Longer spraying days and nights and higher spraying speeds place heavier demands on comfort and easy operation. HARDI renews the self-propelled sprayer ALPHA family to 3500 and 4100 l with ambitious specifications in terms of better performance, reliability and driving comfort and adds higher tank volume up to 5100 l.
ALPHA evo features a fine balance between front and rear and has a low total weight giving an optimal weight/capacity ratio and high performance even under wet field conditions. Also the high ground clearance from 120 to 165 cm gives a flexible usage from low to tall crops as sweet corn and sunflowers.
The new large spacious EvoCab II is specifically developed by HARDI with its “3-pillar design”, which provides a new standard for visibility with more than 320° around the sprayer.
The cabin is equipped with a pressurisation system, a dust filtering of fresh air, an aerosol and vapor filtering to protect the driver and fulfill the Class 4 requirements.
The new climate control system has been tested intensively in climate chamber in order to bring highest driver comfort in warmest condition.
By equipping the ALPHA with the optional FloatRide, the standard coil spring suspension is replaced by airbags. This ensures even more boom stability and maintains balance of the ALPHA in strong slope. The chassis’ height will be maintained whatever tank volume. By allowing for individual wheel movement, the ALPHA provides a maximum comfort, even at high spraying speeds through a wheel travel of 185 mm.
Water-cooled 6-cylinder inline engines with turbocharging, charge air cooling and cooled external exhaust gas recirculation. Two-stage turbocharging for the highest performance requirements. Engine and exhaust aftertreatment (EAT) are optimised for highest total system efficiency and thus ensure minimised fuel and total operating costs. The powerful DEUTZ Common Rail (DCR®) injection system and the electronic engine control (EMR 4) with intelligent link to the drive management (EcoDrive) ensure optimum engine performance at low fuel consumption.
The ALPHA evo EcoDrive with FloatRide suspension can be equipped with Hydraulic Track width Adjustment. This Hydraulic Track width Adjustment axle allows a track width from 180 to 280 cm (depending on tire dimensions).
The driver will set his track width from the cab display and will be ready to drive. That will allow changing track width from the road to the field and from cereal crop to maize, row crop or vegetable with a variation of 1 m between minimum and maximum.
