A vegetation cutter has a power unit and a rotating cutting device defining a planar cutting circle. In a hand-held cutter the circle is disposed about an axis at an obtuse angle with respect to the structure held. In a non-hand-held unit the axis is not dependent on any relationship to the structure. For either of these categories, a guard is provided having a narrow elongate arcuate shape, the arc centered on the axis with radius substantially the same as the planar cutting circle and normally disposed below the planar cutting circle and in front of the cutting circle with respect to the forward movement of the cutter and the operator thereof. The guard has sufficient length to operatively support and guide the cutting device when the cutter is turned and operated with the planar cutting circle in vertical disposition as in edging. A mounting assembly is secured to both the structure and the guard and permits the guard to be pivotted from normal operative position to standby position. |
