Hydrostatic technology – fast response, speed control and higher power density.
HARDI uses hydrostatic drives in all its self-propelled sprayers. Widely recognised as an excellent means of power transmission, this technology has a number of advantages over a mechanical drive, such as fast response, speed control and higher power density.
The versatility of hydraulics controls speed, torque and power to closely match immediate requirements. Hydraulic motors, cylinders and rotary actuators are powerful and compact, giving them a much higher power density than other forms for power transmission.
Hydraulics deliver superior ground clearance – because the operator does not need to run drive shafts to wheels – and high torque, essential for driving large-diameter wheels up and down inclines and through mud.
While recognising a few benefits of mechanical drives, such as slightly lower fuel and maintenance cost (the main argument for the Goldacres self-propelled sprayers), HARDI believes hydrostatic drives offer the optimal performance for the advanced spec'd HARDI self-propelled machines.
