Abstract
Abstract A power trimmer including a handle, a housing, a gas operated engine, a plurality of wheels, and a cutting blade. The housing includes a front wheel mounting member, a rear wheel mounting member, and a cutting blade mounting member. The cutting blade mounting member is offset from the front and rear wheel mounting members. A passageway extends along the upper surface of the cutting blade mounting member. The first end of the passageway is positioned adjacent the exhaust port of the gas operated engine. The second end abuts the rear wheel mounting member. The passageway directs the exhaust fumes from the gas operated engine underneath the housing thereby significantly reducing the noise of the invention. Further, harmful exhaust fumes are directed away from the operator. The cutting blade mounting member includes fixed and removable sections. The removable section can be secured to either side of the fixed section. Thus, an operator can trim from both sides of the power trimmer.
