STIHL model mist blower Sprayer Stihl SR 420 Backpack power sprayer

Ideal for distributing liquid or solid insecticides, fertilizers or herbicides, the STIHL SR 420  SR450  easily converts from misting to dusting applications without special tools or additional equipment. A larger and more powerful engine provides a wider spray range that is 20-percent greater than previous models, taking 20-percent less time to spray the same area depending on the application.

The STIHL SR 420  sr-450 Backpack Sprayer is powered by a low-emission, fuel-efficient engine and comes equipped with a large fuel tank, allowing for longer run times during use. Built for efficient operation, the SR 420 one-hand control handle includes engine controls as well as product feed controls, allowing for superior command during use, and air speed can be easily adjusted during use for greater application and less product waste. The SR 450 can also be used as a backpack blower for debris cleanup.
