Description
The STIHL SR 450 Petrol Mistblower is a professional backpack mistblower engineered for efficient application of liquid sprays, granules and dust across large working areas. Designed for farmers, fruit growers, estate managers, contractors and grounds maintenance professionals, the SR 450 combines exceptional spraying performance with outstanding operator comfort and proven STIHL reliability.
Powered by a high-performance 63.3cc STIHL 2-MIX petrol engine, the SR 450 delivers 2.9kW of dependable power while reducing fuel consumption and exhaust emissions compared to conventional two-stroke engines. The efficient engine provides the airflow needed to achieve long spraying distances while maintaining excellent fuel economy during demanding applications.
The SR 450 is designed as a true multi-purpose application machine. Its innovative 2-in-1 conversion mechanism allows users to switch quickly between liquid spraying and dusting or granule spreading without tools. This provides outstanding versatility for applying crop protection products, fertilisers, seeds and other treatment materials across orchards, vineyards, forestry and agricultural environments.
A large 14-litre chemical tank allows extended working periods with fewer refilling stops, improving productivity across larger sites. The wide filler opening makes filling quick, clean and straightforward while reducing spillages and making the tank easy to rinse after use. A protective collar helps prevent chemicals from reaching the back padding during refilling.
With a horizontal spraying distance of up to 14.5 metres, the STIHL SR 450 provides outstanding coverage for treating tall crops, shrubs, fruit trees and large planting areas. Three interchangeable spray grids including cone, deflection and double deflection nozzles allow the spray pattern to be adjusted for different applications, helping achieve accurate and efficient distribution.
The convenient metering system is positioned directly below the multi-function control handle, allowing operators to adjust application rates quickly while working. The large dosing lever makes it easy to switch material flow on or off and accurately control the amount of liquid, dust or granules being applied without interrupting work.
Designed for all-day comfort, the SR 450 features an ergonomic backpack carrying system with padded shoulder straps, excellent weight distribution and a breathable backrest that helps reduce fatigue during prolonged use. STIHL’s anti-vibration system minimises vibration transferred to the operator while the single-handed multi-function handle places all engine controls within easy reach for simple operation. STIHL ElastoStart and a manual fuel pump make starting quick and effortless.
A long-life pleated paper air filter provides excellent protection against dust and contaminants while extending service intervals and maintaining reliable engine performance. Built to withstand demanding agricultural and commercial use, the STIHL SR 450 delivers the durability professionals expect from STIHL equipment.
The STIHL SR 450 Petrol Mistblower is the ideal choice for professionals searching for a high-capacity backpack sprayer with long-range application, quick conversion between spraying and dusting and the proven performance of STIHL 2-MIX engine technology.
