Hydrostatic drive
Highlight
Viroc achieves impressive traction through a state-of-the-art hydraulic all-wheel drive with radial piston motors specifically developed for agricultural use.
Plus
Two hydrostatic variable piston pumps manage forward and reverse motion, one for the right and one for the left wheels. Speed is continuously adjustable from 0 to 20 km/h / 0 to 12 mph) using a single pedal. Switching between forward and reverse gears is easily done via a joystick switch. The High-Torque version, if desired, allows for boosting pulling power from 13,300 N to 20,000 N. However, the top speed is reduced to 14 km/h / 9 mph.
For tasks requiring steady speed, an electronic cruise control provides consistency and thus enhanced productivity — particularly when using accessory units such as sprayers or mowers. Speed is precisely managed through a dial on the joystick, regardless of the diesel engine’s RPM.
Viroc’s hydraulic differential lock prevents the wheels from spinning thanks to a system that evenly distributes the oil and, thus, the driving power to all four wheels in extreme situations. The differential lock can be engaged or disengaged in a fraction of a second, even under full load, using a button on the joystick or the control panel below the steering wheel.
The four spring-loaded brakes, one on each drive wheel, ensure a safe stop when the designated switch on the joystick is set to zero, the operator leaves the seat, or the engine is turned off.
