STIHL SR 450 Backpack Mistblower / Sprayer

Powerful Spraying and Dusting for Large-Scale Work

The STIHL SR 450 Mistblower is built for users who need reliable performance when treating large outdoor spaces with liquids or granules. Its advanced 2-MIX engine provides strong spraying reach up to 14.5 metres, allowing you to cover wide areas quickly and with impressive accuracy. This extended reach makes the machine ideal for orchards, estates and other environments that demand confident and efficient application. The large 14-litre tank offers longer working time with fewer refills, supporting steady and uninterrupted progress during longer tasks. This combination of power, range and capacity ensures productive work even in challenging conditions.

Quick and Simple Switching Between Modes

The SR 450 features a practical 2-in-1 conversion system that allows fast switching between spraying and dusting, helping you adapt to different tasks with ease. This mechanism requires no tools or technical adjustments, which makes conversion simple for all users. You only need to remove, turn and reinstall the tank to change modes, allowing you to continue working without delays. A metering lever is located just below the control handle, giving you precise control over application levels using one smooth movement. This allows finer regulation of liquids, powders or granules, supporting consistent coverage across every session.

Adjustable Spray Patterns for Improved Coverage

Three removable grids allow you to tailor airflow and spray patterns to suit your surroundings. These grids help you achieve accurate spray direction and shape, supporting efficient work around trees, large plants and uneven terrain. Whether you need a narrow flow or wider dispersion, the included grids help you adapt quickly. The large filler opening ensures faster refilling with reduced spillage, while its wide design also makes cleaning the tank much easier. These thoughtful features help maintain tidy, controlled and productive application throughout the day.

Comfortable Design for Reduced Fatigue

Comfort is central to the SR 450’s design. The multi-function handle provides easy one-handed control, giving you immediate access to all essential functions whether you are right- or left-handed. STIHL’s ElastoStart technology helps reduce starting shock, creating smoother and easier starts with every pull. Anti-vibration elements help minimise engine movement at the handle, delivering reduced fatigue during long periods of use. The padded carrying system distributes weight evenly across your shoulders and back, offering greater comfort during extended spraying tasks. This balanced design helps you work longer without strain.

Reliable and Efficient Performance for Outdoor Treatment

The SR 450 is engineered to deliver consistent performance during demanding outdoor applications. Its smooth operation, strong reach and simple adjustments make it a dependable solution for many treatment tasks. The powerful airflow supports accurate misting and dusting, while the clever design ensures efficient and comfortable operation throughout every job. Whether managing orchards or maintaining large gardens, the STIHL SR 450 Mistblower provides reliable, precise and user-friendly performance that supports professional-level productivity.
