| Fluid system |
| |
The Hardi fluid system is designed for safe, simple and precise everyday use. The simple design has eliminated the need for any belts or chains, minimizing the risk for a mechanical breakdown.
|
| Pump |
| |
The Hardi diaphragm pumps are designed for the application of crop protection prodcuts and liquid fertilizer. The Arrow is standard equipped with the Hardi 363 Heavy Duty Pump. The 363 HD is specially designed for the abrasive chemicals used in orchards and vineyards. The Hardi diaphragm pumps are:- Self-priming
- Able to run dry without damage
- Easy to service
- Grease lubricated (dry crankcase)
- Mounted with chemical resistant diaphragms and valves
- Positive displacement feature provides a high level of accuracy
- Drain hole allows chemical to drain out in case of diaphragm failure.

| Pressure regulator |
| |
The pressure regulator is centrally located for easy calibration and allows for simple change of application rates. Furthermore, it provides the operator with excellent droplet size control. The 4" pressure gauge is easy to read from the ground or the tractor.
|
| Remote hydraulic spray controls |
| |
The Arrow is equipped with 2 hydraulic valves for left and right on/off. This allows the sprayer to be controlled using the tractors hydraulic outlet. This simple and reliable solution eliminates the need for cables, chemical filled hoses or wires in the cab.
|
| Agitation |
| |
The Hardi engineered tank design combined with the unique dual stage agitation provides the operator with the most flexible and reliable tank mixing system on the market. Hardi dual stage agitation gives the operator the choice of slow moving agitation for foaming chamicals or aggressive fast moving agitation for hard to mix chemicals like most powders.
|
| Two-stage filtration process |
| |
The first filter is the oversized suction filter. The primary role of the suction filter is to protect the pump from damage. The suction filter has a built-in automatic shut off valve, allowing the operator to clean and service the filter with a full tank. The second filter is the pressure filter. The pressure filters provide a clean flow of liquid to the nozzles. Both filters can be serviced and cleaned without use of any tools. The built-in clean water tank provides easy in-field maintenance of all filters.
|
| Nozzles |
| |
The nozzle is the most critical part of any sprayer. The Arrow is therefore stsndard equipped with color coded cermaic hollow cone nozzles on all fan models. this ensures easy calibration and accurate application rates. On axial fans, the nozzles are mounted on single nozzle holders with integrated non-drip valves. Within minutes the operator can change application rate when needed and the non-drip valves ensure that no spraying is done while turning at the end of the row. The wide selection of ceramic nozzles gives the operator excellent control over application rates and droplet sizing, ensuring maximum coverage with a minimum of drift.
|
| Superior tank design |
| |
Hardi uses polyethylene for tank manufacturing. Polyethylene offers a number of key advantages compared with other tank materials. Polyethylene is extremely strong and flexible ensuring that the tanks can withstand any kind of vibration. The use of polyethylene gives Hardi the capabilities to design tanks that are very compact, narrow and molded in specific shapes to optimize overall design and performance. The tanks are designed to rest on the frame in their full length. They are held in place by the front sub-frame and fan assembly, eliminating the need for tank straps. All Hardi tanks are mad of seamless UV protected polyethylene. They are specifically designed to resist abrasive chemicals and liquid fertilizers used in agriculture all over the world. All tanks are puncture resistant and designed with large deep sumps for optimal pump priming, cleaning, agitation and complete emptying on slopes and side hills.
|
| Patented centrifugal fan clutch |
| |
The fans are engaged via an over-running centrifugal clutch in order to provide smooth fan acceleration. The clutch helps protect the tractor, the drive lines, the pump and the gearbox from the extremetorque peaks created when the sprayer is engaged very abruptly.
|
| Gear Box |
| |
The Arrow is equipped with heavy duty 1-speed gearbox with neutral position as standard. The gearbox has remote oil filling for easy maintenance.
