STIHL SR 420 mistblower can be used to apply plant control agents and granulate. The standard equipment includes a generous 14 litre tank for chemicals, a level indicator and metering knob on the nozzle, as well as a detachable nozzle with three baffle screens to help with efficient operation.

Power: 2.6kW
Displacement: 56.5cc
Weight: 11.1kg

A large range of accessories for systematic plant protection is available. The ULV nozzle atomises the liquid into extremely fine droplets. The pressure pump ensures that the liquid is always well mixed and prevents segregation, thus maintaining a constant delivery concentration.

The mistblowers can also be converted to spread granulate with the aid of the spreading and dusting attachment.
A simple design concept makes the mistblowers easy to operate. A powerful gasoline engine drives a fanwheel. Air is drawn in through inlets between the powerhead and backplate and expelled at high velocity through the nozzle. The chemical to be sprayed is added to the stream of air before it leaves the nozzle.
STIHL mistblowers offer all the benefits of total portability. They can be stowed easily in a normal car and quickly taken wherever required; this means they can also be used very effectively for smaller jobs that do not justify the time and expense involved in transporting larger machines. Furthermore, they are ideal for applications under difficult operating conditions, such as steep terrain or between narrow rows of plants where tractors can't reach.

Systematic plant control: Standard equipment of units ensures efficient and environmentally compatible chemical application. A metering unit permits infinitely variable adjustment of the discharge rate for more economic use of chemicals. Mistblowers are equipped with a diffuser nozzle. The pattern and direction of the spray can be varied with the help of three push-fit baffle screens:

1 Tapered baffle screen: Liquid chemical is finely atomised in a broad but short cloud of spray. This avoids damage to foliage.
2 Deflector baffle screen: Diverts spray jet at an angle and thus enables low plants to be sprayed underneath.
3 Dual deflector baffle screen: Splits the spray jet in two and thus enables two rows of plants to be sprayed at the same time.
