Introduction
The HARDI MERCURY mistblower is designed for the application of chemical crop protection products and liquid
fertilizers.
The equipment can only be used for this purpose. Using the mistblower for any other purpose is not permitted.
If there is no particular local law that compels the operator to be qualified in the use of chemical products, it is
highly recommended to be familiar with the basic techniques in the use of chemical products, so as to avoid the
risk of contamination of persons as well as the environment.
Operation of the mistblower can be considered in two parts;
• Fluid Delivery
• Air Delivery
Fluid Delivery
Pump Operation
Pump operation is controlled by the power take-off connection at the tractor. An input shaft on the pump
transmits the rotary motion from the PTO to drive the pump. The output shaft at the rear of the pump provides a
ratio drive of 1:1 to the gearbox input shaft via a secondary driveshaft permanently mounted through a cavity in
the main tank.
Suction
Suction from an external source is available through connection to the suction filter camlock fitting.
Pressure
When the main tank has fluid contents, the pump will provide pressurised fluid for spray operations. The
pressurised flow can be used for agitation and powder mixing or output to the boom controls for regulated spray
application.
