SR 420 petrol-driven mistblower: professional power tool with a very long range

The STIHL SR 420 backpack petrol-driven mistblower offers fruit growers, winemakers and farmers a particularly wide spraying range for the application of fluids. The transparent spraying agent tank takes 13 l of spraying agent and can be refilled without spillage through the large filler opening. The powerful petrol engine produces a spray jet that extends a long way, both horizontally and vertically, while the single-handed multi-function handle enables you to operate the mistblower easily and safely with one hand. The STIHL anti-vibration system protects your muscles and joints while spraying. Another comfort-enhancing feature is the carrying system with comfortable straps. This makes your work easier by distributing the weight better on your back.

The STIHL SR 420 mistblower can also be used as a blower or, when combined with separately available kits, as an atomiser with increased range. For example, a can be used with the machine to apply very small quantities of liquid in a targeted manner.
