The STIHL SR 450 Petrol Mistblower is a powerful professional backpack mistblower designed for spraying liquids, dusting and spreading granules over large areas. Featuring a fuel-efficient STIHL 2-MIX engine, impressive spraying range of up to 14.5 metres and a convenient 2-in-1 conversion system, it provides exceptional versatility for agriculture, horticulture, landscaping and grounds maintenance applications.

The STIHL SR 450 Petrol Mistblower is a versatile professional backpack mistblower designed for the efficient application of liquids, dusts and granules across large working areas. Combining powerful blowing performance with user-friendly operation, it is ideal for farmers, horticultural growers, grounds maintenance teams and landscaping professionals who need fast, effective treatment of crops, plants and green spaces.

Powered by STIHL’s proven 2-MIX engine technology, the SR 450 delivers strong performance with reduced fuel consumption and lower emissions compared to conventional two-stroke engines. The powerful airflow enables spraying distances of up to 14.5 metres, helping operators cover larger areas quickly and efficiently.

One of the key advantages of the SR 450 is its innovative 2-in-1 conversion system, which allows the machine to be switched from liquid spraying to dusting or granule spreading without the need for complex adjustments. This flexibility makes it suitable for a wide range of agricultural, horticultural and landscaping applications throughout the year.

The backpack design distributes weight comfortably across the operator’s shoulders, making longer working periods more manageable. Ergonomically positioned controls provide convenient operation, while the large-capacity tank helps minimise interruptions for refilling.

Whether applying plant protection products, fertilisers, seed treatments or granules, the STIHL SR 450 delivers professional performance, versatility and reliability in one highly capable machine.
