Abstract
A vegetation pruning device (500) includes a pair of pivotably coupled handles (504, 506) and a motor (512) having a rotary output drive for driving an endless flexible cutting chain. A guard is moved relative to the chain by means of pivoting of the handles relative to each other to grip vegetation between the guard and the chain. The motor is actuated by pressing each of a pair of elongate triggers (508, 510) at any position along the length of the triggers.
