portion has an outer surface. A plurality of collars is mounted to the support body at spaced intervals along the intermediate portion with each collar extending outwardly from the outer surface. The brush cutting head further also has a plurality of cutting teeth assemblies carried on the outer surface of the support body. Each cutting tooth assembly is associated with at least one collar. Also provided is at least one guard member for protecting at least one cutting tooth of the plurality from impacts with hard objects. The at least one guard member is carried on one of the collars with at least a portion thereof projecting beyond the outermost edge of the one collar. The at least one guard member has an outermost margin which defines a protective envelope that at least partially encompasses the at least one cutting tooth.
