Anti-lock braking systems for cars and lorries are now commonplace. But the added complications of heavy mounted articulated equipments, uneven terrain and a huge amount of variation in traction conditions, even from wheel to wheel, means that an effective antilock braking system for tractors requires more advanced development. New Holland has won a silver award for its ABS SuperSteer™ - a smart application of ABS technology to tractors, which not only offers confident stopping power with increased safety, but also increases tractor manoeuvrability and improves safety when operating on steep hills.
ABS SuperSteer™ uses ABS technology to manage each wheel’s brake individually. This new feature will be available on current and future New Holland high power, high speed tractors like the T7000 Auto Command. ABS SuperSteer™ will enable a new generation of 60kph-capable, front-axle suspension tractors achieve an outstanding level of field agility and comfortable ride control.
New Holland’s pioneering SuperSteer™ axle remains available on New Holland’s range of tractors from 40 to 325hp but is limited to a top speed of 40 kph.
Using a single foot pedal, the ABS SuperSteer™ allows the tractor to be steered by the brakes. Two orange pedal extensions either side of a single pedal replace the conventional, independent two-pedal arrangement. At low speed, this provides the driver with the same single-wheel steering as a conventional tractor, but automatically disables at higher speeds to prevent accidental application.
The ABS SuperSteer™ function includes tyre slip control and automatic coupling with the steering angle. This allows the tractor to perform tight turning manoeuvres without driver intervention on brakes by pivoting on a braked rear wheel, reducing the turning circle to that of a tractor fitted with a SuperSteer™ front axle. A driver-selectable amount of slip on the pivoting wheel is allowed to prevent soil damage.
The hill holder function improves tractor control on slopes, automatically engaging the brakes to prevent the machine rolling back during hill starts and easing clutch engagement.
