A vegetation trimmer with a spool and hub assembly has a cutting filament wound around the spool. The lead terminal is inserted and mounted in the through hole. The modulus is then applied to the result. The stent further includes an integrally molded annular flange located a short predetermined distance proximal to the hemispherical dome. Consequently, the etch proceeds slower near the edge. The device includes a fuel injection device for supplying fuel, an intake air amount adjustment device for adjusting an amount of intake air, an accessory controller for controlling operation of an accessory, a fuel injection controller for controlling a fuel injection amount from the fuel injection device, and an engine stop switch.
