How Does A STIHL Hedge Trimmer Work?

The STIHL hedge trimmer is a straightforward device. The same standards relate to whether you use a corded or cordless model. An extension cord battery or gasoline can power a hedge trimmer. Most gasoline-powered hedge trimmers have a two-cycle engine that requires gasoline to be mixed with oil for the engine to run correctly.

The main advantage of a two-cycle engine is that it has a high torque output while being relatively lightweight. Because hedge trimmers are intended to be handheld, a two-cycle engine is ideal for this application. The ignition switch must be set to the start position before starting the engine. When the starter rope is pulled, the starter engages the drive cup on the flywheel and rotates the crankshaft.

The rotating crankshaft connects to the moving piston within the cylinder, and the ignition process begins. The flywheel contains permanent magnets, and as it rotates past the ignition coil, a magnetic field is created, which induces electricity, allowing the ignition coil to send voltage to the spark plug.

When are you going to trim the hedges you will find a hedge trimmer’s blade made up of two metal, flat shafts that protrude from the device’s body. Each blade has protruding teeth on both sides. They are linked to an electric motor within the body, which when activated causes one or both of the blades to oscillate back and forth rapidly. This results in the cutting action.

Every hedge cutter has two blades. In some models, only one blade moves, effectively stacking one on top of the other to create the scissor action that cuts your hedge. The moving blade creates the cutting action by moving sharply back and forth against the static, fixed blade.
