FR 450 - Extremely powerful 2.1kW-Backpack brushcutter

The loop handled grass trimmers and brushcutters are ideal for working in areas where space is limited, e.g. thinning between bushes and shrubs.

Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened by rubber buffers. This significantly reduces vibrations at the handles allowing for more comfortable and safer operation.

A controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.

The decompression valve is part of the easy start-system. The valve reduces pressure in the cylinder which means less effort is required to start the engine.

STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the users joints and muscles through a spring or rubber element in the starter handle.

It is important to protect your eyes from flying particles and harmful UV radiation. Therefore a pair of safety goggles/glasses are supplied with the the machine. Note: Additional face protection must be worn when working with brushcutters!

A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.

This houses all the engine controls. Easy, comfortable thumb-operated control means the operator's hand never leaves the handle.

Using a STIHL shoulder strap or carrying harness with soft padding makes work more comfortable, particularly during lengthy jobs.
