Improvements to Hardi air-assisted sprayer units for vineyard treatment

Hardi-Evrard is upgrading the air-assisted sprayer unit commonly fitted to straddle tractors, grape harvesters and various other self-propelled units designed for viticulture applications, in order to stay one step ahead of comfort, safety and technical requirements for its equipment in view of the future environmental amendment to the Machinery Directive.

Hardi air-assisted sprayer units, now recognized and proven for their distribution quality, see their basic version enhanced with an ?environmental kit? to improve operator comfort and ease of use in a context of reasoned vineyard spraying.

As a result, technical components that have enjoyed a certain success in field crops have been integrated into the Hardi air-assisted sprayer unit.

As an option, the multi-function handle, usually fitted to equipment in the Evrard range, controls all the spraying functions (general on/off, section on/off, volume/ha variation) and all the hydraulic boom functions (up/down, variable geometry, slope corrector and arm unfolding/folding) for optimal working comfort during applications.

The Hardi Manifold valves used to operate the spraying functions are now intuitively grouped on the left side of the fan unit.

In addition, the TurboFiller product incorporator, with a capacity of 25 or 35 liters, is now offered to make mixing and incorporation easier on this equipment, which is often very tall and difficult and dangerous to access.

The TurboFiller has a high mixing capacity for powder and liquid formulations thanks to the use of strong suction and the vigorous vortex created by the Turbo deflector in the hopper.

It is fitted with a cleaning device, made up of a hose and a trigger, which allows the hopper to be rinsed or a container of plant protection products to be filled.

Hardi-Evrard also offers different types of agitation (twin Venturi nozzles or Venturi cannon) to homogenize mixtures during treatments, as well as a rotary rinsing nozzle, which can be fitted to any type of main tank to improve the speed and efficiency of rinsing at the end of application.

Finally, among the many innovations and adaptations offered on the Hardi unit, a quick manual row-spacing adjustment is now fitted as standard on each spray drop in order to adapt quickly to different vineyard topographies and to make it easy to reproduce settings according to growth stages.

Adaptable to the different types of straddle tractors on the market in full compliance with the safety and environmental rules in force, the new Hardi air-assisted sprayer unit, resolutely high-end, is positioned for the future with the most demanding wine-growing estates.
