Stihl SR 450 Blower/Sprayer
A powerful backpack sprayer/duster that easily converts from liquid to granular applications.
Product Code: SSR

For both the distribution of liquid or solid insecticides, fertilizers, or herbicides, the low-emission, fuel-efficient STIHL SR 450 Backpack Sprayer has a larger, more powerful engine that provides a spray range 20% wider than previous models, taking 20% less time to spray the same area, depending on application. The SR 450 easily converts from misting to dusting applications without special tools or additional equipment, 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.
