HARDI introduce new smaller ALPHA self-propelled
A specific feature of the new ALPHA 3000 is its VARITRACK hydraulic track width adjustment system. Using the in-cab digital control unit, stepless track width can be achieved whilst on the move over 45cm from a minimum of 1.80m out to 2.25m (on 270/95R38 tyres). The digital display provides the operator with a readout to the actual track width and avoids the need to physically measure the track width.Unlike other systems that use sliding axle designs, the VARITRACK system is safer and faster, plus it has no sliding components. VARITRACK is suitable for use at road-speeds of 40km/h and does not require the wheel settings to be re-aligned after the axle has been adjusted. Where a hydraulic system is not required, a manual adjustment system can be specified, which again is substantially quicker to adjust than other manual types.The ability to quickly and simply change the track width will obviously be an attraction for contractors or for farms where root crops or vegetables are grown, but the system also offers the potential to provide greater stability on the road.The ALPHA VARITRACK is powered by a 170hp, 6-cylinder turbo-charged DEUTZ engine. Drive to all four wheels is hydrostatically controlled via a multifunction joystick and a five-way dashboard control with park/transport/field/hill climb/hill descent functions. Each wheel is driven using three-speed Poclain hydraulic motors which have a maximum road speed of 40kph. The sprayer is also fitted with the foot operated DYNAPLUS safety braking system, which acts on each wheel for 4-wheel braking.For operators who do not require such a high road speed, a 25kph hydrostatic transmission is also available, powered by a 140hp 4-cylinder turbo-charged DEUTZ power unit.The cab on the ALPHA VARITRACK offers excellent all-round visibility from the driving position and is fitted with both air-conditioning, automatic cab pressurisation and active carbon filters. All the main operating controls are grouped on the multi-function joystick, whilst the fluid system is controlled using a HARDI REGULOR 5 computer control system. Amongst its many functions, this provides:
• Electronic control regulation for constant application rate regardless of speed.
• Flow; pressure or automatic regulation
• Boom section and control valve position display
• 100 job data memory
• GPS, radar and printer compatibility.
• Automatic boom lift on the headlands (option)The new ALPHA VARITRACK is immediately available and prices start at £63000 for a 24m, 25kph, 2500 litre, 140hp machine with manual VARITRACK. What is expected to be the 'standard' best-selling model with 24m booms, 40kph, 3000 litre, 170hp with hydraulic VARITRACK costs £74,000.
